Klebsiella pneumoniae. Klebsiella pneumoniae is a Gram-negative, non-motile, encapsulated, lactose - fermenting, facultative anaerobic, rod-shaped bacterium. It appears as a mucoid lactose fermenter on MacConkey agar. Although found in the normal flora of the mouth, skin, and intestines, [1] it can cause destructive changes to human and animal ...
Klebsiella variicola. Klebsiella is a genus of Gram-negative, oxidase-negative, rod-shaped bacteria with a prominent polysaccharide -based capsule. [3] Klebsiella is named after German-Swiss microbiologist Edwin Klebs (1834–1913). Carl Friedlander described Klebsiella bacillus which is why it was termed Friedlander bacillus for many years.
Atypical bacteria causing pneumonia are Coxiella burnetii, Chlamydophila pneumoniae (J16.0), Mycoplasma pneumoniae (J15.7), and Legionella pneumophila. The term "atypical" does not relate to how commonly these organisms cause pneumonia, how well it responds to common antibiotics or how typical the symptoms are; it refers instead to the fact ...
Klebsiella aerogenes, [ 2 ] previously known as Enterobacter aerogenes, is a Gram-negative, oxidase -negative, catalase -positive, citrate -positive, indole -negative, rod-shaped bacterium. [ 3 ] Capable of motility via peritrichous flagella, [ 4 ] it is approximately one to three microns in length. Klebsiella aerogenes is a nosocomial ...
Klebsiella oxytoca is a Gram-negative, rod-shaped bacterium that is closely related to K. pneumoniae, from which it is distinguished by being indole-positive; it also has slightly different growth characteristics in that it is able to grow on melezitose, but not 3-hydroxybutyrate. It was first described in 1886 when it was isolated from sour ...
Klebsiella pneumoniae is the most common Klebsiella species found in humans, the gastrointestinal tracts of animals, in sewage and in soil. [7] On carbohydrate-rich media, Klebsiella colonies appear greyish-white in colour with a mucosal outer surface. [6]
A 2008 study at Mount Sinai identified outcomes associated with Carbapenem-resistant Klebsiella pneumoniae infections, in which patients in need of organ or stem cell transplants, mechanical ventilation, prolonged hospitalization, or prior treatment with carbapenems, had an increased probability of infection with Carbapenem-resistant K ...
New Delhi metallo-beta-lactamase 1. Klebsiella pneumoniae, the bacterium in which NDM-1 was first identified. NDM-1[1] is an enzyme that makes bacteria resistant to a broad range of beta-lactam antibiotics. These include the antibiotics of the carbapenem family, which are a mainstay for the treatment of antibiotic-resistant bacterial infections.
