1. This experiment was made to determine whether the Chinesesoy bean sauce plays any part in the dissemination of diseasescaused by organisms of the typhoid and dysentery group.
2.Thirty samples of sauces were examined; 35% of these samplesshowed evidence of contamination either with E. coli, E. typhosa,S. dysenteriae, or Salmonella bacilli.
3. The hypertonicityand acidity of the samples have no significantgermicidal effecton these organisms, and E. typhosa inoculatedinto the saucecan survive for many days.
4. The fact that the soy bean sauceis frequently consumed rawand often contaminated with the typhoid-dysenterygroup of organismssuggests the possibility that they play apart in the disseminationof intestional infections in thiscountry.
