Most often, the etiologic organisms associated with perineal cellulitis and episiotomy site infections are Staphylococcus or Streptococcus species and gram-negative organisms, as in endometritis.

Vaginal secretions contain as many as 10 billion organisms per gram of fluid. Yet, infections develop in only 1% of patients who had vaginal tears or who underwent episiotomies.

Those who underwent cesarean delivery have a higher readmission rate for wound infection and complications than those who delivered vaginally. [7]
