Acinetobacter baumannii strain M8

Acinetobacter baumannii strain M8 is a Gram-negative, rod-shaped bacterium classified as a chemoheterotroph. It thrives in multiple habitats and exhibits a free-living lifestyle, primarily functioning as an aerobe. This strain has a mesophilic temperature range, with an optimal growth temperature of 37°C, which aligns with human body temperature, indicating its potential pathogenicity in human hosts. Acinetobacter baumannii is notable for its lack of mobility, despite the presence of flagella. It possesses a singular replicon and is characterized by a double membrane structure. This bacterium is associated with a variety of severe health effects in humans, including bacteremia, necrotizing fasciitis, and multiple forms of infections such as bloodstream infections, urinary tract infections, and hospital-acquired pneumonia. It is known to cause both healthcare-associated and community-acquired infections, making it a significant concern in medical settings. The strain M8 has been documented to infect various hosts, including Homo sapiens, Gallus gallus (chickens), and Bos taurus (cattle), indicating its versatility in infecting both humans and other animals. The presence of this bacterium in diverse ecological niches and its ability to cause a range of serious infections underline its importance in microbiological research and public health. Understanding the ecological dynamics of Acinetobacter baumannii can aid in developing strategies to manage its spread and mitigate its impact on human health.
