چکیده
Using polymerase chain reaction (PCR), we examined 16S ribosomal DNA (rDNA) of Helicobacter species in liver tissue specimens obtained from 15 patients with hepatocellular carcinoma. Sixty percent (9 of 15) of these specimens were found to be positive for Helicobacter species. Four 16S rDNA fragments from positive PCR samples were directly sequenced. By sequence comparison, all were found to be 99% identical to the 16S rRNA of Helicobacter pylori.

متن کاملHelicobacter hepaticus infection in primary hepatocellular carcinoma tissue.
INTRODUCTION Helicobacter (H.) hepaticus infection causes chronic active hepatitis and induces hepatocellular tumours in A/JCr mice, but evidence of this in humans is scarce. This study aimed to demonstrate the correlation between H. hepaticus and human primary hepatocellular carcinoma (HCC). METHODS The sera of 50 patients with primary HCC were tested for the presence of anti-H. pylori and a...
