title: Age and prevalence of Porphyromonas gingivalis in children.
abstract: The acquisition of Porphyromonas gingivalis was examined in a cross-sectional study of 198 subjects from 0 to 18 years of age using a PCR-based assay. P. gingivalis was detected in the oral cavities of 37% of subjects and at similar frequencies among subjects of all ages. These data indicate that P. gingivalis may be acquired in the first days of life.
