seroprevalence of theileria ovis in goats from m’sila region, central algeria

Background: in algeria, data on the epidemiology of theileriosis in small ruminants are limited. objectives: the current study investigates the seroprevalence of theileria spp. in goats from the m’sila region, central algeria. methods: blood samples of 128 goats from 19 farms were collected from the locality of maâdid. the indirect fluorescence antibody test (ifat) was performed to test the goats’ sera for antibodies against theileria ovis and theileria lestoquardi. results: out of 128 tested samples, 21 sera (16.40%) were positive for t. ovis antibodies. all samples were seronegative for t. lestoquardi. the seroprevalence of t. ovis varied from 10% to 30% on farms. the seropositivity rates did not differ significantly with age, sex, or breeding system of goats. tick-infested goats were significantly more seropositive than no-infested goats. conclusion: the present study reports essential data on the epidemiology of caprine theileriosis from central algeria.
