Citrobacter freundii strain AR_0116

Citrobacter freundii strain AR_0116 is a Gram-negative, rod-shaped bacterium that demonstrates facultative anaerobic growth, indicating its ability to thrive in both aerobic and anaerobic environments. This strain is equipped with flagella, enabling motility. It has been identified in various habitats, including hospital sewage, intestinal tracts, sewage systems, soil, and surface waters, showcasing its adaptability to diverse ecosystems. Notably, C. freundii strain AR_0116 has been associated with opportunistic infections in humans and animals. In humans, it is linked to infections of the urinary and respiratory tracts. In veterinary contexts, it is known to cause respiratory tract and wound infections in horses, as well as respiratory infections in dogs and urinary tract infections in cats. Additionally, it has been implicated in infections across a wide range of hosts, including various mammals and amphibians, such as Homo sapiens, Canis lupus familiaris, and Gastrotheca riobambae. The strain has three replicons, suggesting a complex genomic structure that may contribute to its pathogenic potential and adaptability. The presence of C. freundii in both hospital sewage and environmental sources emphasizes its role in the microbiome of both human and animal health. This bacterium's ability to inhabit such varied environments, along with its potential to cause infections, underscores its significance in clinical microbiology and public health. Understanding its ecology and pathogenicity is essential for developing strategies to manage its impact on health and the environment.
