Acinetobacter baumannii strain AB149

Acinetobacter baumannii strain AB149 is a notable Gram-negative bacterium characterized by its rod shape and lack of mobility. It is a chemoheterotrophic organism, deriving its energy from organic compounds, and is classified as an aerobe, indicating that it requires oxygen for growth. This strain is mesophilic, with an optimal growth temperature of 37°C, which aligns with the average human body temperature. AB149 is free-living and has a biotic relationship with various hosts, including Homo sapiens (humans), Gallus gallus (chickens), and Bos taurus (cattle). The bacterium possesses two membranes and has a single replicon, which contributes to its metabolic processes. Notably, it has flagella, which may play a role in its motility, although the strain itself is classified as non-motile. Pathogenically, Acinetobacter baumannii strain AB149 is of significant concern in healthcare settings, associated with a range of severe infections, including bacteremia, necrotizing fasciitis, and various hospital-acquired infections such as pneumonia and urinary tract infections. Its ability to cause both community-acquired and healthcare-associated infections highlights its adaptability and resilience in different environments. The ecological insight gleaned from the traits of AB149 underscores its role as an opportunistic pathogen in humans, particularly in hospital settings where it can thrive. Its adaptability to multiple habitats and diverse hosts reflects its potential impact on public health, especially given its association with severe infections and the challenges posed by antibiotic resistance often seen in Acinetobacter species.
