Abstract

In Algeria, the absence of means of screening for tuberculosis goats on the living animal, the post-mortem inspection of goats’ carcasses at slaughter is the only way possible, but this is not always the case because of the illegal felling of this species. This study was conducted in two slaughterhouses in Algeria, over a period of two months in order to determine the proportion of goats’ tuberculosis and highlight the agents. Out of 995 carcasses inspected, 60 showed suspicious lesions of TB, a proportion of 6.03%.  Microscopic examination showed a positivity of 13.33%. As for culture, a percentage of 10.01% of positive cases was noted. The molecular diagnostic tools have revealed no strain of Mycobacteium tuberculosis complex. While the sequencing of gene16SrRNA showed two strains belonging to Corynebacterium xerosis, a strain of non tuberculous mycobacteria, a strain of Corynebacterium sp. whose species has not been determined, a strain of Corynebacterium pseudotuberculosis and a strain of Desulfosporosinus sp.  Therefore, we confirmed the absence of goats’ tuberculosis  in both slaughterhouses.
