Abstract
BACKGROUND Dogs, as well as a wide variety of other warm-blooded animals, act as intermediate host of Toxoplasma gondii. In dogs, most cases of toxoplasmosis are subclinical, although clinical disease has been sporadically reported. Beyond its role in diagnostic pathways, seropositivity also functions as a reflection of the parasite's spread within the dog's living environment. The aim of the present study was to evaluate the possible risk factor associated with seropositivity to T. gondii in dogs in Central-Northern Italy, analysing 120 dogs sera for the presence of IgG antibodies by indirect fluorescence antibody test (IFAT). RESULTS The population examined was composed of 54.2% hunting dogs, 24.2% companion dogs, 14.2% truffle dogs and 7.5% watchdogs. Thirty-four (29.2%) dogs tested positive for T. gondii IgG, with titres ranging from 1:40 to 1:1280. Seroprevalence and antibodies titres were not related to dog gender, age or function. The logistic regression and ordered logistic regression results indicated that seroprevalence, and antibody titres were significantly higher in dogs cohabiting with cats, exhibiting coprophagy habits, and living constantly outdoors. Notably, the lifestyle factor showed the highest odds-ratios in the study: dogs living constantly outdoors were found to be at approximately 5 times greater risk of testing positive and having higher antibody titres compared to dogs living both indoors and outdoors. CONCLUSION Both logistic and ordered logistic regression results support the key role of living with cats, engaging in coprophagy behaviours, and maintaining an outdoor lifestyle in increasing the risk of T. gondii infection in dogs. These identified risk factors collectively suggest that both ingesting oocysts, as observed through cat cohabitation and coprophagy, and engaging in predatory behaviours, as possible for outdoor living dogs, are indicating likely sources of T. gondii infection in this host species.

Abstract
Humans and dogs commonly share the same domestic environment. Europe, and Italy specifically, have a substantial and growing dog population. Potentially zoonotic parasites may be harbored even by dogs receiving regular veterinary care. Thus, transmission of zoonotic or potentially zoonotic parasites to owners and their families should not be underestimated. Frequently, endoparasite infections occur as a subclinical infection and clinicopathological alterations have been documented including anemia, hypoalbuminemia, and eosinophilia. The aim of this large retrospective secondary data study was to analyze coprological endoparasite results and putative risk factors obtained from owned dogs, through a 9-year-period (2011-2019). Possible associations between diagnosed endoparasites and sex, age, seasonality, and year of examination were evaluated. Additionally, parasitological diagnoses were combined to complete blood count parameters and biochemical profiles, when available, to check for any possible hematological alteration from parasitism. A total of 1,972 dogs were evaluated for endoparasites using common fecal diagnostic tests over a 9-year period. The overall proportion of endoparasite-positive animals was 10%. The most common endoparasites detected were Cystoisospora spp. (3%), Toxocara canis (2.8%), Giardia duodenalis (1.6%), and Trichuris vulpis (1.2%). Of these parasites detected, Toxocara poses the greatest zoonotic risk, while Giardia species are considered to have a low potential to be zoonotic. There was no significant diagnostic trend across the years through the study period. Dogs were more frequently diagnosed endoparasite-positive when young and during cold seasons compared to the baselines of mature dogs and warm seasons. The clinicopathological profiles indicated that parasitized dogs had mild hematological alterations. The frequency of detected potentially zoonotic endoparasites in this study highlights that the risk should not be underestimated. Parasitic infection was found to be mostly dependent on age and season. Having this information may help clinicians to develop anthelmintic protocols to reduce the risk of transmission.

Abstract
Parasites and parasitologists have always lived together in good and bad luck in a sort of forced marriage. In recent times bad luck certainly prevailed, because of increasing man-made emergencies such as wars, chemical disasters, but also because of natural disasters, amplified by climate change, that condition more and more parasite–host equilibrium. The symposium at the National Congress of the Italian Society for Parasitology, was a first occasion for Italian parasitologists to reason about ‘disaster parasitology’ and researchers’ responsibilities. Extreme weather events and their impacts on parasites’ epidemiology are illustrated, comparing disasters that recently occurred in Italy with literature data. In particular, the Sardinian Island was hit subsequently by fires and floods exacerbating the effects on ecosystems and parasite–host-relationships. Examples of Cryptosporidium outbreaks in man and Fasciola hepatica infections in various hosts after heavy rains are reviewed and effects of droughts on pasture borne parasites, such as gastro-intestinal nematodes of ruminants are discussed. Heavy rains may also cause dissemination of toxic substances released accidentally from chemical plants as happened e.g. in Milan province (IT) after the dioxin hazard. The overlapping effects of strictly man-made disasters with climate change dependent extreme weather events is further challenging the understanding of what are the consequences of disasters on ecosystems and parasite epidemiology.GIS applications combined with AI programs may help to face the complex challenges, allowing the collection and analysis of spatial/temporal data at whatever level desired. Examples illustrated in the article suggest their employment also in a more systematic, prevention-oriented manner.

