Acinetobacter baumannii strain AB127

Acinetobacter baumannii strain AB127 is a Gram-negative, rod-shaped bacterium that is classified as a chemoheterotroph, relying on organic compounds for energy. This strain is typically found in multiple habitats and is characterized by a single cell arrangement. As an aerobe, it requires oxygen for growth and lacks mobility, despite possessing flagella. AB127 thrives optimally at 37°C, which aligns with its mesophilic nature. It has a unique cellular structure, featuring two membranes and a single replicon. This bacterium is free-living, indicating that it does not depend on a host for survival, although it can infect various hosts, including humans (Homo sapiens), chickens (Gallus gallus), and cattle (Bos taurus and Bos). Clinically, A. baumannii strain AB127 is known for its pathogenicity in humans, being associated with severe health effects such as bacteremia, necrotizing fasciitis, bloodstream infections, urinary tract infections, and hospital-acquired pneumonia. It is notably involved in healthcare-associated infections, wound contaminations, and infections stemming from traumatic injuries. Its ability to thrive in diverse environments, coupled with its significant role in severe infections, underscores its importance in clinical microbiology and public health. Understanding its ecological dynamics can inform strategies to mitigate hospital-acquired infections and improve patient outcomes.
