GASTROINTESTINAL PARASITES IN GOATS AND SHEEPS FROM ALTO MEARIM AND GRAJAU MICROREGION, STATE OF MARANHAO, BRAZIL The objective of this work was to know the gastrointestinal nematodes and to verify the presence of Eimeria spp. in goats and sheeps of Alto Mearim and Grajau microregion, Maranhao State. 384 animals (192 goats and 192 sheeps) from the municipalities of Formosa da Serra Negra, Grajau and Sitio Novo were sampled. Fecal samples from male and female aged more than one year were collected in the dry and rainy periods. The samples were processed for OPG and OoPG by McMaster technique and larvae culture. From the goats sampled, 176 (91.66%) were positive for helminthes eggs and in 134 (69.79%) oocysts of Eimeria were detected. In sheeps, 122 (63.54%) had helminthes eggs and 133 (58.85%) had oocysts of Eimeria. Eggs of Strongyloidea, Strongyloides 968 BRITO, D. R. B. et al. Ciencia Animal Brasileira, v. 10, n. 3, p. 967-974, jul./set. 2009 and Moniezia were identified. The following genera were identified in goats: Haemonchus (35.41%), Trichostrongylus (27.29%), Cooperia (23.61%), Oesophagostomum (8.93%) and Stronyloides (4.75%) and in sheeps Haemonchus (30.21%), Trichostrongylus (25.29%), Cooperia (24.28%), Oesophagostomum (14.12%) and Stronyloides (6.09%). The animals displayed greater parasitism in the rainy period being more evident in males than in females. The genera Haemonchus, Trichostrongylus, Cooperia and Eimeria were the predominant ones in goat and sheep in the Alto Mearim and Grajau microregion, Maranhao.
