In order to compare the sensitivity of RT-LAMP and RT-PCR, serial 10 fold dilutions containing 9.91 x 1010 to 9.91 x 10-2 copies of cDNA of Pestivirus A, were prepared and tested. RT-LAMP proved more sensitive and was able to detect 9.91x100 copies of cDNA compared to RT-PCR (9.91x101). Both RT-LAMP and RT-PCR were found equally specific as no cross reaction with bovine herpes virus was observed.&nbsp; Present study showed that RT-LAMP assay is highly sensitive, specific, rapid and can be used as an alternative to conventional RT-PCR, for the detection of Pestivirus A.</p> Pestivirus A, Sensitivity, Specificity, RT-LAMP, RT-PCR Pakistan Agricultural Scientists Forum https://thejaps.org.pk/AbstractView.aspx?mid=06-IBC-19-017
