Abstract
Cryptosporidium spp., Enterocytozoon bieneusi and Encephalitozoon spp. are the most common protistan parasites of vertebrates. The results show that pigeon populations in Central Europe are parasitised by different species of Cryptosporidium and genotypes of microsporidia of the genera Enterocytozoon and Encephalitozoon. A total of 634 and 306 faecal samples of captive and feral pigeons (Columba livia f. domestica) from 44 locations in the Czech Republic, Slovakia and Poland were analysed for the presence of parasites by microscopy and PCR/sequence analysis of small subunit ribosomal RNA (18S rDNA), 60 kDa glycoprotein (gp60) and internal transcribed spacer (ITS) of SSU rDNA. Phylogenetic analyses revealed the presence of C. meleagridis, C. baileyi, C. parvum, C. andersoni, C. muris, C. galli and C. ornithophilus, E. hellem genotype 1A and 2B, E. cuniculi genotype I and II and E. bieneusi genotype Peru 6, CHN-F1, D, Peru 8, Type IV, ZY37, E, CHN4, SCF2 and WR4. Captive pigeons were significantly more frequently parasitised with screened parasite than feral pigeons. Cryptosporidium meleagridis IIIa and a new subtype IIIl have been described, the oocysts of which are not infectious to immunodeficient mice, whereas chickens are susceptible. This investigation demonstrates that pigeons can be hosts to numerous species, genotypes and subtypes of the studied parasites. Consequently, they represent a potential source of infection for both livestock and humans.

Almeida KC, Pinto-Ferreira F, Navarro IT, Souza KL, Balbino LS, Bernardes JC, Bahia Dos Santos DL, Falbo MK. Occurrence of zoonotic enteric parasites in fecal samples from dogs in shelters, parks, squares and public roads, and the dog guardians' perception of zoonoses as for the risk to public health in the city of Guarapuava, Paraná, Brazil. Top Companion Anim Med 2024; 58:100826. [PMID: 37884174 DOI: 10.1016/j.tcam.2023.100826] [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: 01/24/2023] [Revised: 08/30/2023] [Accepted: 10/22/2023] [Indexed: 10/28/2023]
Abstract
The aim of this study was to determine the occurrence of zoonotic enteroparasites in the feces of dogs from public shelters, squares, parks, and public roads in the city of Guarapuava, Paraná, Brazil, and to evaluate the perception of dog guardians regarding zoonoses and their risk to public health. Fecal samples were collected, coproparasitological examinations were performed to detect zoonotic enteroparasites, and polymerase chain reaction (PCR) was used to identify Giardia spp. and Cryptosporidium spp. Questionnaires were given to guardians who walked their dogs in parks, squares, and public roads, as to assess their perception of zoonoses. A total of 333 samples were collected, of these 75, 123, and 135 of them were from public shelters, squares and parks, and public roads, respectively. One or more parasites were identified in 166 (50 %) samples, of which 58/75 (77 %) were from public shelters, 50/123 (41 %) from squares and parks, and 58/135 (43 %) from public roads. The parasites detected included Ancylostoma spp., Giardia spp., Trichuris spp., Toxocara spp., and Cystoisospora spp., with Ancylostoma spp. having the highest occurrence. PCR was performed on 161 samples for convenience due to financial limitations, because only a portion of the study was funded by the municipal government, of which 15.6 % were positive for Giardia spp., and all were negative for Cryptosporidium spp. In total, 246 guardians were interviewed, of which 36 % said they did not collect their animals' feces during walks, 20 % did not use anti-helminthics on their dogs, and 23 % did not know which diseases could be transmitted by feces. Therefore, we conclude that there is a high infection rate of parasites with zoonotic potential in public places, showing the need to raise awareness among guardians about the diseases transmitted by dog feces, correct vermifugation and the importance of collecting feces in public places.

Abstract
Cryptosporidium spp. and Giardia duodenalis are enteric protozoan pathogens in humans. and animals. Companion animals infected with zoonotic species/assemblages are a matter of major public concern around the world. The objectives of the present study were to determine the prevalences of Cryptosporidium spp. and G. duodenalis infections and their co-infection statuses in dogs and cats living in Taiwan and to identify the species and assemblages. Fecal samples were collected from local animal shelters (n = 285) and a veterinary hospital (n = 108). Nested polymerase chain reaction (PCR) was performed using the SSU-rRNA, β-giardin, and glutamate dehydrogenase genes for Cryptosporidium spp. and G. duodenalis, respectively. Results showed that the overall prevalences of Cryptosporidium and G. duodenalis were 7.38% (29/393) and 10.69% (42/393). In addition, co-infection was detected in 1.02% (4/393) of all samples. Sample source, clinical sign, and breed may be risk factors that influence the infection rate. In Cryptosporidium-positive samples, C. canis and C. felis were detected most frequently. Although the canine-specific assemblages C and D (37/42) were dominant, the zoonotic human-specific assemblage A (1/42) was also found in Giardia-positive samples. Phylogenetic analysis revealed that most positive samples belonged to host-specific subtypes/assemblages, while some Cryptosporidium or Giardia-positive samples could be zoonotic. The findings suggested that pet animals could be a cause of zoonotic transmission, causing human cryptosporidiosis and giardiasis in Taiwan.

