Prevalence of the Theileriosis Infection in Animals Dairy Cattle Farms in Khartoum Bahri, Khartoum State, Sudan

Abstract

This study was conducted from February to March 2020 in Khartoum Bahri, Khartoum, State to determine the prevalence of bovine theileriosis and its associated risk factors of the disease. A total of 150 blood samples were collected randomly from dairy cattle farm in Bahri (kuku, Alkadru, Soba, Alselat) for detection of theileria blood parasite using direct Geimsa stain techniqueand for hematological parameters using complete blood counts machine. Questionnaire was filled by farms owners to identify possible risk factors associated with theileria infection. These including; locality, age, sex, body condition, tick’s infestation and use of acaricides. Results showed that the overall prevalence of theileria in Khartoum Bahri was (28.6%). The high prevalence rate was recorded in Alselat (34.4%) compared with other Alkadaru (25%), Soba (26.1%) and Kuku (32.3%). The high prevalence was record in age >4years (44%), <2(24%) and 2-4years (27.2%). The high prevalence in male (30.5%) followed by female (28%) and high prevalence recorded in animals with poor body condition (30.5%) compared with good body condition one (27.4%). The univariate Chi square analysis showed that there was no relationship between ages, sex, body condition, ticks infestation and use of acaricides but there was significant (P<0.05) association of tick’s infestation and body condition. Independent t, test of hematological parameters the result showed that there was significant different of RBCs and HGB (P-value=0.02 and 0.01) respectively. The ccurrent study concluded that dairy cattle were highly infected with theileria due to poor management and ticks control of the diseases. Also the disease affected some of hematological parameters in blood component of infected animals.
