Providencia rettgeri strain PR002

Providencia rettgeri strain PR002 is a Gram-negative, rod-shaped bacterium that exhibits mobility due to the presence of flagella. As a facultative anaerobe, it can thrive in both aerobic and anaerobic environments, demonstrating its adaptability to various habitats. This strain is categorized as a chemoheterotroph, indicating that it derives its energy from organic compounds. The optimal growth temperature for Providencia rettgeri strain PR002 is 37°C, positioning it within the mesophilic temperature range, which is conducive to its survival in warm-blooded hosts. This strain has been isolated from multiple habitats and has shown pathogenic potential primarily in humans, where it is associated with multisystem infections and ventilator-associated pneumonia (VAP). Additionally, it can infect other hosts, including Bos (cattle), amphibians, and serpents, as well as the specific amphibian Bombina bombina. Notably, strain PR002 does not form spores, which suggests that its survival strategies may rely on other mechanisms rather than sporulation. The strain has a single replicon, as indicated by its accession number NXKD00000000.1, which may reflect its genetic organization and replication capabilities. The presence of Providencia rettgeri in diverse hosts and its pathogenic effects highlight its ecological role and the potential health risks it poses in clinical settings, particularly in immunocompromised individuals. Understanding the biology and ecology of this strain can aid in the development of targeted interventions to manage infections associated with it.
