Bayou K, Terefe G, Kumsa B. Gastrointestinal parasites of owned cats in three districts of Central Ethiopia: Prevalence and risk factors. Vet Parasitol Reg Stud Reports 2024; 52:101053. [PMID: 38880580 DOI: 10.1016/j.vprsr.2024.101053] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2023] [Revised: 05/13/2024] [Accepted: 05/31/2024] [Indexed: 06/18/2024]
Abstract
This present, cross-sectional study investigated gastrointestinal parasites in owned cats was carried out across Bishoftu, Dukem, and Addis Ababa city and towns in Central Ethiopia from February 2022 to April 2023. The primary objectives were to estimate the prevalence and assess the risk factors associated with these parasites. A total of 213 faecal samples were collected and processed using flotation and McMaster techniques. An overall prevalence of 34.7% (74/213) of gastrointestinal parasites was recorded in the examined cats. The cats harboured nematode (14.6%), cestode (12.7%), and protozoan (5.6%) parasites in single (32.9%) and mixed (1.9%) species. Specifically, Toxocara cati, Dipylidium caninum, Taenia spp., Giardia spp., and Physaloptera spp. were the more frequently identified parasites, with prevalences of 9.4%, 8.9%, 3.8%, 2.8%, and 2.8%, respectively. Statistically significant differences (P < 0.05) were observed in the prevalence of gastrointestinal parasites among cats of different sexes, ages, and feeding conditions. Thus, higher prevalence rates were observed in females (49.1%, OR = 2.3), young cats (70%, OR = 4.7), and those consuming uncooked food (40.5%, OR = 3.6). Faecal consistency also showed a statistically significant association (P < 0.05) with the presence of gastrointestinal parasites. However, no significant differences were noted in the prevalence among cats of different housing conditions, seasons, or agro-ecological zones. Cats sharing shelter with families had the highest prevalence of gastrointestinal parasites (52.2%). In conclusion, this study uncovered a notably high occurrence of gastrointestinal parasites in cats in the surveyed regions, emphasizing the imperative of adopting a One Health strategy to address the zoonotic parasites found in cats, which pose significant public health risks.

Elshahawy IS, Fawaz M, Gomaa A, Mohammed E. Prevalence and first molecular identification of Sarcocystis species in feces of domestic dogs (Canis familiaris) in Egypt. BMC Vet Res 2023; 19:278. [PMID: 38110960 PMCID: PMC10726512 DOI: 10.1186/s12917-023-03841-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2023] [Accepted: 12/01/2023] [Indexed: 12/20/2023] Open
Abstract
BACKGROUND Sarcocystis species are obligatorily heteroxenous protozoan parasites with predator-prey life cycles. Global Knowledge about the epidemiology and the distribution pattern of different Sarcocystis species in dog feces are very scarce. Therefore, the current investigation was conducted to declare the occurrence of Sarcocystis in the fecal specimens of the most common canids in Egypt, the domestic dogs, and to identify the species present using various parasitological and molecular approaches. METHODS A total of 100 dog fecal samples were collected and screened using fecal sugar flotation test for the presence of Sarcocystis oocysts/sporocysts. Additionally, thirty samples were used for genomic DNA extraction. The 18S rRNA gene fragment was the target of primers for a PCR, followed by purification and sequencing of the amplicons. RESULTS Currently, the results obtained reviewed that 4% of fecal samples were positive for Sarcocystis spp. using LM. Additionally, Sarcocystis spp. were verified in sixteen dogs (53.3%, 16/30) using PCR and subsequent sequencing protocols. Statistically, insignificant difference in prevalence of sarcocystosis relative to age and gender was noticed. Morphologically, the detected sporocysts measured 13.2-16.0 × 9.4-11 μm. Based on the 18S rRNA gene, sequencing analysis of amplicons from sporocysts DNA revealed 99.82% nucleotide homology with published S. tenella partial nucleotide sequences from sheep in Iraq and Iran. CONCLUSIONS This is the first molecular evidence in support of the final host role of domestic dogs in the life cycle of S. tenella in Egypt, which provides a precious diagnostic tool for further epidemiological studies and for the assessment of the effectiveness of control measures for this disease.

Abstract
Giardia duodenalis infections are common in dogs and are mainly caused by assemblages C and D. The aim of this study was to investigate the correlation between the presence of Giardia duodenalis and different Giardia assemblages detected in symptomatic and asymptomatic dogs and the occurrence of certain clinical signs. All the dogs included (n = 82) were clinically examined, and fecal samples were examined for other parasites and Clostridium spp. Also, G. duodenalis assemblages were detected and the occurrence of certain clinical signs was assessed. A total of 42/82 (51.2%) dogs were symptomatic and had one or more gastrointestinal signs, and 40/82 (48.8%) dogs were asymptomatic. G. duodenalis was found in 25/82 (30.5%) dogs: assemblage C in 10/25 (40%) and assemblage D in 15/25 (60%). Only Cryptosporidium spp. showed a higher coinfection rate with G. duodenalis but that did not have an influence on clinical sign appearance. There was no correlation between the presence of different assemblages of G. duodenalis and the sex of the host or the duration and appearance of certain clinical signs, except the presence of mucus in feces, which was more frequent in dogs invaded with G. duodenalis assemblage C. Further research of other assemblages is needed.

Abstract
Dogs are popular pets around the world and have always had a very close relationship with humans. Zoonotic gastrointestinal helminth parasites are a great threat to both stray and pet dogs. This study was carried out to determine the prevalence of zoonotic gastrointestinal helminths in dogs. 400 samples were collected, including 200 from pet dogs and 200 from stray dogs. The samples from pet dogs were collected from the ground immediately after voiding with the help of the owner, whereas stray dogs were caught by using a dog catcher, and the samples were collected directly from the rectum by using a gloved index finger. All collected samples were examined under a microscope using sedimentation and flotation techniques. The overall prevalence of infection was found to be 59.50%, with a significantly higher prevalence in stray dogs (70%) than that in pet dogs (49%). Ancylostoma spp., Toxocara spp., Trichuris spp., Capillaria spp., Dipylidium caninum, and Taenia/Echinococcus spp. were six different species found in the current study. The study showed the highest prevalence of Ancylostoma spp. (49.16%) and the least prevalence of Capillaria spp. (0.84%). In the age-wise study, puppies had a significantly high infection rate (86.96%). Similarly, we recorded a significantly higher prevalence of intestinal helminths among nondewormed pet dogs (78.65%) than among dewormed pet dogs (25.23%). This study highlights the severe environmental contamination shed by dogs, causing a higher risk of zoonotic transmission. It indicates the urgent need to manage these parasites in dogs and educate the public on how to care for their pets and the parasites they shed.

