| Outline of Final Research Achievements |
Diagnosis for H. pylori requires time and expenses. In this study, we focused on "the existence of H. pylori in saliva" as previously reported and by using saliva, attempted to develop a rapid and inexpensive H. pylori infection diagnosis and an antibiotic susceptibility test. First, using a standard solution in which H. pylori was reliably present, PCR was carried out with a template (primer) of H. pylori DNA as previously reported and an H. pylori-specific peak was recognized. However, in patients saliva (infected / non-infected), no specific peak was observed. We tried modification of PCR condition, use of other primers, concentration of specimen, change to primer for toxin DNA of H. pylori, but H. pylori in saliva was not detectable.
