Name 4 features shared by Klebsiella, Serratia, and Enterobacter
(1) Ferment lactose
(2) Cause Pneumonia/UTI
(3) Nosocomial infections
(4) ⇒ Often Multi-Drug resistant
(Serratia is a slow fermenter of lactose, so it may show up negative on MacConkey)
Characterize (3) : Enterobacter
(1) Gram (-) rod
(2) Lactose fermenter
(3) Motile
Characterize (4) : Serratia
(1) Gram (-) rod
(2) Lactose fermenter
(3) Motile
(4) Produces red pigment
Characterize (4) : Klebsiella
(1) Gram (-) rod
(2) (+) Urease
(3) Lactose fermenter
(4) Capsule
(Capsule is responsible for the “current jelly” sputum)
Name 3 major associations with Klebsiella
The 3 As:
(1) Alcoholics
(2) Abcesses
(2) Aspirations
Name 2 distinctions between Klebsiella from Serratia and Enterobacter
Klebsiella is:

(2) Immotile

“Food poisoning: self-limiting diarrhea, acute septicaemia in immunosuppressed with high fever, hypotension and multiple erythematous skin lesions which turn hemorrhagic, necrotic and ulcerating (elderly males with alcoholic liver damage particularly at risk)”
