Figure 3. Agarose gel stained with ethidium bromide showing species-specific banding profiles obtained from three of the Bulinus snails through digestion of PCR products of their entire ITS region including the 5.8S rRNA gene. Lanes: 1: Quick-Load 100 bp DNA Ladder; 2 and 3: B. truncatus; 4: B. globosus; 5: negative control. PCR: Polymerase chain reaction; ITS: internal transcribed spacer; rRNA: ribosomal RNA.
