A new case of pulmonary tuberculosis with Mycobacterium bovis in a dromedary (Camelus dromedarius) in Mauritania

Abstract

A case of pulmonary tuberculosis is described in a dromedary from Nouakchott (Mauritania). Gross lesions affected pulmonary parenchyma, diaphragmatic pleura, pericardium and regional lymph nodes: caseo-calcified nodules, miliary tubercles and haemorrhagic “pendeloques”. Microscopically lesions were characterised by granulomatous tissue, epithelioid cells, necrotic material in the centre. No Langhans giant cells were seen. Mycobacterium bovis was isolated from these samples.
