Raoultella ornithinolytica strain JUb54

Raoultella ornithinolytica strain JUb54 is a Gram-negative, rod-shaped bacterium classified as a chemoheterotroph. This strain is a facultative anaerobe, capable of thriving in both the presence and absence of oxygen. It does not exhibit mobility but does possess flagella, which may play a role in its interactions within various environments. This bacterium is mesophilic, with an optimal growth temperature of 37°C, indicating it can effectively proliferate in conditions similar to human body temperature. Raoultella ornithinolytica strain JUb54 has been found in multiple habitats, suggesting a versatile ecological niche. Its hosts include Homo sapiens, various insect species, Ixodida (ticks), Termitoidae (termites), and the plant Crinum macowanii. Clinically, this strain is associated with several health issues, including bacteremia, human infections, abdominal abscesses, sepsis, cholecystitis, and gallbladder perforation. These health effects highlight the pathogenic potential of R. ornithinolytica in humans, particularly concerning abdominal and systemic infections that can lead to severe complications such as multiple organ failure and fish poisoning. The presence of this bacterium in both human hosts and diverse ecological niches underscores its role as an opportunistic pathogen. Its ability to thrive in various environments and its association with significant health risks indicate that R. ornithinolytica strain JUb54 warrants further investigation to better understand its ecological impact and implications for public health.
