Abstract
The study was aimed to investigate the pathological changes of condemned lungs of dromedary camels in the Sudan abattoirs using conventional H & E and Zeihl Neelson (ZN) staining procedures. Proliferative granulomatous reaction was demonstrated in one H & E stained lung section which was characterized by focal fibrosis and infiltration of mononuclear cells resembled to tuberculous lesions. While ZN stained sections demonstrated acid fast rod in one pulmonary associated lymph node. These lesions were evidenced presence of tuberculous mycobacteria in camel tissues and recommended further deep investigation of tuberculosis among camels in the Sudan.

Summary
Tuberculosis (TB) is a chronic contagious tuberculous disease having a zoonotic impact and economic potential worldwide [1] [2]. TB remains one of the most prevalent and devastating diseases of man and animals caused by Mycobacterium tuberculosis complex. While birds and wild animals participate in epidemiological cycle of the disease as vectors [2]. The diagnosis of TB in camel depends mainly on the pathology and detection of pulmonary, lymphatic, mastitic and milliary tubercles as well serology and tuberculin skin test as screening tests whereas microscopy, culturing and molecular approaches have a confirmative diagnostic impact [5] [6] [7] [8] [9]. The causative agents of camel tuberculosis were identified as My-
