SENSITIVITY OF RT-PCR METHOD IN SAMPLES SHOWN TO BE POSITIVE FOR ZIKA VIRUS BY RT-QPCR IN VECTOR COMPETENCE STUDIES

Abstract
Tissue samples from mosquitoes artificially infected with Zika virus and shown to be positive by RT-qPCR were reexamined by RT-PCR. Using these samples we compared the two methods employed in virus RNA detection for vector competence studies. Results demonstrated that, albeit useful, RT-PCR gave false negatives with low viral loads (< 106 RNA copies/ml).
