title: Instability of ovine babesiosis in an endemic area in Turkey.
abstract: This study was designed to determine the endemic status of Babesia ovis in sheep in Turkey. A total of 2000 sheep, from different age groups (i.e. 0-3, 4-6, 6-9, 10-12, and >12 months), were selected randomly from 132 sheep flocks. The presence of specific antibodies against B. ovis was diagnosed by indirect fluorescent antibody test (IFAT). A total of 843 (42.15%) serum samples were determined to be positive. The seropositivity rates in the age groups stated above were 31.90, 31.64, 47.69, 40.22, and 52.99%, respectively. The endemic status of the disease was determined by calculating the inoculation rate (h) of each group. The h value for each group was determined to be lower than 0.005, which revealed that the endemic status of B. ovis was instable. This report may indicate the necessity of vaccination.
