Acinetobacter baumannii strain Aci00853

Acinetobacter baumannii strain Aci00853 is a Gram-negative, rod-shaped bacterium classified as a chemoheterotrophic aerobe. This strain is notable for its ability to thrive in multiple habitats, exhibiting a free-living biotic relationship. It possesses a single replicon and is characterized by having two membranes, a typical feature of Gram-negative bacteria. Aci00853 shows no motility despite the presence of flagella, indicating a non-motile lifestyle. Its optimal growth temperature is 37°C, which places it within the mesophilic range, allowing it to thrive in human body temperatures, a factor contributing to its pathogenic potential. This strain is associated with a range of health effects, particularly in humans, where it can cause serious conditions such as bacteremia, necrotizing fasciitis, and various types of infections including bloodstream, urinary tract, and respiratory tract infections. Aci00853 is implicated in nosocomial (hospital-acquired) and community-acquired infections, making it a significant concern in healthcare settings. It has also been detected in other hosts, including Gallus gallus (chickens) and Bos taurus (cattle), indicating its versatility in infecting various species. The pathogenicity of Aci00853 underscores the importance of understanding its ecological interactions, particularly in hospital environments where it can lead to severe health complications. Its ability to survive and proliferate in diverse conditions highlights the challenges of infection control and the need for ongoing surveillance of multidrug-resistant strains.
