Providencia rettgeri strain PR_162 16

Providencia rettgeri strain PR_162 16 is a Gram-negative, rod-shaped bacterium classified as a chemoheterotroph, which indicates that it derives its energy and carbon from organic compounds. This organism is characterized as a facultative anaerobe, meaning it can grow in both the presence and absence of oxygen, and it possesses mobility due to the presence of flagella. The optimal growth temperature for P. rettgeri strain PR_162 16 is 37°C, which falls within the mesophilic range. This temperature preference aligns with its known hosts, which include Homo sapiens, Bos (cattle), various amphibians, specifically Bombina bombina, and serpents. The bacterium is nonsporulating and has a singular replicon structure. In terms of health effects, P. rettgeri strain PR_162 16 is associated with multisystem infections and is implicated in ventilator-associated pneumonia (VAP) in humans. This pathogenicity highlights its relevance in clinical settings, particularly in patients with compromised health or those requiring mechanical ventilation. The diverse habitat of P. rettgeri strain PR_162 16, along with its ability to infect multiple hosts, suggests it has a versatile ecological niche. Its role as a pathogen in humans underscores the importance of monitoring environmental sources of this bacterium, especially in healthcare environments where vulnerable populations may be at risk for infections. Understanding its characteristics and behaviors can aid in developing strategies for infection control and treatment.
