Abstract

In order to improve simultaneous detection and identification of HELICOBACTER genus in general and HELICOBACTER pylori specifically and reduce the number of amplifications needed, we established a MULTIPLEX PCR. In this study, two pairs of primers: Hcom1 and Hcom2 specific for HELICOBACTER genus, Hicd1 and Hicd2 specific for HELICOBACTER pylori species were used. To determine the sensitivity of our MULTIPLEX PCR, the lower limits of DNA detection from pure culture were established using phenol-chloroform method. To evaluate the specificity of our protocol, we tested DNA extracted from various Gram-negative and -positive bacteria. A study was subsequently undertaken on stomach tissue samples from 18 patients to evaluate this protocol for detection of HELICOBACTER in tissue samples. In our optimized PCR, two fragments of 389- and 1200-bp were produced using Hcom1-Hcom2 and Hicd1-Hicd2 primers, respectively. Amplification of HELICOBACTER pylori genomic DNA was achieved at concentration as low as 0.03 pg equivalent to 150 bacteria. No DNA amplification of other Gram- positive and -negative bacteria was seen. Twelve specimens, positive in culture and rapid urease test for HELICOBACTER pylori were positive for DNA of this organism using this MULTIPLEX PCR. Our results demonstrate that this protocol represents a specific and sensitive assay for simultaneous detection of HELICOBACTER genus members, in general, and HELICOBACTER pylori species, specifically, in clinical samples yielding no false-positive.