Abstract
Haemoproteus columbae is a common haemosporidian parasite of wild pigeons (Columba livia) reported worldwide. In Thailand, the wild pigeon population is increasing due to paddy field monoculture. However, there are limited reports on the presence of H. columbae in these pigeon populations. The aim of the study was to characterize H. columbae in wild pigeons. A total of 87 wild pigeons were examined using microscopic and molecular methods. Haemoproteus columbae was detected in approximately 27.6% of pigeons and their morphological characteristics were described. The partial cytochrome b (cyt b) gene sequence of H. columbae was then characterized into three common lineages (HAECOL1, COLIV03, and COQUI05). By highlighting the morphologic and genetic characteristics of H. columbae commonly found in this population of pigeons, this study provides essential regional knowledge about haemosporidian parasites that could benefit future taxonomic and phylogeographic studies.

Abstract
Background We aimed to characterize Cryptosporidium spp. in rats, cats, pigeons, and crows. Methods Fifty-five animal origin Cryptosporidium spp. genome were identified, genotyped and confirmed by nested PCR and of RFLP-PCR analysis as well as sequenced based on 18s rRNA and gp60 genes in Tehran (2012-2019). Finally, the phylogenetic analysis was performed by MEGA software (version 7). Results By the molecular method, Cryptosporidium spp. were detected in 24 (15.2%), 15 (15%), 2 (2%) and 13 (13%) cases of wild rats, cat, pigeon, and crow, respectively. Among the identified species by the RFLP pattern, most isolates were identified as C. parvum (24/157) 17.8% in rats, (15/100) 15% in cats, (13/100) 13%in crew and (2/100) 2% in pigeons; and the rest of the cases were C. muris and C. felis. The results of sequencing did not prove the existence of C. parvum, C. felis, C. muris, and rat genotype. Subtyping of C. parvum was indicated that the dominant subtype family belongs to the IId family and the subtype A20G1 was the most common subtype detected in all hosts while A19G1 was detected in one isolate of cat and pigeon. Conclusion Free-ranging animals are infected by species/subtype of Cryptosporidium, which can infect humans. This shows by itself the hygienic importance of the free-ranging animals in urban ecosystems. In the transmission of human cryptosporidiosis, the multi-host Cryptosporidium species such as C. parvum, C. felis, and C. muris can be transferred potentially from these animals to humans.

Abstract
Cryptosporidium is an important intestinal zoonotic pathogen that can infect various hosts and cause diarrheal disease. There are no reports on the prevalence and molecular characterization of Cryptosporidium in wild birds in Cyprus. Therefore, the present study aimed to determine the prevalence of Cryptosporidium spp. and genotypes in wild birds found at Phassouri Reedbeds (Akrotiri Wetlands), Cyprus. Fecal samples of 75 wild birds (Eurasian coot Fulica atra, N = 48; Eurasian teal Anas crecca, N = 20; duck - Anas spp., Ν = 7) were screened for Cryptosporidium by PCR amplification and sequencing. Only one sample (1.3%) belonging to a Eurasian coot was PCR-positive for Cryptosporidium. Based on sequencing of the 18S rRNA locus, this species was identified as Cryptosporidium proventriculi. This is the first report on the molecular identification of this Cryptosporidium species in a Eurasian coot.

Abstract
Pigeons have been considered the most preferred companion for human civilizations since prehistoric times. Despite the fact that pigeons offer the most palatable and nutritious food and provide pleasure to humans, they can pose a health risk because of carrying infectious and zoonotic organisms. Moreover, the scanty of systematic reports on the occurrence of zoonotic pathogens in pigeon makes the situations worst. Hence, the current study conducted a systematic review and meta-analysis to evaluate the global prevalence of zoonotic pathogens among the pigeon population from existing segregated literatures. Four internationally recognized databases including Google Scholar, Scopus, PubMed, and Science Direct were used to search the published studies from January 2000 to October 2021. Analyzing the total 18,589 samples, mean prevalence estimates of pigeon pathogens worldwide were found to be 17% (95% CI:13-21) whereas serological and molecular prevalence were reported as 18% (95% CI:12-23) and 17% (95% CI:10-23). Meanwhile, virus, bacteria, and protozoal pathogens were found to be 21% (10-32%), 17% (12-23%), and 14% (10-19%), respectively. Moreover, continent wise analysis of all zoonotic pigeon pathogens has revealed the highest prevalence rate in Asia 20% (95% CI: 14-26%), followed by Europe 16% (95% CI: 08-24%), Africa 16% (95% CI: 07-24%), and America (North and South) 10% (95% CI: 03-17%). Furthermore, the highest number of studies were reported from Iran showed the prevalence rate of 20%, China 13%, Bangladesh 37%, and Poland 15%. Therefore, this prevalence of data would be helpful to the policymakers to develop appropriate intervention strategies to prevent and control diseases in their respective locations.

Abstract
Background Intestinal infection, caused by various protozoans and helminths, represents one of the significant health concerns in pigeons around the world. Objectives The present study aimed to determine the diversity and prevalence of the intestinal parasites in pigeons found in Ratnanagar Municipality, Chitwan, in central Nepal. Methods The fresh faecal samples (n = 155) were non‐invasively collected from different households and temples pigeons The individual samples were immediately preserved in the 2.5% potassium dichromate solution and transported to the research laboratory. Following direct wet mount and concentration methods, the samples were observed under a compound microscope. Results The results showed 87.1% prevalence rate with 16 parasite species that included 8 protozoan and 8 helminth faunae. The faecal samples of temple pigeons contained a higher prevalence rate with higher parasitic richness (95.6%; 16 species) than household pigeons (75.4%; 12 species). Mixed infection up to four different species was recorded in both types of sampling populations. Conclusions Pigeons harbour a greater prevalence and wider diversity of intestinal parasites and the parasitism varies based on the habitats. Proper management and effective deworming practices are recommended to control intestinal parasitic infection in these avian hosts.

