1982 as a group of facultative anaerobic, asporogenous, and Gram-stain positive rods. According to Yassin et al. (2011) , this genus consists of four species, namely, Arcanobacterium haemolyticum, Arcanobacterium hippocoleae, Arcanobacterium phocae, and Arcanobacterium pluranimalium. Arcanobacterium haemolyticum 1.3 x 1.5-8µm. Cells often stain irregularly.

Key words: Arcanobacterium haemolyticum, intrathoracic mass lesion, diabetes mellitus, compromised host Introduction Arcanobacterium haemolyticum (formerly Corynebacterium haemolyticum ) was first described in pharyngitis and skin lesions by MacLean in 1946 (1) , (2) , and it is a β-hemolytic, gram-positive, rod-shaped, and catalase-negative bacillus (1) , (2) .
Arcanobacterium haemolyticum on gram stain of growth from throat culture. Arcanobacterium haemolyticum (formerly Corynebacterium haemolyticum [3]) is an aerobic, catalase-negative, gram-posi-tive rodwhichhasbeenisolatedfrompatientswithpharyngitis, wound infections, septicemia, endocarditis, and osteomyelitis (9). Biochemically and by Gram stain, it is not difficult to Rhodococcus equi and Arcanobacterium haemolyticum, formerly classified in the genus Corynebacterium, are members of the loosely defined taxon "coryneform" bacteria.
Key words: Arcanobacterium haemolyticum, intrathoracic mass lesion, diabetes blood agar; (b) Gram stain of Arcanobacterium haemolyticum in blood culture.
The following Gram stain was performed on a blood culture taken from a 40-50 year old paraplegic with sacral sores. Curved Gram-positive bacilli seen with “Chinese letters and V-forms typical of coryneform bacteria. Arcanobacterium haemolyticum is a catalase negative gram-positive rod, showing narrow zones of beta-haemolysis when cultured on human or rabbit blood agar6, 10. A.haemolyticum was identified by typical colony morphology, Gram stain, catalase reaction (negative), and carbohydrate fermentation tests (glucose, lactose, sucrose, mannitol, and maltose) and reverse CAMP test. Arcanobacterium haemolyticum Gram Stain.

Arcanobacterium haemolyticum, formerly known as Corynebacterium hæmolyticum, is a species of bacteria classified as a gram-positive bacillus. It is catalase-negative, aerobic, beta-hemolytic, and not motile. It has been known to cause head and neck infections, pharyngitis, and sinusitis (Arcanobacterium haemolyticum infections
Arcanobacterium haemolyticum is a gram-positive, facultative anaerobic, branching bacillus. The first cases ascribed to this pathogen were described in 1946 and caused ulcerative skin lesions among American soldiers in the Pacific Islands.
