Klebsiella pneumoniae
Klebsiella pneumoniae (pronounced: kleb-see-el-uh noo-moh-nee-uh) is a type of bacteria that can cause different types of healthcare-associated infections, including pneumonia, bloodstream infections, wound or surgical site infections, and meningitis.
Etymology
The name Klebsiella pneumoniae is derived from the German microbiologist Edwin Klebs, who first isolated the bacterium in the 19th century. The term pneumoniae is derived from the Greek word pneumon, meaning lung, as this bacterium is often associated with lung infections.
Characteristics
Klebsiella pneumoniae is a Gram-negative, nonmotile, encapsulated, lactose-fermenting, facultative anaerobic, rod-shaped bacterium. It is often found in the human gut and can be a part of the normal gut microbiota. However, it can also become pathogenic and cause severe infections, especially in immunocompromised individuals.
Infections
Klebsiella pneumoniae can cause a range of diseases, depending on which part of the body it infects. It can cause pneumonia when it infects the lungs, meningitis when it infects the brain, septicemia when it enters the bloodstream, and urinary tract infection when it infects the urinary tract.
Treatment
Treatment of Klebsiella pneumoniae infections can be challenging due to the increasing emergence of antibiotic resistance. However, many strains remain susceptible to carbapenems, although carbapenem-resistant strains have also been reported.
Prevention
Prevention of Klebsiella pneumoniae infections involves good hygiene practices, such as regular handwashing, especially in healthcare settings. In hospitals, strict adherence to infection control practices, such as the use of personal protective equipment and isolation of infected patients, can help prevent the spread of this bacterium.
