Example of PCR amplifying S. mansoni specific 16S rDNA sequence on gDNA extracted from: Lanes 1, 2: S. mansoni adult worms (as positive controls); Lane 3: field-captured B. straminea with a black-coloured shell; Lane 4: field captured B. straminea with a red-coloured shell; Lane 5: laboratory cultured B. straminea with a black-coloured shell; Lane 6: laboratory cultured B. straminea with a red-coloured shell; Lane 7: negative control. All 87 tested individuals were found to be negative for S. mansoni infection
