title: [Effect of para-aminobenzonic acid (PABA) on cell-surface hydrophobicity of Streptococcus mutans].
abstract: OBJECTIVE
  To study the effect of Para-aminobenzonic acid on cell-surface hydrophobicity of Streptococcus mutans.
  
  
  METHODS
  Microbial adhesion to hydrocarbons (MATH) was used to measure the cell-surface hydrophobicity of Streptococcus mutans which grew in modified Carlsson medium with different dilutions of PABA.
  
  
  RESULTS
  The cell-surface hydrophobicity of Streptococcus mutans increased when Carlsson medium contained low dilution of PABA. But following the increase of PABA, the cell-surface hydrophobicity decreased.
  
  
  CONCLUSIONS
  Para-aminobenzonic acid could inhibit the adherence of Streptococcus mutans through changing its cell-surface hydrophobicity.
