PCR amplification of 28S D1 (A) and 18S rDNA (B) gene fragments from DNA extracted from 15 human common bile stones. The samples were separated via electrophoresis on 2% agarose gel. Lane M: size marker (0.4 µg, 1 kbp plus DNA ladder, Invitrogen). In panel A; Lane 1, 7 and 8: 28S D1 rDNA gene for C. sinensis positive patients (1: a 90-year-old female, 7: a 69-year-old male, 8: a 51-year-old male), In panel B; Lane 7: 18S rDNA gene for A. lumbricoides positive patients (7: a 69-year-old male).
