Klebsiella pneumoniae strain NCTC9617

Klebsiella pneumoniae strain NCTC9617 is a Gram-negative, rod-shaped bacterium characterized as a facultative anaerobe and a chemoheterotroph. This organism demonstrates mobility, facilitated by the presence of flagella, and typically exists in various arrangements, including chains, pairs, and singles. The strain thrives optimally at a temperature of 37°C, placing it within the mesophilic range. As a host-associated bacterium, K. pneumoniae NCTC9617 has been identified in multiple hosts, including Homo sapiens, various avian species (Phasianidae, Gallus gallus), mammals (Canis lupus familiaris, Sus scrofa, Ovis aries, Equidae), and aquatic organisms (Danio rerio, Amphibia). This broad host range indicates its ecological adaptability. Clinically, K. pneumoniae NCTC9617 is significant due to its association with a variety of health effects in humans, including bacteremia, urinary tract infections, pneumonia, and sepsis, among others. The strain is known for causing both community-acquired and healthcare-associated infections. Its pathogenic abilities highlight its role as a human pathogen, leading to severe health complications when it infects susceptible individuals. The ecological insight derived from the diverse hosts and pathogenic capabilities of K. pneumoniae NCTC9617 suggests that it can thrive in varied environments, potentially contributing to its persistence in both natural and clinical settings. Its ability to cause a wide range of infections underscores the importance of monitoring and understanding this bacterium within microbial populations and public health contexts.
