Klebsiella variicola strain ST681 102

Klebsiella variicola strain ST681 102 is a Gram-negative, facultative anaerobic bacterium characterized by its rod shape and ability to move due to the presence of flagella. This strain is typically found in host-associated environments, indicating a symbiotic relationship with various hosts, including Homo sapiens (humans), Ovis aries (sheep), Metazoa (multicellular animals), and certain annelids such as Aporrectodea sp. and Metaphire sieboldi. The bacterium exhibits a distinct cell arrangement, frequently found in chains, pairs, and singles. It thrives optimally at 37°C, within a mesophilic temperature range. Importantly, Klebsiella variicola strain ST681 102 is nonsporulating and possesses a singular replicon and a double membrane structure, typical of Gram-negative bacteria. This strain is associated with significant health effects, particularly in humans, where it can lead to bloodstream and urinary tract infections. The ability to establish a symbiotic relationship with various hosts suggests a potential ecological role in the microbiota of these organisms. The presence of K. variicola in both human and animal hosts underscores its relevance in understanding microbial interactions and pathogenicity, particularly in clinical settings. The data indicate that K. variicola strain ST681 102 may contribute to the dynamics of host-associated microbial communities, impacting both health and disease outcomes in its diverse range of hosts.
