AIM To determine the rate of furazolidone resistance of Helicobacter pylori (H. pylori) isolated from gastric biopsy specimens and to explore the relationship between genetic mutations in porD and oorD genes of H. pylori and its resistance to the antibiotic. METHODS Gastric biopsy was performed in 83 adult patients aged 31-77 years with gastric(More)
OBJECTIVE To detect the influence of the CagT protein on interleukin-8 secretion and proliferation in SGC-7901 cells. METHODS Helicobacter pylori cagT gene was amplified by PCR with the genomic DNA of H. pylori NCTC 11637 as template, then it was inserted into an expression vector pQE30. The recombinant plasmid was transformed into E. coli M15.(More)
