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