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
|
