The first and only study on gastrointestinal parasites of wild rodents in the Island of Santa Catarina was done in 1987. The aim of this study was to identify intestinal parasites from wild rodents in Santo Amaro da Imperatriz and Santa Catariana Island, and to compare the richness and composition of the gastrointestinal parasite community of both areas. Rodents were captured with live traps, and feces were screened using the sedimentation method and optical microscopy. The following species of rodents were captured in the two areas: Akodon montensis, Euryoryzomys russatus, Oligoryzomys nigripes and Nectomys squamipes. In Santo Amaro da Impetratriz, prevalent parasites were: A. montensis (51%), E. russatus (62%), O. nigripes (53%) and N. squamipes (20%). From the Island of Santa Catarina the rodent prevalence rates were: A. montensis (43%), E. russatus (59%), O. nigripes (30%) and N. squamipes (33%) and the collected parasites were: Hymenolepis sp., Longistriata sp., Strongyloides sp., Hassalstrongylus sp., Syphacia sp., Trichomonas sp., Ancylostomidae, Trichuridae, Oxyuridae and Eucoccidiorida. The species richness (10.6 ± 0.7) of the endoparasite comunity in the area located on the continent was higher (p < 0.01) and different (p = 0.001) from that of the area located on the island (6.9 ± 0.5). , Syphacia sp., Trychomonas sp., Ancilostomatidae,Trichuridae, Oxyuridae e Eucoccidiorida. Foi possível observar que os roedores da área localizada no continente (Santo Amaro da Imperatriz) possuem uma comunidade de parasitas gastrointestinais mais rica (10.6 ± 0.7; p < 0.01) e diversa (p = 0.001) do que a comunidade presente na Ilha de Santa Catarina (6.9 ± 0.5).

Article historyZoonotic enteroparasitosis represent an important public health problem, and species of protozoa such as Cryptosporidium spp. and Giardia spp. can reach high frequencies in regions where basic sanitation conditions are poor, which promotes outbreaks of diarrhea in humans and domestic and wild animals. Wild mammals such as the South American coati (Nasua nasua) feed on insects present in the soil, fruits, and small vertebrates, and are susceptible to contamination by enteroparasites present in the environmental niche. The aim of the present study was to investigate the occurrence of Cryptosporidium spp. and Giardia spp. in N. nasua from a region in the Brazilian Amazon. Fecal samples of 27 coatis two from free-living and 25 from captivity were collected in three different municipalities in the state of Pará, Brazil. The search for Giardia spp. and Cryptosporidium spp. in the collected samples were performed using the direct and Kinyoun methods, respectively, and a commercial immunological test (RIDA®QUICK Cryptosporidium/Giardia Combi. ®R-Biopharm) was used to detect antigens from both parasites. Cryptosporidium spp. oocysts were found in 11.1% (3/27) of the samples; one from a free-living animal and two from captive animals. Giardia spp. cysts were found in 11.1% (3/27) of the samples, all from captive animals. This is the first report of infection by these protozoans in this coati's species in the North region of Brazil; the South American coati may be participating as maintainers and disseminators of infectious agents to the environment and other hosts.

“…CHALMERS et al (1997) detectaram prevalências de 22%, 21% e 13% para C. parvum em Mus domesticus, Apodemus sylvaticus e Clethrionomys glareolus e de 10%, 6% e 2%, respectivamente, para C. muris, nessas mesmas espécies animais. DALL´OLIO & FRANCO (2004) encontraram 16,25% de prevalência para Cryptosporidium em roedores e marsupiais em áreas de mata atlântica, no Sudeste do Brasil, sendo C. muris menos frequente que C. parvum.…”

“…Neste estudo, a prevalência de C. muris em roedores silvestres foi semelhante à encontrada por CHALMERS et al (1997). Diferentemente desses autores e de DALL´OLIO & FRANCO (2004), não foram encontrados oocistos com medidas compatíveis com as de C. parvum. A ausência Ciência Rural, v.39, n.5, ago, 2009.…”
