| Outline of Final Research Achievements |
Helicobacter pylori, a Gram-negative microaerophilic bacteria, is known to be a major pathogen related to gastric diseases. The oral cavity is considered to be the source of H. pylori infection, which is mainly acquired in early childhood. In the present study, a novel PCR system for H. pylori detection was constructed using primer sets designed from the complete genome information of 48 H. pylori strains. The bacteria were identified in 38.9% of 131 inflamed pulp specimens obtained from children using the PCR system. In addition, H. pylori strains showed adhesion to human dental fibroblast cells.
