Serum resistance phenotypes were determined using the Bioscreen growth method. R, resistant (>80% growth in serum); S, sensitive (<20% growth in serum); and I, intermediate (20–80% growth in serum) at 12 h. RAPD types are strain types as determined previously by RAPD PCR and exopolysaccharide (EPS) phenotypes were previously determined by growth on yeast extract mannitol media (Mahenthiralingam et al., 1996; Zlosnik et al., 2008). Experiments were performed in triplicate on three separate days. X = RAPD type not assigned but does not match a major existing RAPD type.
