Cryptosporidium spp. (Tyzzer, 1907) e Giardia spp. (Leeuwenhoek, 1681) em mamíferos silvestres do estado do Pará, Brasil.

Abstract

Zoonotic enteric parasits have been a huge problem in public health, due to the presence of high and frequent levels of protozoa as Cryptosporidium spp. and Giardia spp. noticed in regions where basic sanitation are precarious, causing outbreaks of diarrhea in human beings, wild and domestic animals. These infective agents are protozoa that present several pathogenic species easily transmited to many types of hosts. The present survey objective was to evaluate the occurrence of Cryptosporidium spp. and Giardia spp. in several species of wild mammals in the State of Pará, Amazonia, Brasil. Samples of feces from 140 indicidual wild animals (six in their natural habitat and 134 raised in captivity) were collected in six different rural municipalities in the State of Pará. The research for Giardia spp. e Cryptosporidium spp., were respectively done through direct and Kinyoun methods besides the routine immunological exams (RIDA®QUICK Cryptosporidium/Giardia/Entamoeba Combi N1722) under the proposal to detect antigens for both parasites. Cryptosporidium spp. was detected in 9,28% (13/140) of the samples, being present in two samples from animals in their natural habitat and 11 in captivity. Giardia spp. was present in 10% (14/140) of the samples, being present in one animal in their natural habitat and 13 raised in captivity. Only one animal was infected by both protozoa at the same time. The results indicate the presence of Cryptosporidium spp. and Giardia spp. in wild mammals in the Amazon region in the State of Pará, possibly taking place as keepers and as disseminators of these infective agents to the environment and to some other hosts, what shows that the real contribution of these mammals on the dissemination and also maintenance of these cited zoonotic infective agents, have not been clearly known.
