Bovine Babesiosis in Elfasher Locality – North Darfur State

Abstract

This study was conducted in September 2017 to March 2018 in Elfasher Locality – North Darfur State to identify Babesia species and ticks infected cattle and to determine some hematological and biochemical parameters associated with these species. A total of 227 whole blood samples were collected from cattle randomly in Elfasher Locality for identification of Babesia parasites using Gemisa stain. Packed cell volume was determined in 100 samples by using microhematocrit technique. Biochemical parameters [Total protein, albumin, bilirubin, calcium, sodium and potassium] were determined in 100 serum samples. One hundred and fifty five tick samples were collected from 23 cattle for identification. The result revealed that 133 smear samples were positive to Babesia species with overall prevalence rate 58.5%. A significant decrease of packed all volume [p<0.01]. All biochemical parameters showed no statistical significant difference, but serum calcium showed significant difference [p<0.01]. There were 2 genera of ticks were identified and these were Ripicephalus and Hyalomma, included 7 species and these were Ripicephalus evensi eversi [37.5%], Hyalomma anatolicum [21.9%], H.impletatum [16.2%], H.dromedarii [12.9%], H. rufipes [1.2%], H. truncatumim [9.0%] and H.predixtatus [1.2%]. In conclusion, bovine babesiosis is the most important tick – borne disease of cattle in Elfasher locality leading to death of the animals due to anemia.
