Acinetobacter baumannii strain Ab13

Acinetobacter baumannii strain Ab13 is a Gram-negative, rod-shaped bacterium that thrives as a free-living organism, showcasing its adaptability to multiple habitats. As a chemoheterotroph, it derives energy from organic compounds, primarily utilizing an aerobic metabolism, which indicates its requirement for oxygen to survive and grow. This organism is non-motile and possesses flagella, suggesting potential mechanisms for surface adherence rather than motility. Ab13 is mesophilic, with an optimal growth temperature of 37°C, which aligns with the human body temperature, facilitating its role as a human pathogen. It is noted for its pathogenic effects, contributing to a range of severe infections, including bacteremia, necrotizing fasciitis, bloodstream infections, urinary tract infections, nosocomial infections, hospital-acquired pneumonia, and respiratory tract infections. Additionally, it is associated with wound contaminations and can cause both healthcare-associated and community-acquired infections. The strain is characterized by a single replicon and two membranes, typical of Gram-negative bacteria, which may contribute to its resilience and ability to evade certain antimicrobial treatments. Notably, it can infect various hosts, including humans (Homo sapiens), chickens (Gallus gallus), and cattle (Bos taurus and Bos), demonstrating a broad ecological niche. The presence of Acinetobacter baumannii in diverse environments and its significant health impacts underscore its importance in clinical microbiology, particularly in the context of antibiotic resistance and hospital infections, highlighting the need for ongoing surveillance and research to combat its pathogenicity.
