| Outline of Final Research Achievements |
We investigated the relationship between levels of plasma antibodies against 4 bacterial species of periodontal pathogens and a level of plasma antibody against HIV in 242 blood samples randomly collected from the general population older than 20 years in Mbita region of Kenya. As a result, we found that groups with higher levels of anti-HIV showed lower levels of anti-periodontal pathogens. This tendency was observed in the relationship between anti-HIV and anti-other pathogens. These results indicate that general suppression of antibody production by HIV infection affects production of anti-periodontal pathogens antibodies.
