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.
Klebsiella oxytoca is an exception, and a proposal to classify K. oxytoca in a separate, unnamed genus has been made. [5] It consists of species Raoultella electrica, Raoultella ornithinolytica, Raoultella planticola and Raoultella terrigena. [6] In human infections, Raoultella species are generally sensitive to treatment with carbapenems. In ...
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.
Infections with carbapenem-resistant Klebsiella pneumoniae were associated with organ/stem cell transplantation, mechanical ventilation, exposure to antimicrobials, and overall longer length of stay in hospitals. [10] People most likely to acquire carbapenem-resistant bacteria are those already receiving medical attention. [10]
The genus Klebsiella was named after the German microbiologist Edwin Klebs (1834–1913). [citation needed] It is also known as Friedlander's bacillum in honor of Carl Friedländer, a German pathologist, who proposed that this bacterium was the etiological factor for the pneumonia seen especially in immunocompromised individuals such as people with chronic diseases or alcoholics.
Rhinoscleroma, is a chronic granulomatous bacterial disease of the nose that can sometimes infect the upper respiratory tract. [1] It most commonly affects the nasal cavity—the nose is involved in 95–100 per cent of cases—however, it can also affect the nasopharynx, larynx, trachea, and bronchi.
A strain of Raoultella planticola, Cd-1 has been found which grows anaerobically at high aqueous cadmium concentrations and precipitates insoluble cadmium sulfide.This strain has been isolated from reducing salt marsh sediments and may be useful in bioremediation of cadmium from exposed soils.
Klebsiella michiganensis is a species of bacteria in the genus Klebsiella and is one of the nine species in the Klebsiella oxytoca complex. [1] It is closely related to the species K. oxytoca except K. michiganensis is negative in the pectin degradation test and negative by PCR for polygalacturonase gene pehX. [1]
