Acinetobacter baumannii strain SH37

Acinetobacter baumannii strain SH37 is a Gram-negative, rod-shaped bacterium characterized by its heterotrophic and chemoheterotrophic metabolism, allowing it to utilize organic compounds for energy. This strain is classified as an aerobe, indicating that it requires oxygen for growth. Acinetobacter baumannii SH37 typically exists as single cells, lacks mobility, and possesses flagella, which may play a role in its environmental interactions despite its immobility. The optimal growth temperature for this strain is around 37°C, fitting within the mesophilic temperature range. It has a simple genomic structure with one replicon and is enclosed by two membranes, characteristic of Gram-negative bacteria. Acinetobacter baumannii SH37 is free-living, meaning it does not rely on a host for survival, although it can infect various hosts, including humans (Homo sapiens), chickens (Gallus gallus), and cattle (Bos taurus). Clinically, this strain is notably pathogenic to humans, associated with a range of serious health effects including bacteremia, necrotizing fasciitis, and various healthcare-associated infections such as hospital-acquired pneumonia and urinary tract infections. The ability of A. baumannii to thrive in diverse environments and its association with severe infections highlight its role as a significant opportunistic pathogen in both community and healthcare settings. This bacterium's resilience and adaptability may contribute to its prevalence in nosocomial infections, posing ongoing challenges in infection control within healthcare facilities.
