Sagot :
Answer:
Klebsiella pneumoniae
Step-by-step explanation:
> A sputum culture from an alcoholic seen in the ER grows gray, mucoid, stringy colonies on sheep blood agar. The isolate grows readily on MacConkey agar and forms mucoid, dark pink colonies. The colonies yield:
ONPG: + indole: - glucose: +
oxidase: - citrate: + VP: +
- Klebsiella is the only distractor that is VP positive, and the other biochemical rxns are typical for Klebsiella pneumoniae.
