The introduction of exotic species can increase the risk of extinction of native species through the introduction of new diseases, predation or resource competition. The marmosets Callithrix penicillata and Callithrix jacchus and hybrids of these two species have been introduced to privately owned forests in the lowland Atlantic forest of the Rio de Janeiro State in Brazil, the region of occurrence of the endangered golden lion tamarin, Leontopithecus rosalia. Because the ecology and biology of the marmosets and tamarins is similar, there is a reasonable risk that the marmosets would transmit pathogens such as endo parasites. The objective of this study was to identify the helminth fauna present in the introduced marmosets through an analysis of fecal samples of wild caught animals, and to evaluate the parasitological profile according to age, sex and geographical location. Eggs belonging to the Acanthocephala and Nematoda were found in the feces. One nematode egg type was identified as being Primasubulura jacchi. The ocurrence of nematodes was higher in males, acanthocephala were found in all age groups and sexes and P. jacchi was found with higher frequency in adult females. The geographic distribution analysis revealed that some of the forests had a higher predominance of parasites. Little is known about the pathology of parasites in free living Neotropical mammals, and this knowledge would be necessary to infer about the risk (form a parasitological standpoint) that the marmoset presence represents for the survival of the endangered golden lion tamarin.
