Fauna helmintológica de bovinos da região de Jaboticabal, Estado de São Paulo, Brasil

Abstract

This paper deals with the study of parasites in cattle in the region of Jaboticabal, São Paulo. For this, 42 holstein-zebu mixed breeding animals, 8 to 14 month old, were necropsied. At necropsy 17 species of helminth were collected. The prevalence and intensity of infection were as follow: Haemonchus placei 97,62% (1961,81); Cooperia punctata 92,86% (8109,45); Oesophagostomum radiatum 73,81% (217,38); Trichuris discolor 38,19% (25,48); Trichostrongylus axei 26,19% (122,05); H. simillis 21,43% (37, 45); C. pectinata 19,05% (198,6); Bunostomum phlebotomum 16,66% (8,95); Dictyocaulus viviparus 16,66% (3,62); C. spatulata14,29% (109,95); Capillaria bovis 11,90% (5,48); Ostertagia ostertagi 7,14% (0,86); O. lyrata 4,76% (0,17); Eurytrema coelomaticum 4,76% (2,14); Moniezia benedeni, 4.76% (0,05); T. colubriformis 2,38% (0,48); Strongyloides papillosus 2,38% (0,25). Each calf had an average worm burden of 10804 helminths Haemonchus (18,5%) and Cooperia (77,91%) were the most frequently observed helminths. Mixed infections were commonly observed, 71,43% of the animals were parasitized with three to five different species of helminths. Only 2,38% of the calves were parasitized with ten different species of helminths.
