Arcanobacterium haemolyticum was usually isolated from respiratory infection. Occasionally, the cases were reported to cause pharyngotonsillitis, cellutitis, and abscess. A. haemolyticum is V form gram-positive bacilli (coryneform bacilli), which isoften considered to be non-pathogenic normal flora or contaminants in respiratory, skin and wound infection. In order to discriminate from normal flora, incubation for at least 48 hours is recommended. We describe a case that A. haemolyticum was isolated from cellulitis with group G ${\beta}$-hemolytic Streptococcus, Klebsiella pneumoniae ssp. pneumoniae, and Prevotella disiens.

A 4-year-old Holstein cow with progressive atrophy and ataxia was submitted for diagnosis. The postmortem examination revealed multifocal yellowish nodules in the pulmonary parenchyma and vegetative masses in the mitral and tricuspid valve of the heart. Both kidneys were severely enlarged, with multiple yellow nodules on the parenchyma. Histopathologically, pulmonary abscesses, vegetative endocarditis, suppurative glomerulonephritis, and fibrino-purulent arthritis were observed. The tiny β-hemolytic bacterial colonies were isolated from the lesions and identified as Arcanobacterium haemolyticum by the VITEK 2 system (bioMérieux, USA). This is the first documented report of an A. haemolyticum infection in a Holstein cow in Korea.
