Staphylococcus aureus strain YNSA51

Staphylococcus aureus strain YNSA51 is a Gram-positive cocci bacterium that exhibits a cluster formation, typically found in host-associated environments. This strain is classified as facultatively anaerobic, allowing it to thrive in varying oxygen conditions, and it does not possess mobility due to the absence of flagella. With a single replicon and membrane, S. aureus YNSA51 is mesophilic, with an optimal growth temperature of 3°C, suggesting it can adapt to a range of moderate temperatures. This strain has a diverse array of hosts, including Homo sapiens (humans), Gallus gallus (chickens), Bos taurus (cattle), and various other mammals and birds. Its pathogenicity is significant, being implicated in various health concerns such as vertebral osteomyelitis, bacteremia, pneumonia, abscesses, and numerous skin and soft tissue infections. Other serious conditions include endocarditis, sepsis, and opportunistic infections, indicating its potential to affect both humans and animals. The wide host range and associated health effects suggest that S. aureus YNSA51 plays a critical role in both human and veterinary medicine. Its presence in diverse environments raises concerns regarding food safety and the management of infections across species. The strain's ability to cause severe illnesses emphasizes the need for ongoing surveillance and research to understand its ecological dynamics and to mitigate its impact on health.
