Duque de Araujo Munhoz AM, Fernandes EA, Molarinho Marques JD, Berto BP. Remarks on Eimeria spp. (Apicomplexa: Eimeriidae) from Kobus spp. (Bovidae: Reduncini), with supplementary morphological data of Eimeria congolensis Ricci-Bitti et al., 1973 from a new host subspecies, the common waterbuck Kobus ellipsiprymnus ellipsiprymnus (Ogilbyi, 1833). Int J Parasitol Parasites Wildl 2024; 24:100952. [PMID: 38948237 PMCID: PMC11214175 DOI: 10.1016/j.ijppaw.2024.100952] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2024] [Revised: 06/05/2024] [Accepted: 06/05/2024] [Indexed: 07/02/2024]
Abstract
Reduncin bovids of Kobus spp. (Bovidae: Reduncini) are natively distributed in sub-Saharan Africa, although some populations have been introduced into parks and zoos around the world. The majority of the species has declining populations, being categorized as threatened by the International Union for Conservation of Nature and Natural Resources; therefore, protective measures for the conservation of Kobus spp. are necessary, including the study of their parasites, such as the eimeriid coccidians (Apicomplexa: Eimeriidae). In this context, the aim of the current study was to brings together the taxonomic data from the descriptions and reports of Eimeria spp. from reduncin bovids, based on the detailed morphological identification of Eimeria congolensis Ricci-Bitti, Pampiglione & Kabala, 1973 from a new host subspecies, the common waterbuck Kobus ellipsiprymnus ellipsiprymnus (Ogilbyi, 1833), in a safari park of Portugal. Five Eimeria spp. are recorded from reduncin bovids, in addition to six more reports identified generically as Eimeria sp., which were compared and taxonomically rearranged. The oocysts identified as E. congolensis in the current study were compatible with the original description and were supplemented for some taxonomic characters not originally included, such as: Stieda body flattened to nipplelike, sub-Stieda body rounded to trapezoidal, sporocyst residuum granular and membrane-bound, in addition to greater details of the micropyle, among others. Finally, the current study highlights the importance of studying the coccidians of reduncin bovids for the conservation of Kobus spp. due to the possibility of these Eimeria spp. are extra-intestinal parasites, which can potentially cause severe coccidiosis associated with increased morbidity and mortality in certain threatened populations of Kobus spp.

Abstract
Introduction The transmission of pathogens from wildlife to humans is a major global health threat that has been highlighted by the proposed origins of the COVID-19 pandemic. Numerous barriers impede pathogen spillover events from ensuing widespread human transmission, but human activity has accelerated the frequency of spillovers and subsequent disease outbreaks, in part through a booming wildlife trade whose impacts on health are not well understood. Methods A literature review was conducted to examine the risk that the wildlife trade poses to public health and the degree to which these risks are recognized and addressed in clinical practice and medical and veterinary education. Results The illicit aspects of the wildlife trade challenge efforts to understand its impacts on health. The U.S. and Europe play a leading role in the global wildlife trade that often goes unacknowledged. In particular, the consumption of wild meat and ownership of exotic pets poses public health risks. The potential role of clinicians is underutilized, both in the clinical setting and in clinical education. Discussion Physicians and veterinarians have the unique opportunity to utilize their clinical roles to address these knowledge gaps and mitigate future outbreaks. We outline a multifaceted approach that includes increasing clinical knowledge about the ecology of zoonotic diseases, leveraging opportunities for mitigation during patient/client-clinician interactions, and incorporating One Health core competencies into medical and veterinary school curricula.

Wild Animals in Captivity: An Analysis of Parasite Biodiversity and Transmission among Animals at Two Zoological Institutions with Different Typologies. Animals (Basel) 2024; 14:813. [PMID: 38473198 DOI: 10.3390/ani14050813] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2024] [Revised: 03/01/2024] [Accepted: 03/04/2024] [Indexed: 03/14/2024] Open
Abstract
We have conducted a 10-year-long coprological study of the animals housed in two zoological institutions (ZooAquarium and Faunia, Madrid, Spain) to assess the parasite biodiversity, prevalence, and their relation with host class, diet, and enclosure type (soil type and level of isolation from wild fauna). A total of 4476 faecal samples from 132 mammal species and 951 samples from 86 avian species were examined. The results indicated that only 12.8% of avian species had parasites at least once during the study period, whereas 62.1% of mammal species tested positive. Predominantly, protists (Entamoeba, flagellates, and ciliates) and nematodes (mainly Trichuris) were identified in the findings. Carnivorous species were primarily infected by nematodes, while herbivorous and omnivorous species were mainly infected by protists. The number of infected herbivorous and omnivorous species was significantly greater than carnivorous species. Differences were observed based on soil type (artificial, natural, mixed) and isolation level (isolated/accessible), but these differences were not statistically significant. Several parasites (Entamoeba spp., Giardia spp., Balantidoides coli, Trichuris spp.) could potentially be transmitted between humans and some mammals and birds. Regular animal analyses and a personnel health program in the institutions would minimise transmission risks between zoo animals, wildlife, and humans.

