“…To support their development and well-being, control of parasitic diseases is necessary. Also, the knowledge about parasitic diseases is still considered unsatisfactory, although the number of researches in this field has increased over the last years (Soares et al 2000). The objective of this study was to evaluate the parasitic infection in captive birds, mammals, and reptiles from the "Universidade de Caxias do Sul" (UCS) Zoo, located at Rio Grande do Sul state, Brazil, as well as rescued animals submitted to treatment in the same period.…”

Free-living wild animals can host a wide variety of endoparasites. When subjected to conditions of captivity, these animals can go through stressful situations and develop parasites. Therefore, the objective of this study was to identify parasitic infection in wild mammals, birds, and reptiles kept at the “Universidade de Caxias do Sul” Zoo, in Rio Grande do Sul state, Brazil. The population studied was based on 76 animals, divided into 50% (38/76) birds, 35.53% (27/76) mammals, and 14.47% (11/76) reptiles distributed in 33 different enclosures. Fecal samples were collected from the enclosures and analyzed in triplicate, using the centrifugal-flotation method with a zinc sulfate solution. Samples from the enclosures 31, 32, 33, (where snakes are located), and 15 (animal death), were not analyzed in triplicate, so the total number of analyses was 91 samples. The results showed that 41.76% (38/91) of the samples were positive for at least one class of endoparasites, such as Nematoda, Cestoda, or Coccidia. The positive samples showed the presence of at least one or more parasites from orders Strongylida (34.21%), Enoplida and Strongylida (23.68%), Enoplida only (23.68%), Cyclophyllidea and Oxyurida (5.26%), Ascaridida only (5.26%), Enoplida, Strongylida, and Ascaridida (5.26%), and Enoplida and Eucoccidiorida (2.63%). Considering the positive samples, 55.26% were collected from birds, 39.47% from mammals, and 5.27% from reptiles. Capillaria sp. eggs were the main structure found in birds, and eggs from the order Strongylida were the most found in samples from mammals. This study showed the order Strongylida as the most frequent parasite found in 63.16% of the total samples, established either in isolated or mixed infestations. Also, mammals and birds were those with a greater quantity of positive samples for endoparasites. Therefore, this study emphasizes the importance of carrying out research assessing the gastrointestinal parasitic fauna in wild animals, so one can determine the conditions under which these parasites become pathogenic to wild animals raised in captivity.

Sloths may serve as host to a wide range of parasites. However, there is little information available on the types of parasites that affect Costa Rica's sloth population. During a 1-yr period, 65 specimens of Costa Rican sloth species (Choloepus hoffmanni; n = 56) and Bradypus variegates; n = 9) from a local zoo were sampled. Fecal samples were evaluated using two different diagnostic techniques, Sheather's flotation and sedimentation. Concurrently, these sloths were examined for ectoparasites. Gastrointestinal parasites were found in 14 sloths (21.5%), from which 13 animals were C. hoffmanni and one was B. variegatus. Gastrointestinal parasites were recognized as Coccidia 71.4% (10/14), Cestoda 21.4% (3/14), and Spiruroidea 7.1% (1/14). Coccidia and cestodes were seen in C. hoffmanni, and spirurids were identified in B. variegatus. Among 27 sloths examined, only six had dermal problems (five C. hoffmanni and two B. variegatus). Ectoparasites recovered were Sarcoptes scabiei (Acari, Sarcoptidae) mites and Amblyomma varium (Acari, Ixodidae) ticks. This is the first time that cestode strobilae and nematode eggs are reported in sloth feces and that Monezia benedeni and L. leptocephalus were found in captive sloths.
