Providencia rettgeri strain NCTC7476

Providencia rettgeri strain NCTC7476 is a Gram-negative, rod-shaped bacterium characterized as a chemoheterotroph and a facultative anaerobe, indicating its ability to utilize organic compounds for energy and adapt to varying oxygen levels. This strain is motile, possessing flagella, which facilitates its movement in diverse environments. Optimal growth occurs at 37°C, positioning it within the mesophilic temperature range, suitable for survival in warm-blooded hosts. Notably, P. rettgeri has been identified in various habitats, which underscores its ecological versatility. This bacterium is known to infect multiple hosts, including humans (Homo sapiens), domestic animals like cattle (Bos), amphibians (Amphibia), specifically the fire-bellied toad (Bombina bombina), and reptiles (Serpentes), highlighting its potential as a pathogen across different biological classes. In humans, P. rettgeri is associated with multisystem infections and is a known contributor to ventilator-associated pneumonia (VAP), underscoring its pathogenicity in clinical settings. Its presence in healthcare-associated infections emphasizes the need for vigilance in monitoring and managing infections caused by this organism. Overall, the ecological adaptability of Providencia rettgeri, coupled with its pathogenic potential in various hosts, suggests that it plays a significant role in both environmental microbiology and clinical microbiology, warranting further investigation into its epidemiology and mechanisms of infection.
