Staphylococcus aureus strain YNSA94

Staphylococcus aureus strain YNSA94 is a Gram-positive, cocci-shaped bacterium that typically forms clusters or singles. This strain is classified as facultatively anaerobic, indicating its ability to thrive in both the presence and absence of oxygen. It is non-motile and does possess flagella, although its movement is not characteristic of motile organisms. Optimally, S. aureus YNSA94 grows at a temperature of 3°C, fitting within the mesophilic temperature range. This strain is associated with various host organisms, including Homo sapiens (humans), Gallus gallus (chickens), Bos taurus (cows), and several others spanning mammals and birds. The health effects linked to S. aureus YNSA94 are significant, ranging from infections such as vertebral osteomyelitis, pneumonia, and abscesses, to severe conditions like bacteremia, endocarditis, and septic arthritis. The bacterium is also implicated in food safety incidents and various opportunistic infections, highlighting its pathogenic potential in both humans and animals. Understanding the biotic relationship of S. aureus YNSA94 as free-living yet capable of causing a wide array of infections reinforces its ecological impact. Its ability to infect multiple host species suggests a versatile adaptability, which may contribute to its persistence in diverse environments and its role in both clinical and agricultural contexts. Consequently, recognizing the pathogenicity of S. aureus YNSA94 is critical for managing infections and ensuring food safety across species.
