Staphylococcus aureus strain YNSA21

Staphylococcus aureus strain YNSA21 is a gram-positive coccus characterized by its arrangement in clusters and singles. This strain is facultatively anaerobic, indicating its ability to thrive in both the presence and absence of oxygen. It is non-motile, lacking flagella, and has a single membrane with one replicon. The optimal growth temperature for YNSA21 is 3°C, placing it within the mesophilic temperature range. This strain is known to have a wide host range, affecting various species, including humans (Homo sapiens), domestic animals such as chickens (Gallus gallus), cattle (Bos taurus), and dogs (Canis lupus familiaris), as well as other mammals and birds. Its pathogenicity is significant, as it can cause a variety of infections in these hosts, including vertebral osteomyelitis, bacteremia, pneumonia, abscesses, and skin infections, among others. The extensive list of health effects associated with S. aureus strain YNSA21 underscores its role as a serious pathogen in both human and animal health. It is implicated in numerous conditions, ranging from mild skin infections to severe systemic diseases such as sepsis and endocarditis. Additionally, its ability to cause infections across various hosts highlights its ecological adaptability and potential for zoonotic transmission. In summary, S. aureus strain YNSA21 exemplifies the versatility and pathogenic potential of Staphylococcus aureus, making it a prominent concern in both clinical and veterinary medicine. Its presence in diverse hosts suggests the importance of monitoring and controlling infections to prevent outbreaks and safeguard health.
