A Study of Bovine Babesiosis in El-fasher - North North Darfur State - Sudan

Abstract

This study was conducted from September 2017 to March 2018 in Elfasher locality –North Darfur State, to identify Babesia species and tick infected cattle and to measure some hematological and biochemical parameters associated with bovine babesiosis. A total of 227 whole blood were collected from Elfasher locality [Elfasher veterinary hospital, Elfasher slaughter house, and cattle farms in Elfasher ]. For identification of Babesia using thin smear Giemsa stain. Packed cell volume was measured in 100 blood samples using hematocrit technique. Biochemical parameters were determined in 100 serum samples were total protein, albumin, bilirubin, calcium, sodium and potassium. One hundred and fifty five ticks were collected from 23 animals for identification using Estrada standerd. The result revealed that 133 smear samples were positive to Babesia spp. [58.5%]. Packed cell volume was statistically significant decreased when compared with non-infected [p<0.01] animals. All biochemical parameters showed no statistical significant decrease when compared with non infected animals [p<0.01 ].There were 2 genera of tick were identified and these were Hyalomma and Rhipicephalus. These genera included 7 species and these were Rhipicephalus eversi [37% ], Hyalomma anatolicum [21.9%], H. impeltatum [ 16.2%], H. dromedarii[ 12.9%], H. rufipes [1.2%] and H. truncatum [ 9.0%],H. predixtatus [1.2%]. In conclution, bovine babesiosis the most important tick –borne disease in Elfasher locality leading to death of the animal due to anemia.
