Klebsiella pneumoniae subsp. pneumoniae strain 64

Klebsiella pneumoniae subsp. pneumoniae strain 64 is a Gram-negative, rod-shaped bacterium that is classified as a facultative anaerobe and a chemoheterotroph. This strain typically inhabits host-associated environments and exhibits a diverse cell arrangement, appearing in chains, pairs, and singles. It possesses flagella, which contributes to its mobility, allowing it to navigate through various environments effectively. The optimal growth temperature for this strain is 37°C, positioning it within the mesophilic temperature range, which is conducive to the survival and replication of many pathogenic microorganisms. Notably, Klebsiella pneumoniae subsp. pneumoniae strain 64 is nonsporulating, meaning it does not form spores as a survival mechanism, which is characteristic of some other bacteria. This strain is associated with significant health effects, particularly in causing pneumonia and community-acquired pneumonia (CAP), making it a notable pathogen in clinical settings. Its ability to thrive in host-associated environments while being free-living highlights its ecological versatility. With a single replicon and a double membrane structure, the strain's cellular organization is consistent with that of many other members of the Enterobacteriaceae family. The pathogenicity of Klebsiella pneumoniae subsp. pneumoniae strain 64, combined with its environmental adaptability, underscores the importance of monitoring and understanding its behavior in both clinical and ecological contexts.
