Clinical presentations | No. of S. aureus strains | No. of PVL + strains n (%) | No of PVL – strains n (%) | Odds ratio* (95% CI) | P value |
---|---|---|---|---|---|
Superficial abscesesses | 38 | 33(86,8%) | 5 (13,2%) | 2.49(0.92,6.74) | 0.072 |
Skin and soft tissue infections | 119 | 93(78,2%) | 26 (21,8%) | 1.43(0.78,2.62) | 0.247 |
Bone and joint infections** | 33 | 23(69,7%) | 10 (30,3%) | 0.72(0.32,1.65) | 0.447 |
Other infections*** | 34 | 19(55,8%) | 15 (44,2%) | 0.34(0.16,0.75) | 0.007 |
*Odds ratio is the ratio of the risk of the presence of a particular type of infection if s. aureus isolate is PVL positive. CI, confidence interval. **Bone and Joint infections – osteomylitis n=26, bursitis n=7. ***Other infections – sepsis n = 10, pneumonia n=2, deep abscesses n=3, ventriculoperitoneal shunt infection n=1, polytrauma n=1, paraproctitis n=2, pyelonephritis n=2, necrotizing enterocolitis n=1, purulent conjunctivitis n=4, intrauterine infection n=1, encephalopathy n=1, pilonidal abscess n=1, lymfangioma n=1, purulent atheroma n=1, bone cyst n=1, phlebitis n=1, infected haemathoma n=1.
