Citrobacter freundii strain ICR003203

Citrobacter freundii strain ICR003203 is a Gram-negative, facultative anaerobic bacterium characterized by its rod-shaped morphology and the presence of flagella. This strain has been isolated from diverse habitats, including hospital sewage, intestinal tracts, sewage systems, soil, and surface waters. The strain contains a single replicon and has been associated with various hosts, including Homo sapiens, multiple animal species such as rabbits (Oryctolagus cuniculus), dogs (Canis lupus familiaris), cats (Felis catus), as well as fish like Tilapia and Cyprinus carpio. C. freundii is known to be an opportunistic pathogen, capable of causing infections in both humans and animals. In humans, it can lead to infections of the urinary and respiratory tracts, while in animals, it has been documented to cause respiratory tract and wound infections in horses, as well as pleuritis and urinary tract infections in cats. Dogs can also experience respiratory tract infections due to this bacterium. The presence of C. freundii in various environments, including hospital sewage, suggests its potential role in the dissemination of antibiotic resistance and its adaptation to human-associated habitats. Its diverse host range indicates that it can thrive in different ecological niches, highlighting its opportunistic nature. Understanding the ecological distribution and pathogenic potential of this strain can provide insights into the risks associated with its presence in clinical and environmental settings.
