Abstract:
In Mali, poultry farming is the main source of table eggs and broiler chickens. However, among the constraints to its development are those of a health nature in general and salmonellosis in particular. The objective of this study conducted in 2014-2015 was to assess the bacteriological prevalence of salmonellosis caused by Salmonella gallinarum in exotic and local hens in the peri-urban areas of Bamako, Ségou and Sikasso. 526 samples (515 cloacal swabs and 11 organ samples) from 182 chicken farms (exotic and local) collected and tested in culture. An overall bacteriological prevalence rate of 10.2% obtained with 9.7% in Bamako against 15.1% in Ségou and 8.0% in Sikasso. These rates varied according to the nature of the samples (9.5%, 14.2% and 6. 2% for cloacal swabs against 25%, 100% and 50% for organ samples respectively in Bamako, Ségou and Sikasso) and the type of poultry (9.2% in exotic hens and 27.5% in local chickens). Statistical analysis revealed no significant variation (p= 0.128>0.05 in Ségou, p=0.335>0.05 in Sikasso) in prevalence at the Ségou and Sikasso sites. On the other hand, it revealed a significant variation according to the types of samples and poultry (p=0.003<0.05). This study confirmed the persistence of avian salmonellosis in poultry farms located in peri-urban areas of Bamako, Ségou and Sikasso. 5% in local hens). Statistical analysis revealed no significant variation (p= 0.128>0.05 in Ségou, p=0.335>0.05 in Sikasso) in prevalence at the Ségou and Sikasso sites. On the other hand, it revealed a significant variation according to the types of samples and poultry (p=0.003<0.05).
