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.
This is a shortened version of the first chapter of the ICD-9: Infectious and Parasitic Diseases. It covers ICD codes 001 to 139. The full chapter can be found on pages 49 to 99 of Volume 1, which contains all (sub)categories of the ICD-9. Volume 2 is an alphabetical index of Volume 1.
Carbapenem-resistant Enterobacteriaceae (CRE) have been defined as carbapenem-nonsusceptible and extended-spectrum cephalosporin-resistant Escherichia coli, Enterobacter aerogenes, Enterobacter cloacae complex, Klebsiella pneumoniae, or Klebsiella oxytoca. Some exclude ertapenem resistance from the definition. [5]
Klebsiella species are known to also infect a variety of other animals, both as normal flora and opportunistic pathogens. [4] Klebsiella organisms can lead to a wide range of disease states, notably pneumonia, urinary tract infections, sepsis, meningitis, diarrhea, peritonitis and soft tissue infections.
It is known to cause wound infections and other species of its genera are known to cause urinary tract infections. P. vulgaris was one of the three species Hauser isolated from putrefied meat and identified (1885). Over the past two decades, the genus Proteus, and in particular P. vulgaris, has undergone a number of major taxonomic revisions.
Enterobacter is associated with common nosocomial infections including respiratory, endocarditis, bacteremia, urinary tract infections, osteomyelitis, among others. [8] Enterobacter bacteremia presents as fever but can progress to SIRS and shock. [8] For Enterobacter pneumonia, symptoms include coughing and shortness of breath. [8]
Members of genus Raoultella grow at 10 °C consistent with their recovery from plants, soil, and water, whereas members of Klebsiella do not grow at 10 °C [4] and are mainly recovered from mammals' mucosae. Klebsiella oxytoca is an exception, and a proposal to classify K. oxytoca in a separate, unnamed genus has been made. [5]
An indole test will differentiate Enterobacter from Escherichia, as Enterobacter are indole negative and Escherichia is positive. [5] Enterobacter are distinguished from Klebsiella because of their differences in motility. [5] Klebsiella are non-motile, Gram-negative bacilli ranging from 1–2 μm in length. [6]
