Is Enterobacter aerogenes positive for citrate?

Klebsiella aerogenes, previously known as Enterobacter aerogenes, is a Gram-negative, oxidase negative, catalase positive, citrate positive, indole negative, rod-shaped bacterium. The bacterium is approximately 1-3 microns in length, and is capable of motility via peritrichous flagella.

What would a positive result for the citrate slant look like?

Positive Reaction: Growth with color change from green to intense blue along the slant. Examples: Salmonella, Edwardsiella, Citrobacter, Klebsiella, Enterobacter, Serratia, Providencia, etc. Negative Reaction: No growth and No color change; Slant remains green.

Does Enterobacter aerogenes produce indole positive?

E. coli is indole-positive; Enterobacter aerogenes is indole- negative. Glucose is the major substrate oxidized by enteric bacteria for energy production.

Is Enterobacter aerogenes urease positive or negative?

aerogenes is nonmotile and urease positive (5).

What color is Enterobacter aerogenes?

pink
The fermentation oflactose by some Gram-negative rods produces acidic products that react with the dyes to produce colored colonies. Escherichia coli colonies produce a green, metallic sheen. Enterobacter aerogenes colonies are a pink/buff color with darker centers.

What does e aerogenes look like under a microscope?

Under the microscope, Enterobacter is rod-shaped with rounded ends. Enterobacter aerogenes and Enterobacter cloacae cause wound (Múñez et al 2012), respiratory (Wang et al 2012), and urinary tract infections (Edlin 2013). A drug-resistant strain of Enterobacter aerogenes has emerged (Karlowsky et al 2013).
