Erusipelothrix bergeys
regular, non-sporing gram + rods, vol 2 then 3
Domain, phylum
Bacteria, Firmicutes, eErysipelotrichia, Eryriselpelotichales, Eryrisipeloaceae
What are 2 of the 8 genera?
Bulleidia and Holdemania
What are the 3 species and what do they do?
E. rhusiopathiae - vet pathogen, sometimes human. E. tonsillarum - healthy pig tonsils, E. inopinata - plants
General properties of E. rhusiopathiae
gram +, straight/slightly curved rods, can form long filaments, non-motile, facultative anerobes, catalase and oxidase neg
Cell wall
R-3 = L-lysine. Tetrapeptide crosslinks 2 to 4
Natural habitat
domestic pigs. infection is mostly occupational exposure
E. rhusiopathiae capsule
polysaccharide capsule. evades phagocytosis but also helps by keeping it alive if phagocytized. Nine antioxidants help keep it alive intracellularly
E. rhusipathiae RspA and RspB
Rhusiopathiae surface proteins. adhere to biotic and abiotic surfaces to start biofilms
E. rhusiopathiae Neuramidase
Plays major role in bacterial attachment and invasion of cells
E. rhusiopathiae disease
erysipeloid lesion, general skin problems, septicemic form (causes endocaritis)
Grow Erysipelothrix
grow on blood and chocolate agar. Some require 5% CO2 incubation
Erysipelothrix hemolysis
gamma or alpha. NEVER BETA
Erysipelothrix tests
H2S production, Vancomycin resistant,
Erysipelothrix primers
RspA, RspB, SpaA, SpaB, SpaC
