December 2015; Acta biochimica Polonica 62(4) DOI: 10.18388/abp.2015_1148. Authors: Esra Deniz Candan. Some important virulence factors have been elucidated in Klebsiella pneumoniae infections. A critical trait of K. pneumoniae that has enabled its ongoing evolution is the ability to acquire new genetic material. Klebsiella pneumoniae on Blood Agar. Tel. 6001, 86051-970, Londrina, PR, Brazil. pneumoniae is reported to be the second most common cause of Gram-negative bacteremia and has a high mortality … Klebsiella pneumoniae is a frequent cause of infectious diseases in hospitals and community settings and is associated with a wide variety of clinical conditions including pneumonia, intra-abdominal infections, urinary tract infections, and bloodstream infections (BSIs).K. Although hypervirulent Klebsiella pneumoniae (hvKp) has been associated with severe community-acquired infections that occur among relatively healthy individuals, information about hvKp infections in health care settings remains limited. Klebsiella pneumoniae is an increasingly important bacterial pathogen that is capable of causing severe organ and life-threatening disease. characteristics. In humans, K.pneumoniae is concentrated in the gastrointestinal tract, and a few in the nasopharynx, through which the bacteria can enter the blood circulation or other tissues, and then cause infection.