Abstract
Livestock breeding is one of the main agricultural activities in Tanzania, recognized as one of the African countries with the greatest livestock resources. Cattle is the most widely bred animal species, especially with traditional farming methods such as pastoralism and agro-pastoralism. Slaughtering takes place mainly in rural slaughter slabs and municipal slaughterhouses, and according to local legislation it must be supervised by Official Veterinarians, who report any organs to be discarded and, after stamping the carcass, authorize its free consumption. Since the Ruvuma region lacks data on cattle diseases, the aim of this study was to collect information at Songea slaughterhouse, with particular attention to conditions of parasitic aetiology and potential zoonotic interest, deepening inspective diagnoses by means of parasitological and histological investigations on tissue samples. Overall, the slaughter data of 614 animals are reported. In most cases slaughtered cattle belonged to local breeds and came from the Mbeya region. Fasciolosis (diagnosed in 44.6% of animals) was the most frequent condition, followed by respiratory diseases (24.4%), aortic onchocerciasis (6.5%), hydatidosis (5.5%) and bovine cysticercosis (3.4%). Laboratory analysis identified Fasciola gigantica as the species involved in hepatic distomatosis in this area. Cases macroscopically ascribed to cysticercosis turned out to be a muscular form of onchocerciasis (by Onchocerca dukei), a neglected and unrecognised parasitic disease in Tanzania, questioning the real frequence of a zoonosis that causes primarily major economic losses. Pulmonary cysts, referred as hydatidosis at visual inspection, were histologically identified as haemal nodes, lymphoid organs common in ruminants, but described in cattle lungs for the first time in the present paper. Slaughterhouse is an important epidemiological observatory, especially for neglected parasitoses. The possibility of having basic laboratory diagnostics as an aid to visual inspection can ensure greater efficiency of veterinary services in the control of important livestock diseases and zoonoses, in the frame of a One Health perspective.

Abstract
Despite being a parasitic disease known since ancient times, some epidemiological aspects of cystic echinococcosis (CE) remain unclear. Many studies describe its prevalence and genotyping in populations of domestic animals and livestock, but data regarding wildlife are often scarce and incomplete. The available literature suggests that CE has never been reported in African rhinos. Considering the fragile conservation status of these species due to continued poaching, this study tries to clarify some neglected epidemiological aspects. In February 2020, an adult female of the Southern white rhinoceros, Ceratotherium simum simum (Burchell, 1817), was killed by poachers. The subsequent necropsy performed by the state veterinary team revealed the presence of seven cysts within the pulmonary tissue (four cysts in the right medio-caudal lobe and three cysts in the left medio-caudal lobe) with a diameter of between 1.5 and 2.3 cm. Given the state of decomposition of the carcass, only two of these were suitable for microscopic examination. Specimens were examined under 10x and 40x microscopic magnification for the confirmation of fertility of the cysts, based on the presence of numerous protoscoleces in different stages of maturation. A histopathological examination was also performed to describe the relationship between parasite and host tissue reaction. Cyst samples were subjected to PCR. The primers successfully amplified the expected fragments of the cox-1 and the nad-1 gene from the isolated genomic DNA, revealing high sequence identity with published sequences of Echinococcus equinus Williams & Sweatman, 1963 isolate G4 and E. equinus isolate SLG5-G4.

Abstract
Pulmonary capillariasis is a parasitic disease caused by the nematode Eucoleus aerophilus which affects wild and domestic carnivores. Currently, there are no anthelmintics approved for use in the treatment of dogs infected with E. aerophilus. The use of several anthelmintics has been reported in a few case reports and field efficacy studies in cats; much less is known on the treatment of dogs infected with E. aerophilus. The paper describes a case of a 4-month-old, mixed breed intact male referred to the Veterinary Teaching Hospital (VTH) of the Department of Veterinary Medical Science of the University of Bologna for a routine vaccination and tested positive for E. aerophilus. The dog has not been responding to three different administered treatments, such as moxidectin, fenbendazole, and milbemycin oxime. Eighteen months after the first fecal examination, owner has brought in the dog for a routine visit; a coprological examination was requested and performed resulting negative for parasites. Veterinary practitioners, parasitologists, diagnostic laboratories, and dog owners need to be aware of the increased danger of possible treatment failure when attempting to control parasitic infections for which there are no approved anthelmintics with established efficacies available for use.

