An assessment of caprine tuberculosis prevalence in Lubumbashi slaughterhouse, Democratic Republic of Congo

Caprine tuberculosis is a major health problem for goats and a major zoonosis of veterinary public health interest. In order to prepare a response to and control of caprine tuberculosis, to evaluate the potential risks to public health, and to assess the prevalence of the disease in Katanga province, Democratic Republic of Congo, 656 goats that were slaughtered at the Kabasele abattoir of Mzee Laurent-Desire Kabila Market in Lubumbashi were subjected to rigorous veterinary inspection during June to August 2012. All goat specimens came from the Kasumbalesa, Kasenga, and Kipushi areas of Katanga province. Consequently, suspected organs presenting signs of tuberculosis were collected and examined using Ziehl-Neelsen stains for diagnosis. Through this investigative inspection in the province, we found an overall prevalence of caprine tuberculosis of 1.68%. Although females showed higher prevalence of caprine tuberculosis (1.07%) compared to males (0.61%), and adults showed higher prevalence (1.22%) than juveniles (0.45%), these comparisons were not statically significant. However, lung and intestine infection by tuberculosis showed significantly higher prevalence of positive cases (1.21 and 0.46%, respectively) (p < 0.05). Goats from Kasumbalesa had the highest prevalence of caprine tuberculosis (1.22%) compared to goats from Kipushi (0.31%) and Kasenga (0.18%). These findings show the risk of caprine tuberculosis in the province for the first time, and we therefore recommend the implementation of strict animal biosecurity and tuberculosis controlling protocols.
