Acinetobacter baumannii strain Ab28

Acinetobacter baumannii strain Ab28 is a Gram-negative, rod-shaped bacterium that exists as a free-living organism in multiple habitats. It is classified as a chemoheterotroph, relying on organic compounds for energy. This strain is aerobic, requiring oxygen for its metabolic processes, and it does not exhibit mobility as it lacks flagella, despite their presence in its cellular structure. The optimal growth temperature for A. baumannii Ab28 is 37°C, placing it within the mesophilic temperature range that is conducive to growth in human and animal hosts. This strain has a single replicon and is characterized by its double membrane structure. Acinetobacter baumannii strain Ab28 is known for its pathogenicity, particularly in humans, and is associated with various severe health effects such as bacteremia, necrotizing fasciitis, bloodstream infections, urinary tract infections, nosocomial infections, hospital-acquired pneumonia, traumatic injuries, respiratory tract infections, and wound contaminations. It can also be involved in community-acquired infections, highlighting its versatility as a pathogen. The strain's ability to inhabit diverse environments and its association with multiple hosts—including humans (Homo sapiens), chickens (Gallus gallus), and cattle (Bos taurus)—suggests a significant ecological adaptability. This adaptability may contribute to its persistence in healthcare settings, where it has been linked to various healthcare-associated infections. Understanding these traits is crucial for developing effective control measures and treatment strategies for infections caused by A. baumannii.