Abstract
Several developments have been recently achieved to understand pet-dog parasites and their relationship with hosts; however, parasites' presence and distribution in shepherd-dog have been mainly neglected; this knowledge gap is of critical sanitary importance, as shepherd-dogs could harbor zoonotic helminths including Echinococcus granulosus sensu lato. The related human disease, cystic echinococcosis, is a worldwide neglected disease, with high endemicity in the Mediterranean Basin. To evaluate the presence of E. granulosus and other parasites, a sheep-dog population from the province of Grosseto (Tuscany, Italy) has been investigated. Overall, 648 dog fecal samples obtained from 50 modern sheep farms, having a total of 216 dogs, were collected. Specimens were analyzed using a standardized centrifugal flotation method (specific gravity = 1.3). Taeniid eggs detected were further isolated using a sieving/flotation technique. DNA was isolated from eggs for PCR and sequence analyses for species identification (gene target: 12S rRNA and nad1). Thirty-nine (78%) farms tested positive for at least one parasite species or genus. The most represented intestinal helminths were Toxocara spp. in 64% of farms, followed by Ancylostomatidae (58%), Trichuris vulpis (50%), Capillaria spp. (34%), and taeniids (32%). Sequence analyses confirmed the presence of Taenia hydatigena in seven farms, Taenia (syn. Multiceps) multiceps in five farms, and T. pisiformis in one farm. No DNA was extracted from four previously taeniid egg-positive farms. No amplification of amplicon corresponding to E. granulosus was achieved in the investigated farms. Although not entirely expected, Spearman's test showed a positive correlation between flock size and the number of dogs per farm (ρ = 0.588, P < 0.001). The quantitative analysis reported that the home slaughter practice was affected neither by the flock size nor by the number of dogs per farm. The probability to diagnose farms positive for taeniids had been increased by about 35% for each dog unit increase [odds ratio (OR) = 1.35, P = 0.012]. In conclusion, the wide distribution of T. hydatigena and T. multiceps detected in the present study clearly reveals that dogs have still access to raw offal, a major risk for the transmission of E. granulosus. Home slaughtering is an unavoidable practice, and more efforts must be undertaken by the public health system to prevent and control potential zoonotic taeniids.

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
Crenosoma vulpis, the fox lungworm, is a nematode parasite of wild and domestic canids belonging to the super-family Metastrongyloidea. A survey of infection was carried out examining 88 red foxes (Vulpes vulpes) obtained during the regular hunting season (2014-2015) from the Emilia-Romagna region of Italy. Carcasses were stored frozen (- 21 °C) prior to necropsy. Lungs were examined for the presence of adult worms by dissection of the trachea, bronchi, and bronchioles, and then the lung tissue was examined for first-stage larvae (L1) by the Baermann method. No adult stages were detected, but L1, identified based on morphology as Crenosoma vulpis, were recovered from 28.4% (25/88) of the fox lungs. No significant differences in infection were found based on sex or geographical distribution. A brief review on C. vulpis report in red foxes in Italy and other European countries was also carried out.

Abstract
INTRODUCTION Cystic Echinococcosis (CE) is one of the most widespread zoonosis of veterinary and medical importance still constituting a sanitary, economic and socio-cultural problem in Italy. METHODOLOGY The aim of this study was to update epidemiological data on cattle CE in Italy. Data on CE positivity of 5,336 cattle were acquired from abattoir registers between January 2009 and July 2010. Morphobiological characterization of hydatids was performed by direct examination of liver and lungs of 1,664 animals butchered in the same slaughterhouses in 2010. Strain typing of parasites was carried out through the amplification and sequencing of nd1 and cox1 mitochondrial genes. RESULTS Overall CE prevalence was of 8.1% (430/5,336). Parasitological examination of hydatids showed an overall prevalence of 8.6% with a fertility rate of 0.7% (12/1,664). Regarding localization, hydatids were found in 8% of the livers and in 7.6% of the lungs, respectively. Among positive animals, higher prevalence was observed in the liver (93%) compared to lungs (88.1%) (p > 0.05). CONCLUSION The economic loss due to organs condemnation related to CE in cattle amounted to almost € 24,000 per year in the examined abattoir during 2010. Sequence analysis showed the presence of G1 (sheep strain) or Echinococcus granulosus sensu strictu in all examined samples. The G1 confirmed, once more, its possible development into several intermediate hosts such as cattle, especially in areas like southern Italy and Sardinia where the lifecycle of the parasite is still to date carried on by sheep and dogs.