Abstract
Background Cryptosporidium spp. are obligate intracellular apicomplexan parasites transmitted to humans and other animals by contaminated water, food, or direct contact. They mainly cause gastrointestinal symptoms, although subclinical infections are also common. Cats are primarily infected by host-adapted Cryptosporidium felis while C. parvum and C. muris have also been detected in some cases. In this study, the molecular prevalence of Cryptosporidium spp. was investigated by screening 399 fecal samples collected from stray cats using nested PCR targeting the 18S rRNA gene for the first time in Turkey. Additionally, Cryptosporidium PCR-positive samples were genotyped by nested PCR- restriction fragment length polymorphism (RFLP), and subsequently, amplicons of 18S SSU rRNA were sequenced. They were further subtyped by amplification and sequencing of the gp60 gene. Results Among fecal samples screened, 12 of them (3%) were found to be Cryptosporidium-positive, and according to RFLP and sequencing of 18S rRNA gene, all positive samples were identified as C. felis. Subtyping analyses at the gp60 gene showed that C. felis isolates belonged to the XIXa subtype family, which are closely related to human subtypes of the parasite. Conclusions The results of this study are important in terms of indicating the potential role of stray cats for transmission of Cryptosporidium spp. to humans or other animals. Also, the presence of XIXa, which is the dominant subtype family of C. felis in cats and humans was shown for the first time in stray cats of İzmir, Turkey.

This survey assessed the presence of avian influenza virus (AIV) in urban feral pigeons (UFPs) in Bangkok, Thailand. A total of 485 UFPs were collected from eight study sites, and blood, tracheal, and cloacal samples were collected from each bird. Virus isolation and molecular methods did not detect AIV in any of the birds tested. A hemagglutination inhibition test was used to test for antibodies to high and low pathogenicity AIV subtypes. AIV subtype H9 antibodies were the only antibodies detected. The overall seroprevalence of AIV subtype H9 antibodies was 6.9%, and subtype H9 antibodies were found in UFPs at all eight sites. The overall geometric mean titer was 11.07 (range: 8-64). These results reveal that UFPs in Bangkok do not currently pose a risk of transmitting AIV to humans. However, monitoring of AIV in UFPs is necessary for disease control and to minimize the possibility of influenza outbreaks.

[PMID: 34578141 PMCID: PMC8466027 DOI: 10.3390/pathogens10091107] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2021] [Revised: 08/23/2021] [Accepted: 08/23/2021] [Indexed: 11/25/2022] Open
Abstract
Giardia duodenalis, Enterocytozoon bieneusi and Cryptosporidium spp. are common enteric pathogens that reside in the intestines of humans and animals. These pathogens have a broad host range and worldwide distribution, but are mostly known for their ability to cause diarrhea. However, very limited information on prevalence and genotypes of G. duodenalis, E. bieneusi and Cryptosporidium spp. in pet dogs and cats are available in China. In the present study, a total of 433 fecal samples were collected from 262 pet dogs and 171 pet cats in Yunnan province, southwestern China, and the prevalence and the genotypes of G. duodenalis, E. bieneusi and Cryptosporidium spp. were investigated by nested PCR amplification and DNA sequencing. The prevalence of G. duodenalis, E. bieneusi and Cryptosporidium spp. was 13.7% (36/262), 8.0% (21/262), and 4.6% (12/262) in dogs, and 1.2% (2/171), 2.3% (4/171) and 0.6% (1/171) in cats, respectively. The different living conditions of dogs is a risk factor that is related with the prevalence of G. duodenalis and E. bieneusi (p < 0.05). However, there were no statistically significant difference in prevalence of three pathogens in cats. DNA sequencing and analyses showed that four E. bieneusi genotypes (PtEb IX, CD9, DgEb I and DgEb II), one Cryptosporidium spp. (C. canis) and two G. duodenalis assemblages (C and D) were identified in dogs; two E. bieneusi genotypes (Type IV and CtEb I), one Cryptosporidium spp. (C. felis) and one G. duodenalis assemblage (F) were identified in cats. Three novel E. bieneusi genotypes (DgEb I, DgEb II and CtEb I) were identified, and the human-pathogenic genotypes/species Type IV C. canis and C. felis were also observed in this study, indicating a potential zoonotic threat of pet dogs and cats. Our results revealed the prevalence and genetic diversity of G. duodenalis, E. bieneusi and Cryptosporidium spp. infection in pet dogs and cats in Yunnan province, southwestern China, and suggested the potential threat of pet dogs and cats to public health.

Abstract
Cryptosporidiosis is an important zoonosis caused by Cryptosporidium. This disease causes a global public health problem. The cat is considered to be one of the potential hosts for transmitting Cryptosporidium to humans. In this study, a global meta-analysis for Cryptosporidium infection in cats was performed. The articles related to Cryptosporidium infection in cats were systematically searched in databases China National Knowledge Infrastructure (CNKI), Wanfang data, VIP Chinese Journal Database, PubMed, and ScienceDirect. Finally, 92 articles published from 1988 to 2021, which met the criteria of systematic review and meta-analysis, were collected. During the selected period, the overall prevalence of Cryptosporidium among cats was identified to be 6.0%. The prevalence of Cryptosporidium detected by microscopy, coproantigens, and molecular biology methods were 4.2%, 8.2%, and 5.0%, respectively. Among 9 species/genotypes (C. felis, C. parvum, C. muris, Cryptosporidium rat genotype IV, C. baileyi, C. ryanae, C. hominis, Cryptosporidium sp. rat genotype III and most closely related to Cryptosporidium sp. rat genotype III), the prevalence of C. parvum (4.2%) was significantly higher than that of other species/genotypes. Among five continents, the prevalence of Cryptosporidium in Africa (30.5%) was significantly higher than in other continents. We also analyzed the effects of different geographical factors (longitude, latitude, altitude, mean temperature, precipitation, and humidity) on Cryptosporidium infection among cats. The results showed that cryptosporidiosis was common in cats all over the world. This systematic review and meta-analysis has systematically introduced the global epidemiology of Cryptosporidium in cats and correlated risk factors. Health authorities, doctors, veterinarians and cat owners' awareness of the prevalence, risk factors and complications of Cryptosporidium are important for the development of effective prevention strategies for cryptosporidiosis.

