FIG. 2.

Effects of AV and AMP on growth of Streptococcus pyogenes. Streptococcus pyogenes was incubated at 37°C in TSB alone (□) or with AV (25 mg/ml) (⋄) or AMP (25 μg/ml) (○). The number of bacteria were calculated from A₆₂₀ readings. The results are expressed as the mean A₆₂₀s ± standard deviations of three readings.
