characterisation of fasciola species from mainland china by its-2 ribosomal dna sequence.isolates of fasciola (platyhelminthes: trematoda: digenea) from different host species and geographical locations in mainland china were characterised genetically. the second internal transcribed spacer (its-2) of nuclear ribosomal dna (rdna) was amplified from individual trematodes by polymerase chain reaction (pcr), and the representative amplicons were cloned and sequenced. the length of the its-2 sequences was 361-362bp for all chinese fasciola specimens sequenced. while there was no variati ...200415019145
