Acinetobacter baumannii strain NCTC7364

Acinetobacter baumannii strain NCTC7364 is a Gram-negative bacterium belonging to the genus Acinetobacter. It is characterized by a rod shape and lacks mobility, as it does not possess flagella. This organism is classified as a heterotrophic chemoheterotroph, utilizing organic compounds for energy. Acinetobacter baumannii is an aerobe, requiring oxygen for its metabolic processes, and thrives optimally at a temperature of 37°C, indicative of its mesophilic nature. The strain is free-living and can inhabit multiple environments, including those associated with human activity. It is known to harbor a single replicon and is surrounded by two membranes, consistent with its classification as a Gram-negative bacterium. Clinically, Acinetobacter baumannii NCTC7364 is significant due to its pathogenic potential in humans and various animal hosts, including Gallus gallus (chickens) and Bos taurus (cattle). It is implicated in several severe health complications, including bacteremia, necrotizing fasciitis, bloodstream infections, urinary tract infections, hospital-acquired pneumonia, and respiratory tract infections. The bacterium is notorious for its role in nosocomial (hospital-acquired) and healthcare-associated infections, complicating treatment due to its antibiotic resistance profiles. The presence of Acinetobacter baumannii in diverse environments, coupled with its ability to cause severe infections, highlights its ecological adaptability and the need for vigilant infection control measures in healthcare settings to mitigate its impact on public health.
