Staphylococcus aureus strain YNSA49

Staphylococcus aureus strain YNSA49 is a Gram-positive, cocci-shaped bacterium that typically forms clusters or singles. This strain is facultatively anaerobic, indicating its ability to thrive in both aerobic and anaerobic environments. It is non-motile and possesses flagella, though the exact role of these structures in its biology is not specified. YNSA49 has a mesophilic temperature range, with an optimal growth temperature of 3°C. It contains one replicon and one membrane. This strain is found in a variety of hosts, including Homo sapiens, Gallus gallus, Bos taurus, and several others, suggesting its capacity to adapt to diverse biological environments. S. aureus YNSA49 is associated with numerous health effects in both humans and animals. It is known to cause a wide range of infections, including vertebral osteomyelitis, bacteremia, pneumonia, and skin infections, as well as more severe conditions like endocarditis and septicemia. The strain is implicated in both opportunistic and nosocomial infections, highlighting its pathogenic potential. Ecologically, the presence of this strain in various hosts indicates a complex biotic relationship, as it can thrive in free-living conditions while also establishing pathogenic relationships. The diversity of infections it causes suggests that S. aureus YNSA49 plays a significant role in both health and disease dynamics across species, particularly in environments where hosts interact closely, such as livestock and human populations. This emphasizes the importance of monitoring and managing S. aureus infections to mitigate health risks associated with this versatile pathogen.
