Klebsiella pneumoniae is a bacterium that normally lives inside the intestines and colonizes the mucous membranes of the upper respiratory tract of humans and blood-blooded animals without causing problems
However, this germ can cause a wide range of infections, mainly nosocomial or in vulnerable subjects (diabetics, alcoholics), including pneumonia, wound infection, blood, urinary tract infections or meningitis.
It is a Gram-negative, rod-shaped, nonmotile, encapsulated bacterium that belongs to the Klebsiella genus of Enterobacteriaceae.
Klebsiella pneumoniae can be treated with antibiotics, but the increase in antibiotic-resistant strains of bacteria has reduced the choices available to doctors.
Klebsiella pneumoniae is hand-borne, which means that this bacterium can be transmitted through person-to-person skin contact (caregiver hands), through contaminated objects or surfaces. The bacteria do not spread through the air.
In hospital settings, patients may also be exposed to K. pneumoniae when they are on ventilators (breathing machines) or have intravenous or ureteral catheters or wounds (injury or surgery).
The infection can develop from germs carried by the patient himself.
Symptoms and treatment for Klebsiella pneumoniae infection differ depending on where the infection is located (blood, meninges, wound). It is the cause of many ailments, including:
According NCBI Taxonomy Browser, The species Klebsiella pneumoniae belongs to the order Enterobacterales, the family Enterobacteriaceae and the genus Klebsiella.
It was first described in 1882 by Carl Friedlander and initially named Friedlander's bacillus, it was not until 1886 that the bacterium was given the name Klebsiella in honor of microbiologist Edwin Klebs.
