Background: One of virulence factors produced by Staphylococcus aureus is staphylokinase (SAK), which enhances their proteolytic activity leading to tissue damage and improving bacterial invasiveness. In the present study, we estimated the ability to produce SAK by S. aureus isolates from nasal carriers. We would like to verify relationship between SAK production and different S. aureus isolates. Methods: In this study, all nasal swab samples from healthy nasal carriers were collected and further processed in the Department of Biotechnology, Himachal Pradesh University. All S. aureus isolates were screened for SAK and optimization was done. Results: Out of all S. aureus isolates 20% isolates were positive for SAK production. Isolate SAK-24 shown increase in SAK production after optimization and response surface methodology (RSM). Conclusion: Production of SAK varies from strain to strains. SAK production can be increased by optimization and RSM.
