After ingestion of pathogenic E. coli O111:K58:B4 or apathogenic E. coli O83 or Proteus strains, adult volunteers excreted the bacteria during a relatively short time. On the other hand, a considerably longer duration of the excretion was observed in the case of the E. coli O126:K71:B16 strain. The duration of excretion depends on the individual qualities of the persons and on the number and properties of the ingested organisms. Four out of the 13 volunteers who had ingested the pathogenic coli strains complained of mild intestinal discomfort. The disappearance of ingested bacteria from the intestinal tract is probably due to the fact that the bacteria do not proliferate with sufficient intensity. The non pathogenic organisms were excreted rapidly.
