Acinetobacter baumannii strain I43

Acinetobacter baumannii strain I43 is a Gram-negative, rod-shaped bacterium characterized as a heterotrophic chemoheterotroph. It thrives in various habitats and is classified as a free-living organism. This strain exhibits an aerobic oxygen requirement, lacking mobility, yet possesses flagella. The optimal growth temperature for A. baumannii strain I43 is 37°C, situating it within the mesophilic temperature range. Notably, A. baumannii strain I43 has significant medical implications due to its pathogenicity in humans. It is associated with a range of severe health effects, including bacteremia, necrotizing fasciitis, bloodstream infections, urinary tract infections, and hospital-acquired pneumonia. Additionally, it can lead to traumatic injuries and respiratory tract infections, further contributing to healthcare-associated infections. The bacterium can also cause community-acquired infections, showcasing its versatility as a pathogen. Genetically, A. baumannii strain I43 has two replicons and two membranes, which is characteristic of its structure and function as a Gram-negative organism. The presence of multiple membranes may confer advantages in resisting certain antibiotics, complicating treatment options for infections it causes. Overall, the ecological role of A. baumannii strain I43 is underscored by its ability to adapt to diverse environments while posing significant health risks, particularly in hospital settings. Its pathogenic potential and resistance mechanisms highlight the need for continued surveillance and research to manage infections effectively.
