Results are for sera from adults 3 to 5 months following culture-verified cholera. Undiluted sera were mixed with an equal volume of either LPS or DeALPS containing 200 μg of saccharide per ml and then incubated at 37°C for 1 h and overnight at 3 to 8°C. V. cholerae O1 strain 075, serotype Inaba, was the target organism.
