Klebsiella aerogenes strain NCTC8846

Klebsiella aerogenes strain NCTC8846 is a Gram-negative, rod-shaped bacterium characterized as a chemoheterotroph and a facultative anaerobe, thriving optimally at 37°C within a mesophilic temperature range. This strain does not exhibit mobility, as it lacks flagella, yet it possesses two replicons, indicating a complex genomic structure. K. aerogenes is known to inhabit multiple environments, which contributes to its versatility and ability to infect a variety of hosts. Documented hosts include Homo sapiens, various insect species, Ixodida (ticks), Termitoidae (termites), and the plant Crinum macowanii. This broad host range underscores the bacterium's ecological adaptability and its potential role in various biological interactions. In terms of health implications, K. aerogenes strain NCTC8846 is associated with several serious health conditions in humans. These include bacteremia, abdominal infections, sepsis, cholecystitis, and even complications such as gallbladder perforation and multiple organ failure. The bacterium's capacity to cause abdominal abscesses and fish poisoning further highlights its pathogenic potential. Understanding the ecological versatility and pathogenicity of K. aerogenes is crucial, particularly in clinical settings where it can lead to severe infections. Its presence across diverse hosts and environments emphasizes the importance of monitoring this bacterium in both medical and ecological contexts.
