Routine application of enzyme-linked immunosorbent assay in comparison with complement fixation for the diagnosis of foot-and-mouth and swine vesicular diseases.

An indirect, sandwich enzyme-linked immunosorbent assay (ELISA) has been compared in parallel with the standard complement-fixation typing test (CFT) for the diagnosis of foot-and-mouth and swine vesicular diseases. The superior sensitivity, reproducibility, economical use of reagents and ease of performance of the ELISA confirm the hypothesis that it should replace the CFT as the routine test of choice.
