Abstract

A microtiter enzyme-linked immunosorbent assay (ELISA) to measure immunoglobulin G cholera antitoxin in human serum has been developed. The ELISA employs commercially available reagents, including cholera enterotoxin and goat anti-human immunoglobulin G. It is specific, sensitive, and reproducible and requires as little as 5 microliter of serum. ELISA, moreover, permits quantitative determination of cholera antitoxin at a single serum dilution of 1:200. A total of 162 pre- and post-challenge sera from 49 volunteers who ingested Vibrio cholerae classical biotype, and 165 sera from 43 volunteers who ingested V. cholerae El Tor biotype, were tested for cholera antitoxin by ELISA and by the rabb..
