Enquete sero-epidemiologique sur la tuberculose, la brucellose, la toxoplasmose, la rhinotracheite infectiuse et les salmonelles abortives chez les animaux bresiliens introduits au Bukinafaso

Abstract

A survey on tuberculosis, brucellosis, bovine infectious rhinotracheitis, toxoplasmosis and abortive salmonellosis has been carried out in Brazilian breeds (Gyr and Gyrolando) introduced in Burkina Faso. The study has concerned two livestock system : The modern system with two herds located in Koubri and Loumbila (rearing station of the Centre National d’Elevage et d’Amélioration Génétique (CNEAG). The traditional system with the agro-pastoral zone’s herd of Kikideni, eastern Burkina Faso. Animals (n = 273) have been tested for the presence of tuberculosis, brucellosis, bovine infectious rhinotrachetis (IBR), toxoplasmosis and salmonellosis.
Results have shown a prevalence of 16.42%, 7.32%, 3%, 77.73%, and 76.04%of for brucellosis, tuberculosis, toxoplasmosis, bovine infectious rhinotracheitis and abortive salmonellosis respectively. Results have also revealed a high seroprevalence rate for abortive diseases which are not routinely diagnosed in Burkina Faso such as toxoplasmosis and salmonellosis and the presence of multiple abortive infections within the same animal. This survey suggested systematic control of abortive diseases which could improve animal productivity.