Parasit Vectors 2024; 17:94. [PMID: 38419103 PMCID: PMC10900558 DOI: 10.1186/s13071-024-06173-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2023] [Accepted: 01/30/2024] [Indexed: 03/02/2024] Open
Abstract
BACKGROUND Gastrointestinal tract (GIT) nematodes prefer to live in the intestines of wild animals, causing damage and even death, and posing a zoonotic risk. The polyparasitism of GIT nematodes results in the complex dynamics of the nematode communities that occur naturally in wild animals. However, the nematode community in captive wild animals is poorly understood. METHODS We combined microscopic examination and amplicon sequencing for community diversity. RESULTS We characterized GIT nematode assemblages to one order, one family, four genera, and ten species, in 512 fecal samples of 121 species from captive wild animals in southern China. The positive rate of GIT nematodes was 20.7% (106/512), including 42.3% (11/26) in reptiles, 26.5% (39/147) in herbivores, 25.0% (25/100) in non-human primates, 20.0% (5/25) in omnivores, 12.2% (9/74) in carnivores, and 12.1% (17/140) in avians. The dominant nematodes were Haemonchus contortus in herbivores and Trichuris species in primates. The nematode communities of arboreal primates differed from their terrestrial counterparts, reflecting both host phylogeny and ecological constraints. Soil-transmitted Strongyloides species were widespread throughout the herbivore, primate, avian, and carnivore communities, and tended to infect omnivorous primates and terrestrial herbivores. In addition, new Trichuris and Heterakis species were found in the nematode communities of captive porcupines and peafowls. CONCLUSION This study highlights the variation in the composition of the GIT nematode community and strengthens the attention to the harms induced by zoonotic nematodes and co-infective nematodes with low species richness.

[PMID: 38264469 PMCID: PMC10804609 DOI: 10.3389/fvets.2023.1270202] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2023] [Accepted: 12/20/2023] [Indexed: 01/25/2024] Open
Abstract
Non-human primates (NHPs) living in captive conditions are susceptible to intestinal parasites that can contribute to mortality and morbidity, and cause zoonotic infections. Thus, parasite surveys on NHP populations under human care are relevant as part of the evaluation of NHPs welfare and in the zoonotic disease risk assessment, as well as in the exploration of parasite transmission pathways, according to the One-Health concept. This study aimed to identify intestinal parasites infecting NHPs living in two wildlife recovery centers and in a zoological garden, in Italy. Ninety-three fecal samples from Macaca tonkeana, Macaca fascicularis, Sapajus apella, Chlorocebus aethiops, Macaca fuscata, Macaca sylvanus, and Cebus capucinus were collected at Piano dell'Abatino Park (Lazio), and fecal smears and flotation were performed in order to identify parasites according to morphological keys. Additionally, one carcass of M. fuscata from the Bioparco Zoological Garden of Rome (Lazio) and one of M. fascicularis from the Center for the Recovery of Exotic and Maremma Wild Animals (Tuscany) were necropsied and intestinal adult nematodes were collected and characterized at morphological and molecular level, using the mitochondrial cox1 and rrnL markers. Protozoans (Entamoeba coli, Iodamoeba bütschlii, Dientamoeba fragilis-like, Giardia sp.), chromists (Balantidium/Buxtonella sp.) and nematodes (Capillaria sp., Trichuris sp., strongyliform larvae and Oesophagostomum sp.) were found through fecal smears and flotation. The collected adult nematodes from dead NHPs were morphologically identified as whipworms (genus Trichuris). Phylogenetic analyses grouped Trichuris specimens into the Trichuris trichiura complex of species, with specimens from M. fuscata clustering into a host-specific branch, and whipworms from M. fascicularis clustering within a clade formed by Trichuris infecting several primate species, including humans. The results here collected revealed the presence of potentially zoonotic parasites circulating in captive primates in Italy, providing useful information for the formulation of management and care plans for captive NHPs, and for the elaboration of safety measures for visitors and animal keepers.

Abstract
Background and Aim Captive animals are susceptible to parasitic diseases due to the stress and confinement they experience. In addition, they can serve as reservoirs of zoonotic parasites that have the potential to infect humans. To investigate this possibility, we estimated the prevalence of gastrointestinal (GI) parasites in captive mammals at Khon Kaen Zoo, Thailand. Materials and Methods One hundred and forty-seven individual mammals (37 primates, 43 carnivores, 62 herbivores, and 5 rodents) were examined for parasitic infections by fecal examination daily for 3 consecutive days using the formalin-ethyl acetate concentration technique (FECT) and the agar plate culture method. Results According to FECT, the overall prevalence of GI parasites was 62.6% (92/147). Within animal groups, the numbers were as follows: 67.6% (25/37) in primates, 23.3% (10/43) in carnivores, 85.5% (53/62) in herbivores, and 80.0% (4/5) in rodents. Using the agar plate culture method, 21.43% (27/126) were positive for Strongyloides spp. and hookworm infections. The GI parasites identified belonged to three categories: protozoa (including Entamoeba histolytica species complex, Entamoeba coli, Giardia spp., coccidia, and ciliated protozoa), trematodes (minute intestinal flukes and rumen flukes), and nematodes (strongyle/hookworm, Strongyloides spp., Ascarididae, and Trichuris spp.). Conclusion The findings of this study indicate the prevalence of several GI parasites in zoo animals with the potential for transmission to humans, given the animals' close proximity to both visitors and animal caretakers.