Abstract
Human leishmaniasis is an emerging problem in Italy and is on the increase in the Emilia-Romagna region, northeastern part of the country. Nevertheless, studies dealing with the molecular characterization of Leishmania spp. circulating in these areas are limited. In the present work, we explored the genetic polymorphism of Leishmania isolates from 28 cases of canine leishmaniasis and three cases of human visceral leishmaniasis (VL), which occurred in 2013-2014 in the Emilia-Romagna region. The characterization was carried out in comparison with nine human isolates of Leishmania from other VL endemic Italian regions and two reference strains. Nucleic acid from 31 Leishmania-positive phlebotomine sandfly pools, sampled in 2012-2013 in the Emilia-Romagna region, were also evaluated. DNA amplification and sequencing of the ribosomal internal transcribed spacer-1 and of a repetitive nuclear region on chromosome 31 were carried out for genotyping. Two size polymorphic targets were also analyzed by PCR, the cpb E/F-gene and the k26-gene. Altogether, the analysis showed the circulation of different Leishmania infantum genotypes in the Emilia-Romagna region: two genotypes found in dogs from public kennels were similar to VL isolates from other Italian regions, whereas a third genotype was detected in VL cases of the Emilia-Romagna region and in all but one of the sandfly pools. The combined molecular tools applied in this study can constitute a helpful support for parasite tracking (e.g., in outbreak investigations) and for a better understanding of the epidemiological evolution of leishmaniasis in northeastern Italy.

Abstract
After centuries of massive decline, the recovery of the wolf (Canis lupus italicus) in Italy is a typical conservation success story. To learn more about the possible role of parasites in the wolves' individual and population health and conservation we used non-invasive molecular approaches on fecal samples to identify individual wolves, pack membership, and the taeniids present, some of which are zoonotic. A total of 130 specimens belonging to 54 wolves from eight packs were collected and examined. Taeniid eggs were isolated using a sieving/flotation technique, and the species level was identified by PCR (gene target: 12S rRNA and nad1). Taeniid prevalence was 40.7% for Taenia hydatigena, 22.2% for T. krabbei, 1.8% for T. polyachanta and 5.5% for Echinococcus granulosus. The prevalence of E. granulosus is discussed. Our results show that the taeniid fauna found in wolves from the Foreste Casentinesi National Park is comparable to that described for other domestic and wild Italian canids and provides insights into the wolves’ diet and their relationship with the environment. Non-invasive techniques were used to identify individual wolves and their taeniids. The taeniids detected could be linked to individual wolves and to packs. The taeniids detected provided information on the wolves' diet and on zoonotic risk.

Abstract
Multilocus enzyme electrophoresis is the tool most frequently used to classify Leishmania spp., although it is time consuming and, sometimes, a not enough discriminative method. In the present study a kinetoplast DNA polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to characterize 16 zymodeme MON-1 Leishmania infantum strains: 15 were from dogs housed in public kennels of 7 geographical areas in the Emilia-Romagna region, Northern Italy, 1 was the L. infantum reference strain MHOM/TN/1980/IPT1. Six enzymatic patterns were observed. Kinetoplast DNA RFLP-PCR confirmed to have a good discriminatory power within the same zymodeme and proved to be useful for comparing few strains or discriminating between relapse and reinfection in the same host. We therefore recommend it use for discriminating between relapse and reinfection in the same host rather than supporting large-scale epidemiological studies.

Abstract
Background Nematode parasites of the genus Trichinella are important foodborne pathogens transmitted by ingestion of striated muscles harbouring infective larvae. Wild carnivorous and omnivorous animals are the most important reservoirs of these parasites. Hunting activities play an important role in Trichinella spp. epidemiology. The aim of the present work was to assess if serological detection of anti-Trichinella IgG in hunting dogs can be a tool to indirectly monitor Trichinella spp. infections in wildlife. Methods An ELISA and a Western blot (Wb) were developed and validated. To validate the assays, serum samples were collected from 598 dogs considered to be Trichinella-free, 15 naturally infected dogs, and six experimentally infected foxes. Sera were tested by ELISA with Trichinella spiralis excretory/secretory antigens. The diagnostic sensitivity and specificity of ELISA were 100 % (95 % CI: 83.89–100 %) and 95.65 % (95 % CI: 93.69–97.14 %), respectively. Sera from Trichinella-infected dogs/foxes tested by Wb showed a three-band pattern ranging from 48 to 72 kDa. Since the prevalence of Toxocara canis is very high in dogs, the specificity of the ELISA and Wb was further assessed by testing sera for anti-T. canis IgG using T. canis excretory/secretory antigens. No cross-reactivity was observed. To evaluate the test’s reliability in the field, serum samples were collected from wild boar hunting dogs from Central Italy where Trichinella britovi was circulating among wildlife. Results Out of 384 hunting dog sera, 189 (49.2 %) tested positive by ELISA and of these, 56 (29.6 %) tested positive by Wb, showing an overall prevalence of 14.6 % (56/384) in the wild boar hunting dog population of the investigated area. The serological prevalence in hunting dogs was significantly (P < 0.001) associated with the hunting district’s altitude. This is in agreement with previous investigations, which had shown that the prevalence of T. britovi in wildlife was higher in mountainous areas than in lowland areas of Italy. Conclusion The results suggest that the circulation of Trichinella spp. among wildlife can be monitored by testing sera from hunting dogs, which could act as sentinel animals of Trichinella spp. circulation in wildlife.

