An improved quantitative real-time polymerase chain reaction technology for Helicobacter pylori detection in stomach tissue and its application value in clinical precision testing.

ABSTRACT: BACKGROUND:Helicobacter pylori (H. pylori) infection is a serious human health threat. The empiric H. pylori treatment paradigm guided by traditional testing technologies has led to antibiotic resistance. Here, we improved the qPCR method to provide technical support for precision H. pylori diagnosis and treatment. METHODS:Two pairs of primers and probes targeting the glmM gene were designed to detect H. pylori, and a multiplex qPCR method was established for virulence factor detection. Then, a rapid urease test (RUT), culturing and qPCR were performed on 141 specimens collected from Xinqiao Hospital of China in 2017 to evaluate the qPCR detection capability. Finally, the H. pylori infectious amount and virulence genes were detected by qPCR. RESULTS:1. The improved qPCR method which used two pairs of primers had a higher detection rate (100%) and better accuracy (p?=?0.000), compared with the qPCR using a pair of primers. It also had better consistency with the bacterial culture than with RUT (Kappa =0.440, p?
