Research was conducted to study the parasite fauna of sheep in the Guba-Khachmaz economic region of Azerbaijan and the species composition of pathogenic parasites causing a decrease in productivity and mortality of animals was determined. The nematode fauna of sheep in the Guba-Khachmaz economic region consisted of 22 species, the trematode fauna consisted of 4, and the cestode fauna consisted of 5 species. Among the primary blood parasites found in sheep are Anaplasma ovis, which belongs to the Rickettsiales order, and Babesia ovis, Theileria ovis, Th.recondita, which belong to the Piroplasmida order. During the study period, 4337 sheep were examined for helminths in the economic region using the complete and incomplete dissection methods. In 3560 of 4337 sheep, was noted associative invasion by nematodes, cestodes and trematodes (I.E. - 82.1%). Infection with nematodes was accompanied by weight loss and a decrease in the quality of wool in sheep, and intensive invasion with fasciola led to the death of young animals, mainly lambs. Intensive infection of sheep with monieziasis was accompanied by a decrease in appetite and milk yield, weight loss. To determine associative ınvasion of sheep with helminths and primary blood parasites, were examined peripheral blood smears and fecal samples from 3435 animals. Of 3435 samples in 1996, were found to have associative invasion with primary blood parasites and helminths (I.E.-58.1%). Mortality has been reported in lambs under 1 year of age, especially 4-5 months old, associated with primary blood parasites and helminth infections. Ectoparasitic ixodid ticks, which transmit primary blood parasites that parasitize animals in the Guba-Khachmaz economic region, are classified into 2 genera, consisting of 4 species.