Molecular detection of Giardia duodenalis and Cryptosporidium spp. from stray dogs residing in monasteries in Bangkok, Thailand. Parasitol Int 2021; 83:102337. [PMID: 33771679 DOI: 10.1016/j.parint.2021.102337] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2020] [Revised: 03/16/2021] [Accepted: 03/16/2021] [Indexed: 11/28/2022]
Abstract
Both Cryptosporidium spp. and Giardia duodenalis are enteric protozoan parasites that infect a wide variety of domestic animals as well as humans worldwide, causing diarrheal diseases. Giardia duodenalis assemblages C and D are specific to canine hosts and zoonotic assemblages A and B are also found in dogs as a reservoir host. In dogs, Cryptosporidium canis is the host-specific species while humans are infected by C. hominis and C. parvum and at least another 16 zoonotic Cryptosporidium species have been reported causing human infections, with C. meleagridis, C. viatorum, and C. ubiquitum being the most frequent. The objective of this study was to determine the prevalence of Cryptosporidium spp. and G. duodenalis from stray dogs in areas of Bangkok and to identify the species and assemblages. Fecal samples (540) were collected from dogs residing in 95 monasteries in 48 districts in the Bangkok metropolitan area. Nested Polymerase Chain Reaction (PCR) was performed using the ssu-rRNA gene for both parasites. In total, 3.0% (16/540) samples were positive for G. duodenalis, with most being G. duodenalis assemblage D (7/16) followed by assemblage C (7/16) and zoonotic assemblage A (2/16). The prevalence of Cryptosporidium spp. was 0.7% (4/540) based on the PCR results and all were the dog genotype C. canis. These results indicated that dogs residing in Bangkok monasteries poses a limited role as source of human giardiosis and cryptosporidiosis.

Altamimi MK, Al-Zubaidi MTS. High Prevalence of Cryptosporidium meleagridis in Domestic Pigeons (Columba livia domestica) Raises a Prospect of Zoonotic Transmission in Babylon Province, Iraq. THE IRAQI JOURNAL OF VETERINARY MEDICINE 2020.

Abstract
Cryptosporidium is one of the most common protozoan’s parasites with remarkable infectivity of a wide range of animals, including mammals and birds. Domestic pigeons (Columba livia domestica) act as a potential reservoir for several species of Cryptosporidium because they live in close proximity to humans. This study was conducted to assess the genetic diversity of Cryptosporidium in domestic pigeons in Iraq. A total of one hundred samples obtained from feces of domestic pigeons in Babylon province were included. After being exposed to microbial examination, all fecal samples were subsequently screened by nested polymerase chain reaction (PCR) for the possible recognition of Cryptosporidium species. Microscopy tests detected only 14/100 (14%) of infection with Cryptosporidium, while molecular tests detected 21/100 (21%) of the same targeted parasite. Sequencing experiments showed a high prevalence of C. meleagridis with 13/21 (61.90%), followed by C. baileyi with 7/21 (33.33%), while only one infection was detected with C. hominis (1/21) (4.76%). No co-infection with mixed Cryptosporidium spp. was observed, and sex factor was not found to affect the infection rate. In conclusion, this study informed a high prevalence of C. meleagridis in domestic pigeons than both C. baileyi and C. hominis, respectively, signifying a higher zoonotic potential of C. meleagridis between domestic pigeons and their handlers. This finding may raise more questions with regard to the increasing infectivity of C. meleagridis in human. This is the first important screening study in Iraq that uses molecular methods for the detection of Cryptosporidium in domesticated pigeons.

Abstract
BACKGROUND Cryptosporidiosis is an acute and short-term infection which can lead to severe diarrhea (intestinal cryptosporidiosis) associated with a persistent cough in the host with immune system defect. This systematic review and meta-analysis was conducted to estimate the prevalence of animal Cryptosporidium species and the corresponding epidemiological aspects in Iran. METHODS In this study, all original research articles relating to the animal cryptosporidiosis in Iran were collected from reliable databases using keywords. A meta-analysis was conducted separately for each subgroup, and heterogeneity among the studies was performed using the Q and I2 tests. Furthermore, it should be noticed that the significance level in the statistical analysis with the Comprehensive Meta-analysis software was considered to be less than 0.05. Finally, meta-analysis results were shown in forest plot with a 95% CI. RESULTS In total, 4795 studies were included in the initial screening. Duplicated or non-original studies and the ones which did not meet our considered criteria were excluded from the list. Out of the 100 articles included in our first list for the meta-analysis, 40, 16, 13, 10, 9, 7, and 5 were done on cattle and calves, birds, dogs, sheep, rodents, camels, and horses, respectively. The prevalence rate of cryptosporidiosis among the birds, horses, rodents, camels, dogs, cattle, and sheep in Iran was estimated to be 7.5%, 19.5%, 20.8%, 8.4%, 4.9%, 14.4%, and 9.1%, respectively. CONCLUSION The different Cryptosporidium species have been found in different regions of Iran. Geographical region, climate, and domestic animals are considered as factors responsible for animal cryptosporidiosis prevalence in the area. Moreover, this parasite is zoonotic which causes disease in animals as well as humans which can result in economic loss.

