Blocking assay for live P. gingivalis cells binding to statherin. The inhibition of live P. gingivalis cell-binding to statherin by IgA-enriched saliva of 8- or 48-week-old mice nasally immunized with rFimA plus DA or rFimA alone was examined. ATP amounts of live P. gingivalis cells were determined by luminescence using the Bac Titer-Glo Microbial cell viability assay. The numbers of 5 × 107 live cells are equivalent to 350 relative right unit (RLU) of the luminescence. The values shown are the mean ± SE (n = 5). *p < 0.05, when compared with mice group given rFimA alone
