| Outline of Final Research Achievements |
We examined periodontal bacteria in saliva, plaque and placenta among 47 threaten preterm labor (TPL) and healthy pregnant subjects. Almost all periodontopathic bacteria were found in saliva, plaque, and placenta samples. P. gingivalis in saliva and F. nucleatum in placenta tissue were significantly higher in the TPL group than in the healthy pregnant group.
Bacteremia was induced in pregnant Jcl:ICR mice (8-weeks-old) by intravenous injection of Pg. ED or control (CO) mice were injected Pg or saline Every-Day during pregnancy.Birth weight was lower for pups in the ED groups compared to those in the CO group.