Abstract
Cryptosporidium spp. are parasites with zoonotic potential that cause intestinal diseases, generally intense diarrheal, on their hosts, which tend to be immunocompromised. Large populations of pigeons in urban environments can lead to greater human exposure to Cryptosporidium spp., as this bird is considered a potential reservoir and is able to transmit several pathogens. This study aimed in determining the occurrence of Cryptosporidium spp. oocysts in feces of free-living pigeons (Columba livia) found in urban areas in the city of Pelotas, Rio Grande do Sul, south of Brazil. Fecal samples (n = 50) were collected from young and adult pigeons captured in different locations in the urban area and the parasitological diagnosis was performed through Ritchie's modified technique and Kinyoun's technique. Among the 50 samples, 18% (IC95% 9.7-30.8) were positive for Cryptosporidium spp. with a low number of oocysts being detected on fecal smears. Our results confirmed the occurrence of Cryptosporidium spp. oocysts in feces of free-living pigeons from the urban area of the city of Pelotas. This is the first report of Cryptosporidium spp. oocysts in feces of pigeons in south Brazil. This data has epidemiological significance because the oocysts could be from zoonotic species, which consequently shows that humans might be exposed to infection.

Abstract
Cryptosporidium spp. is an important intestinal protozoan causing diarrhea among both healthy and immunocompromised patients especially those with HIV/AIDS. Cryptosporidium spp. can be transmitted via foodborne, waterborne and person-to-person routes. In addition, several Cryptosporidium species are zoonotic. This study aimed to determine the prevalence of Cryptosporidium infection among pigs raised in both smallholder (<50 heads/farm) and large scale farms (50-500 heads/farm) in Chonburi Province, eastern Thailand using nested PCR amplifying the small subunit of the ribosomal RNA (SSU-rRNA) gene. DNA sequencing was also performed to identify the species of Cryptosporidium. A total of 245 fecal samples were collected from 11 pig farms. The overall prevalence of Cryptosporidium infection was 20.8% (51/245) which were found in both smallholder and small large scale pig farms. The prevalence of Cryptosporidium infection among pigs aged ≤6 months was significantly higher than those aged >6 months (p < .001). Among 51 Cryptosporidium positive samples, Cryptosporidium scrofarum (42/51, 82.4%) and Cryptosporidium suis (9/51, 17.6%) were identified. The prevalence of C. scrofarum infection observed among pigs aged ≤6 months was significantly higher when compared with those aged >6 months (20.7% and 2.1%, respectively, p < .001). The high prevalence of C. scrofarum and C. suis infections among pigs could be a potential source of infection to humans.

Abstract
Cryptosporidium is an opportunistic parasite that has been reported in >30 avian hosts worldwide, however, there is no information regarding Cryptosporidium spp. in poultry in Bangladesh. Accordingly, we investigated the prevalence of Cryptosporidium spp. in poultry at open live bird markets in Bangladesh. A total of 197 samples were randomly collected from poultry at open live bird markets in Bangladesh and screened for the detection of Cryptosporidium. Initial microscopic examination revealed Cryptosporidium spp. was observed in 19.8% (39/197) of the poultry specimens. Subsequent nested PCR targeting the 18S rRNA gene revealed that 15.7% (31/197) of the samples were Cryptosporidium positive. Of these 31 samples, 17 were Cryptosporidium baileyi (8.7%), 12 were Cryptosporidium meleagridis (6.0%), and 2 were Cryptosporidium parvum (1.0%). Nucleotide sequence analysis of the GP60 gene of the C. meleagridis revealed that two subtypes (IIIbA21G1R1 and IIIbA23G1R1), which were found in broiler, native and sonali chickens and a pigeon, matched those previously reported in humans and poultry. We identified two novel subtypes (IIIbA21G2R1 and IIIbA20G2R1) in sonali chickens, a broiler chicken and a layer chicken. We also amplified the GP60 gene of C. parvum and found two subtypes (IIaA11G2R1 and IIaA13G2R1) in a sonali and a broiler chicken that were previously reported in calf. These findings suggest that poultry can be a source of cryptosporidial infections for humans and animals in Bangladesh. This is the first molecular investigation of Cryptosporidium genotypes and subtypes in poultry at open live bird markets in Bangladesh. Cryptosporidium genotypes and subtypes in poultry in Bangladesh have been investigated firstly. Cryptosporidium baileyi, C. meleagridis and C. parvum are identified while C. baileyi is predominant species in poultry. Two novel subtypes (IIIbA21G2R1 and IIIbA20G2R1) of the C. meleagridis in chickens are detected. Cryptosporidium parasites are common among the live bird markets in Bangladesh.

