FIG. 3.
Fluorescence and growth of gfpm2+-expressing M. terrae in a quantitative carrier test in the presence of a high organic load. Kinetics were recorded for disinfectants at a concentration of 1.5% (vol/vol). (A and B) Fluorescence (A) is expressed as relative fluorescence units (RFU) and growth is expressed in CFU for M. terrae after exposure to the peracetic acid based-disinfectant (PAA). (C and D) Fluorescence (C) is expressed in relative fluorescence units (RFU) and growth of M. terrae is expressed in CFU (D) after exposure to the cation-based disinfectant (Gigasept Instru AF). Data are the means ± standard deviations for three RFU determinations and one CFU determination for each disinfectant.