Abstract
Zoonotic outbreaks are considered one of the most important threats to public health. Therefore, it is important to educate people on how to prevent zoonotic infections. The purpose of this research was to investigate an intervention aimed at changing people's attitudes and behaviors toward more protective actions. In two studies (NStudy1 = 402; NStudy2 = 706), participants received an intervention based on previous literature in which knowledge about zoonoses, protective actions they could take, and a fear appeal were provided. In the control condition, no intervention was given. Subsequently, we measured participants' risk knowledge, attitudes and behavioral intentions to reduce zoonotic risks, and fear. The results showed that the intervention heightened participants' zoonotic knowledge and affected their attitudes and behavioral intentions (Studies 1 and 2) and a behavioral decision (Study 2) to reduce zoonotic risks. Moreover, our designed intervention proved more effective than the World Health Organization informative message on zoonoses (Study 2). In terms of theory, this is the first experimental demonstration that a general zoonotic risk communication message changed attitudes and behaviors toward more protective actions. In terms of policy, this research showed that a basic information message for the broader public has the potential to reduce zoonotic risks.

Abstract
The hygiene hypothesis, according to which the recent reduction of exposure to infectious agents in the human species would be the origin of various diseases, including autoimmune diseases and cancer, has often been proposed but not properly tested on animals. Here, we evaluated the relevance of this hypothesis to cancer risk in mammals in an original way, namely by using information on zoo mammals. We predicted that a higher richness of parasitic cohorts in the species' natural habitat would result in a greater occurrence of evolutionary mismatch due to the reduction of parasites in captive conditions. This, in turn, could contribute to an increased risk of developing lethal cancers. Using a comparative analysis of 112 mammalian species, we explored the potential relationship between cancer risk and parasite species richness using generalized phylogenetic least squares regressions to relate parasite species richness to cancer risk data. We found no strong evidence that parasite species richness increased cancer risk in zoo mammals for any of the parasite groups we tested. Without constituting definitive proof of the irrelevance of the hygienic hypothesis, our comparative study using zoo mammals does not support it, at least with respect to cancer risks.

Abstract
BACKGROUND Zoological gardens (Zoo) provide abode to various threatened animals or trafficked animals seized by the authorities, and injured and orphaned animals. Captive animals are more susceptible to infection as they are under significant stress due to diet and space which further dwindle their resistance to parasitic infections. OBJECTIVES This study was conducted to determine the prevalence and burden of gastrointestinal parasites in captive mammals housed at Central Zoo. METHODS Fresh faecal samples from three orders of mammals including carnivora (n = 24), rodentia (n = 28) and artiodactyla (n = 35) were examined by direct smear, faecal floatation and sedimentation techniques, and the McMaster technique was applied to quantify parasite eggs per gram (EPG)/oocysts per gram (OPG) of a faecal sample. RESULTS One or more parasite taxa were detected in 19.54% of the examined samples and five types of GIPs including one protozoon (Eimeria spp.) and four helminths (Strongyloides spp., Haemonchus spp. and Trichostrongylus spp. and hookworm) were recorded. The protozoan prevalence (6.89 %) was lower than helminths (12.64%). The Eimeria spp. was the most prevalent parasite (6.89%) with the highest OPG (427.77 ± 25.45SD) in spotted deer (Axis axis), and the highest prevalence was noticed among artiodactyla (34.28%) followed by carnivora (12.5%) and rodentia (7.14%). Artiodactyla had both single infection (25.71%) and double (8.57%) infection. The percentage of single infection (16.09%) was found to be higher than double infection (3.44%) among the captive mammals. The wild boar (Sus scrofa) had the highest EPG of 383.33 ± 76.37SD (Strongyloides spp.), while the spotted deer had the lowest EPG of 216.66 ± 76.37SD (hookworm). CONCLUSIONS Despite careful management practices, the parasitic infection may be attributed to the narrow enclosure, group housing and environmental contamination. The present finding provides baseline information on the parasitic infection in captive mammals, and can be used by zoo managers for the better life of captive animals.

The Prophylactic Effect of Ivermectin Treatments on Nematode Infections of Mammals in a Faunistic Park (Northern Italy). Animals (Basel) 2022; 12:ani12091124. [PMID: 35565548 PMCID: PMC9099513 DOI: 10.3390/ani12091124] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2022] [Revised: 04/25/2022] [Accepted: 04/26/2022] [Indexed: 11/16/2022] Open
Abstract
Nematode infections of mammals can spread in zoos and faunistic parks and lead to disease in humans and animals. Group treatment strategies with anthelminthic drugs are common. Still, their effectiveness should be verified by sensitive and specific copromicroscopic analyses. This study assessed longitudinal parasitological monitoring, by FLOTAC® dual technique, in mammals housed in an Italian faunistic park, in order to verify the effectiveness of the two adopted ivermectin prophylactic treatments. Twenty-one species of herbivorous mammals from ten families were treated twice per year with ivermectin in an in-feed formulation (medicated feed containing 1.7 g/ton ivermectin daily, for 30 days in March and November), while 13 species of carnivores and primates from five families were treated once a month with oral or subcutaneous administrations of ivermectin (200 μg/kg body weight (b.w.), from March to November). Fecal samples were collected in June–July and October 2019 (late spring–early summer and autumn sampling groups, respectively). All nematode infections, sustained by Nematodirus spp., Capillaria spp., Trichuris spp., Parascaris spp. and Strongylida, were detected in samples collected from herbivores, presenting prevalence rates of infection of 17.3% (9/52), 15.4% (8/52), 15.4% (8/52), 5.8% (3/52), and 3.8% (2/52), respectively. All carnivores and primates tested negative. The general linear mixed model showed that nematode eggs’ excretion in herbivores were influenced by sampling and sampling-host family interaction. Results showed that frequency and dose of prophylactic treatments in herbivores should be improved according to host and parasite taxonomic groups. The treatment adopted in carnivores and primates, together with hygienic management, was effective in nematode control.