Abstract
Understanding the epidemiology of canine parasitic infections, gastrointestinal helminthic infections in particular, is crucial for designing an efficient control programs targeted at minimizing the risks of zoonotic transmission. A total of 470 dogs attending veterinary clinics in Northeastern Nigeria were screened for gastrointestinal helminths using standard parasitological techniques. Epidemiological risk factors associated with the canine parasitic infections were assessed using multivariable logistic regression analysis. In total, 77.9% (366/470) of dogs had harboured one or more species of the gastrointestinal helminths: Ancylostoma caninum (40.2%), Toxocara canis (35.1%) Trichuris vulpis (26.6%), Spirocerca lupi (5.7%), Taenia/Echinococcus (12.3%), Dipylidium caninum (10.9%) and Diphyllobothriid ova (2.8%). Female dogs (OR=2.1; p=0.02), local breeds (OR=2.3; p<0.01), younger dogs (OR=3.2; p<0.001), dogs adopted as security guards (OR=1.8; p<0.01) and poor body condition score (OR=3.1; p<0.001) were strongly associated with A. caninum infection. For T. canis and T. vulpis, younger dogs (OR=2.5; p=0.02 and OR=2.3; p<0.01) and poor body condition score (OR=4.2; p<0.001 and OR=2.2; p<0.01) were the strong predictors for infection, whereas female dogs (OR=2.8; p=0.02), younger dogs (OR=4.1; p<0.001) and poor body condition score (OR=4.0; p<0.001) were strongly associated with D. caninum infection in dogs. The results revealed high prevalence of gastrointestinal helminths-some of which have zoonotic potential-among dogs underlying huge public health risk.

Abstract
Dog feces may contain zoonotic parasites that contaminate the environment and serve as a potential source of infection to animals and humans. In this study, microscopic and molecular analyses were used to estimate the prevalence and intensity of gastrointestinal (GI) parasites and assess the risk factors for infection in 948 dogs in three climatically distinct zones of Nigeria. Zoonotic helminths including Strongyloides stercoralis, Ancylostoma braziliense, A. caninum and Toxocara canis were detected either as single or multiple infections in 377 (39.8 %) of dogs examined. At multiple logistic regression analyses, association was found between GI parasite infection and deworming practices and dog management. Regarding A. braziliense, A. caninum and T. canis infections, intensity of egg shedding was statistically associated with the age of the dogs and not with their sex or breed. The majority of GI parasite-positive dogs did not receive regular deworming treatment (59 %) and roamed freely (56 %) thereby constituting public health risk. This is the first nationwide survey and analyses of risk factors of GI parasites of dogs using molecular methods as confirmation of their identity. The zoonotic potential of these parasites is exacerbated by the lack of both operational national policies to control the population of free-roaming dogs and to promote responsible dog ownership, and veterinary public health programs for dogs.

Parasitic helminth infections of dogs, wolves, foxes, and golden jackals in Mazandaran Province, North of Iran. Vet World 2020; 13:2643-2648. [PMID: 33487982 PMCID: PMC7811556 DOI: 10.14202/vetworld.2020.2643-2648] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2020] [Accepted: 10/27/2020] [Indexed: 11/16/2022] Open
Abstract
Background and Aim: There is a large amount of information on intestinal parasites in stray dogs and golden jackals (Canis aureus) in Mazandaran Province, Iran. However, there is little information about foxes and wolves, which have a potential role in the spread of dangerous parasitic diseases, such as echinococcosis and toxocariasis. The aim of the present study was to identify the genus or species of parasitic worms in stool samples obtained from carnivores in Mazandaran Province, Iran, from August 2017 to April 2018. Materials and Methods: A total of 274 fecal samples were collected from carnivores, including dog, fox, wolf, and C. aureus in three areas of Mazandaran Province, Iran. All specimens were examined by centrifugal fecal flotation using a solution of Sheather’s sugar to detect helminths eggs. Then, all samples were assessed using a light microscope. Data analysis was performed by SPSS version 18 (Chicago, IL, USA). Results: In this study, seven genera of helminths were observed, including Ancylostoma, Uncinaria, Toxocara, Dipylidium, Toxascaris, Taenia, and Spirocerca. The prevalence of helminth infections was 97.7% (127 out of 130), 56.7% (51 out of 90), 51.4% (18 out of 35), and 52.6% (10 out of 19), among dogs, C. aureus, foxes, and wolves, respectively. The highest prevalence of Ancylostoma and Toxocara infections occurred in the eastern and central areas of the province (42.1% and 35.7%, respectively). Conclusion: Based on the results of this study, the infection with intestinal zoonotic helminths in carnivores was an important public health factor in Mazandaran. Therefore, these infections can be potentially harmful to humans and other animals.

Abstract
Faecal (2,250) and blood samples (1,350) of dogs received from Teaching Veterinary Clinical Complex (TVCC), Gannavaram, Veterinary Hospitals in and around Krishna district and nearby Krishna, Andhra Pradesh during last five years (January 2014 to December 2018) were examined to determine the prevalence of protozoan parasites. Faecal samples were analyzed by direct smear and floatation technique and blood samples after Giemsa's staining. The overall prevalence of protozoan parasitic infections including intestinal (15.60%) and haemoprotozoan (6.22%) infections was 12.10% (n=435). Six genera of protozoan parasites namely Cystisospora, Entamoeba, Ehrlichia, Trypanosoma, Babesia and Hepatozoon were identified. The most prevalent species was Cystoisospora (14.04%) and Hepatozoan canis (0.67%) was the least prevalent species. A significant relationship between age group, breed and prevalence of protozoan parasitism was observed. The prevalence of gastrointestinal and haemoprotozoan parasites was significant during winter and rainy seasons, respectively. Sex did not influence the overall prevalence of protozoan parasites.

