Providencia rettgeri

Providencia rettgeri is a Gram-negative, rod-shaped bacterium characterized by its motility, which is facilitated by the presence of true flagella. As a facultative anaerobe, P. rettgeri can thrive in both aerobic and anaerobic environments, exhibiting a mesophilic temperature classification with an optimal growth temperature of 37.0 °C. This bacterium is classified as a chemoheterotroph, meaning it derives energy from organic compounds. P. rettgeri is nonsporulating and demonstrates a complex genomic structure, possessing four replicons, which may contribute to its adaptability in various habitats. The species has been identified as pathogenic to humans, although specific pathogenic mechanisms are not detailed within the available data. Its ability to inhabit multiple environments suggests a versatile ecological niche, potentially influencing its interactions within microbial communities. In summary, the physiological traits of Providencia rettgeri indicate its adaptability and potential role in human health, reflecting the broader implications of its presence in various ecological contexts.