Abstract
The respiratory tracts of 57 wild boars (Sus scrofa L. 1758) hunted in central Italy during the 2011/2012 hunting season were examined to detect the presence of lung worms. Fifty-five out of 57 animals (96,5%) were positive. Five species of Metastrongylus were detected and their prevalence was as follows: Metastrongylus asymmetricus Noda, 1973 (91.2%), Metastrongylus confusus Jansen, 1964 and Metastrongylus salmi Gedoelst, 1923 (87.7%), Metastrongylus apri Gmelin, 1790 (80.7%), Metastrongylus pudendotectus Vostokov, 1905 (70.2%). In most cases multi-species infection was observed. The highest parasite load was found in young animals (<1 year old). The Metastrongylus genus sex ratio (M/F) had a range from 1:4.8 to 1:1.5 in favor of females. The Simpson and Shannon-Wiener indices showed a moderate uniformity in parasite community composition. The Fager index highlighted a high degree of affinity among all pairs of selected parasites. The whole parasite population showed an aggregate distribution. Our findings confirm that these parasites are widespread in the wild boar population. The establishment of outdoor domestic pig farming in the same area of the game preserve could pose the risk of infection to domestic animals. Further studies will be needed to understand the factors involved in the presence and prevalence of the intermediate host as well as the population dynamics of Metastrongylus spp.

Abstract
The Republic of San Marino is an autonomous State that, in view of its geographical and environmental features, can be considered a part of the Northern Italian territory, where the canine leishmaniasis (CanL) is endemic. In the past, a CanL focus in the Republic's kennel was described. As a consequence of this epidemiological situation, a surveillance program was carried-out covering a 6-year period (2006-2012). A total of 1,094 sera were collected from 420 kennel dogs and examined for antibodies to Leishmania infantum by the indirect fluorescent antibody test (IFAT). Eighty-eight (21%) dogs resulted IFAT positive (antibody titre ≥1/40). The overall seroprevalence increased in the first 4 years (2006-2010), going from 5.5% to 26.8% and then decreased in the 2 following years going to 17.9%(2011) and 3.9% (2012). The cumulative incidence constantly increased from 0.6% to 2.6%. This trend could be attributed to a changed infection pressure due to the dog turnover in the kennels. According to the observed incidence values, the CanL focus seems to be stable, supported by autochthonous transmission, new case introduction and Leishmania spp. circulation in owned dogs in the same area.

Abstract
The increasing reports of Troglostrongylus brevior lungworm in domestic cats from Italy and Spain raised questions on its factual distribution and on the role wildcats play as reservoirs of these parasites. Carcasses of 21 wildcats were collected in natural parks of southern Italy (i.e., Catania, Sicily n=5 and Matera, Basilicata n=16) and biometrically and genetically identified as Felis silvestris silvestris, but two as hybrids. Troglostrongylus brevior and Eucoleus aerophilus lungworms were found in 15 (71.4%) and 7 (33.3%) individuals, respectively, being five (23.8%) co-infected by the two species. Both lungworms showed an aggregated distribution in the host population, assessed by k-index (i.e., 0.69 for T. brevior and 0.42 for E. aerophilus). Although no statistical significant difference was recorded among age, gender and geographical location of wildcats, a larger rate of infection by T. brevior was assessed in yearlings (85.7%) than adults (64.3%). This is the first epidemiological study reporting T. brevior infection in the European wildcat and discusses the potential threat this may represent for the conservation of this endangered species of felids. In addition, given the large frequency of lungworm infection herein recorded, the role of wildcats as reservoir hosts of these parasites to domestic cats is discussed.

Abstract
An epidemiological survey on canine leishmaniasis (CanL) was performed during a 3-year period (2007-2009) in a public kennel of the Bologna province. The presence of the disease was shown in the canine population for the first time in 2007 by indirect fluorescent antibody test (IFAT). The parasite circulation was confirmed also by direct diagnostic tools, as PCR, cytology and cultural method, performed on different bioptic materials. The parasite was isolated and identified as Leishmania infantum zymodeme MON 1. The serological monitoring was performed also in 2008 and 2009 on animals that previously showed negative or uncertain results. The incidence values calculated by significant seroconversions in IFAT titre ≥ 1/160, ranged between 4.9% and 6.6%, indicating a stable focus of leishmaniasis. The entomological survey, performed by sticky and CO(2)-baited traps in 2008, showed the presence of the vector Phlebotomus perfiliewi. This study allowed us to identify a stable focus of CanL in an area that was not considered eco-compatible with the presence of the vector and infection. Our results confirm the northward spread of CanL towards areas not previously affected by autochthonous foci.

