Text A
Necrotizing fasciitis (NF) is a severe, rare, potentially lethal soft tissue infection that develops in the scrotum and perineum, the abdominal wall, or the extremities. The infection progresses rapidly, and septic shock may ensue; hence, the mortality rate is high (median mortality 32.2%). NF is classified into four types, depending on microbiological findings.
Table 1 Classification of responsible pathogens according to type of infection:
| Microbiological type | Pathogens | Site of Infection | Co-morbidities |
| Type 1 (polymicrobial) | Obligate and facultative anaerobes. | Trunk and perineum | Diabetes mellitus |
| Type 2 (monomicrobial) | Beta-hemolytic streptococcus A | Limbs | |
| Type 3 | Clostridium species Gram-negative bacteria Vibrios spp. Aeromonas hydrophila. | Limbs, trunk and perineum | Trauma Seafood consumption (for Aeromonas) |
| Type 4 | Candida spp. Zygomycetes | Limbs, trunk, perineum | Immunosuppression. |
