Abstract

Erνsipelothrix rhusiopathiae is a facultatively anaerobic gram-positive rod, which is primarily a pathogen of swine and other animals, but it can also cause human infection, the most common being erysipeloid and rarely implicated in systemic infections. Erysipelothrix rhusiopathiae was isolated from a blood specimen obtained from a 45-year-old man, who had gangrene of the leg right. The isolate showed typical cultural and biochemical characteristics such as facultative growth, formation of small greenish colonies on blood agar, positive hydrogen sulfied in TSI agar, negative catalase, and absence of motility. The isolate was susceptible to penicillin, cephalosporins, and teicoplanin but resistant to vancomycin and gentamicin in a disk diffusion test.
