Agarose gel visualizing the products of nested trials with products of direct PCR for samples LD8 – L. confusus, LD9 – L. desertorum; LD12 – L. fabarum; and LD13 – L. alpinus. The products of LD8 and LD9 from PCR with LCO1490/Lys1Rd were submitted to secondary reactions combining two primer pairs, viz., 1. LCO1490/Lys1Rn; and 2. Lys1Fn/Lys1Rd. Amplicons of LD8, LD9 and LD12 obtained with Aph2Fd/Lys2Rd were submitted to secondary nested trials with primer pairs Aph2Fd/Lys2Rn and Lys2Fn/Lys2Rd. Products from direct PCR with Lys3Fd/HCO2198 were used as the template for nested reactions with Lys3Fd/Aph3Rn and Lys3Fn/HCO2198.
