Abstract

A new method for detecting and quantitating antibodies against Vibrio cholerae is described. The reaction involves the release of radiochromium from prelabeled vibrios in the presence of specific antibody and complement. The entire assay can be completed within 5 hr. The method is highly reproducible, immunologically specific, temperature- and complement-dependent, and significantly more sensitive than other methods currently used for titration of anti- Vibrio cholerae antibodies. The technique is also potentially applicable to titration of antibodies against other gram-negative bacteria.