Prevalence and diversity of gastrointestinal parasites in free-ranging rhesus macaques (Macaca mulatta) in different land gradients of Bangladesh. Am J Primatol 2021; 84:e23345. [PMID: 34783056 DOI: 10.1002/ajp.23345] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2021] [Revised: 09/14/2021] [Accepted: 11/04/2021] [Indexed: 11/08/2022]
Abstract
Rhesus macaques are considered an important reservoir of different gastrointestinal (GI) zoonotic parasites affecting livestock and humans. Loads of GI parasites in the free-ranging rhesus macaques living in close proximity to communities in Bangladesh are still unknown. To estimate the prevalence and diversity of zoonotic GI parasites in rhesus macaques of Bangladesh, a total of 182 freshly voided fecal samples were collected from macaques living in rural (N = 67), peri-urban (N = 57), urban (N = 28), and Safari park (N = 30) between October 2015 and December 2016. All samples were tested by direct smear, sedimentation, flotation, and the McMaster techniques. A total of fourteen different taxa of GI parasites were detected, revealing an overall prevalence of 54.4% (n = 99; 95% confidence interval [CI]: 46.9-61.8). The prevalence of GI parasites was found to be significantly correlated with the mean parasitic taxa per individual in a group (r = 0.90; p = 0.002). The multivariable logistic regression analysis showed that the overall prevalence of GI parasites in macaques was significantly higher in those inhabiting rural areas (62.69%; odds ratio [OR]: 7.22; p = 0.001) and in macaques with interactions with other animals (60.98%; OR: 5.49; p = 0.005). Our results also indicated that the prevalence of Strongyloides spp. and Balantidium coli infections varied significantly between land gradients. Our results also indicate that macaques frequently visit human settlements for food and are found interacting with domestic animals. In conclusion, the high prevalence of zoonotic GI parasite infection in rhesus macaques found in our study may pose a significant public health risk to communities, particularly in rural areas of Bangladesh. Health promotion to at-risk communities focusing on limiting contact with rhesus macaques is necessary to mitigate potential zoonotic transmission.

Occurrence and molecular characterization of Cryptosporidium spp., Giardia duodenalis, Enterocytozoon bieneusi, and Blastocystis sp. in captive wild animals in zoos in Henan, China. BMC Vet Res 2021; 17:332. [PMID: 34663327 PMCID: PMC8522229 DOI: 10.1186/s12917-021-03035-0] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2021] [Accepted: 09/28/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Captive wild animals in zoos infected with Cryptosporidium spp., Giardia duodenalis, Enterocytozoon bieneusi, and Blastocystis sp. can be sources of zoonotic infections and diseases. Therefore, to investigate the distribution of these pathogens in captive wild animals of zoos in Henan, China, a total of 429 fresh fecal samples were collected from six zoos in Henan, China. The infection rates of Cryptosporidium spp., G. duodenalis, E. bieneusi, and Blastocystis sp. were determined by PCR analysis of corresponding loci. Positive results for Cryptosporidium (C. parvum and C. hominis) were subtyped based on the (gp60) gene. RESULTS The overall prevalence was 43.1% (185/429), and the prevalence of Cryptosporidium, Giardia duodenalis, Enterocytozoon bieneusi, and Blastocystis sp. were 2.8% (12/429), 0.5% (2/429), 20.8% (89/429), and 19.1% (82/429), respectively. Five Cryptosporidium species, namely, C. hominis, C. parvum, C. muris, C. andersoni, and C. macropodum, were identified in this study. Cryptosporidium parvum was further subtyped as IIdA19G1. Two Giardia duodenalis assemblages (A and E) were also identified. A total of 20 Enterocytozoon bieneusi genotypes were detected, including 18 known (BEB6, D, HND-1, CD7, SDD1, Henan-IV, KIN-1, CHK1, Peru8, Henan-V, CHG11, CHG-1, CHS9, CHG21, Type-IV, CHC9, CM5, and CHB1) and 2 novel genotypes (CHWD1 and CHPM1). A total of nine subtypes of Blastocystis sp. (ST1, ST2, ST3, ST5, ST6, ST7, ST10, ST13, and ST14) were identified in captive wild animals in zoos in the present study. Cryptosporidium andersoni, nine Enterocytozoon bieneusi genotypes, and five Blastocystis subtypes were here first identified in new hosts. CONCLUSIONS Our study has expanded the host ranges of these four pathogens. The data indicate that animals in zoos can commonly be infected with these four zoonotic pathogens, and animals in zoos are potential sources of zoonotic infections in humans.

