In this issue of Internal and Emergency Medicine, Chang and coworkers identify some factors associated with bacteremia in patients with acute bacterial skin and skin structure infections (ABSSSIs) . The role of blood cultures in ABSSSIs remains controversial for several reasons. Patients with skin infections rarely have bacteremia: a systematic review of bacteremia episodes in patients with cellulitis and erysipelas shows that blood cultures are positive in only 7.9% and 4.6% of cases, respectively . Other reports show that the incidence of bacteremia in patients with uncomplicated cellulitis is 4.8%, and are due to Streptococcus spp and Staphylococcus aureus, as expected considering the classical microbiology of non-purulent skin infection [3, 4]. Among patients needing hospitalization, methicillin-resistant Staphylococcus aureus (MRSA) appears as a leading pathogen, and an increasing prevalence of community-acquired MRSA has been reported in the last decade [5, 6].
