  • a Results were determined on the 10th day of incubation. Data for four experiments are shown. The widths of the halos and inhibition zones were measured manually. Due to the identical conditions and because of the resolution limit of manual measurement, no detectable deviations were observed.

  • b Faintly visible.

  • c Strains 4a.3.11, 7.3.10, 9.4.60, and 11.3.38 give similar but somewhat weaker reactions.
