Piroplasms of domestic animals in the Macedonia region of Greece 2. Piroplasms of cattle

Abstract

A study was carried out on piroplasms of cattle in the Macedonia region of Greece. During 1984–1986, 602 serum samples were collected from cattle in 33 localities. Blood smears were also prepared from 50 of the animals in 13 localities. The indirect fluorescent antibody (IFA) test revealed that 41.4% of cattle sera were positive to Theileria orientalis, 2.0% to Theileria annulata, 21.6% to Babesia bovis, 15.2% to Babesia bigemina, 5.1% to Babesia major and 2.7% to Babesia divergens. Some of the positive titres were probably due to cross reactions. T. orientalis was widely distributed. T. annulata was limited to a small number of foci. B. bigemina and B. bovis, often present together, were widespread, whereas B. major was only present in a small number of localities. No convincing evidence of B. divergens infection was found. By examination of Giemsa stained blood smears T. orientalis, T. annulata and a Babesia sp. were detected.
