    Abstract:
    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). CONCLUSION: PABA could inhibit the adherence of Actinomyces viscosus by way of changing its cell-surface hydrophobicity.
