This study was conducted in Nyala, South Darfur State, Sudan during August-September 2015 to study the seroprevalence of ovine and caprine theileriosis and to identify the tick infesting sheep and goats. For this purpose, total of 150 samples (ticks, blood smear and sera) were collected from sheep (n=61) and goats (n=89) of different age groups, breed and both sex. Three age groups were included: less than one-year-old, one-two years-old and more than two-year-old. Two diagnostic techniques were used, blood smears, and indirect fluorescent antibody test (IFAT). Out of 150 samples, 9 (6%) were positive for Theileria spp. piroplasms in blood smears, and 81 (54%) were positive for Theileria lestoquardi antibodies. Out of 61 sheep, 3 (4.9%) were positive for Theileria spp. piroplasms, and 25 (41%) were positive for T. lestoquardi antibodies. Out of 89 goats, 6 (6.7%) were positive for Theileria spp. piroplasms, and 56 (62.9%) were positive for T. lestoquardi antibodies. The highest prevalence of T. lestoquardi was recorded among sheep and goats more than two-year-old. Two genera and 4 species of ticks were infested sheep and goats. These included Rhipicephalus evertsi evertsi, R. s. sanguineus, Amblyomma variegatum and A. lepidum. The study concluded that the malignant ovine theileriosis is endemic in Nyala town.
