A 5-year-old boy returns from summer camp with several minor cuts and abrasions

Question

A 5-year-old boy returns from summer camp with several minor cuts and abrasions on legs. He has fever and extensive cellulitis, subcutaneous tissue and muscles are involved. Necrotic tissues were surgically reomoved and broad spectrum antibiotics were used. Which of the following microorganisms usually causes necrotizing fasciitis?

It is so severe that I started think that Staphylococcus aureus is possible. My previous answer was A-group streptococci, but I disagree with it now.

What is causing the case?

Explanation / Answer

Staphylococcal infection is more likely to cause abscesses and Streptococcal infection is more likely to cause cellulitis. It is not clear how a 5 year old did not get medical attantion till he got to this serious state. Why was culture not done? Surgical removal of necrotic tissue due to cut and bruises? doesn't tally with cellulitis. Incision and drainage is a standard proceedure for absecesses, is that what was done? Is this a hypothetical question?
