Abstract
A total of 3 camels from different herds were submitted separately for postmortem examination including histopathological investigation. These animals were off feed, emaciated and showed chronic and intermittent diarrhoea for 1-3 weeks. Gross pathological examination of these cases revealed thickening of the intestinal wall up to 3 or 4 times normal thickness, with corrugation of the serosa and mucosa. Mesenteric lymph nodes were moderately large and oedematous. Histopathological lesions were diffuse granulomas characterised by extensive macrophages and epitheloid cells infiltration into the mucosa and submucosa of small intestine, and colon, with numerous acid-fast organisms. Multinucleated giant cells, as well as lymphocytes and few numbers of eosinophils were also observed. The ileocaecal lymph node, as well as other mesenteric lymph nodes showed sinus histiocytosis, infiltration of macrophages and epitheloid cells containing acid-fast bacilli, and occasional multinucleated giant cells.
