Resumo(s)

A PCR assay for the detection and characterization of foot-and-mouth disease virus was developed. The procedure allows RT-PCR amplification following direct adsorption of viral suspensions to microtiter plates, avoiding previous steps of phenol-extraction or heating. Using this procedure, FMDV-specific (based on 3D gene sequences), as well as serotype-specific (based on VP1 gene sequences) amplification were achieved for viral samples of serotypes A, O and C, either from cell culture supernatants or from lesions of infected animals. The assay allowed detection of around 15 PFU, being 500-fold more sensitive than a conventional indirect ELISA. This new method constitutes a simple, rapid and efficient alternative for the diagnosis and characterization of FMDV by PCR.
