Prevalence and Risk Factors associated with Bovine Theileriosis and Ticks Infestation in Northern State-Sudan

Abstract

This study was conducted for determination of bovine theileriosis and investigation of associated potential Risk Factors and cattle tick infestation in Northern State, Sudan. A total of 329 blood samples were collected randomly from cattle from January 2018 to January 2019 and examined for blood parasite using direct smear Geimsa stain method. Questionnaire was included; locality, breed, sex, age and season. Also 1252 tick samples were collected from 313 cattle in 70% ethanol for identification. Blood smears were reveled 11.6% prevalence rate of the disease. The following risk factors showed association with cattle theileriosis in the univariate analysis under significant level of P-value ≤ 0.25: sex (P-value= 0.432), age (P-value =0.001), breed (P-value= 0.000) , previous history of disease of the animals (p-value=0.005), present of ticks in animals (p-value=0.000) , there was two genera of ticks were identified which were Hyaloma and Rhibocephalus. Six species of these two genera were H.rufipus, H.trancatum H.dromadarii, H.impltatum, H.anatolicum and R.evansi. In conclusion, the disease is prevalent in Northern state.
