What is Klebsiella pneumoniae carbapenemase?
Klebsiella pneumoniae carbapenemase (KPC)-producing bacteria are a group of emerging highly drug-resistant Gram-negative bacilli causing infections associated with significant morbidity and mortality.
Why do colonies of Klebsiella pneumoniae appear mucoid when cultured?
Klebsiella are ubiquitous and may colonize the skin, pharynx, or gastrointestinal tract in humans. They form large moist colonies due to “large mucoid polysaccharide capsule (K antigen) that protects from phagocytosis and aids in adherence” (U of Maryland).
What does Klebsiella pneumoniae produce?
When bacteria such as Klebsiella pneumoniae produce an enzyme known as a carbapenemase (referred to as KPC-producing organisms), then the class of antibiotics called carbapenems will not work to kill the bacteria and treat the infection.
How do you know if you have Klebsiella?
Colonies that are mucoid on blood agar, appear as Gram- negative rods under the light microscope after staining, and are lactose- fermenting mucoid colonies in MacConkey’s and CLED agar are identified as 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.
What are the signs and symptoms of Klebsiella pneumoniae?
Klebsiella pneumoniae symptoms
- fever.
- chills.
- coughing.
- yellow or bloody mucus.
- shortness of breath.
- chest pain.
What is the average size of Klebsiella?
Klebsiella is a non-spore-forming, non-motile, facultative anaerobic Gram-negative straight rod, 0.3–1.0 μm in diameter and 0.6–6.0 μm in length. The rods are arranged singly, in pairs or in short chains. The cells are capsulated. The optimal temperature for growth is 37°C.
Are there different types of Klebsiella?
Klebsiella pneumoniae
Klebsiella oxytocaKlebsiella granulomatisKlebsiella terrigena
Klebsiella/Lower classifications
Three species in the genus Klebsiella are associated with illness in humans: Klebsiella pneumoniae, Klebsiella oxytoca, and Klebsiella granulomatis.
What is the morphology of a Klebsiella pneumoniae?
MORPHOLOGY OF KLEBSIELLA PNEUMONIAE (K. PNEUMONIAE) Shape – Klebsiella pneumoniae is a short, plump, straight rod shape (bacillus) bacterium. Size – The size of Klebsiella pneumoniae is about 1–2 µm × 0.5–0.8 µm (micrometer). Arrangement Of Cells – K. pneumoniae is arranged singly, in pairs, or in short chains and sometimes in clusters.
Are there any new strains of Klebsiella pneumoniae?
New antibiotic resistant strains of K. pneumoniae are appearing, and it is increasingly found as a nosocomial infection. Klebsiella ranks second to E. coli for urinary tract infections in older persons.
Which is the best Culture Media for Klebsiella pneumoniae?
⇒ There are various culture media used for the cultivation of Klebsiella pneumoniae in the laboratory and most commonly the Nutrient Agar medium and MacConkey Agar medium is used, the other media are as follows – Eosin Methylene Blue Agar (EMB Agar) Medium. The liquid medium ( Nutrient Broth medium, TSB medium, etc.).
How to tell if Klebsiella pneumoniae is lactose positive?
Images of K.pneumoniae. Klebsiella peumoniae treatment and antibiotics used for K.pneumoniae infections. Three different strains of Klebsiella pneumoniae on Endo agar with biochemical slope (see here). Klebsiella pneumoniae in detail left down side of each plate) and is lactose positive (but on Endo agar its colonies often remain quite pale).
