Answer

Uman et al recommended percutaneous needle aspiration followed by prompt Gram staining and culture for a rapid bacteriologic diagnosis in soft-tissue infections. [75] A needle aspirate should be taken on the advancing edge of the infection, where group A beta-hemolytic Streptococcus (GABS) is plentiful. [76]
