title: [An in vitro study on effect of Nidus vespae extract on the acid production of three strains of oral bacteria].
abstract: OBJECTIVE
  To inquire into the effect of different of Nidus Vespae extract (NVE) on growth and acid production of Streptococcus mutans, Streptococcus sanguis and Actinomyces viscosus.
  
  
  METHODS
  Streptococcus mutans ATCC 25175, Streptococcus sanguis ATCC 10556 and Actinomyces viscosus ATCC 19246 were chosen as the experimental bacteria. Four extracts of Nidus Vespae were prepared and then the effects of these Nidus Vespae extracts on the acid production were determined.
  
  
  RESULTS
  All of Nidus Vespae extracts could inhibit the growth the of the three strains, and NVE1, NVE3, NVE4 could inhibit the acid production of the three strains, NVE2 could inhibit the acid production of Actinomyces viscosus.
  
  
  CONCLUSIONS
  Four extracts of Nidus Vespae could inhibit the acid production of three bacteria strains.
