Frequency of Theileriosis in Cows in Tehsil Paharpur, Dera Ismail Khan
Keywords:Epidemiology, Hematology, Pyrexia, Theileria, Ticks
Bovine Theileria is an intracellular parasite that infects its hosts with both severe and mild illnesses, clinically characterized by pyrexia, lymphadenitis, conjunctivitis, diarrhea and ocular discharges. It is a highly economical infection therefore, this research was conducted for investigation of occurrence of theileriosis in cows in Tehsil Paharpur of Dera Ismail Khan through a hematological investigation of 384 cows during the year 2021-22. The overall Theileria prevalence in cattle was 12.23%, most of the affected population comprised females revealing 12.35% (44/356) positive cases with Theileria, while a 10.71% prevalence rate was recorded in males (3/28). Season-wise prevalence was highest (p<0.05) in the summer season (19.79%), followed by rainy (14.58%), and spring (8.33%) and the lowest incidence was recorded in winters (6.25%). Age-wise prevalence of theileriosis indicated that animals of age less than a year (16.09%) were more prone to the infection (p<0.05) than the age group of 1-3 years (11.79%) and above (9.41%), respectively. It was thus concluded that in Tehsil Paharpur, theileriosis was determined to be quite widespread in cattle. There is a need for additional research using molecular techniques to identify the infection's carriers, and preventative measures must be implemented to eradicate the infection.
