Multiplex nested PCR for Brazilian Alphavirus diagnosis

Abstract excerpt

A reverse-transcriptase PCR (RT-PCR) and a multiplex nested PCR were developed for the rapid detection and identification of 14 Brazilian alphaviruses. Using Alphavirus genus-specific primers in a RT-PCR, we obtained amplified products of 434 bp. Species-specific primers were selected and simultaneously tested in a multiplex nested PCR. The nested PCR increased the test sensitivity 1000-fold and was capable of...
