Klebsiella pneumoniae subsp. pneumoniae strain UCO-490

Klebsiella pneumoniae subsp. pneumoniae strain UCO-490 is a Gram-negative, rod-shaped bacterium that is classified as a chemoheterotroph, meaning it derives its energy from organic compounds. This strain typically exists in a host-associated habitat, indicating a close relationship with its host organisms. It is characterized by a variety of cell arrangements, including chains, pairs, and singles, and possesses flagella, which contribute to its mobility. UCO-490 is a facultative anaerobe, allowing it to thrive in both aerobic and anaerobic environments. Its optimal growth temperature is 37°C, placing it in the mesophilic range, which is conducive for growth in warm-blooded hosts. The strain contains a single replicon and is structured with two membranes, a typical feature of Gram-negative bacteria. In terms of health impacts, Klebsiella pneumoniae subsp. pneumoniae strain UCO-490 is known to be associated with pneumonia, particularly community-acquired pneumonia (CAP), posing a significant risk in clinical settings. The bacterium is nonsporulating, which means it does not form spores as a means of survival under adverse conditions. From an ecological perspective, the free-living nature of this strain suggests it may play a role in microbial communities within its host environments. Its ability to cause disease, combined with its diverse cell arrangements and mobility, underscores the importance of monitoring Klebsiella pneumoniae in both clinical and ecological studies to understand its behavior and impact on health.
