Fig. 5From: The substructure of three repetitive DNA regions of Schistosoma haematobium group species as a potential marker for species recognition and interbreeding detectionBanding patterns of inter-repeat PCR amplification (using DraI reverse and 73 bp direct primers) targeting total DNA extracted from Bulinus globosus (Lanes 1–15); Lane 16: from a previously tested negative snail; Lanes 17 and 18: negative control reactions without DNA. PCR was performed using biotinylated primers. Lanes that are marked by arrows represent the PCR products that were used for species identification by reverse line blot analysisBack to article page