Prevalence of intestinal parasites with molecular detection and identification of Giardia duodenalis in fecal samples of mammals, birds and zookeepers at Beni-Suef Zoo, Egypt. J Parasit Dis 2021; 45:695-705. [PMID: 34475651 DOI: 10.1007/s12639-020-01341-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2020] [Accepted: 12/30/2020] [Indexed: 10/22/2022] Open
Abstract
The current study aimed to investigate the prevalence of intestinal parasites from various species of mammals and birds housed in a zoological garden in Beni-Suef province, Egypt. A total of 77 fecal samples were collected from various primates (16), carnivores (7) and herbivores (54). Meanwhile, 123 fecal samples were collected from two Ostrichs (Struthio camelus), five Numida meleagris (Numida meleagris), twoIndian Peafowls (Pavo cristatus), two Emu (Dromaius novaehollandiae) 101 Pigeons (Columba livia domestica) and 11 Swan Goose (Anser sygnoides). In addition, seven stool samples from zookeepers who had been in close contact with animals and birds were examined. Salt flotation and formol ether sedimentation techniques were applied for parasitological examination. Positive samples of Giardia cysts were preserved in alcohol and kept at 4 °C until DNA extraction. Parasitological findings revealed that 48.05% of zoo animals were infected with intestinal parasites; 11.69% were positive with helminths and 27.27% with protozoa, however 9.09% had mixed infection. It was found that 75%, 57.14% and 38.89% of primates, carnivores and herbivores respectively were infected with intestinal parasites. In Primates the most prevalent parasites were Giardia spp. (43.75%) then Entamoeba histolytica/dispar (12.5%), Entamoeba coli (12.5%) and Trichuris spp. (6.25%). For carnivores, Ancylostomatidae had the highest prevalence (42.86%) followed by Spirometra spp. (14.29%). Meanwhile, Eimeria spp. (20.37%) was the most prevalent parasite in herbivores, followed by Blantidium coli (7.41%) and Tricuris spp. (7.41%), then Toxocara spp. (3.70%). Furthermore, the prevalence of infection in zoo birds was 21.95%. The identified parasites were Eimeria spp., Giardia spp., Capillaria spp., Ascaridia spp., Isospora spp. and Sublura brumpti. Stool examination of zookeepers revealed the presence of G. doudenalis and E. histolytica/ dispar cysts. The gdh gene of G. duodenalis was successfully amplified from fecal samples of zoo mammalsand zookeepers. In conclusion, the application of preventive and control measures against the propagation of infectious intestinal parasites is essential to prevent the spread of these parasites among zoo animals or to humans.

Abstract
Introducción. Los enteroparásitos pueden generar problemas en animales bajo cuidado humano en zoológicos y centros de acogida. Los animales silvestres presentan bajas cargas parasitarias, pero estas pueden ser mayores y llevar a manifestaciones clínicas cuando se trata de animales resguardados en recintos, lo que aumenta los gastos en tratamientos y cuidados médicos. Por otro lado, algunos enteroparásitos pueden causar infecciones zoonóticas en los cuidadores, los visitantes y otros animales del zoológico, así como afectar los programas de recuperación de especies amenazadas de extinción. Objetivos. Determinar la presencia y prevalencia de enteroparásitos con potencial de transmisión zoonótica en primates de las familias Cebidae y Callitrichidae del Zoológico de Cali, entre septiembre y noviembre de 2017. Materiales y métodos. Se hizo un estudio transversal prospectivo, para lo cual se recolectaron muestras seriadas de 50 individuos pertenecientes a siete especies de dos familias de primates y se analizaron mediante examen coprológico, flotación y coloración Kinyoun, entre septiembre y noviembre de 2017. Resultados. Según su prevalencia, los géneros de parásitos hallados en las siete especies de primates evaluadas, fueron Blastocystis spp., Trichomonas spp., Giardia spp., Entamoeba spp., Strongyloides spp., Cyclospora sp. y Trichuris sp. Conclusiones. Por lo menos, seis de los géneros de parásitos identificados tienen implicaciones zoonóticas, lo cual hace necesario establecer las posibles vías de infección de los primates del Zoológico de Cali e implementar protocolos de manejo que reduzcan el riesgo de transmisión a los humanos y a otros animales de la colección. Además, se presenta la información relevante sobre el potencial zoonótico de los enteroparásitos hallados.

Abstract
This study was conducted from November 2010 to June 2011 to determine the prevalence of gastrointestinal parasites and the seroprevalence of Toxoplasma gondii in captive ocelots (Leopardus pardalis) in Trinidad. Faecal samples were collected and analyzed using faecal flotation to identify helminth ova and protozoan cysts and oocysts. Serum samples from captive ocelots were screened for T. gondii using a latex agglutination test kit. Of the 19 ocelots examined, the most prevalent parasites noted were ova of ascarids, strongyles, and Capillaria spp. The serum of three of the 13 (23.1%) ocelots tested was positive for T. gondii antibodies. These ocelots are therefore a potential source of T. gondii infection to both humans and other animals. This is the first documented report of endoparasites in local captive ocelots within Trinidad and provides useful data to support further research of the captive and wild populations.

