This research aimed at evaluating the gastrointestinal parasitism by protozoa in monkeys kept in captivity in the Southern region of Brazil. Fecal samples from 18 primates of the species Cebus apella, Macaca mulata, Callithrix jacchus and Callithrix penicillata were analyzed by the zinc sulphate centrifugal flotation method. Simple and mixed infections by protozoa of the genus Cryptosporidium, Giardia, Cystoisospora and Balantidium were observed. The water offered to the primates had elevated presence of oocysts of Cryptosporidium spp.
