Lane 1: molecular size markers Phi X 174/HaeIII; Lane 2: Biomphalaria glabrata; Lane 3: Biomphalaria tenagophila; Lane 4: Biomphalaria straminea; Lane 5: Biomphalaria prona; Lane 6: adult worm of Schistosoma mansoni; Lane 7: B. glabrata infected by S. mansoni; Lane 8: B. tenagophila infected by S. mansoni; Lane 9: B. straminea infected by S. mansoni; Lane 10: DNA of B. prona with DNA of S. mansoni; Lane 11: adult worm of S. mansoni. The numbers on the left of the gel represent the value in base pairs (bp).
