A rapid enzyme-linked immunosorbent assay for the detection of foot-and-mouth disease virus in epithelial tissues.
A rapid double sandwich enzyme-linked immunosorbent assay (ELISA) has been used for the identification and type differentiation of foot-and-mouth disease (FMD) viruses in epithelial tissue samples submitted for diagnosis from the field. No difficulty was experienced in the direct typing of freshly harvested epithelium from recently ruptured vesicles by the complement fixation (CF) test or ELISA. The ELISA was more sensitive and specific, but proved no more efficient than the traditional CF test in the direct typing of samples of poorer quality from many countries overseas where communications are often difficult. However, when both tests were used concurrently, FMD virus typings were confirmed in 27 more samples. Some possible reasons for the failure of ELISA to detect virus in certain cases are discussed.