Abstract
Dogs are the most common companion animals worldwide. They are among the main reservoirs, carriers, and transmitters of many infectious and parasitic diseases. A cross-sectional study was conducted in Ambo, Bako and Gojo towns of West Shoa Zone, from January 2015 to June 2017 with the objectives of estimating the prevalence and associated risk factors of gastrointestinal helminths of dogs. Chi-square and logistic regression analyses were used for data analysis. P-value of <0.05 was considered significant. Out of 310 dogs sampled and subjected to faecal examination using flotation and sedimentation methods, 158 (50.97%, 95% confidence interval [CI]: 45.26-56.66%) of the dogs were positive for helminths infection. The study identified Ancylostoma caninum (36.8%), Toxocara canis (9.7%), Uncinaria spp. (4.5%), Physaloptera canis (4.5%), Salminicola canis (3.22%), Oncicola canis (1.9%), Spirocerca lupi (0.3%), T. leonina (1.0%), Trichuris vulpis (0.97%), Diphyllobothrium (1.29%), Taenid spp. (0.3%), and Mesocestoides spp. (0.3%). Out of the 243 male and 67 female dogs examined, 123 males (50.6%) and 35 females (52.2%) were positive for one or more gastrointestinal helminths. There was no significant difference (p > 0.05) in the overall prevalence of helminth infections between sexes, age, breed, district and management of dogs. From the total positive dogs, 123 (39.7%) had a single infection while 36 (11.6%) of dogs had mixed infection. The odds of acquiring T. canis was 4.88 times higher in dogs of Gojo (p = 0.004) as compared to Bako town. The probability of acquiring T. canis infection was 4.49 times higher in juvenile dogs (p = 0.012) as compared to adult dogs. The prevalence of gastrointestinal helminths of dogs in Ambo, Bako, and Gojo towns was high. The diversity of the helminth parasites detected together with their zoonotic importance calls for the need of regular deworming and training of dog owners to create awareness about transmission, clinical signs, prevention, and control of helminth parasites.

Abstract
The toxocariasis incidence in Russia is relatively low (1.8 cases per 100,000 individuals) and the parasite is not a major healthcare concern. However, the proportion of primary hosts testing positive for the parasite is high and varies between 3% and 100% in dogs (on average 33%), and between 6% and 52% in cats. Higher prevalence was observed in Volga, Urals and Siberia regions. Levels of contamination of soil, children's playgrounds and sandboxes is also high, with up to 100% contamination rates determined in some studies, but more commonly prevalence of contamination around 40% was reported. There is a pronounced seasonality in the prevalence of Toxocara in primary hosts and the soil, with peaks in the summer and autumn. Most likely, a lack of permissive conditions for the development of eggs in the winter determines observed seasonal patterns, which are different than those observed in most other countries. Toxocara eggs were found in 4-10% of vegetables and greenery samples tested, suggesting that they can contribute to the transmission of Toxocara.

Abstract
Toxocariasis is a worldwide anthropozoonosis caused by Toxocara spp. nematodes. High prevalences of the disease has been found in developing countries, particularly in regions with poor sanitary conditions. The definitive hosts of the nematodes are dogs and cats, which play a vital role in the transmission of this parasite as humans are considered a paratenic host. The epidemiology of the disease in South America is not clear as it is usually not diagnosed and is not a notifiable disease. This review summarizes information regarding prevalence reports of Toxocara spp. in dog and cats in South America (excluding Brazil). Additionally, and in accordance with the one health approach, reports of contaminated soil in public zones and parks as well as infection/prevalence reports in wildlife species by geographical regions are also included. The findings show the importance of awareness among veterinarians and public health authorities about Toxocara spp. as neglected disease.

Abstract
Although many studies on the frequency of endoparasites in dogs and cats in Canada have been reported, seasonal and/or annual patterns are often not evaluated. The frequency and risk factors of endoparasite infections from fecal samples of cats and dogs submitted to the Veterinary Teaching Hospital of the Atlantic Veterinary College, University of Prince Edward Island-Canada were determined, using univariable and multivariable logistic regression analyses. Investigated predictors of endoparasitism available in the 2000-2017 database included sex, age, geographic origin and seasonality. A total of 15,016 dogs and 2,391 cats were evaluated for endoparasite status using specific diagnostic tests: direct smear, Baermann, and/or 33 % zinc sulfate solution in a standardized centrifugal flotation method. Overall, twelve and eight parasite genera were detected in dogs and cats, respectively. The overall proportional infection was 14.6 %, and the cat population showed a higher frequency of positivity to parasites compared to the dog population (P < 0.001). The most frequent genera recovered in the whole population (dogs and cats), were Giardia duodenalis (5.2 %), Cystoisospora spp. (3.3 %) and Toxocara spp. (3.2 %). Endoparasitism levels were diagnosed more in feces submitted from young, female intact dogs from PEI compared to the baselines of mature, sterilized male dogs from other provinces, respectively, and diagnoses occurred more often in autumn months than in winter months. There was no significant diagnostic trend across the years for the individual parasites models. The frequency of detected potentially zoonotic parasites in this study highlights the veterinary public health and One Health context of parasitic infections in pets. Although the presented results are not from a random sample and therefore frequency results should be interpreted with caution, the model relationship results may still be relevant. In addition, results are of value to estimate parasite impact and to assist researchers, veterinarians and pet-owners with suitable information to control parasites.

Abstract
Data on environmental contamination of the parasites of zoonotic importance is scarce in Pakistan. Soil contamination with feces of dogs hide infective stages of the parasite represents a health-risk to humans. This study was aimed to assess the eggs of gastrointestinal parasites of stray dogs and household dogs in lower Dir district, Pakistan with special consideration to those that can be spread to humans. One hundred and fifty two stool specimens from (stray dogs=90 and household dogs=62) were collected. The helminth eggs were processed by direct smear method and centrifugation techniques and identified by microscopic examination. Of the total examined dogs 26.8% (n=41 /152) were found to be infected with one or more intestinal parasites. The intestinal helminths detected were Dipylidium caninum (n =18, 11.8%), followed by Toxocara canis (n =16, 10.5%), Taenia spp., (n=10, 6.57%) Ancylostoma caninum (n=6, 3.94), Toxascaris spp., Capillaria spp., and Trichuris vulpis (n=2, 1.31% each) in order of their prevalence. Pattern of infection revealed that 27 (65.8%) dogs have single, 13(31.7%) double and 1(2.43%) triple infection. The stray dogs were highly infected 34.4% (n=31) than house hold dogs 16.1% (n=10). The prevalence of infection with intestinal parasites was significantly different among these two groups (p = 0.0097). This study highlight a severe environmental contamination by frequent parasitic stages infectious to humans. There is a higher risk of zoonotic transmission from dogs which indicate an immediate need for the controlling of these parasites and educating the public to take wise action relating to the parasites and pets.

Abstract
Abstract
Canine fecal contamination in public green areas is difficult to control. Our objectives were to assess: (i) the relationship between fecal contamination in public green spaces of Buenos Aires (Argentina) and the type of green space (boulevard/square/park), considering their area, presence/absence of control measures, and human population density in the surroundings (high or low); (ii) the perception of people of such contamination and (iii) the frequency of parasites in dog feces. In each green space (n = 26), feces were counted in thirty 25-m2 plots randomly located. The opinion survey consisted of asking people (358) what their perception of fecal contamination was, whether it bothered them and whether they thought it was hazardous to the dogs’ or people’ health. Canine fecal samples randomly collected (n = 112) were concentrated and examined microscopically. Mixed-effect generalized linear models were fitted to evaluate the effect of selected variables on fecal contamination. People’s perception of human and canine health risks were assessed by logistic regression. Canine fecal contamination was lower in squares with control measures and in parks with control measures located in densely populated areas, and higher in boulevards located in densely populated areas. The visitor’s perception was that feces were associated with dirtiness (77%) and odor (30.8%). Parasites were detected in 51.8% of fecal samples. Our results confirm that environmental control measures decrease canine fecal contamination of public green spaces, and that more than 65% of the people interviewed do not relate fecal contamination to risks to human/dog health.

