Abstract

Serum samples were obtained from 92 informed, community volunteers before and 10, 21, and 28 days after they ingested 10(3) to 10(6)Vibrio cholerae of Inaba or Ogawa serotype and classical or El Tor biotype as part of a cholera vaccine development program. Pre- and postchallenge sera were examined for neutralizing antibody to cholera toxin by the rabbit skin permeability factor and adrenal cell techniques.

The results obtained in these cholera volunteers were compared with a negative control population comprising 30 people who ingested enteropathogenic Es..
