The aim of this work was to identify the parasites present in feces of pigs created rustically, as well as, verify the possibility of the morphological differences between the oocysts of the genus Eimeria recovered and, the frequency of these and of other endoparasites considering the age and sex of the animals. Eighteen samples of feces were collected directly from the rectum of animals from the 13 properties located in Municipality of Rio Claro, in the South Fluminense Para?ba Valley in the State of Rio de Janeiro. After the sporulation process of the positive samples, the oocysts could be observed and identified. In the current study, was possible to observe that despite of the animals are created rustically, these presented a low infection percentage. Helminthes eggs were present in 41,25 % of the examined samples being that eggs of the Strongylidae family present in 35% of the samples and were observed with a bigger frequency in young animals (27,5 %) being less frequent in the adults (7,5 %); Trichuris suis eggs were found only in young animals (3,75 %); Ascaris suum eggs in one young animal (1,25 %) and one animal was positive for eggs of the Strongylida order (1,25 %). Fifty-four percent (54 %) of the samples was positive for the species of the genus Eimeria, 46,25 % for Cryptosporidium spp. and 6,25 % for Cystoisospora suis. The species of the genus Eimeria founded and characterized in this study were confirmed through the use of histograms, as being: E. debliecki, E. neodebliecki, E. polita, E. suis, E. porci and E. scabra. It was observed, that the young animals presented bigger infection percentage. The characteristics observed in this study, in the oocysts and sporocysts, was better detailed microscopically revealing structures not observed previously by other authors, as well as, few have been the works concerning to infection for endoparasites in swines in Brazil, principally the works correlating your frequency and epidemiology.