Abstract
Aim: This study was designed to investigate the prevalence, associated risk factors, and zoonotic implications of gastrointestinal parasites of dogs in Maiduguri, Borno State, Northeastern Nigeria. Materials and Methods: A total of 200 rectal fecal samples were collected from dogs in Maiduguri for coprological examination using the saturated sodium chloride floatation technique. Detection of eggs or oocyst was done on the basis of keys of identification of parasites based on the morphology and size of eggs or oocyst. Results: The prevalence of gastrointestinal parasites of dogs was 31.5% (63/200) in Maiduguri. The prevalence of the infection was higher in young, male dogs kept outdoor in terms of age, sex, and management; the difference was statistically significant (p<0.05). The parasites detected in Maiduguri include Ancylostoma spp., Toxocara spp., Dipylidium spp., Isospora spp., and Taenia spp., with Ancylostoma spp. (16%) having the highest prevalence rate. Conclusion: Gastrointestinal parasites have high prevalence in Maiduguri and constitute potential risk to human health because all genera of parasites detected in the study area are of public health importance.

Abstract
Toxocariasis is a zoonotic disease with a worldwide distribution caused by the parasitic roundworms, Toxocara canis, commonly found in the intestine of dogs. Identification of frequent shedders for Toxocara canis eggs and the associated risk factors overwhelmingly remain an important cornerstone of conducting evidence-based deworming regimens to reduce the environmental contamination with the parasite eggs. The present study was undertaken to prevalence rate of shedding of Toxocara canis eggs in dogs in Egypt combined with the possible risk factors naturally associated with the infection A total number of 296 fecal samples of dogs were collected in the period from July 2016 to June 2017 and properly screened for the presence of possible infection with an. Importantly, The overall prevalence of Toxocara canis eggs was 53.04% whereas, seasonal dynamics, dog breeds, the irregular anthelmintic use, defecation sites, and unconfined management of dogs were among the risk factors with a significant association with Toxocara canis infection. Taken together, our present data reveal the high overall prevalence of Toxocara canis eggs shedding in in several Egyptian provinces and provide novel information that should pay our attention of the local authorities combined with the public engagement towards implementation of effective control strategies against this disease of zoonotic importance.

Abstract
The objective of the present study was to evaluate the contamination of sewage sludge produced by municipal waste treatment plants in Poland by viable eggs of intestinal parasites of the genera Ascaris, Toxocara and Trichuris (ATT). Ninety-two municipal, mechanical-biological sewage treatment plants located within Poland were selected. These plants belonged to types of agglomerations: group 0 (large), group 1 (medium), group 2 (smaller) and group 3 (small). Samples were collected at the final stage of sewage treatment after the addition of flocculent to sludge, followed by dehydration. The samples were examined by a method adjusted to examine sewage sludge dehydrated using polyelectrolytes. The viability of the isolated eggs was evaluated based on incubation in a moist chamber. Live eggs of intestinal nematodes were found in 99% of samples. Most samples were contaminated by the eggs of Ascaris spp. (95%) and Toxocara spp. (96%). However, Trichuris spp. eggs were detected in 60% of samples. The mean number of eggs in 1 kg of dry mass (eggs/kg d.m.) was 5600 for Ascaris, 3700 for Toxocara and 1100 for Trichuris. The highest number of ATT eggs was detected in samples from sewage treatment plants located in south-eastern and central Poland. The highest number of ATT eggs was found in sewage sludge produced in large sewage treatment plants (agglomeration Groups 0 and 1), with mean values of 15,000 and 8900 eggs/kg d.m. The present study is the first parasitological investigation conducted on a large number of samples (92 samples) taken from various types of municipal sewage treatment plants located throughout Poland (16 regions) after the common introduction of polyelectrolytes during sewage sludge dehydration. The results of this study indicate that sludge produced in municipal sewage treatment plants is highly contaminated with parasite eggs.

Abstract
A cross sectional study was designed to ascertain the prevalence of zoonotic helminths and protozoan parasites in dogs by employing conventional techniques and molecular characterization using polymerase chain reaction (PCR). Companion animals are reservoir hosts for helminths and protozoa species, and cohabitation with humans play a pivotal role in the transmission of zoonotic parasites to humans. A total of 510 faecal samples were collected from pet dogs belongs to various zones of Chennai city, Tamil Nadu, India and were processed by conventional techniques and molecular techniques. Out of 510 dog faeces, 121 samples were found positive for the parasitic eggs, prevalence rate was found to be 23.72%. Species-wise prevalence of the parasite was tabulated. PCR for the species-specific identification of the parasitic eggs was performed. The results revealed 38 samples were positive with product size of 540 bp specific for Ancylostoma caninum, 25 samples were positive which yielded a product size of 380 bp which is specific for Toxocara canis. None of the faecal samples tested were positive for Echinococcus granulosus which were positive for the presence of Taenia spp. eggs by microscopy. We recommend prevention and control measures focused on improving regular deworming, enhancing awareness of parasitic zoonotic diseases to minimize the transmission risk of parasitic zoonotic diseases from companion animals to humans. PCR can be widely used for species-specific identification of the zoonotic parasites.

Abstract
Dogs entering shelters can carry gastrointestinal parasites that may pose serious risks to other animals, shelter staff and visitors. Shelters provide an environment that could facilitate the spread of parasitic infections between animals. Nematodes and protozoa that transmit through ingestion or skin penetration are major enteric parasites of concern in shelter settings. Ancylostoma spp., Uncinaria stenocephala, Toxocara canis, Toxascaris leonina, Trichuris vulpis and Dipylidium caninum are the major helminths while Giardia, Cryptosporidium, Isospora spp. and Sarcocystis spp. are the most prevalent protozoan parasites in shelter dogs. The prevalence of gastrointestinal parasites in shelter dogs is typically higher than in owned dogs. A range of cost-effective drugs is available for prevention and control of helminths in shelters, notably fenbendazole, pyrantel, oxantel, and praziquantel. Parasiticide options for protozoan parasites are often cost-prohibitive or limited by a lack of veterinary registration for use in dogs. Environmental control measures reliant upon hygiene and facility management are therefore a mainstay for control and prevention of protozoan parasites in shelters. This philosophy should also extend to helminth control, as integrated parasite control strategies can allow anthelmintics to be used more sparingly and judiciously. The purpose of this article is to comprehensively review the current knowledge on the prevalence of gastrointestinal parasites most commonly found in dogs in shelters, canvass recommended treatment programs in shelter dogs, and to explore the likelihood that parasiticide resistance might emerge in a shelter environment.

