Erysipelothrix rhusiopathiae
MICROBIOLOGY
- Aerobe or facultative anaerobe, thin, pleomorphic Gram-positive rod.
- Zoonotic infection more commonly infects turkeys, pigs and other animals than humans.
- E. rhusiopathiae is the only genus within the species that infects humans.
- Culture isolation is difficult.
- A slow grower in enriched blood media with 5-10% CO2.
- Intrinsically resistant to vancomycin, which commonly might be used empirically unless the organism is appropriately identified and distinguished from diphtheroids (Corynebacterium spp.) and Lactobacillus.
- The lab can confuse with diphtheroids and coryneforms, but E. rhusiopathiae is distinguished by H2S production.
- Also usually resistant to aminoglycosides and sulfonamides.
