Citrobacter koseri strain NCTC5055

Citrobacter koseri strain NCTC5055 is a Gram-negative, rod-shaped bacterium that exhibits facultatively anaerobic growth characteristics. This organism is motile, possessing flagella that enable movement. It thrives in mesophilic conditions, operating optimally within a temperature range typical for many environmental and host-associated bacteria. C. koseri is noted for its free-living biotic relationship, and it has been isolated from multiple habitats. It is known to interact with various hosts, including Homo sapiens and members of the Rodentia order. This strain is particularly relevant in clinical settings due to its pathogenicity in humans, being implicated in several serious health conditions. These include brain abscesses, meningitis, sepsis, urinary tract infections (UTIs), and infective aortic endocarditis, among others. The organism is also associated with community-acquired and catheter-associated urinary tract infections (CAUTI), highlighting its role in both hospital and community health concerns. C. koseri strain NCTC5055 is characterized by having a single replicon and a double membrane structure, typical of Gram-negative bacteria. The presence of this bacterium in clinical infections underlines its significance in medical microbiology and public health, particularly as it can result in severe and sometimes life-threatening conditions. Understanding the ecological presence and pathogenic potential of C. koseri is essential for developing effective prevention and treatment strategies in both healthcare settings and broader ecological contexts.
