NAD-glycohydrolase production and speA and speC distribution in Group A streptococcus (GAS) isolates do not correlate with severe GAS diseases in the Australian population.
Streptococcus pyogenes isolates from a tropical region and a subtropical region of Australia with high and low incidences of severe streptococcal diseases, respectively, were analyzed for speA, speB, and speC gene distributions and NAD-glycohydrolase expression. No direct correlation of these characteristics with a propensity to cause invasive diseases was observed.