Abstract
Between December 2005 and November 2006, a survey on coccidiosis of wild and captive mouflons living in the Orecchiella Natural Reserve (Tuscany, Italy) was performed on faecal samples collected approximately every two months. A total of 96 samples were collected, 55 of which from wild mouflons and 41 from captive mouflons. On these faecal samples qualitative and quantitative parasitological analyses were performed; moreover, faecal cultures were made in order to identify the involved Eimeria species. Significantly higher prevalence (%) and mean intensity (mean OPG +/- SD) of coccidian infection resulted for captive mouflons (73.17% and 814.6 +/- 1297.2 OPG) comparing to wild mouflons (36.73% and 112.7 +/- 268.7 OPG). Eimeria parva, E ovinoidalis, E. bakuensis, E. ahasata, E. intricata, E. crandallis, E. granulosa, E. faurei and an Eimeria species very similar to the descriptions previously reported for E. arloingi and E. yakimoffmatschoulsky, were isolated.

Abstract
Spirocerca lupi (Rudolphi 1809) is a cosmopolitan nematode of dogs and wild carnivores. In the past it has been reported in Italy, mainly in southern regions and in Sicily, where the parasite was observed in foxes in 2005. The parasite typically produces nodular masses in the oesophagus and thoracic aorta. During the 2003-2004 hunting season, the authors investigated a total of 55 foxes (Vulpes vulpes) hunted or killed by car accidents in the provinces of Palermo and Agrigento. All the foxes were subjected to necropsy and 6 (9.16%) had S. lupi nodules located exclusively in the gastric wall. The nature of the nodules was determined by opening them and detecting the nematodes inside, which were identified as S. lupi. Some of the nodules were characterized anatomopathologically and histopathologically. The formation of the parasitic nodule in the stomach only suggests a deviation from the route commonly followed by the nematode to reach the oesophagus, the elective anatomical site for completion of its lifecycle. This survey gives a contribution to the epidemiology of this parasite which is severely outdated in Italy and highlights some distinctive features of the life cycle and parasite migration.

Abstract
The significance of zoonoses varies depending on many socio-economic factors and on the specific situation that prevails in a specific area. The role of the media often determines the importance given to a disease. In resource-rich countries, a zoonosis may be perceived as being important due to inaccurate information that has been circulated by mass media on the risk of infection for animals and humans and on the possible use of the agent for terrorist actions. Images of sick or dead people and animals, drastic methods of control and others, can contribute to an overestimation of the significance of a disease. Information can be lacking or absent in regard to socio-economic factors that clarify occurrence and also on geographic distribution. Therefore, the sensitivity of people can be influenced rapidly and negative socio-economic consequences can occur. These zoonoses can be named 'media-oriented (emphasised) zoonoses'. On the contrary, some zoonoses are scarcely considered for several reasons, for instance: occurrence in poverty-stricken areas and populations, risks of infection for people not considered important enough to deserve medical care, little interest from the media, decision-makers and health services, lack of information and official reports. These zoonoses can be named 'neglected zoonoses'. Some examples of zoonoses included in the above categories are described.

Abstract
Thirty-six tortoises (Testudo hermanni) with naturally acquired oxyurids infections were used to assess the anthelmintic efficacy of oxfendazole (Dolthene; Merial) and fenbendazole (Panacur; Hoechst Roussel Vet). Animals were randomly assigned to three groups (A, B, and C) based on sex and weight. Animals in group A (seven males and six females) were orally treated with oxfendazole at dose rate of 66 mg/kg, group B animals (nine males and eight females) were orally treated with fenbendazole at dose rate of 100 mg/kg, and group C animals (three males and three females) were not treated and served as controls. All animals were individually stabled in plexiglas boxes under controlled conditions of temperature, humidity, and light beginning 7 days pretreatment and continuing for the duration of the trial. Individual tortoises feces were examined daily by the McMaster technique and drugs efficacy was assessed by the fecal eggs count reduction (FECR) test. Both drugs showed 100% of FECR. However, oxfendazole reached this level 12 days after treatment, whereas 31 days after treatment were necessary to obtain the same stable result with fenbendazole. The two drugs were well tolerated by all the animals and no adverse reactions were observed after treatment.

Abstract
We tested 731 sera from apparently healthy light horses against Chlamydophila pneumoniae, by a microimmuno-fluorescence (MIF) test. To verify cross-reactions with other species of chlamvdiae, all sera with an antibody titre > or = 32 to C. pneumoniae were tested against both C. psittaci and C. abortus. Antibodies to C. pneumoniae were detected in 194 out of 731 (26.5%) samples tested, with antibody titres ranging from 32 to 1024. No antibody titre > or = 32 was detected in sera to C. abortus. Only few sera with a high antibody titre to C. pneumoniae reacted weakly with C. psittaci at the dilution of 1:32.

