The prevalence of Theileria spp. infection and ticks was studied in sheep in eight districts of Karnataka (South India). Blood samples and ticks were collected from 110 sheep during a period from March 2015 to February 2016. Microscopic examination of Giemsa stained blood smears revealed Theileria spp. organisms in 53.63% of sheep. The parasitemia ranged between 1.0 to 1.2 and 0.1 to 0.3% in clinical and carrier sheep respectively. Out of 692 ticks collected, Haemaphysalis kutchensis (51.44%) was predominant species followed by Rhipicephalus haemaphysaloides (30.20%), H. intermedia (7.36%), H. bispinosa (6.06%) and R. sanguineus (4.91%).