Abstract
Avian malaria parasites are widespread parasites transmitted by Culicidae insects belonging to different genera. Even though several studies have been conducted recently, there is still a lack of information about potential vectors of Plasmodium parasites, especially in Neotropical regions. Former studies with free-living and captive animals in São Paulo Zoo showed the presence of several Plasmodium and Haemoproteus species. In 2015, a pilot study was conducted at the zoo to collect mosquitoes in order to find out (i) which species of Culicidae are present in the study area, (ii) what are their blood meal sources, and (iii) to which Plasmodium species might they be potential vectors. Mosquitoes were morphologically and molecularly identified. Blood meal source and haemosporidian DNA were identified using molecular protocols. A total of 25 Culicidae species were identified, and 6 of them were positive for Plasmodium/Haemoproteus DNA. Ten mosquito species had their source of blood meal identified, which were mainly birds, including some species that were positive for haemosporidian parasites in the former study mentioned. This study allowed us to expand the list of potential vectors of avian malaria parasites and to improve our knowledge of the evolutionary and ecological relationships between the highly diverse communities of birds, parasites, and vectors present at São Paulo Zoo.

Abstract
Although parrot species are infrequently infected by hemoparasites in the wild, some fatal infections have been reported in captive individuals. Conversely birds of prey are frequently infected by hemoparasites. In this study, 193 captive birds from Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) centers in Madrid, Spain, belonging to orders Psittaciformes, Accipitriformes, Strigiformes, and Falconiformes, were blood-sampled in search of parasite infections. Molecular and microscopic analyses were conducted to detect parasites of the following genera: Haemoproteus, Plasmodium, Leucocytozoon, Trypanosoma, Babesia, and Lankesterella. Infections by microfilariae and Coccidia were also searched in blood samples. Surprisingly, infections by Haemoproteus syrnii, a common parasite from owls, were detected in the cadavers of two species of parrots, Trichoglossus haematodus and Psittacula cyanocephala. The same haplotype was also detected in the cadavers of two owl species, Tyto alba and Strix rufipes. All these birds were housed and died in the same center. Infections by species of Plasmodium, Leucocytozoon, and Trypanosoma were also found in different species of raptors. Nocturnal raptors (Strigiformes) show significantly higher prevalence of infection by blood parasites than diurnal raptors (Falconiformes and Accipitriformes). In conclusion, a potential fatal transmission of Haemoproteus syrnii, from Strigiformes to Psittaciformes species, is reported and several infections by different blood parasites were detected in birds of prey. These results emphasize the importance of increasing prevention measures to avoid or reduce the transmission of blood parasites among birds from different species housed in these types of centers.

Abstract
Monoxenous parasites may easily infect animals in captivity, and nematodes belonging to the genus Trichuris are commonly reported in zoological gardens worldwide. Infections in captive animals should be accurately monitored and the characterization of pathogens is highly advisable, as a tool to infer possible routes of intra- and interspecific transmission pathways and to assess the related zoonotic potential. Whipworms are usually identified on the basis of few morphological features of adults males and eggs and by an host-affiliation criterion. Given the strong morphological convergence of adaptive traits and the possible occurrence of hybridization and/or cross-infections events, the use of molecular methods is of great utility. Here, we analysed two partial mitochondrial loci, the cytochrome c oxidase I and the cytochrome b regions, in Trichuris spp. infecting four animal species hosted in the Bioparco Zoological Garden of Rome. Results from molecular systematics, compared to previous data, suggested that the five Trichuris taxa recovered were well separated, showing a significant degree of host affiliation (herbivorous, primates/swine and rodents/canids). The screw horn antelopes and the camels were infected with two variants of Trichuris ovis; Trichuris sp. similar to those observed in rodents from South America was infecting the Patagonian maras. Moreover, Trichuris from the ring-tailed lemur showed a great similarity to Trichuris infecting the Japanese macaque previously analysed from the same zoological garden, and clustering together with Trichuris trichiura, posing a potential zoonotic threat for visitors and workers.

Oliveira-Arbex AP, David ÉB, Tenório MDS, Cicchi PJP, Patti M, Coradi ST, Lucheis SB, Jim J, Guimarães S. Diversity of Blastocystis subtypes in wild mammals from a zoo and two conservation units in southeastern Brazil. INFECTION GENETICS AND EVOLUTION 2019; 78:104053. [PMID: 31683006 DOI: 10.1016/j.meegid.2019.104053] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/24/2019] [Revised: 09/23/2019] [Accepted: 09/26/2019] [Indexed: 10/25/2022]
Abstract
The enteric protist Blastocystis is one of the most commonly parasite reported in humans and a variety of animal hosts worldwide. Regarding genetic diversity, at least 17 subtypes (STs) have been identified in mammals and birds, with eight of them (ST1-8) infecting both humans and animals. Recently, isolates from wild mammalian species have been genetically characterized, however data is still scarce, mainly in Latin America. Here, we aimed to verify the occurrence and genetic diversity of Blastocystis in captive wild mammals kept in one zoo and in two units of protection and conservation in southeastern Brazil. A total of 78 fecal samples (14 pooled and 64 individual samples) were recovered from 102 wild mammals of 35 species included in the following orders: Primates, Carnivora, Artiodactyla, Pilosa, Rodentia and Marsupialia. Zoo and units staff were invited to participated but only 16 fecal samples could be screened. Based on the sequence analyses of SSUrDNA gene, out of 29 PCR products from animal samples, 51.7% (15/29) were successfully sequenced and five Blastocystis subtypes were identified as follows: ST1 (2/15; 13.3%), ST2 (2/15; 13.3%), ST3 (4/15; 26.6%), ST5 (2/15; 13.3%) and ST8 (5/14; 33.3%). Only four isolates from humans were sequenced and identified as ST1 (2 isolates), ST2 and ST3. It was observed that Blastocystis infecting non-human primates belong to ST1 and ST2 and mainly to ST3 and ST8, artiodactyls ST5, carnivores ST1 and ST5 and rodents ST1. In addition, this present study reports some interesting findings: (1) 63% (12/19) of Blastocystis isolates from animals and employees belonged to the potentially zoonotic subtypes ST1-ST3; (2) most of these isolates displayed high identity with publicly available DNA sequences from non-human primates and humans, including primate handlers; (3) Blastocystis ST5 was found infecting the northern tiger cat, a native South American felid and one of the species facing a high risk of extinction in Brazil.