Abstract
BACKGROUND Enterocytozoon bieneusi and Cryptosporidium spp. are prevalent zoonotic parasites associated with a high burden among children. To date only limited molecular epidemiological data on E. bieneusi and Cryptosporidium spp. in humans living in Thailand has been published. METHODS PCR-based tools were used to detect and characterize E. bieneusi and Cryptosporidium spp. The internal transcribed spacer (ITS) region of the rRNA gene was used to investigate E. bieneusi, and the small subunit (SSU) rRNA gene was used to investigate Cryptosporidium spp., and 697 fecal samples from villagers and school children in rural areas in Thailand were analyzed. RESULTS The infection rates were 2.15% (15/697) for E. bieneusi and 0.14% (1/697) for Cryptosporidium spp. The prevalence of E. bieneusi was significantly high in Loei province. Sequence analysis indicated that the Cryptosporidium isolate was C. parvum. Nine E. bieneusi genotypes were identified, EbpC, Peru12, TMH6, TMH3, TMH7, H, D, and two novel genotypes TMLH1 and TMLH2. E. bieneusi prevalence was significantly higher in male participants than in female participants, and in children aged 3-15 years than in participants aged > 15 years. CONCLUSIONS The prevalence, genotypes, and zoonotic potential of E. bieneusi were found to vary significantly high even in one country. Transmission routes and key animal carriers of E. bieneusi may be associated with differences in hygiene, sanitation, and cultural behaviors. Further molecular studies including longitudinal studies will be required to unveil epidemiological characteristics of these opportunistic intestinal protozoa in all over the countries.

Abstract
The cat is a reported reservoir for several zoonotic pathogens, including Cryptosporidium spp., Giardia duodenalis, and Blastocystis sp. These parasites represent a significant, but often neglected, threat to humans and animals. Furthermore, Tritrichomonas foetus has been described inhabiting the digestive tract of cats, and may be causative agents of gastrointestinal symptoms. However, scant data are available concerning the molecular epidemiology of these parasites in domestic cats in China. This study examined fecal samples from domestic cats in Eastern China to unravel the molecular epidemiology of four protozoans. Of the 346 samples examined, 47 (13.6%) were positive for the detected pathogens, including 8 (2.3%), 5 (1.4%), 2 (0.6%), and 35 (10.1%) samples positive for Cryptosporidium spp., G. duodenalis, Blastocystis sp., and T. foetus, respectively. Co-infection with Cryptosporidium spp. and T. foetus was detected in three cats, no other mixed infections were observed. No age, sex or fecal condition predisposition was observed with any of the four pathogens. The species/assemblages/subtypes/genotypes were C. felis, Assemblage A and F, ST1, and cat genotype for Cryptosporidium spp., G. duodenalis, Blastocystis sp., and T. foetus detected in this study, respectively. The presence of zoonotic species/assemblages/subtypes/genotypes poses a threat to public health. These findings provide useful information for the design of prevention and control strategies to reduce the burden of protozoal infections in cats.

Abstract
Cryptosporidiosis is a common parasitic infection in birds that is caused by more than 25 Cryptosporidium species and genotypes. Many of the genotypes that cause avian cryptosporidiosis are poorly characterized. The genetic and biological characteristics of avian genotype III are described here and these data support the establishment of a new species, Cryptosporidium proventriculi. Faecal samples from the orders Passeriformes and Psittaciformes were screened for the presence of Cryptosporidium by microscopy and sequencing, and infections were detected in 10 of 98 Passeriformes and in 27 of 402 Psittaciformes. Cryptosporidium baileyi was detected in both orders. Cryptosporidium galli and avian genotype I were found in Passeriformes, and C. avium and C. proventriculi were found in Psittaciformes. Cryptosporidium proventriculi was infectious for cockatiels under experimental conditions, with a prepatent period of six days post-infection (DPI), but not for budgerigars, chickens or SCID mice. Experimentally infected cockatiels shed oocysts more than 30 DPI, with an infection intensity ranging from 4,000 to 60,000 oocysts per gram (OPG). Naturally infected cockatiels shed oocysts with an infection intensity ranging from 2,000 to 30,000 OPG. Cryptosporidium proventriculi infects the proventriculus and ventriculus, and oocysts measure 7.4 × 5.8 μm. None of the birds infected C. proventriculi developed clinical signs.

Abstract
Enterocytozoon bieneusi and Cryptosporidium spp. are important pathogens causing diarrhea in humans and animals. However, few studies have been conducted on the infection of E. bieneusi and Cryptosporidium spp. in peafowl up to now. The purpose of the present study was to determine the prevalence and the involved genotypes of Cryptosporidium spp. and E. bieneusi in peafowl in Beijing and Jiangxi Province, China. In total, 258 peafowl fecal samples were collected. Overall, both Cryptosporidium spp. and E. bieneusi had the same prevalence, i.e. 6.59% (17/258). Higher infection rates of E. bieneusi and Cryptosporidium spp. were found in the adolescent peafowl. The prevalence of E. bieneusi in Beijing and Jiangxi Province was 5.23% and 8.57% respectively. For Cryptosporidium spp., the prevalence was 4.58% and 9.52% in Beijing and Jiangxi Province, respectively. Three zoonotic genotypes of E. bieneusi were confirmed, including two known genotypes, genotype Peru 6 and D, and one novel genotype, JXP1. Two avian specific species/genotypes of Cryptosporidium, Avian genotype Ⅲ and Goose genotype Ⅰ, were identified. To our knowledge, this is the first report of E. bieneusi and Cryptosporidium spp. occurrence in peafowl in China. The findings suggest that peafowl could be reservoirs of E. bieneusi and Cryptosporidium spp. which could be potentially transmitted to humans and other animals, and the present survey have implications for controlling E. bieneusi and Cryptosporidium spp. infection in peafowl. This is the first report of Enterocytozoon bieneusi and Cryptosporidium spp. in peafowl in China. The average infection rate was 6.59% and higher prevalence was found in the adolescent peafowl. Three zoonotic genotypes of E. bieneusi and 2 avian specific genotypes of Cryptosporidium were identified. This study will enrich the epidemiological data of E. bieneusi and Cryptosporidium spp. infection in China.

