Acinetobacter baumannii strain AB176

Acinetobacter baumannii strain AB176 is a Gram-negative, rod-shaped bacterium that serves as a chemoheterotroph, deriving energy from organic compounds. This organism is characterized as an aerobe, requiring oxygen for growth, and is mesophilic, with an optimal growth temperature of 37°C. Acinetobacter baumannii strain AB176 has a single replicon and is composed of two membranes, consistent with its classification within the Proteobacteria phylum. The strain is observed to exist as free-living organisms, demonstrating adaptability to multiple habitats. It does not exhibit mobility, although it possesses flagella, which are typically associated with motility in other bacterial species. This strain is of significant concern in healthcare settings, as it is associated with a variety of severe health effects, including bacteremia, bloodstream infections, urinary tract infections, and nosocomial infections such as hospital-acquired pneumonia. Additionally, it can lead to necrotizing fasciitis and respiratory tract infections, marking it as a versatile pathogen capable of causing both community-acquired and healthcare-associated infections. The pathogenicity of Acinetobacter baumannii strain AB176 primarily targets humans but has also been noted in other hosts, including Gallus gallus (chickens) and Bos taurus (cattle). This highlights the strain’s ecological versatility and underscores the importance of monitoring its presence in both clinical and environmental contexts to mitigate the risks associated with its infections.
