Abstract
A study was carried out on piroplasms of small ruminants in the Macedonia region of Greece. During 1984–1985, 721 serum samples were collected from sheep in 49 localities and 487 from goats in 43 localities. Blood smears were also prepared from 26 sheep and eight goats in 16 localities. The prevalence of positive IFA titres for sheep and goat sera, respectively, was: 24.6% and 0.6% for Theileria ovis, 52.1% and 36.4% for Babesia ovis, 10.5% and 4.2% for Babesia motasi, 12.6% and 6.6% for Babesia crassa. Many of the positive reactions, specially for the large Babesia species, B. motasi and B. crassa, probably resulted from cross-reactions and the presence of these two species is doubtful. Antibodies against B. ovis were found in animals from more than 90% of the localities. T. ovis was also common, but it was confined essentially to sheep. The examination of Giemsa stained blood smears revealed the presence of T. ovis and B. ovis in sheep, and Anaplasma ovis in a goat.
