title: Differences in clinical features and outcomes between group A and group G Streptococcus -induced cellulitis.
abstract: BACKGROUND
  Streptococci are the main causative agents of cellulitis, and group G Streptococcus (GGS) shares many important virulent factors with group A Streptococcus (GAS). The difference in the clinical features of GAS- and GGS-induced cellulitis, however, has not been thoroughly characterized.
  
  
  OBJECTIVE
  Our aim was to recognize the differences in the clinical manifestations and outcomes of lower limb cellulitis caused by GAS and GGS.
  
  
  METHODS
  We retrospectively analyzed a total of 29 patients diagnosed with GAS- or GGS-induced lower limb cellulitis during the period from January 2008 to September 2013.
  
  
  RESULTS
  While the clinical manifestations of GAS-induced cellulitis were likely to be uniform, those of GGS-induced cellulitis were variable, depending on the predisposing factors. GGS-induced cellulitis occurred more frequently in older person who had chronic underlying illness.
  
  
  CONCLUSIONS
  We identified clinical predisposing factors that can predict the clinical course and outcomes of GGS-induced cellulitis.
