RESUMO
This study was designed to determine the presence and the prevalence of Anaplasma phagocytophilum infection in sheep and cattle in the Middle and Eastern Black Sea Regions of Turkey in which the potential vector, Ixodes ricinus, is widespread. Blood samples were collected from 720 sheep and 720 cattle from 6 provinces of the region, and used for detecting antibodies to A. phagocytophilum by indirect immunofluorescent antibody test (IFAT) and specific nucleic acids by a nested polymerase chain reaction (PCR). Blood smears were also prepared and examined microscopically for the presence of A. phagocytophilum-like organisms in polymorphonuclear cells. Of the animals examined, antibodies were detected in 110 (15.27%) cattle and 107 (14.86%) sheep and A. phagocytophilum-like organisms were detected in the blood of 73 (10.13%) cattle and 71 (9.86%) sheep. In addition, specific DNA was detected in the blood of 27 (14.75%) cattle and 22 (12.35%) sheep. The results obtained constitute the first molecular and serological evidence of A. phagocytophilum infection in sheep and cattle in the Black Sea Region of Turkey.
