PREVALENCE AND RISK FACTORS ASSOCIATED WITH CONTAGIOUS BOVINE PLEUROPNEUMONIA IN KHARTOUM STATE, SUDAN

Abstract

Contagious Bovine Pleuropneumonia (CBPP) is one of the serious threats to the livestock in Khartoum State. This study was carried out to asses the prevalence of Contagious Bovine Pleuropneumonia (CBPP) in Khartoum State by serological technique and to identify risk factors associated with the disease. A total of 192 serum samples were collected randomly from animals in different areas of the state and tested for antibodies against Mycoplasma mycoides subsp. Mycoides (small colony type) using c- ELISA. xii Thirty three samples were seropositive for CBPP with c-ELISA test. The prevalence of CBPP in Khartoum State based on c-ELISA was estimated as 17.19%. The results of univariate analysis revealed that seropositivity to CBPP was significantly higher in animals vaccinated (P- value= 0.098), in animals more than 12 months in age (P- value= 0.196) , when the herd size was less than 20 animals (P- value= 0.147) and in animals that did not share with other herds in grazing land (Pvalue= 0.127). and, when there was heavy insect population (Pvalue= 0.000). In the multivariate analysis, only insect population was identified as the major risk factor (P- value= 0.004) associated with CBPP.
