Resumo

Background: The rhea (Rhea americana) is a Brazilian wild bird that produce meat, leather and feathers of excellent quality. Rhea production has been increasing every day in Brazil due to many favorable conditions for breeding and there are also large native populations in various regions of the country. The incidence of parasites is a limiting factor when raising many animals, and rheas are not an exception. The occurrence of Cryptosporidium spp in captive rheas in a Brazilian zoo and Spain was described. However, little is known about cryptosporidiosis in rhea, which makes the need for further studies. Thus, this study aimed to detect Cryptosporidium parvum in rheas from the South of Brazil.Case: This study evaluated two properties located in Southern Brazil. Property A was located in Rio Rufi no, Santa Catarina State, Brazil and it had 40 rheas for commercial purposes. Property B was located in Santa Maria, a small town in Rio Grande do Sul State, Brazil and it had 10 rheas. Fresh fecal samples were collected and kept refrigerated from adult birds (n = 4) and chicks (n = 2) from property A, and chicks (n = 3) of three months of age from property B. Samples were analyzed by the method of direct examination, followed by centrifugal flotation with zinc sulfate. Only the centrifugal fl otation technique allowed the observation of Cryptosporidium spp. oocysts in three adults and
