'''''Erysipelothrix''''' is a genus of bacteria containing four described species: ''Erysipelothrix rhusiopathiae'', ''Erysipelothrix tonsillarum'', ''Erysipelothrix inopinata'' and ''Erysipelothrix larvae''.<ref name=LPSN/><ref>{{cite journal |last1=Takahashi |first1=T. |last2=Fujisawa |first2=T. |last3=Benno |first3=Y. |last4=Tamura |first4=Y. |last5=Sawada |first5=T. |last6=Suzuki |first6=S. |last7=Muramatsu |first7=M. |last8=Mitsuoka |first8=T. |title=''Erysipelothrix tonsillarum'' sp. nov.

The best-known species within the genus is ''Erysipelothrix rhusiopathiae'', which is the cause of erysipelas of domestic pigs, poultry and other animal species. In humans, ''E. rhusiopathiae'' infections are termed erysipeloid. ''Erysipelothrix tonsillarum'' has been described as a pathogen for dogs and has been isolated from the tonsils of healthy pigs and cattle.<ref>{{cite journal |last1=Takahashi |first1=T |last2=Tamura |first2=Y |last3=Yoshimura |first3=H |last4=Nagamine |first4=N |last5=Kijima |first5=M |last6=Nakamura |first6=M |last7=Devriese |first7=LA |title=''Erysipelothrix tonsillarum'' isolated from dogs with endocarditis in Belgium. |journal=Research in Veterinary Science |date=March 1993 |volume=54 |issue=2 |pages=264–5 |pmid=8460272|doi=10.1016/0034-5288(93)90071-M }}</ref> Disease caused by ''E. inopinata'' or ''E. larvae'' has not been described.
Bacteria of genus ''Erysipelothrix'' are straight or slightly curved, slender, nonmotile rods that may exist singly, in V-shaped pairs, or in short chains. Some strains have a tendency to form long filaments. The bacteria are Gram-positive but can be mistaken for Gram-negative bacteria during analysis because they lose their staining easily. They are aerobic to facultatively anaerobic but not acid-fast.<ref>{{Citation |last1=Stackebrandt |first1=Erko |title=The Genus Erysipelothrix |date=2006 |work=The Prokaryotes |volume=4 |pages=492–510 |editor-last=Dworkin |editor-first=Martin |place=New York, NY |publisher=Springer US |language=en |doi=10.1007/0-387-30744-3_13 |isbn=978-0-387-30744-2 |last2=Reboli |first2=Annette C. |last3=Farrar |first3=W.
