Klebsiella is a genus of Gram-negative, oxidase-negative, rod-shaped bacteria with a prominent polysaccharide-based capsule.

Is Klebsiella aerogenes Gram positive?

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.

Does e Aerogenes have a capsule?

E. aerogenes are smaller, rod-shaped cells that are motile and encapsulated compared to others in the same family of Enterobacteriaceae.

What is capsule stain?

Capsule stain is a type of differential stain which uses acidic and basic dyes to stain background & bacterial cells respectively so that presence of capsule is easily visualized. Capsule is synthesized in the cytoplasm and secreted to the outside of the cell where it surrounds the bacterium.

What stains are used for capsule staining?

The capsule stain employs an acidic stain and a basic stain to detect capsule production….Procedure of Capsule Staining

  • Place a small drop of a negative stain (India Ink, Congo Red, Nigrosin, or Eosin) on the slide.
  • Using sterile technique, add a loopful of bacterial culture to slide, smearing it in the dye.

Is e Aerogenes indole positive?

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

What does Klebsiella aerogenes cause?

When these bacteria get into other areas of the body, they can cause infection. These infections could include: urinary tract infections; • pneumonia; • bloodstream infections (also called sepsis); • wound or surgical site infections; and • meningitis.

What causes e Aerogenes?

Enterobacter aerogenes can cause gastrointestinal infections, urinary tract infections (UTIs), skin and soft tissue infections, respiratory infections, and adult meningitis.
