Cellulitis is an acute bacterial infection of the skin and underlying subcutaneous tissue, mostly caused by Group A Streptococci (Mortimer, 2000; Cox, 2009) and Staphylococcus aureus (Hadzovic et al, 2012) (Figure 1). It can occur anywhere on the body, but most commonly affects the lower limb in 75–90% of cases (Tsao and Johnson, 1997).
