Abstract:
The increase in prevalence of tick borne parasites and their economic impact on livestock production have given way for better diagnostic tools and treatment. This study was conducted to study the prevalence and its diagnosis of haemoprotozoan parasites from sheep ticks. The salivarygl and of different tick spp. was subjected for PCR, in which about 13 percent of Haemaphysalis species of ticks amplified for Theileria wenshui by nested PCR and Hyalomma spp. amplified for T. ovis in organised farms. Whereas in unorganised farms 17 percent of Haemaphysalis spp. of ticks viz., H. kutchensis showed amplification at 388bp for T. luwenshuni by nested PCR and Hyalommaantoli cumanatolicum showed amplification of 237bp for T. ovis. Other species of ticks in the study viz., Rhipicephalus and Hyalomma marginatum sasi did not show amplification for haemoprotozoan parasites. The highest number of H. kutchensis showing amplification for T. luwenshuni and H. a. anatolicum showing amplification for T. ovis was considered as potential vector in disease transmission of T. luwenshuni and T. ovis in sheep in Karnataka.