Abstract
Background Opportunistic infections represent a serious health problem for HIV-infected people. Among enteric infections, cryptosporidiosis, a severe and life-threatening diarrheal disease, is of particular importance in low economic settings where access to anti-retroviral therapy is limited. Understanding transmission routes is crucial in establishing preventive measures, and requires the use of informative genotyping methods. In this study, we performed a retrospective analysis of Cryptosporidium species in 166 stool samples collected from 155 HIV-infected patients during 1999–2004 at the Siriraj Hospital in Bangkok, Thailand. Results Microscopic examination of stools identified 104 of the 155 patients as positive for Cryptosporidium. Other common pathogens identified were microsporidia, Isospora, Giardia, Strongyloides and Opisthorchis. All samples were tested by amplification of a fragment of the 18S rDNA locus, and sequencing showed the presence of Cryptosporidium hominis (n = 42), C. meleagridis (n = 20), C. canis (n = 12), C. felis (n = 7), C. suis (n = 6) and C. parvum (n = 5). Genotyping at the glycoprotein 60 (gp60) locus revealed substantial variability in isolates of C. hominis and C. meleagridis. Among C. hominis isolates, subtype IeA11G3T3 was the most prevalent, but allelic family Id was the more diverse with four subtypes described, two of which were identified for the first time. Among C. meleagridis isolates, seven subtypes, two of which were new, were found in the allelic family IIIb, along with new subtypes in allelic families IIIe and IIIg. In the four C. parvum isolates, subtype IIoA16G1, a rare subtype previously reported in a Swedish patient who had traveled to Thailand, was identified. Conclusions This study confirms the high susceptibility of HIV-infected individuals to infection with different Cryptosporidium species and subtypes, and further stresses the importance of surveillance for opportunistic intestinal protozoans.

Abstract
Currently, there are only three valid species of Cryptosporidium infecting avian hosts, namely, Cryptosporidium meleagridis, Cryptosporidium baileyi, Cryptosporidium galli and Cryptosporidium avium in addition to 12 genotypes of unknown species status. The objectives of this study were to microscopically diagnose the presence of Cryptosporidium in birds from a commercial aviary located in Rio de Janeiro, Brazil; genotypically characterize species and/or genotypes of genus Cryptosporidum; and conduct sequencing and phylogenetic analyses to compare the obtained DNA sequences with those deposited in GenBank. A total of 85 fecal samples were collected from wild captive-bred birds: 48 of family Psittacidae and 37 of family Ramphastidae. Initially, a search for the presence of Cryptosporidium sp. oocysts was conducted using the centrifugal-flotation in saturated sugar solution technique, after that, the collected samples were analyzed microscopically. Cryptosporidium infections were only detected in 24.32% of samples belonging to the family Ramphastidae. DNA was extracted from positive samples and molecular diagnostics was applied targeting the 18S rRNA gene, followed by sequencing and phylogenetic analysis. The Cryptosporidium Avian genotype III was diagnosed in this study more closely related to the gastric species. This is the first record of Cryptosporidium Avian genotype III in order Piciformes and family Ramphastidae, where three host species (Ramphastus toco, Ramphastus tucanus, and Pteroglossus bailloni) were positive for the etiologic agent. Based on the molecular data obtained, these wild birds raised in captivity do not represent a source of human cryptosporidiosis, considering that Cryptosporidium Avian genotype III does not constitute a zoonosis.

Abstract
Cryptosporidiosis is a cosmopolitan parasitosis that affects a wide range of hosts including birds. As information concerning Cryptosporidium in birds is limited, the present study examined the prevalence and genotypes of Cryptosporidium in Java sparrows in Beijing and Shangqiu, northern China. Three hundred and fifty fecal samples were collected from Java sparrows (Lonchura oryzivora, 225 white Java sparrows and 125 gray Java sparrows) in Beijing and Shangqiu in October 2015, and the samples were examined by PCR amplification of the small subunit ribosomal RNA (SSU rRNA) gene. The overall Cryptosporidium prevalence is 13.42% (47/350), with 16.44% (37/225) in white Java sparrows and 8.00% (10/125) in gray Java sparrows. Cryptosporidium prevalence was 9.82% (16/163) in Java sparrows from Beijing and 16.58% (31/187) in Java sparrows from Shangqiu. The prevalence of Cryptosporidium in females and males was 40.63% (26/64) and 7.34% (21/286), respectively. The Cryptosporidium prevalence in Java sparrows of different ages varied from 10.47% to 16.33%. Sequence analysis of the SSU rRNA gene revealed that all the samples represented C. baileyi. This is the first report of Cryptosporidium in gray Java sparrows in China, which extend the host range for C. baileyi. These results provide baseline information for further studies of molecular epidemiology and control of Cryptosporidium infection in poultry in China.

Abstract
The occurrence and zoonotic potential of Cryptosporidium spp. and Giardia duodenalis isolated from dogs in Chiang Mai, Thailand were determined. Fecal samples were collected from 109 dogs between July and August 2008. Cryptosporidium spp. infection was determined by immunofluorescent assay (IFA), PCR assays that amplify Cryptosporidium heat-shock protein 70 kDa (hsp70), and two PCR assays that amplify a small subunit-ribosomal RNA (SSU-rRNA). Giardiaduodenalis infection was identified using zinc sulfate centrifugal flotation, IFA, and four PCR assays that amplify the Giardia glutamate dehydrogenase (gdh), beta-giardin (bg), and generic and dog-specific assays of triosephosphate isomerase (tpi) genes. Overall prevalence of Cryptosporidium spp. and G.duodenalis was 31.2% and 45.9%, respectively. Sequence analysis of 22 Cryptosporidium-positive samples and 21 Giardia-positive samples revealed the presence of C.canis in 15, and C. parvum in 7, G. duodenalis Assemblage C in 8, D in 11, and mixed of C and D in 2 dogs. Dogs in Chiang Mai were commonly exposed to Cryptosporidium spp. and G. duodenalis. Cryptosporidium parvum can be isolated from the feces of dogs, and all G. duodenalis assemblages were dog-specific. Dogs could be a reservoir for a zoonotic Cryptosporidium infection in humans, but further studies will be required to determine the clinical and zoonotic importance.

