Citrobacter freundii strain 2016WA-SCV

Citrobacter freundii strain 2016WA-SCV is a Gram-negative, facultative anaerobic bacterium exhibiting a rod-shaped morphology and possessing flagella. It is notable for its presence in diverse environments such as hospital sewage, intestinal tracts, various soils, and surface waters. This strain has been identified in a wide array of hosts, including Homo sapiens, various metazoans, and several animal species, such as Oryctolagus cuniculus (rabbits), Canis lupus familiaris (dogs), and Felis catus (cats), among others. C. freundii is recognized for its role as an opportunistic pathogen, capable of causing infections in both humans and animals. In humans, it is associated with urinary and respiratory tract infections, while in animals, it can lead to respiratory tract infections in dogs, pleuritis and urinary tract infections in cats, and infections in horses. Given its ability to thrive in hospital sewage and other contaminated environments, this strain poses a risk for healthcare-associated infections. Notably, C. freundii strain 2016WA-SCV nonsporulating characteristic indicates it does not form spores, which may influence its survival strategies in various habitats. The presence of this bacterium in the gut metagenome and its association with multiple host species suggest a complex ecological role, potentially impacting both health and disease dynamics in these organisms. This underscores the importance of monitoring such pathogens in environmental and clinical settings to mitigate health risks.
