Enterobacteriaceae

-motile with the exception of Yersenia, Shigella, and Klebsiella
-ferment glucose (referred to as "fermenters")
-oxidase negative
-gram negative
*key terms* {obligate aerobes, aerotolerant anaerobes, obligate anaerobes,
facultative anaerobes, and capnophilic microaerophilic} *key terms*
-enterics (found mostly in the intestines)
-reduce nitrate to nitrite
-MAC and EMB plates
-GI specimens (stools) call for HE, XLD and GN broth
-large, shiny, moist, gray/grayish white. may or may not be hemolytic, translucent and
slightly convex, some mucoid
-utilize: carbohydrates, citrate, urease, indole.
-produce hydrogen sulfide (H2S), metabolize tryptophan (amino acid)
-IMVIC:
