Necrotizing fasciitis Streptococcus infection

Necrotizing fasciitis caused by *Streptococcus* infection—primarily classified as monomicrobial or Type II necrotizing fasciitis—is a severe, rapidly progressive bacterial infection targeting the subcutaneous adipose tissue and fascial planes It most frequently arises from invasive *Streptococcus pyogenes* (Group A *Streptococcus*), affecting the extremities, perineum, or trunk in both previously healthy individuals and patients with predisposing comorbidities Pathophysiologically, bacterial exo...

Pathophysiologically, bacterial exotoxins and superantigens drive rapid tissue destruction, vascular thrombosis, and widespread tissue necrosis, often complicated by streptococcal toxic shock syndrome
