Cutaneous Form

<em>Erysipelothrix</em> <em>rhusiopathiae</em> is a Gram-positive bacillus that is infrequently responsible for infections in humans. Three forms have been classified: a localized cutaneous form (erysipeloid) caused by traumatic penetration of <em>E.</em> <em>rhusiopathiae</em>, a generalized cutaneous form and a septicemic form. The latter type of disease has been previously associated with a high incidence of endocarditis. Here we report a case of <em>E. rhusiopathiae</em> bacteremia in a 74- year-old man, probably started from an erysipeloid form, in which endocarditis did not develop. This case presents some particular and uncommon features: i) no correlation with animal source; ii) correlation between bacteremia and erysipeloid lesion; iii) absence of endocarditis. MALDI-TOF mass spectrometry allowed to obtain a rapid identification (within 4 hours from bottle positivity) of <em>E. rhusiopathiae</em>. Together with direct antimicrobial susceptibility testing, this approach could improve the rate of appropriate therapy for bloodstream infections due to this fastidious pathogen.
