Research students from the Concordia University, St. Paul Science Department has collected over 1,000 nasal swabs over the past 5 years in an attempt to characterize nasal isolates of Staphylococcus aureus from healthy individuals. S. aureus is a common commensal bacterium found on the skin, in the nares, or in the vaginal tract of approximately 30% of the population. While S. aureus is typically harmless when it is growing in those areas, it can also pose a public health risk as it can act as an opportunistic pathogen to cause a variety of infections, such as toxic shock syndrome. The current study is to characterize toxin production of the S. aureus isolates collected. S. aureus' infectious capacity and its success as a pathogen is related to its expression of virulence factors, among which is the production of toxins. For this reason, a better understanding of S. aureus toxins is needed to enable further research and development of new strategies to reduce production of toxins and consequently improve therapeutic approaches.
