Abstract

The objective of this study was to detect helminth eggs and protozoan oocysts in samples of feces from birds of the order Passeriformes in Para State, Brazil. Fecal samples were collected individually from 403 passerine birds seized and kept in captivity in Para State. Samples were processed by the double centrifugation technique in saturated sucrose solution and the coccidial oocystpositive samples were submitted to sporulation in potassium dichromate 2.0%. Helminth eggs and/or protozoan oocysts were observed in 43.18% (174/403) of the fecal samples examined. Coccidial oocysts were detected in 93.68% (163/174) of the positive samples, whereas helminth eggs were observed in 10.34% (18/174) of the positive samples. Oocyst sporulation occurred in 43.56% (71/163) of the samples, and only Isospora spp. oocysts were detected. Nematode eggs of the superfamilies Trichostrongyloidea (4.60%; 8/174), Ascaridoidea (0.57%; 1/174), and Trichuroidea (0.57%; 1/174) were diagnosed in the positive samples. Cestoda eggs were diagnosed in 2.87% (5/174), whereas Trematoda eggs were detected in 2.30% (4/174) of positive samples. Passerine birds seized and kept in captivity in the visited local presented parasitism by intestinal helminths and protozoan, with a predominance of infection with coccidia of the gender Isospora.
