  • a Control values in the absence of inhibitors were as follows: LL-20/p13, 1.2 × 107 ± 0.2 × 107; ATCC 48868, 0.61 × 107± 0.01 × 107; NCYC 1364, 0.11 × 107 ± 0.03 × 107.

  • b Cell densities are expressed as percentages of the value obtained with no inhibitor.

  • c CI, complete inhibition.

  • d Cells were incubated in proteinase K at 30°C for 30 min.