Abstract
Aim: Cryptosporidium is one of the causes of diarrheal illness in man and animals worldwide and is zoonotic. The study aimed to determine the prevalence and risk factors associated with fecal shedding of Cryptosporidium oocysts in dogs in Lusaka district of Zambia. Materials and Methods: A cross-sectional study was conducted in Lusaka district of Zambia during 2015-2016. A total of 390 dogs (243 males and 147 females) aged 2 months-13 years were enrolled. Fecal samples were collected and stained using modified Ziehl-Neelsen and Auramine O staining techniques and examined microscopically for oocysts. Results: Overall, the prevalence of Cryptosporidium oocysts infection was 5.9% (23/390; 95% confidence interval: 3.9-8.7). Prevalence among male dogs and female dogs was 5.3% and 6.8%, respectively. Older dogs had a relatively higher infection rate compared to the younger puppies. There was a statistically significant difference in infection between nondescript breed and pure breeds with prevalence being higher in nondescript dog breeds. Water source was also significantly associated with Cryptosporidium infection. Conclusion: Cryptosporidium infections are common, especially among the nondescript breed of domestic dogs in Lusaka district of Zambia. Further studies to characterize the common species are warranted.

Abstract
OBJECTIVE To determine the prevalence of selected intestinal parasites in pet dogs and recently apprehended free-roaming (AFR) shelter dogs in the Phoenix metropolitan area and compare those prevalences between the 2 groups. DESIGN Cross-sectional study. SAMPLE Convenience samples of fecal specimens from owned pet dogs from the Phoenix metropolitan area (n = 175) and free-roaming dogs apprehended and admitted to Maricopa County Animal Care and Control and Arizona Humane Society facilities from November 2014 through March 2015 (188). PROCEDURES Fresh fecal specimens were collected from all dogs; for AFR shelter dogs, specimens were collected within 72 hours after facility admission. Standard centrifugal flotation tests and an ELISA were performed to detect 5 common intestinal parasites (roundworms, hookworms, whipworms, Giardia spp, and Cystoisospora spp). Group comparisons were performed by means of the χ2 test and Rogan-Gladen prevalence estimate. RESULTS At least 1 of the 5 evaluated parasites was detected in 85 (45.2%) fecal specimens from AFR shelter dogs and 24 (13.7%) specimens from owned pet dogs. This prevalence differed significantly between the groups. Notably, the prevalence of Giardia spp in AFR shelter dogs (n = 76 [40.4%]) was higher than previously reported in the United States. CONCLUSIONS AND CLINICAL RELEVANCE The prevalence of the evaluated intestinal parasites, particularly of Giardia spp, in AFR shelter dogs was higher than expected. This information is important for veterinarians, animal shelter personnel, pet owners, human health-care providers, and public health officials to consider when devising effective interventions and risk communication efforts against potential zoonotic threats, particularly those relevant to the Phoenix metropolitan area.

Abstract
Gastrointestinal parasites, protozoa and helminths, remain a common important finding in dogs presented to veterinary medical practices. Moreover, dogs may play an active role in the transmission of enteric parasites to humans, given their cohabitation, making canine gastrointestinal parasitism an issue of major concern for public health. To get an overview of the current state of canine gastrointestinal parasites' prevalence in Greece, a total of 1036 faecal samples were collected from dogs either presented in veterinary clinics or in animal shelters. Samples were examined by a combined sedimentation-flotation technique. Possible risk factors (age, ownership status, co-existence with other animals, coinfection with other parasites) were assessed using binary regression models for each one of the most prevalent parasites. The overall gastrointestinal parasite prevalence in dogs' faecal samples was 39%. A total of 11 intestinal parasitic species were detected and up to five different parasites were isolated in the same faecal sample. Toxocara canis was the most prevalent parasite in the studied population, followed by Isospora spp., Giardia spp., Uncinaria spp., Trichuris vulpis, Ancylostoma spp., Toxascaris leonina, and Dipylidium caninum. Additionally, other genera (Taenia, Capillaria and Angiostrongylus) were also detected in very low percentages. Young, stray, living without other dogs, coinfected with T. vulpis or T. canis and free of Isospora spp. dogs were more likely to be infected by Giardia spp. Likewise, young, stray, coinfected with T. vulpis or T. canis but free of Giardia spp. dogs were more likely to be infected by Isospora spp. T. canis infections were more common in dogs coinfected with Isospora spp., Giardia spp., D. caninum, Τaenia spp., T. vulpis and T. leonina Finally, T. vulpis more often infected older dogs and dogs coinfected with Isospora spp., Giardia spp. and T. canis Consequently, the prevalence of parasitized dogs was high and the diversity of parasites found was notable, which calls for a greater awareness among veterinarians and pet owners. The proposed prediction models should be taken under consideration in diagnostic approach of clinical cases, as well as in planning sustainable antiparasitic strategies.

Abstract
This study aimed to update data on the prevalence of intestinal and lung parasitic infections in owned dogs and cats in Sardinia, Italy. Examinations on faecal samples from 619 dogs and 343 cats routinely referred to the Veterinary Teaching Hospital of the University of Sassari were performed between the years of 2011 and 2015. Individual faecal samples were analysed using the Wisconsin technique for copro-microscopic examination and the Baermann technique for the presence of lungworm larvae. Endoparasites were found in 34.9% and 43.4% of examined dogs and cats, respectively. Helminthic infections (21.2% in dogs and 32.6% in cats) occurred more frequently than protozoan infections (17.9% in dogs and 17.8% in cats). In both dogs and cats, the most common parasites were ascarids (12.1% and 15.7%), Cystoisospora spp. (10.2% and 10.8%), Giardia duodenalis (9.4% and 8.5%), and hookworms (7.9% and 5.5%). Evidence of bronchopulmonary nematode infections were found in 0.8% of examined dogs and in 15.8% of examined cats. Age was identified as a risk factor, with animals younger than 6months more frequently infected than older animals, while no significant association was observed for gender. This study demonstrated that endoparasites in owned dogs and cats of Sardinia have considerably high prevalence. Veterinary practitioners and pet owners should be more aware of these infections and should adopt more effective and standardized control practices.

