Answer

Historically, group A beta-hemolytic Streptococcus (GABS) has been identified as a major cause of this infection. This monomicrobial infection is usually associated with an underlying cause, such as diabetes, [25] atherosclerotic vascular disease, or venous insufficiency with edema. GABS usually affects the extremities; approximately two thirds of the GABS infections are located in the lower extremities. [26]
