What does Klebsiella look like on agar?

Laboratory Identification of Klebsiella pneumoniae colonies are pink (LF), mucoid (usually), and 3 to 4 mm in diameter. Colonies on Hektoen enteric agar and XLD are yellow. Large, mucoid, glistening pink colonies on a MacConkey agar plate, typical of the colonies produced by many Klebsiella and Enterobacter spp.

What agar does Klebsiella grow on?

The Eosin Methylene Blue Agar (EMB Agar) medium which is the Selective medium for Klebsiella pneumoniae contains Eosin dye and Methylene Blue dye which inhibits the growth of many gram-positive bacteria, inhibits the growth of Shigella and Salmonella species and supports the growth of Klebsiella pneumoniae.

Does Klebsiella grow on blood agar?

In Blood Agar medium, the Klebsiella pneumoniae colonies are non-hemolytic i.e. shows Gamma Hemolysis (γ-hemolysis). In MacConkey Agar medium, the colonies of Klebsiella pneumoniae are pink colored due to the lactose fermentation which is of great importance in differentiating K.

What are the characteristics of Klebsiella?

Klebsiella is a Gram-negative, non-motile, and rod-shaped bacteria. The bacterium has a capsule; it is resistant to the environment and action of disinfectants as well as many antibiotics, which makes it lethal.

How did I get Klebsiella?

Klebsiella bacteria are mostly spread through person-to-person contact. Less commonly, they are spread by contamination in the environment. As with other healthcare-associated infections, the bacteria can be spread in a health care setting via the contaminated hands of health care workers.

What antibiotic kills Klebsiella?

If Klebsiella pneumonia is acquired in the community, antibiotics, usually a cephalosporin (such as ceftriaxone) or fluoroquinolone (such as levofloxacin), given intravenously, can cure it.

Is Klebsiella a gram negative rod?

Klebsiella [kleb−see−ell−uh] is a type of Gram-negative bacteria that can cause different types of healthcare-associated infections, including pneumonia, bloodstream infections, wound or surgical site infections, and meningitis.

Is Klebsiella catalase positive or negative?

Klebsiella pneumoniae is a gram negative, non-motile, encapsulated, lactose fermenting, facultative anaerobe, catalase positive, oxidase negative belonging to the Enterobacteriaceae family (Elmer et al., 2006; Hind, et al., 2016). It is the most common causative agent of nosocomial and community acquired infections.

Is Klebsiella a Gram-negative rod?

Where is Klebsiella found in the body?

Klebsiella bacteria are normally found in the human intestines (where they do not cause disease). They are also found in human stool (feces). In healthcare settings, Klebsiella infections commonly occur among sick patients who are receiving treatment for other conditions.
