Helmintos e protozoários em fezes de javalis (Sus scrofa scrofa) criados em cativeiro

Abstract

Faecal samples from 79 wild boars (Sus scrofa scrofa) were examined by sedimentation method, zinc sulfate flotation method, and centrifugal flotation in sugar solution for endoparasites research. The results showed that 97.5% of the samples were positive for helminths and/or protozoa as follows: strongilides (70.9%), Ascaris suum (46.9%), Trichuris suis (29.1%), Metastrongylus sp. (12.6%), Strongyloides ransomi (3.8%), Balantidium coli (38.0%), Entamoeba spp. (15.2%), Giardia spp. (1.3%), Blastocystis sp. (12.6%). The frequency of Entamoeba was higher in young animals. Coccidian oocysts were observed in 59.5% samples and five species of Eimeria and one Isospora were recovered: Eimeria scabra (31.9%), E. deblieck (31.9%), E. perminuta (23.4%), E. cerdonis (17.0%), E. scrofae (12.8%) and Isospora suis (12.8%).
