Comparison of positive virulence genes of of MRSA strains isolated from bloodstream infections in sickle cell disease (SCD) patients, Riyadh, Saudi Arabia (N = 34) Between Male (N = 24) and Female (N = 10) patients
| Gene* | Positive gene% | Carriage (N) Male | Carriage (N) Female | Total | **P-value |
|---|---|---|---|---|---|
| sea | 38.2 | 8 | 5 | 13 | 0.434 |
| Tst | 5.9 | 2 | 0 | 2 | 1 |

*sea = Staphylococcal enterotoxin A, Tst = Toxic shock syndrome toxin-1, pvl = Panton-Valentine leukocidin, hlg = Gamma-hemolysin gene, seb = Staphylococcal enterotoxin B, and sec = Staphylococcal enterotoxin C. ** If the P-value is more than 0.05, this means that the observed difference in resistance between males and females to this antibiotic is not statistically significant. The statistical analysis was performed using Chi-squared test in SPSS (IBM SPSS Statistics 29, USA)