Abstract
The necropsy of a leopard (Panthera pardus), succumbed to a chronic ailment exhibited a mixed parasitic gastroenteritis. Gross internal examination of carcass revealed the presence of round and tapeworms in the stomach and intestines with diffuse catarrhal and hemorrhagic gastroenteritis. The detailed examination of the intestinal content revealed the presence of Toxocara canis and Spirometra species eggs. Also, the gross morphological investigation of round and tapeworms approved the presence of both species. Histo-pathological examination showed sloughing of intestinal epithelium, hemorrhages, and ulcerative areas with the infiltration of polymorphonuclear cells admixed with mononuclear cells. Lungs revealed the accumulation of eosinophilic edematous fl uid in the alveolar spaces along with inflammatory cells. These parasites are pathogenic to precious wild felids and often pose a threat of zoonotic transmission due to spill-over infections. The present case study is an attempt to put on record a case of parasitic gastroenteritis in a captive leopard.

Abstract
Intestinal parasitic infections can have an impact on health and growth of wildlife. The current study aims were to determine the prevalence of intestinal parasites and to molecular characterize Giardia duodenalis and Cryptosporidium spp. in captive gibbons at Krabokkoo Wildlife Breeding Center, Thailand. Fifty-five gibbons, 2 agile- (Hylobates agilis), 38 lar- (Hylobates lar) and 15 pileated gibbons (Hylobates pileatus) were included in this study. Fecal samples were collected individually at Krabokkoo Wildlife Breeding Center, Chachoengsao province, eastern Thailand, in November 2013. Intestinal parasitic infections were examined by zinc sulfate centrifugation flotation and by a commercially available immunofluorescent assay (IFA) for detection of G. duodenalis and Cryptosporidium spp.. Polymerase chain reaction targeting the Giardia glutamate dehydrogenase (gdh), beta- giardin (bg), triose phosphate isomerase (tpi) genes, and the Cryptosporidium small subunit-rRNA and heat-shock protein (hsp70) following by DNA sequencing were performed on the IFA positive samples. The overall prevalence of intestinal parasitic infection in gibbons at Krabokkoo Wildlife Breeding Center was 12.7% (95%CI: 5.3–24.5), Strongyloides spp. eggs or larvae were present in all positive samples. Co-infections with G. duodenalis were detected in 1.8% (95%CI: 0.1–9.7) of the samples. Based on the sequencing results of the three genes, the IFA Giardia positive isolate typed as the zoonotic genotype B. Since the data reveals the occurrence of zoonotic Giardia genotype, good hygiene management is suggested to prevent the transmission of this pathogen from gibbon to human, and vice versa.

Abstract
Studies on parasites infecting non-human primates are essential to better understand the potential threat to humans of zoonoses transmission, particularly under the current processes of pervasive land use change and biodiversity loss. The natural ecosystems in the Middle Magdalena river basin in Colombia have suffered a dramatic reduction and transformation into pastures and agroindustrial monocultures, threatening their biodiversity, and probably affecting the dynamics between parasites and their hosts, as well as altering the disease transmission cycles between wild populations and humans. This study evaluated seasonality, prevalence and richness of intestinal parasites in three species of neotropical primates: Cebus versicolor, Ateles hybridus and Alouatta seniculus, in a fragmented forest in the Middle Magdalena river valley, Colombia. One hundred and eighty five faecal samples were collected between 2010 and 2015. Direct faecal smears were performed with saline solution (0.85%) and iodine solution (1%), in order to identify larvae and eggs based on their morphology. A large proportion of the samples examined (72.9%) was positive for intestinal parasites; seven families of nematodes were identified: Trichuridae, Trichostrongylidae, Oxyuridae, Strongyloididae, Ancylostomatidae, Ascarididae and Gnathostomatidae, two of protozoans: Entamoebidae and Balantiididae, as well as some eggs of trematodes, cestodes and acanthocephalans. Additionally, DNA extraction and sequencing were conducted on 30 faecal samples in order to identify Giardia sp. and Blastocystis hominis, two parasite species also present in humans. Molecular testing for Giardia sp. was negative and Blastocystis hominis was identified in a single sample of Alouatta seniculus. No clear patterns were observed for prevalence of intestinal parasites according to the season; nonetheless, parasite species richness was higher during the dry season. This study builds on our current understanding of intestinal parasites infecting wild neotropical primates and provides novel information on the patterns of intestinal parasites in primate communities exposed to anthropogenic disturbance.

