ABSTRACT
Objective To identify genomic DNA of Schistosoma ?. Methods Amplification of genomic DNA by the random-amplified polymorphic DNA polymerase chain reaction (RAPD-PCR) with 10-base pair was used. The 50 worms were collected from rabbits infected with cercariae of S.? and Schistosoma japonicum(S.j.) respectively. RAPD-PCR were performed on PCR-2400 according to the manufature's instruction. And 29 primers were adopted from Operon Company. The samples were run on 1.4% sepharose. Results RAPD fragments produced were various in quantity(4-12 bands)and size(0.5-5.2Kb) in S.? and S.j. , most of about 224 bands produced with 27 different primers were common, but 6 differential bands produced with 2 primers (J 01 CCCGGCATAA and L 12 GGGCGGTACT) of the 29 primers were found, 4 and 2 of the 6 differential bands seen in the S.? and S.j. respectively. Conclusion These specific fragments found in S.? and S.j. may be used as molecular markers for the identification of S.? and S.j.
