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 (Pvalue=
0.000). there was two genera of ticks were identified which were Hyaloma and
