FIG 4.
CT ELISA of rabbit ileal loop fluid produced in the presence and absence of CLA. Ten-centimeter ileal loops were injected with approximately 106 CFU V. cholerae C6706, followed by a separate injection containing either the indicated percentage of CLA in 10% Kollidon or control carrier 10% Kollidon (denoted by a zero in the CLA row) in a 1-ml volume. Analyzed data are presented as the mean results ± standard deviations. Statistical significance was determined by using the χ2 and Student t tests. P values of less than 0.05 were considered statistically significant. **, P < 0.005; ***, P < 0.0005.