Abstract
INTRODUCTION Dogs harbour zoonotic parasites that cause serious infections in humans, such as visceral larva migrans, ocular larva migrans, cystic echinococcosis, and alveolar echinococcosis. Studies on dogs' gastrointestinal parasites in different geographical locations are required to increase knowledge of the risk of canine zoonoses in human populations. MATERIAL AND METHODS The presence of parasites was examined in 450 faecal samples collected from eight zones of Zanjan province, northwest Iran from June to November 2015. The samples were examined using the sedimentation concentration method and modified Ziehl-Neelsen staining. RESULTS Gastrointestinal parasites were found in 86 (19.1%) faecal samples. Sarcocystis spp. (7.3%), Taenia/Echinococcus spp. (5.6%), Toxocara spp. (1.8%), and Cystoisospora spp. (1.6%) were the most common parasites observed. The other detected parasites consisted of Dicrocoelium dendriticum (0.7%), Eimeria spp. (0.7%), Cryptosporidium spp. (0.4%), Physaloptera spp. (0.4%), Giardia spp. (1.3%), and Spirocerca lupi (1.3%). The lowest parasite infection rates belonged to Trichuris vulpis and Acanthocephalans (0.2% each). CONCLUSION This study provides current information on the infection rates in dog populations in Zanjan Province. Furthermore, the study shows a high prevalence of gastrointestinal parasitic infections, including zoonotic ones and particularly Taenia/Echinococcus spp., potentially transmissible to humans and thus relevant to public health.

Abstract
Dogs have been bred since ancient times for companionship, hunting, protection, shepherding and other human activities. Some canine helminth parasites can cause significant clinical diseases in humans as Opisthorchis viverrini causing cholangiocarcinoma in Southeast Asian Countries. In this study, socio-cultural questionnaire, canine parasitological analysis, necropsy, parasite molecular confirmation and dog roaming data were evaluated in Savannakhet, Lao-PDR, a typical Mekong Basin area. Dog owners comprised 48.8% of the studied population, with 61.2% owning one dog, 25.1% 2 dogs, 8.5% 3 dogs and 1.8% owning more than 4 dogs. Data from GPS logger attached to dogs showed they walked from 1.4 to 13.3 km per day, covering an area of 3356.38m2 average, with a routine of accessing water sources. Thirteen zoonotic helminth species were observed. Causative agents of visceral and cutaneous larva migrans occurred in 44.1% and 70% of the samples respectively. Spirometra erinaceieuropaei was detected in 44.1% of samples. Importantly, O. viverrini was found in 8.8% of samples. Besides the known importance of dogs in the transmission of Ancylostoma spp., Toxocara spp. and S. erinaceieuropaei, the observed roaming pattern of dogs confirmed it as an important host perpetuating O. viverrini in endemic areas; their routine access to waterbodies may spread O. viverrini eggs in a favorable environment for the fluke development, facilitating the infection of fishes, and consequently infecting humans living in the same ecosystem. Therefore, parasitic NTDs control programs in humans should be done in parallel with parasite control in animals, especially dogs, in the Mekong River basin area.

Abstract
The prevalence of gastrointestinal helminth infections of dog in Enugu State, South Eastern Nigeria was studied retrospectively and prospectively. In the retrospective study, records of all diagnosed helminth infections of dogs brought to the University of Nigeria Veterinary Teaching Hospital, Nsukka from January, 2006 to September 2013 were collated and analyzed. The prospective study was carried out between October 2013 and July 2014 by examination of 263 faecal samples collected per rectum from dogs presented to a purposively selected Veterinary Clinics in Enugu metropolis and the Veterinary Teaching Hospital of the University of Nigeria, Nsukka. The results of the 8 year retrospective prevalence study gave an overall prevalence of 56.1% and Ancylostoma species as the most prevalent helminth in the study area (33.2%). Mixed infections with more than one helminth parasite species were recorded in 8.6% of the cases. Annual breakdown of the prevalence data showed that the highest prevalence was recorded in 2009. Breed and age of the dogs were found to significantly influence the prevalence. In the prospective study, an overall prevalence of 51.7% was obtained. Ancylostoma spp. was also found most often in the study area, with a prevalence rate of 33.6%. Mixed infections with more than one helminth parasite species were found in 16.3% of the cases. A strong association was obtained between prevalence and breed of the dogs and also between prevalence and season. Due to the zoonotic nature of most of the encountered parasites and the close association between children and dogs, routine deworming, proper management of dogs and adequate personal hygiene is therefore recommended.

Abstract
The understanding of the epidemiology of canine parasitic infections is necessary for an efficient control program to minimize the risk of zoonotic transmission. The objectives of this study were (1) to determine the prevalence of canine gastrointestinal helminths and protozoa in Basra province, Southern Iraq, and (2) to identify the association of epidemiological characteristics (age, breed, gender, and feed type) of dogs with the parasitic infections. A total of 93 fecal samples, collected in the period from December 2014 to June 2015, were examined macroscopically and microscopically for the presence of worm eggs and protozoal oocysts, using centrifugal flotation method. The overall prevalence of infected dogs was 77.4% (72/93). About 54.8% (51/93) dogs were infected with more than one genus of parasites. The prevalence of multiple infections with two, three, and four parasites was 30.1% (28/93), 22.6% (21/93), and 2.2% (2/93), respectively. The most frequently detected parasites were Toxocara canis (62.4%, 58/93), Physaloptera spp. (28%, 26/93), Alaria spp. (26.9%, 25/93), Trichuris vulpis (9.7%, 9/93), and Ancylostoma caninum (7.5%, 7/93). Isospora canis (6.5%, 6/93) and Giardia spp. (4.3%, 4/93) were the only protozoan parasites identified in this study. Toxocara canis infection was significantly associated with sex and age of the dogs (P < 0.05). Feeding type was significantly associated with the occurrence of T. canis (P < 0.0001), A. caninum (P < 0.03) and Alaria spp. (P < 0.02). The high prevalence of intestinal helminths in dog's population suggesting the need for more efficient control measures. The high prevalence of T. canis, T. vulpis, A. caninum and Giardia spp. suggested that dogs could play an active role in the transmission of zoonotic parasites in this area of Iraq. Educating the dog owners and increasing their health awareness should be considered in the control program. The results of the present study provide relevant "base-line" data for assessing the effectiveness of future control strategies against canine parasitic infections.