Abstract
Milk production has been a distinguishing characteristic of sheep breeding since antiquity in the Mediterranean area, including Italy, where prehistoric findings confirm this particular husbandry activity. In Homer's Odyssey, the description of Polifemo's sheep flock organization is remarkably similar to current production systems. The ancient roots of this tradition have grown into an important economic reality, with excellent levels of milk production and apporoximately 65 typical cheeses. It is interesting to note that the Italian word "pecora" (sheep) is believed to have originated from the Latin "pecunia" (money). Although heavy production losses are due to parasitic infections, only 250 papers have been published in the last 50 years in Italy on sheep parasites. Differences in climate, environmental factors and production tecniques may influence infection prevalence, load and pathogenesis. For this reason, prevention must be aimed at the particular epidemiological situation and not simply adapted from current schemes used abroad. The aim of this paper is to illustrate the epidemiology of ovine gastrointestinal nematodes in Italy and to evaluate the economic importance of their control.

Owing to the recent emergency of urban faecal pollution it is important to point out new strategies in order to fight the problem starting with the knowledge of past experiences. A punctual chronography of the different approach (telluric, coprological--zoonotic and phenomenological) was attempted to furnish a scientific base for future, modern approach.

Abstract
In recent years leishmaniasis has become a serious Public Health problem in Italy. The coexistence of infected dogs, vectors and humans, makes urban areas suitable environment for the spread of this zoonotic disease. With the purpose to improve the current system for the control of leishmaniasis in urban areas, the authors report their experiences carrying out a Health Information System (HIS) for the surveillance of the disease in the city of Messina. The HIS project is built on a dataset containing geographical data on urban environment, census tracts at parish level and data of human and canine leishmaniasis cases reported in the last years. The HIS allows the spatial representation of the disease occurrence and can be used as a novel epidemiological tool to perform area-based surveillance.

Abstract
The world is rapidly changing in many aspects concerning veterinary medicine, and man-animal relationships in urban areas represents a real challenge for the profession. Unlike the vertical approach of the academic teaching tradition, veterinary urban hygiene needs a strong holistic-epidemiologic support. Year by year, new animals, new animal uses, new fashions, new zoonoses, and new problems appeared amplified by media with the duty of the public veterinary services to solve them. The practical experience of many years of these continuous challenges is now concentrated on a new health sector: urban veterinary hygiene that now calls for a multidisciplinary and intersectoral collaboration with other professional categories to guarantee human, animal and environment health.

Abstract
Two hundred and six samples of alpine marmot (Mamota marmota) hair (148 from adults and 58 from young subjects), 102 soil samples from the entrances to the burrows of the above individuals and 20 control specimens (obtained from adjoining areas away from the burrow systems where the rodents are not usually present) were examined from May 1994 to September 1997. Seventy-five isolates belonging to six species of dermatophytes were found in 69 of the 206 hair samples examined (33.5%). Two species were zoophilic, Microsporum canis (7.8%) and Trichophyton mentagrophytes (11.2.%), and four geophilic, Microsporum cookei (2%), M. gypseum (5.8%), Trichophyton ajelloi (3.9%) and T. terrestre (5.8%). The prevalence of each species in the hair samples did not change significantly according to year, season (chi-squared test [limit significance: P <0.05] gives no significant values [P>0.05] both in year and in season comparison) or age/sex (adult versus juvenile: P=0.1; male versus female: P=0.8) of the marmot. Twenty-three of the 102 soil samples (22.5%) were positive for dermatophytes found in the hair of marmots from the same burrow systems. Five of the 20 control soil samples (25%) were positive for dermatophytes. One isolate of M. gypseum, three of T. terrestre and one of T. mentagrophytes were obtained. Compared with other free-ranging rodent hosts studied in Europe, this mycoflora is characterized by the presence and relatively high prevalence of M. canis, frequently reported in symptomatic and asymptomatic cats, dogs and fur animals. M. canis has not been isolated in other rodents in the wild. However, it has recently been reported in asymptomatic foxes (Vulpes vulpes) from northern Italy. The close link between V vulpes and M. marmota, with the former representing the most important mammal predator of the latter in the Alps (only a fraction of the predator's attacks result in the death of the rodent) may have favoured the adaptation of M. canis to this rodent host. The stable character of the M. canis/M. marmota relationship (no seasonally or annually related difference in the prevalence of this dermatophyte has been found) suggests the inclusion of the alpine marmot in the reservoir of this zoophilic pathogenic agent. In this situation, hibernation in labyrinthine burrow systems, where temperature and moisture ranges are quite uniform the whole year round, may favour the viability of M. canis arthroconidia, whose survival in mountain habitat might otherwise be compromised. This seems to be confirmed by the fact that the fungus has never been found in the control samples collected at a distance of 300 m from the outer edge of the sampled burrow systems.

