Acinetobacter baumannii strain Ab191

Acinetobacter baumannii strain Ab191 is a Gram-negative, rod-shaped bacterium that exhibits distinct characteristics relevant to its ecological and pathogenic roles. This strain is classified as a chemoheterotroph, utilizing organic compounds as its energy source and thriving under aerobic conditions. Acinetobacter baumannii is free-living, primarily found in diverse habitats, and is notable for its lack of mobility, despite possessing flagella. The optimal growth temperature for strain Ab191 is 37°C, which aligns with its association with human hosts, including Homo sapiens, as well as Gallus gallus and Bos taurus. Its ability to cause a range of severe health effects, such as bacteremia, necrotizing fasciitis, bloodstream infections, and hospital-acquired pneumonia, underscores its pathogenicity in humans. The bacterium is implicated in various healthcare-associated infections, including urinary tract and respiratory tract infections, as well as wound contaminations resulting from traumatic injuries. Strain Ab191 is categorized as mesophilic, with a temperature range suitable for growth within typical environmental and body temperature ranges. With one replicon and two membranes, it displays a structure characteristic of many Gram-negative bacteria, contributing to its resilience in diverse environments. The ecological insight provided by the traits of Acinetobacter baumannii strain Ab191 suggests its adaptability and potential for survival in varied environments, particularly in healthcare settings where it poses significant risks for severe infections. The presence of this bacterium in both community and hospital settings highlights the importance of understanding its biology and pathogenic potential for effective infection control measures.
