| issr, an effective molecular approach for studying genetic variability among schistosoma japonicum isolates from different provinces in mainland china. | in the present study, inter-simple sequence repeats (issrs) markers were used to examine the genetic variability of schistosoma japonicum isolates from different provinces in mainland china, using s. japonicum from japan and s. mansoni from puerto rico for comparison. of the 30 primers screened, 4 produced highly reproducible issr fragments. using these primers, 107 discernible dna fragments were generated with 105 (98.13%) being polymorphic, indicating considerable genetic variation among the e ... | 2009 | 19539784 |
