Staphylococcus aureus strain 23

Staphylococcus aureus strain 23 is a Gram-positive bacterium characterized by its cocci shape and arrangement in clusters or singles. This strain exhibits a facultative anaerobic oxygen requirement and lacks mobility, as it does not possess flagella. Staphylococcus aureus strain 23 is mesophilic, thriving at an optimal temperature of 3°C, and has a single membrane and a single replicon. This strain is host-associated, with a diverse range of hosts including Homo sapiens, Gallus gallus, Bos taurus, and various other mammals and birds. It has been identified as a pathogen in both humans and animals, causing a wide array of health issues such as vertebral osteomyelitis, bacteremia, pneumonia, and skin and soft tissue infections. The strain is also implicated in more severe conditions like septic arthritis, meningitis, and nosocomial infections, highlighting its clinical significance. The ecological role of Staphylococcus aureus strain 23 is noteworthy, as it exists in a free-living biotic relationship, potentially contributing to the microbiota of its hosts. Its pathogenicity in multiple species suggests a versatile adaptation mechanism and serves as a reminder of the importance of monitoring such strains in both clinical and agricultural settings to prevent outbreaks and manage infections effectively. The presence of this strain in various hosts underscores its impact on public health and veterinary medicine, making it a significant concern in food safety and infectious disease management.
