Abstract:
Contagious caprine pleuropneumonia is a bacterial infection of goats. It is caused by a bacterium belonging to the Mycoplasmataceae family and the Mycoplasma genus. Causative agent of the disease is Mycplasma capricolum subspecies capripneumoniae (Mccp). This disease causes significant economic losses in Asia and Africa. Because of the very high morbidity and mortality and its socio-economic impact, contagious caprine pleuropneumonia is on the OIE list of notifiable diseases. This disease affects mainly goats and occasionally sheep, but also wild ruminants. Contagious caprine pleuropneumonia is characterized by cough, dyspnoea and very high mortality and morbidity, fibrinous pleuropneumonia, unilateral lung hepatization and accumulation of pleural fluid in the thoracic cavity. Animals are infected by inhalation of dropes expelled by sick animals. Direct contact is essential for infection to occur. The porosity of borders shared with other countries and the lack of financial resources allocated to the national animal disease surveillance system make it difficult to control cross-border livestock movements. This exposes the national herd to various infectious diseases, including contagious caprine pleuropneumonia. Cross-border movements linked to the international trade in animals, to transhumance, as well as to insecurity due to existing hotbeds of tension in African countries, lead to massive movements of herders and animals in search of pastures and water. All of this constitutes risk factors for the introduction and spread of viral and bacterial infections in the countries. The objective of this manuscript is to summarize the epidemiology and risk factors of contagious caprine pleuropneumonia in Chad based on bibliographical data.
