Klebsiella pneumoniae subsp. pneumoniae strain 61

Klebsiella pneumoniae subsp. pneumoniae strain 61 is a Gram-negative, rod-shaped bacterium known for its role in causing pneumonia, particularly community-acquired pneumonia (CAP). This strain is classified as a chemoheterotroph, indicating that it derives energy from organic compounds, and it is capable of existing in various cellular arrangements, including chains, pairs, and singles. As a facultative anaerobe, strain 61 can thrive in the presence or absence of oxygen, further demonstrating its adaptability to different environments. Its optimal growth temperature is 37°C, aligning with the typical human body temperature, which is relevant considering its association with human disease. The strain is mesophilic, indicating it thrives in moderate temperature ranges. Klebsiella pneumoniae subsp. pneumoniae strain 61 possesses flagella, indicating motility, which may aid in its pathogenicity and colonization within host tissues. It has a simple genetic structure, characterized by a single replicon, and is surrounded by two membranes, typical of Gram-negative bacteria. Notably, this strain is nonsporulating, which means it does not form spores, a trait that affects its survival strategies in various environments. In terms of ecological impact, the free-living nature of this bacterium suggests it can inhabit diverse environments outside of a host, potentially influencing microbial communities and contributing to the spread of antibiotic resistance. Understanding the traits of Klebsiella pneumoniae subsp. pneumoniae strain 61 can aid in developing strategies to combat infections and manage its presence in both clinical and environmental contexts.
