Abstract
The aim of this study was to determine the occurrence of tuberculosis in cattle slaughtered at Nyala abattoirs, South Darfur State, Sudan during the period April 2006 – May 2008. In total 2794 cattle were examined for tuberculous lesions. Tuberculous lesions (n = 163) were found in 40 (1.4%) animals, among which seven had generalized tuberculosis and 33 localized tuberculosis, mainly in the lungs, thoracic lymph nodes, and/or in the liver, spleen, kidneys and mesenteric lymph nodes. Tissue samples were collected either in 10% formal saline for routine histopathology or in ice packs for direct microscopy and culturing. Direct microscopy showed that 124 (76.1%) tuberculous lesions harbored acid fast bacilli, whereas 17 (10.4%) isolates of Mycobacterium spp. were recovered in pure Lowenstein-Jensen medium cultures and identified as M. bovis (n = 11) and M. farcinogenes (n = 6). Granulomatous inflammation was evident in all sections of tuberculous lesions. Further studies are needed to identify mycobacteria species causing tuberculosis in other animal species.
