Prevalence and Risk factors of Trypanosomaevansi infections in Slaughtered Camels (Camelus dromedarius) in Tamboul Slaughterhouse, Sudan

Abstract

This study was conducted between November to December 2016 in order to determine the prevalence of camel trypanosomosis (Guffar, or Surra) which caused by haemoprotozan parasite Trypanosoma evansi (T. evansi) and also to determine the risk factor may associate with the disease in Tamboul Slaughterhouse, East of Gazira state from. Blood samples were collected randomly from 165 camels using heparinized, tubes. These samples were examined for the presence of T. evansi using Giemsa-stained smears and Haematocrit Centrifugation Technique (HCT) and the infection rates were 7 out of 165 (4.2%) and 8 out of 165 (4.8%) respectively. These results indicated that the (HCT) was more specificity compared with Giemsa-stained smears to diagnose camel trypanosomosis. Only one risk factor, body condition, was statistical significant (p-value < 0.25) associated with trypanosomosis infection in camel. However, the different in the prevalence rate of cameltrypanosomosis based on the sources of animals, breed, sex and age where the higher rate was reported in animal from Butana and West Sudan (5.1% for both), Butana breed and Kassala breed (5.1% for both), female and older animal, respectively
