Acinetobacter baumannii strain CIAT758

Acinetobacter baumannii strain CIAT758 is a Gram-negative, rod-shaped bacterium that thrives as a chemoheterotroph, utilizing organic compounds for energy. It is classified as an aerobe, requiring oxygen for growth, and is mesophilic with an optimal growth temperature of 37°C. This bacterium is characterized by its single-cell arrangement and the presence of flagella, which may contribute to its motility. Strain CIAT758 is notable for its free-living lifestyle and its ability to inhabit various environments. It possesses two replicons and two membranes, features that are common in certain bacteria but may also play a role in its adaptability and survival in diverse habitats. The organism is recognized for its pathogenicity in humans, where it is associated with a range of serious health effects, including bacteremia, necrotizing fasciitis, bloodstream infections, urinary tract infections, and hospital-acquired pneumonia, among others. Its capacity to cause severe infections is further compounded by its involvement in healthcare-associated infections and wound contaminations, indicating a strong link to nosocomial settings. In terms of biotic relationships, CIAT758 has been documented to infect not only humans (Homo sapiens) but also other hosts such as chickens (Gallus gallus) and cattle (Bos taurus). This broad host range may facilitate its persistence in various ecological niches, thereby enhancing its potential for transmission and pathogenicity in human populations. The strain exemplifies the challenges posed by antibiotic-resistant pathogens in healthcare environments, emphasizing the need for ongoing surveillance and research.