Abstract
Abstract Occurrences of gastrointestinal parasites were assessed in fecal samples from 3,099 dogs in the metropolitan region of São Paulo, SP, that were treated at the Veterinary Hospital of the University of São Paulo Veterinary School. The samples were analyzed using the flotation and centrifugal sedimentation methods. The results were compared with those from previous studies (at different times). The frequency of each parasite was correlated with the dogs’ ages, breeds and gender, as well as the occurrences of diarrhea and the use of anthelmintics, by means of the chi-square or Fisher exact test. Partitioned chi-square tests were used to compare occurrences of each parasite and the times analyzed. Out of the total number of samples, 20.5% were positive and 16.1% (102/635) of these presented more than one genus of parasites. Ancylostoma spp. (7.1%) and Giardia spp. (5.5%) were the most frequent helminths and protozoa, respectively. Ancylostoma spp. was associated (p<0.05) with age (over one year), mixed breeds, sex (male) and no use of anthelmintics. Dogs under one year and mixed breeds were associated with occurrences of Toxocara canis; and younger dogs with Giardia spp., Cryptosporidium spp. and Cystoisospora spp. Giardia spp. were also associated with dogs with a defined breed (p<0.05). All the parasites analyzed presented lower incidence in the last period analyzed than in the previous periods.

Abstract
Resumo O gênero Cryptosporidium é composto por protozoários com grande capacidade de reprodução e disseminação. Sua transmissão pode ocorrer indiretamente pela ingestão de água e alimentos contaminados com oocistos viáveis ou diretamente entre animais, entre humanos ou entre animais e humanos. Em diversas partes do mundo, animais de companhia tem sido citados como fontes potenciais de infecção por Cryptosporidium spp. O presente estudo teve como objetivo avaliar a ocorrência da infecção por Cryptosporidium spp. em cães domiciliados na cidade do Recife, estado de Pernambuco, Brasil, bem como a associação da infecção com dados epidemiológicos e sanitários. Foram analisadas 97 amostras de fezes de caninos domiciliados, utilizando-se as técnicas de centrífugo-sedimentação em formol-éter com posterior coloração pelo método de Kinyoun. A análise estatística foi realizada por meio dos testes Qui-quadrado de Pearson e Exato de Fisher, com nível de significância de 5,0%. Detectou-se positividade de 31,9% (31/97), tratando-se do primeiro registro de ocorrência da infecção por Cryptosporidium spp. na espécie canina no nordeste brasileiro, verificando-se associação significativa entre a taxa de infecção e a assistência médica veterinária, vacinação recebida e o tipo de ambiente de criação dos cães.

Abstract
The objective of this study was to determine the prevalence and risk factors for the occurrence of endoparasitosis in dogs and cats in Espírito Santo, Brazil. For the study, 345 dogs and 160 cats were examined. Faecal samples from the animals were collected, and owners were interviewed about their handling of their animals. For the diagnosis of the infections, the Willis-Molley, simple centrifugal flotation and formalin-ether sedimentation techniques were performed. The data found in the tests were tabulated and analysed with a chi-square test (p <0.05), and calculation of odds ratios (OR) with confidence intervals of 95% were then performed to determine the association between the variables and the outcome of stool examinations. The prevalence of parasites was 59% for dogs and 54% for cats. The genus Ancylostoma was the most prevalent (45%). Supplying filtered water, not feeding raw foods, standardisation of a defecation site and cleaning up the faeces reduced the chances of developing intestinal parasites. An increased frequency of deworming was also shown to be a protective factor; specifically animals which received anthelmintic more than once a year had a lower predisposition for intestinal parasites.

Abstract
Ivermectin is one of the most effective and widely used antiparasitic agents ever discovered because of its broad spectrum activity against nematodes and arthropods. Therefore, the study was conducted to determine the comparative anthelmintic efficacy of ivermectin by giving through oral and subcutaneous routes in clinically infected dogs and also to check the prevalence of gastrointestinal nematode in dogs in Bhubaneswar, Odisha. Total 154 dogs with clinical signs of gastroenteritis were examined for the presence of nematodal ova in their faecal sample and 64 were found positive (41.56 %). The screened dogs were divided in to two groups (n = 10 each), first group of animals were treated with ivermectin @ 0.5 mg/kg body weight by subcutaneous route and the second group with same dose of ivermectin through oral route. Efficacy of ivermectin was evaluated based on egg per gram (EPG), haematological and biochemical parameters. It is concluded that, Prevalence of gastrointestinal nematodes are high in dogs in the climatic condition of Bhubaneswar, Odisha. Ivermectin was found effective when administered through either of the routes. Haemato-biochemical parameters were restored after administration of ivermectin and also significant reduction in EPG was found in dogs treated with ivermectin by both the routes, but no significant difference was observed in EPG between oral and subcutaneous treated dogs in various intervals of study.

Abstract
The present study was conducted to determine the prevalence of helminth eggs excreted in the faeces of stray cats, dogs and in soil samples. A total of 505 fresh samples of faeces (from 227 dogs and 152 cats) and soil were collected. The egg stage was detected via microscopy after the application of formalin–ether concentration technique. Genomic DNA was extracted from the samples containing hookworm eggs and used for further identification to the species level using real-time polymerase chain reaction coupled with high resolution melting analysis. Microscopic observation showed that the overall prevalence of helminth eggs among stray cats and dogs was 75.7% (95% CI = 71.2%–79.9%), in which 87.7% of dogs and 57.9% of cats were infected with at least one parasite genus. Five genera of heliminth eggs were detected in the faecal samples, including hookworms (46.4%), Toxocara (11.1%), Trichuris (8.4%), Spirometra (7.4%) and Ascaris (2.4%). The prevalence of helminth infections among stray dogs was significantly higher than that among stray cats (p < 0.001). Only three genera of helminths were detected in soil samples with the prevalence of 23% (95% CI = 15.1%–31%), consisting of hookworms (16.6%), Ascaris (4%) and Toxocara (2.4%). The molecular identification of hookworm species revealed that Ancylostoma ceylanicum was dominant in both faecal and soil samples. The dog hookworm, Ancylostoma caninum, was also detected among cats, which is the first such occurrence reported in Malaysia till date. This finding indicated that there was a cross-infection of A. caninum between stray cats and dogs because of their coexistent within human communities. Taken together, these data suggest the potential role of stray cats and dogs as being the main sources of environmental contamination as well as for human infections.

Abstract
An epidemiological study was conducted to determine the prevalence of helminthic parasites of domestic dogs using stool samples in north of Iran in 2013. Stool samples (n = 100) were collected from domestic dogs of different ages and genders. Different techniques including wet smear, formalin-ether sedimentation method and flotation technique in saturated zinc chloride solution were performed on collected stools to detect eggs and larval stage of helminthes parasites. The overall prevalence of helminthic parasites of examined stools of dogs was 57 %. The examined domestic dogs harbored eggs of eight species of helminthes including: Taenia spp., Diyplidium caninum, Toxocara canis, Toxascaris leonina, Capillaria aerophila, Mesostesphanus spp. and Trichuris volpis. T. canis and T. volpis were the most and least prevalent eggs, respectively. No significant statistical differences were observed between infection by helminthic parasites and both gender and age of the dogs (P > 0.05). Considering high level of helminthic infection in the stool of examined domestic dogs, a contiguous educational program to increase awareness of dog owners and an effective anti-parasite control programmed is highly recommended in order to reduce the danger of zoonotic diseases in north of Iran. This is the first report of C. aerophila and Mesostesphanus spp. from dog in Iran.

