Acinetobacter baumannii strain SCPM-O-B-8560(4554)

Acinetobacter baumannii strain SCPM-O-B-8560(4554) is a Gram-negative, rod-shaped bacterium classified as a chemoheterotroph. This strain exhibits an aerobic metabolism and is characterized by its single-cell arrangement. It possesses flagella, which while indicating potential motility, is noted to be non-motile in practice. The optimal growth temperature for this strain is 37°C, placing it within the mesophilic temperature range. Strain SCPM-O-B-8560(4554) is free-living and has been identified in multiple habitats, suggesting its versatility in environmental adaptability. It contains a single replicon and is distinguished by its double membrane structure, typical of Gram-negative bacteria. This strain is of significant concern in human health, as it is associated with various severe infections, including bacteremia, necrotizing fasciitis, bloodstream infections, urinary tract infections, and hospital-acquired pneumonia. It is known to cause both healthcare-associated infections and community-acquired infections, particularly among vulnerable populations. Its pathogenicity is linked to its ability to thrive in clinical settings, where it can contaminate wounds and cause respiratory tract infections, particularly in individuals with traumatic injuries. The ecological insight drawn from the traits of A. baumannii strain SCPM-O-B-8560(4554) highlights its role as an opportunistic pathogen in healthcare environments. Its free-living nature combined with a diverse range of health effects underscores the need for ongoing surveillance and control measures to mitigate the risks associated with its infections in human hosts, including Homo sapiens and domesticated animals like Gallus gallus and Bos taurus.
