Citrobacter koseri strain NCTC10810

Citrobacter koseri strain NCTC10810 is a Gram-negative, rod-shaped bacterium that falls under the category of facultatively anaerobes, indicating its ability to thrive in both aerobic and anaerobic environments. This strain is mesophilic, meaning it grows optimally within a moderate temperature range. It possesses flagella, allowing for mobility, and has a unique cellular architecture characterized by two membranes and a single replicon. C. koseri is notably free-living but has significant pathogenic potential in humans and rodents, acting as an opportunistic pathogen. It is associated with various serious health complications, including brain abscesses, meningitis, and sepsis. Moreover, it is implicated in urinary tract infections, specifically catheter-associated urinary tract infections (CAUTI) and community-acquired UTIs, as well as infective aortic endocarditis. The bacterium's ability to cause multiple brain abscesses further highlights its pathogenicity. Ecologically, the presence of C. koseri in both human and rodent hosts suggests a versatile adaptability, allowing it to thrive in diverse environments. Its pathogenic capabilities in humans, particularly in immunocompromised individuals or those with underlying health conditions, underscore its role as a significant concern in clinical microbiology. Understanding the traits of Citrobacter koseri NCTC10810 can aid in developing strategies for prevention and treatment of the infections it causes.