Abstract
Dogs play many roles and their presence within people’s houses has increased. In rural settings dog faeces are not removed from the streets, representing an environmental pollution factor. Our aim was to evaluate the occurrence of environmental contamination with zoonotic intestinal parasites of three groups of dogs in Ponte de Lima, Portugal, with a particular emphasis on Echinococcus granulosus. We collected 592 dog faecal samples from the environment, farm and hunting dogs. Qualitative flotation coprological analysis was performed and the frequency in the positive samples ranged between 57.44% and 81.19% in different groups. We isolated up to four different parasites in one sample and detected seven intestinal parasitic species, genera or families overall. Ancylostomatidae was the most prevalent parasite, followed by Trichuris spp., Toxocara spp., Isospora spp., Dipylidium caninum, Taeniidae and Toxascaris leonina. Taeniidae eggs were analyzed with the PCR technique and revealed not to be from Echinococcus. The parasite prevalence and the diversity of zoonotic parasites found were high, which calls for a greater awareness of the problem among the population, especially hunters. Promoting research at the local level is important to plan control strategies. Health education should be developed with regard to farmers and hunters, and a closer collaboration between researchers, practitioners and public health authorities is needed.

Abstract
A total of 246 faecal/scat samples of the dogs were screened by direct and floatation concentration technique to study the gastrointestinal (GI) tract parasitism in dogs of Palampur, Himachal Pradesh, India. Detailed coprological examination targeting different seasons, age groups and living styles of the dogs revealed an overall 28.04 % of GI parasitism with highest prevalence in summer season (37.87 %). Stray dogs harbored 47.29 % GI parasites in comparison to 19.19 % of pet dogs. Highest prevalence of GI parasitism was observed in the pups, below 3 months of age (39.13 %), followed by the dogs with the age ranging from 3 months to 1 year (26.38 %) and lowest in dogs of the age ranging from 1 to 3 years (6.77 %). Amongst all the parasites, Toxocara canis (44.93 %) infection was highest, followed by Dipylidium caninum (17.39 %) and hookworms (15.94 %).

Abstract
This research was conducted to determine the prevalence of gastrointestinal helminths in stray dogs in the northeast of Iran, with special attention to those parasites that can be transmitted to human. In this experiment, a total of 72 adult and 18 juvenile stray dogs were collected and necropsied for the presence of helminth parasites from October 2011 to August 2012. The overall prevalence of gastrointestinal helminths was 86 % (95 % CI: 79.2-92.8 %). The observed helminths of the gastrointestinal tract were listed as follows: Toxocara canis (29 %), Toxascaris leonina (7 %), Ancylostoma caninum (2 %), Taenia hydatigena (43 %), Dipylidium caninum (39 %), Echinococcus granulosus (38 %), Mesocestoides lineatus (16 %), Taenia multiceps (11 %), Taenia ovis (3 %). There were no significant differences for the prevalence of gastrointestinal helminths between female (83.6 %) and male (89.7 %) and between young (89 %) and adult (72.2 %) animals. However, the prevalence of E. granulosus, T. hydatigena and D. caninum showed an increasing trend with increasing host age, significantly. Based on our data, it is important to point out the presence of zoonotic agents, namely E. granulosus and T. canis in stray dogs in the investigated area. Due to its impact on public health, appropriate control measures should be taken and it is recommended to determine the most appropriate preventive methods.

Abstract
Prevalence and risk factors of intestinal and lung parasites were investigated in 239 owned dogs and 81 owned cats from central Italy. In 36 dogs and 20 cats found infected by nematodes, pre and post-treatment faecal egg count (FEC) was also evaluated. About 31% of dogs and about 35% of cats resulted positive for at least one intestinal or lung parasitic species. Helminthic, intestinal and zoonotic infections resulted prevalent in examined animals. Examined dogs resulted infected by Toxocara canis (13.0%), Toxascaris leonina (1.7%), Trichuris vulpis (3.3%), Ancylostoma caninum (2.0%), Uncinaria stenocephala (1.25%), Strongyloides stercoralis (0.8%), Angiostrongylus vasorum (0.4%), Dipylidium caninum (1.25%), Taeniidae eggs (0.4%), Giardia duodenalis (3.8%), and Cystoisospora (Isospora) spp. (7.5%). Examined cats were infected by Toxocara cati (22.2%), Capillaria aerophila (1.2%), Ancylostoma tubaeformae (1.2%), U. stenocephala (3.7%), Aelurostrongylus abstrusus (1.2%), Mesocestoides sp. (1.2%), D. caninum (1.2%), G. duodenalis (1.2%) and Cystoisospora spp. (4.5%). The presence of clinical signs and the young age (less than 6 months) were identified as risk factors by univariate and multivariate statistical analysis. In 63.9% treated dogs and in 80.0% treated cats, percentages of post-treatment FEC reduction higher than 90% were found. Results obtained in this study are discussed.

Abstract
The objective of this study was to determine the prevalence rate of helminthic parasites in stray dogs' population especially zoonotic infections and to identify potential risk factors in the different areas of Sari city in Caspian area, north of Iran. During the period from April to September 2007, 50 stray dogs were collected from urban areas of Sari city. Recovered parasites were fixed in alcohol and stained by carmine then observed by microscope. The taxonomic study was carried out by measuring different parts of the body of helminthes and statistical tests were performed using the Chi-square test. A total of 27 adult and 23 juvenile stray dogs were collected and the overall prevalence rate of infection was 90%. The three most common helminthes were Toxocara canis (60%), Ancylostoma caninum (46%) and Dipylidium caninum (36%). Other parasites were Uncinaria stenocephala (12%), Taenia hydatigena (6%), Spirocerca lupi (6%), Dirofilaria immitis (6%), Toxascaris leonina (2%), Rictularia sp. (2%), Taenia ovis (2%) and Taenia taeniformis (2%). Five species of zoonotic helminthes recovered were T. canis, A. caninum, U. stenocephala, D. caninum and D. immitis. Hookworm infections (58%) were more common significantly in the young stray dogs (p < 0.01). In regard to prevalence ofA. caninum, T. canis and U. stenocephala, there was significant difference between juvenile and adult dogs (p < 0.05). The results highlight the potential role of stray dogs for transmission of helminthic parasites particularly zoonotic parasites that are a significant risk to human health.
