PY - 2014 DA - 2014/05/29 TI - Distribution of superantigens in group A streptococcal isolates from Salvador, Brazil JO - BMC Infectious Diseases SP - 294 VL - 14 IS - 1 AB - Group A streptococcus (GAS) causes invasive disease, superficial disease, and can asymptomatically colonize humans. Superantigens are one virulence factor found in GAS. Previous studies found associations between the genes that encode superantigens and emm type of GAS. It is unknown if these associations are due to underlying biological factors that limit the distribution of superantigens or, alternatively, if these associations are due to the expansion of local GAS linages where these studies took place. To further address this question we screened GAS isolates collected from Salvador, Brazil for 11 known superantigen genes.
