[Effect of para-aminobenzonic acid on cell-surface hydrophobicity of Actinomyces viscosus].
OBJECTIVE
To study the effect of Para-aminobenzonic acid (PABA) on cell-surface hydrophobicity of Actinomyces viscosus.


METHODS
Microbial adhesion to hydrocarbons (MATH) was used to measure the cell-surface hydrophobicity of Actinomyces viscosus which grew in modified Carlsson medium with different dilution of PABA.


RESULTS
Following the increase of concentration of PABA, the value of cell-surface hydrophobicity of Actinomyces viscosus decreased, which were 0.38900 +/- 0.00026, 0.25462 +/- 0.00168, 0.16360 +/- 0.00026 respectively(P < 0.05).


CONCLUSIONS
PABA could inhibit the adherence of Actinomyces viscosus by way of changing its cell-surface hydrophobicity.
