Abstract
The primitive blood parasites - piroplasmids are pathogens transmitted to the agricultural animals by the ticks and caused the death and serious economic damage. In Azerbaijan, in the economic regions where the animal husbandry is developed, the systematic investigation and epizootology of these parasites in small ruminants, were researched by us for the first time. For this purpose, the research work was conducted in the Shirvan-Salyan economic region. For this purpose, researches were conducted on the taxonomic study of primitive blood parasites and their transmitters - Ixodidae ticks of small ruminants in the Shirvan-Salyan economic region. Out of 887 sick and suspected diseases sheep, 483 heads (54.5%), and 125 heads (27.4%) of 456 goats had positive results of peripheral blood smear samples attributed to primitive blood parasites. Babesia ovis and Anaplasma ovis parasites were detected in the erythrocytes of sick sheep, and the infection was mostly associated. A.ovis parasite was detected in sero samples of goats. The organs of 56 sheep and 31 goats that died of high fever - spleen, kidney, liver - were examined for primitive blood parasites. The results of the classical examination method in the diagnosis of A.ovis and B.ovis parasites were compared with the effectiveness of the polymerase chain reaction (PCR). 2,875 sheep and goats (1,786 sheep, 1,089 goats) were examined for ectoparasites in livestock farms, 63.8 percent of sheep and 53.6 percent of goats were intensively infected with ticks. Tick infestation was mostly covered in spring, summer and autumn with high intensity. Rhipicephalus bursa ticks were dominant in sheep and Hyalomma plumbeum ticks in goats. In order to determine transovarial and transstadial transmission of disease agents, smears made from internal organs (salivary gland, ovary, intestine) and eggs of ticks were studied for A.ovis and B.ovis parasites.