Abstract
In recent years wildlife diseases (infectious and non-infectious) have played a relevant role in both wildlife conservation and public health. Global environmental changes have determined a bimodal evolution of wildlife. On one side a huge loss of biodiversity has been observed leading to the increasing of threatened or endangered species. In contrast few opportunistic taxa increased their aboundances and ranges. The above scenarios claim the intervention of wildlife veterinarians. In conservation the understanding of the ecological role of the host parasite relationship and the perturbations on the host population dynamics have to be assessed and eventually modified. In public health the increased overlapping among wildlife, livestock, pets and human beings represents a risk for diseases spread (no matter in which directions). Serious limits are, still now, observed in the acceptance of this 'new world' by veterinary academics. As a consequence curricula often fail in providing adequate skill at both undergraduate and graduate levels. An addressed approach towards wildlife diseases should be promoted as an essential component of environmental management.

Abstract
The authors report the efficacy of orally administered moxidectin for the prevention of canine heartworm infection in two endemic areas in northern Italy. Two trials were conducted on a total of 257 dogs, including 137 treated with moxidectin (minimum dose of 3 mcg/kg body weight), 85 with ivermectin (minimum dose 6.6 mcg/kg b.w.) and 35 untreated controls. Results of testing for microfilariae and circulating adult female antigens were negative for all treated dogs at the end of both trials. No adverse reactions to moxidectin were observed. In the study areas, prevalence values for Dirofilaria immitis infection calculated on the basis of the untreated controls and testing dogs which had no preventive treatment in the previous transmission season ranged 23-65%. This study confirms the efficacy and safety of moxidectin in the prevention of adult heartworm infection in dogs.

Abstract
Examinations for heartworm (Dirofilaria immitis) were performed on 175 impounded dogs from a hyperendemic area of the Po Valley (Italy). Each blood sample was used with five haematological diagnostic methods (filtration, direct smear, modified Knott, clotted blood and capillary tube) and three commercial ELISA kits (PetChek, Diasystems, Uni-Tec). The results were compared with the true infection status obtained from post-mortem examination of the heart, pulmonary arteries, thoracic venae cavae and lungs. The prevalence of the infection by adult worms at necropsy was 63%. The sensitivity of the tests ranged from 60% (capillary tube) to 81% (Diasystems) and the specificity from 88% (filtration) to 98% (PetChek). The results of all the tests differed significantly (p < 0.01) from those obtained at necropsy. The sensitivity of the tests was also assessed with respect to the differing numbers of worms in the hosts. A positive correlation between the worm burden and the sensitivity was observed in all the tests. It is apparent that the ELISA methods were better able to detect cases with a low number of worms than the haematological tests.

Abstract
A survey was carried out in northern Italy (Veneto and Friuli Venezia Giulia Regions) to assess the extension of canine heartworm disease close to the classic hyperendemic areas of the Po Valley. A filtration test on 275 privately owned dogs showed a mean prevalence of 44%, with a peak of 55% in the Venice province. A high prevalence (17%) of occult filariosis was discovered using a serological test. These values fall within the medium-high range previously reported from other Italian areas. The provinces of Pordenone, Udine, Trieste, Treviso and Belluno, where no cases had been previously reported, were found to be infected. The distribution of the infection did not differ significantly with the dogs' origin or sex. The prevalence seemed to be influenced significantly (p < 0.01) by the hosts' age, function and degree of outdoor activity, reflecting the different exposure risks.

Abstract
From November 1990 to June 1991, 2273 Dirofilaria immitis were collected from 175 stray dogs euthanized in the province of Padua. The breed, sex, age and weight of each animal were noted. The worms were counted, sexed, differentiated as adults or fifth-stage larvae and weighed, and their length was measured. The host-parasite relationship in this epidemiological situation was characterized by a high prevalence (67%) together with a low intensity (19) and abundance (13). The frequency distribution of the parasites in the population of dogs followed a negative binomial pattern (k = 0.3177), showing a good, stable host-parasite relationship. The major risk of infection was in late July and August, some new infections being established in October and, maybe, in November. The majority of dogs that acquired new infections were young animals probably because of an immune response in older dogs. However, the prevalences increased (p < 0.01) in dogs from 1 to 5 years old, in shepherd and hunting dogs compared to the other breeds, and in large as opposed to small dogs. Microfilaraemia (range 1-1,883,000/ml) correlated, as a trend, with the number of adult filariae, which also correlated with the age and the weight of the dogs (p < 0.01). No significant correlations were found between the length or weight of the adult filariae and the data from dogs.