Abstract
Red pandas are known to be highly susceptible to endoparasites, which can have a prominent impact on the population dynamics of this endangered species. There are very limited published reports on prevalence and risk of parasites in wild populations of red panda, especially localized reports. This study attempts to provide an in-depth insight of the status of endoparasites in red pandas, which is critical for strengthening conservation efforts. A total of 272 fecal samples were collected through systematic sampling across the red panda distribution range in Nepal and coprological examination was completed using standard techniques. It was followed by an estimation of prevalence and mean intensity of parasites, as well as statistical analysis, which was carried out using R statistical software. Parasite prevalence was documented in 90.80% (n = 247) out of 272 samples examined which includes seven different species along with three genera of parasites belonging to Protozoans (3 species), Cestodes (1 genus, 1 species) and Nematodes (2 genera, 3 species). Nematodes predominated in all infected samples (87.62%). Prevalence of Ancyclostoma duodenale (n = 227, 70.06%), having a mean intensity of 3.45 ± 2.88 individuals per sample, was observed, followed by Ascaris lumbricoides (n = 19, 5.86%) and Entamoeba histolytica (n = 24, 7.41%). Eight variables for assessing the determinants of infestation were tested: protected areas; non-protected areas; aspect; elevation; slope; and distance to water sources, herding stations, and settlements. Only the settlement displayed significant association (β = −1534e−04, t = − 2.192, p = 0.0293) though each parasite species displayed dissimilar association with different variables. This study indicates the urgent need of improving existing herding practice through habitat zonation, rotational grazing, medication of livestock, and prohibition of open defecation within and around red panda habitat.

Abstract
BACKGROUND The role of zoos in conservation programmes has increased significantly in last decades, and the health of captive animals is essential to guarantee success of such programmes. However, zoo birds suffer from parasitic infections, which often are caused by malaria parasites and related haemosporidians. Studies determining the occurrence and diversity of these parasites, aiming better understanding infection influence on fitness of captive birds, are limited. METHODS In 2011-2015, the prevalence and diversity of Plasmodium spp. and Haemoproteus spp. was examined in blood samples of 677 captive birds from the São Paulo Zoo, the largest zoo in Latin America. Molecular and microscopic diagnostic methods were used in parallel to detect and identify these infections. RESULTS The overall prevalence of haemosporidians was 12.6%. Parasites were mostly detected by the molecular diagnosis, indicating that many birds harbour subclinical or abortive infections. In this project, birds of 17 orders (almost half of all the orders currently accepted in taxonomy of birds), 29 families, and 122 species, were tested, detecting positive individuals in 27% of bird species. Birds from the Anatidae were the most prevalently infected (64.7% of all infected animals). In all, infections with parasites of the genus Plasmodium (overall prevalence 97.6%) predominated when compared to those of the genus Haemoproteus (2.4%). In total, 14 cytochrome b (cytb) lineages of Plasmodium spp. and 2 cytb lineages of Haemoproteus spp. were recorded. Eight lineages were new. One of the reported lineages was broad generalist while others were reported in single or a few species of birds. Molecular characterization of Haemoproteus ortalidum was developed. CONCLUSION This study shows that many species of birds are at risk in captivity. It is difficult to stop haemosporidian parasite transmission in zoos, but is possible to reduce the infection rate by treating the infected animals or/and while keeping them in facilities free from mosquitoes. Protocols of quarantine should be implemented whenever an animal is transferred between bird maintaining institutions. This is the first survey of haemosporidians in captive birds from different orders maintained in zoos. It is worth emphasizing the necessity of applying practices to control these parasites in management and husbandry of animals in captivity.

Abstract
Summary
Ramphastidae (Aves: Piciformes) are animals recognized for their exuberant colours and long bill, with distribution range from south Mexico to north Argentina. They are important seed dispersers eating little vertebrates eventually. When in captivity, animals usually live in limited spaces, with high density and near by species that do not share a evolution history, facilitating the occurrence of infectious diseases for what they may not have a competent immune system against, including the parasitic ones. This study analyzed the endoparasites that occur in captive Ramphastidae at São Paulo Zoo in the period January 2009 to September 2011. Seven species of toucans and toucanets had parasitological results positive for Trichuridae nematodes, Eimeria sp., Giardia sp., non sporulated coccidian oocists and unidentified nematode eggs, and microfilarie was the only hemoparasite found.

Abstract
Captive primates are susceptible to gastrointestinal (GIT) parasitic infections, which are often zoonotic and can contribute to morbidity and mortality. Fecal samples were examined by the means of direct smear, fecal flotation, fecal sedimentation, and fecal cultures. Of 26.51% (317/1196) of the captive primates were diagnosed gastrointestinal parasitic infections. Trichuris spp. were the most predominant in the primates, while Entamoeba spp. were the most prevalent in Old World monkeys (P < 0.05). These preliminary data will improve the management of captive primates and the safety of animal keepers and visitors.
