Abstract
Tuberculosis (TB) is a widespread and endemic disease of ruminants in Algeria posing a significant threat to public health. A retrospective abattoir study was conducted in Bejaia province (Algeria) from 2009 to 2018 to estimate the prevalence of tuberculosis in cattle, sheep, and goats using detailed meat inspection procedure. The overall prevalence of tuberculosis was 2.06% (4092/199 077) in cattle, 0.007% (11/168 796) in sheep, and 0.008% (11/164 986) in goats. The annual prevalence rate of the disease showed intermittent increase in levels over the ten years period of the study. However, monthly fluctuations of tuberculous lesions in slaughtered cattle were recorded throughout the study period with detection rates ranging from 1.77% and 2.36%. In addition, the variation in seasonal prevalence in cattle and goats is not significant (P > 0.05). Our analysis has revealed the magnitude of TB in the study area and warrants further systematic investigation on the transmission of the disease in Algeria.