Abstract
Abstract
Background
Cryptosporidiosis is a zoonotic disease caused by the important parasitic diarrheal agent Cryptosporidium spp. Cryptosporidiosis occurs in all classes of animals and man with a rapidly expanding host range and increased importance since the occurrence of human immunodeficiency virus/acquired immunodeficiency syndrome in man.
Objectives
To review the global picture of cryptosporidiosis in man and animals with emphasis on prevalence and risk factors.
Methods
Current relevant literature on cryptosporidiosis was reviewed.
Results
Cryptosporidiosis is widely distributed and the risk factors vary from one region to another with hygiene and immune status as important risk factors.
Conclusions
Cryptosporidium spp. associated mortality has not only been reported in immune-compromised patients, but also in immune-competent patients. Yet in many countries not much attention is paid to the control and prevention of this infection in animals and man. The neglect of this disease despite the serious threat it poses to animals, their husbandry, and humans, has led the World Health Organization to list it among globally neglected diseases. To control and prevent this infection more effort needs to be directed at controlling the risk factors of the infection in man and animals.

Abstract
Giardia duodenalis and Cryptosporidium spp. are divergent protozoal intestinal parasites that infect human beings and other animals, including non-human primates. Although long-tailed macaques (Macaca fascicularis) reside in human communities in Thailand, the prevalence of Giardia spp. and Cryptosporidium spp. in these primates has not been previously investigated. The objective of this study was to evaluate long-tailed macaques living near human communities as possible hosts of these intestinal parasites. In 2014, 200 fecal samples were randomly collected from long-tailed macaques living in different areas of Lopburi province, Thailand, and tested with a panel of PCR assays for Giardia spp. and Cryptosporidium spp. G. duodenalis assemblage B was most frequently detected (6%), while assemblage A and an inconclusive assemblage were detected in single samples, for a total G. duodenalis infection rate of 7%. Two samples (1%) tested positive for Cryptosporidium spp., which were both classified as monkey genotypes. No significant associations were found between G. duodenalis infection and sex or location of macaques. This study indicates that long-tailed macaques can carry G. duodenalis and, to a lesser extent, Cryptosporidium spp. monkey genotype. These results warrant education of residents and tourists to limit contact with long-tailed macaques and to take hygienic precautions to mitigate risk of zoonotic and anthroponotic transmission of these parasites between people and macaques.

Public health significance of zoonotic Cryptosporidium species in wildlife: Critical insights into better drinking water management. INTERNATIONAL JOURNAL FOR PARASITOLOGY-PARASITES AND WILDLIFE 2015; 5:88-109. [PMID: 28560163 PMCID: PMC5439462 DOI: 10.1016/j.ijppaw.2015.12.001] [Citation(s) in RCA: 123] [Impact Index Per Article: 13.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/29/2015] [Revised: 12/01/2015] [Accepted: 12/02/2015] [Indexed: 11/22/2022]
Abstract
Cryptosporidium is an enteric parasite that is transmitted via the faecal-oral route, water and food. Humans, wildlife and domestic livestock all potentially contribute Cryptosporidium to surface waters. Human encroachment into natural ecosystems has led to an increase in interactions between humans, domestic animals and wildlife populations. Increasing numbers of zoonotic diseases and spill over/back of zoonotic pathogens is a consequence of this anthropogenic disturbance. Drinking water catchments and water reservoir areas have been at the front line of this conflict as they can be easily contaminated by zoonotic waterborne pathogens. Therefore, the epidemiology of zoonotic species of Cryptosporidium in free-ranging and captive wildlife is of increasing importance. This review focuses on zoonotic Cryptosporidium species reported in global wildlife populations to date, and highlights their significance for public health and the water industry.

Molecular characterization of Cryptosporidium spp. in domestic pigeons (Columba livia domestica) in Guangdong Province, Southern China. Parasitol Res 2015; 114:2237-41. [PMID: 25773186 DOI: 10.1007/s00436-015-4415-1] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2015] [Accepted: 03/03/2015] [Indexed: 10/23/2022]
Abstract
To investigate the prevalence and assess the zoonotic transmission burden of Cryptosporidium species in domestic pigeons in Guangdong Province, Southern China, 244 fecal samples were collected from four pigeon breeding farms between June 2012 and March 2013. Cryptosporidium oocysts were purified by Sheather's sugar flotation technique and characterized by DNA sequencing of small subunit ribosomal RNA (SSU rRNA) gene. Cryptosporidium species were determined by comparison of sequences with corresponding Cryptosporidium sequences in GenBank and phylogenetic analysis using neighbor-joining (NJ) in MEGA5.2. The overall prevalence of Cryptosporidium infection in domestic pigeons in Guangdong Province was 0.82% (2/244). Two Cryptosporidium species, namely Cryptosporidium baileyi and Cryptosporidium meleagridis, were identified in Huizhou and Chaozhou farm, respectively. These findings confirmed the existence of C. meleagridis infection in domestic pigeons in China for the first time and provided base-line information for further studies to evaluate the public health risk from pigeon to human.
