Acinetobacter baumannii strain Aci00864

Acinetobacter baumannii strain Aci00864 is a Gram-negative, rod-shaped bacterium that thrives in various habitats and exhibits a free-living lifestyle. As a chemoheterotroph, it derives energy by consuming organic compounds, and it is classified as an aerobe, requiring oxygen for growth. This strain is non-motile and has a flagellar presence, which may play a role in its environmental adaptability. Aci00864 is mesophilic, with an optimal growth temperature of 37°C, which aligns with the typical human body temperature, suggesting a close association with human hosts. This strain has been implicated in several health concerns, including bacteremia, necrotizing fasciitis, bloodstream infections, urinary tract infections, and hospital-acquired pneumonia. Its ability to cause severe infections, such as those following traumatic injuries or as part of healthcare-associated infections, highlights its pathogenic potential. The bacterium has a single replicon and is characterized by a double membrane structure, which is typical for Gram-negative organisms. Its relationships with various hosts, including humans (Homo sapiens), chickens (Gallus gallus), and cattle (Bos taurus), indicate its ecological versatility and ability to adapt to different biological environments. In summary, Acinetobacter baumannii strain Aci00864 exemplifies a significant opportunistic pathogen within healthcare settings, capable of causing a range of serious infections, particularly in immunocompromised individuals. Its environmental resilience and association with multiple hosts underscore the need for ongoing surveillance and research to manage its impact on public health.
