Presented values of pH assay are means of triplicate determinations; ± indicates standard deviations from the mean. Mean values (± standard deviation) within the same column followed by different superscript letters differ significantly (P < 0.05). Mean values (±standard deviation) within the same line followed by different superscript numbers differ significantly (P < 0.05). Gv: G. vaginalis; Ng: N. gonorrhoeae. The measurement of the inhibition halos of the microdiffusion assay includes the diameter of the PVC cylinder (8 mm). Contact means that there was no growth of the pathogen just inside the PVC cylinder.
