Test organisms had been resuspended in 10 per cent organic soil to yield a final concentration of approximately five.0 105 CFUs/ml. Efficacy was evaluated at manufacturers’ advisable soak occasions: PHMB/PQ-1 for four hours and alexidine/PQ-1, PQ-1/MAPD-1, PQ-1/ MAPD-2, PQ-1/MAPD-3 for six hours.23BIOCIDAL EFFICACY TESTING OF MULTIPURPOSE Solutions Inside a LENS CASE1.704.93 four.93 four.93 -0.1 4.934.90|| four.90|| 3.83 -0.87 four.07Mean log reductions in bold indicate statistical significance. p 0.05 versus PQ-1/MAPD-1, -2, -3. p 0.01 versus PQ-1/MAPD-1, -2, -3. p 0.001 versus PQ-1/MAPD-1, -2, -3. p 0.05 versus PQ-1/MAPD-2. || p 0.05 versus.
