(A) emm distribution of strains isolated in Thunder Bay from severe skin and soft tissue infections that did not meet the criteria for iGAS disease during 2011 to 2013. The emm type distribution closely resembles the overall distribution of emm types associated with iGAS disease in Thunder Bay during the period. (B) emm type distribution of an extended GAS collection comprising strains causing invasive disease and severe skin and soft tissue infections that did not meet the criteria for iGAS disease during 2011 to 2013. In 2011, the 4 most frequently identified emm types in Thunder Bay were emm82 (23.1%), emm83 (20.5%), emm87 (10.3%), and emm114 (7.7%). In 2012, the most frequently identified emm types were emm87, emm82, emm101, and emm89 (25%, 22.2%, 16.7%, and 8.3%, respectively). Strains of emm4, emm1, emm101, and emm11 predominated in 2013 (18.2%, 15.9%, 13.6%, and 11.4%, respectively). When the 3 years are taken together, the most frequently isolated emm types were emm82 (16%), emm101 (10.9%), emm87 (9.2%), emm1 (7.6%), emm4 (6.7%), emm114 (5.9%), and emm83 (5%).
