Objective To search for the molecular figngerprint of ascaris lumbricoides in intrahepatic stones. Methods In 56 cases deoxyribonucleic acid (DNA) was exstracted from intrahepatic stones and surgically obtained bile duct tissues, stool and sercum examinations were performed. Based on the sequence and designed primers of ITS-2 of ascaris lumbricoides, polymerase chain reaction ( PCR) was performed. Results There were 12 positive results in 56 (21.4% ) cases of intrahepatic stones. Positive reaction appeared on the examinations of the stool on ascaris lumbricoides and the blood serum among 12 cases. Conclusions Ascaris lumbricoides DNA was found in human of intrahepatic stones, indicating that ascaris lumbricoides infection may play a role in the formation of intrahepatic stones.
