Enterics Flashcards
All enterics are
GN, rod or coccobacilli, no spores ubiquitous facultative anaerobes BAP: large, moist, and grey Ferment Glucose Reduce nitrates to nitrites
Most enterics
Oxidase neg (except plesiomonas) Motile (except Kleb, Shigella, and Yersinia and 1 ecoli)
Most commonly seen in lab
E. coli, Kleb pneumoniae, Proteus mirablis
Fecal coliforms
Ecoli
Non fecal coliforms
Citrobacter, Kleb, and Enterobacter
O antigen
Somatic antigen;Heat stable Ag on cell wall
H antigen
Flagellar antigen; Heat labile Ag on flagella
K antigen
Capsular antigen; Heat labile Ag made of polysaccharide and in encapsulated spp only
- K1 Ag of E coli
- Vi Ag of S. typhi
