Comparison of genotyping Helicobacter pylori directly from biopsy specimens and genotyping from bacterial cultures.

Chang-Young Park1, Minjung Kwak, Oscar Gutierrez, David Y Graham, Yoshio Yamaoka.   

Abstract

PCR for vacA and cagA genotypes of Helicobacter pylori using DNA isolated from infected gastric biopsy specimens was approximately equal to genotyping using bacterial DNA from cultures. Inconsistent results were associated with low H. pylori density in biopsies. A higher proportion of mixed infection was found when biopsies were used.
