capybaras are the largest of living rodents and are the most common wild rodent in the state of rio grande do sul, brazil. they are commercially bred for their meat, hide, and oil. the present study aims to shed some light upon intestinal protozoa of capybaras using sheather's method modified by benbrook to analyze 250 fecal samples. the following eimeria species were detectedooo in 52.4% of the fecal samples: e. trinidadensis, e. ichiloensis, e. boliviensis, in addition to another species that could not be identified. with regard to the total oocyst count, the relative frequency of different eimeria species was as follows: e. trinidadensis (55%), e. ichiloensis (32.6%), e. boliviensis (4.8%), and an unidentified eimeria species (7.6%). the unidentified species was called eimeria araside sp.n.
