Abstract
Objective: To establish a quick and simple molecular approach for the screening of H. pylori and H. pylori carrying A2142G, A2143G mutations. Subject and method: Fifteen HP colonied endoscopsic biopsies were collected as studying subject. Modified polymerase chain reaction (PCR) was applied with intergration of amplification refractory mutation system (ARMS) technology. Result was confirmed by direct sequencing. Result: PCR-ARMS was successful established. The result showed that it’s sensitivity and specificity was similar to direct sequencing, but low price, less required equipment, technician and time-comsuming. Conclusion: A bi-directional allele specific PCR implemented with amplification refractory mutation system (ARMS) have been launched, which gave absolute concordance to the classical Sanger sequencing analysis.
