Klebsiella pneumoniae is identified through a combination of biochemical tests: Gram-negative pink rods with thick clear capsule, oxidase negative, lactose fermenter (pink colonies), indole negative, citrate positive (green to blue), urease positive (light orange to pink), non-motile, and VP test positive (colorless to red); the combination of mucoid colonies, capsule, and lactose fermentation confirms Klebsiella pneumoniae.

Gram negative. Capsule stain. Thick clear capsule visible. Catally bubbles appear. Positive. Oxidase. No purple color. Negative. Lactose fermentation.
Pink colonies appear. Positive. Indole.
No red ring. Negative. Citrate. Green to blue. Positive. URes. Light orange to pink. Positive. Motility. No spread.
Non-motile.
VP test. Colorless to red. Positive.
