Klebsiella aerogenes


K. aerogenesis a gram-negative, rod-shaped, motile bacterium common to the gastrointestinal tract of humans. It is generally not pathogenic in healthy individuals. K. aerogenes was originally classified as Enterobacter aerogenes until its recent reclassification.


These bacteria can cause illness, such as sepsis, in hospital settings or in otherwise immunocompromised individuals. Infection with K. aerogenes can be the result of certain antibiotic treatments, insertion of venous catheters, or surgical procedures.


K. aerogenes is susceptible to most antibiotics that are targeted for this type of bacteria; however, it has shown an ability to readily acquire resistance to antibiotics. This complicates the treatment of infections due to K. aerogenes, which usually require multiple alternating antibiotics.


K. aerogenes is gaining attention for its ability to produce hydrogen, a clean source of energy, in comparatively large quantities even in more acidic conditions.
