We report a case of bacterial endocarditis due to Erysipelothrix rhusiopathiae in a homeless man with no animal exposure. His course was complicated by an allergic reaction to ampicillin, urinary bladder infection, respiratory failure, and acute kidney injury. He recovered completely after aortic valve replacement and a 6-week course of intravenous ceftriaxone.

Infection with Erysipelothrix rhusiopathiae has a significant economic impact on pig production systems worldwide. Both inactivated and attenuated vaccines are available to prevent development of clinical signs of swine erysipelas. The ability of a live attenuated E. rhusiopathiae strain to become persistently established in pigs after intranasal exposure and its potential to cause clinical sig...

Avian cellulitis is a serious problem for the commercial broiler industry. Although various agents were isolated from cellulitis lesions, the ability of Erysipelothrix rhusiopathiae in reproduction of cellulitis is not known. Therefore, the objective of this study was to evaluate the ability of these bacteria for induction of avian cellulitis. The study involved two experimental groups, each co...

Langford and Hansen (1954) have suggested that the genus Erysipelothrix possesses a single species Erysipelothrix insidiosa and that subdivision into further species is not justified; following their terminology E. insidiosa and E. rhusiopathiae in this account are considered synonymous. Erysipelothrix rhusiopathiae is recognized as the pathogen causing the skin lesions of human erysipeloid. Th...

INTRODUCTION The present report describes a case of sepsis due to Erysipelothrix rhusiopathiae in a patient with B-cell chronic lymphocytic leukemia with no animal exposure, associated with concomitant bronchopneumonia due to Pseudomonas aeruginosa and Escherichia coli. CASE PRESENTATION A 54-year-old Caucasian man presented to an emergency room with a three-day history of chest pain, fever, ...

Erysipelothrix rhusiopathiae (E. rhusiopathiae) is the causative agent of swine erysipelas. This microbe has caused great economic losses in China and in other countries. In this study, high-throughput cDNA microarray assays were employed to evaluate the host responses of porcine heart to E. rhusiopathiae and to gain additional insights into its pathogenesis. A total of 394 DE transcripts were ...
