Inhibition of P. gingivalis growth by anti-HmuY IgG antibodies. The P. gingivalis wild-type A7436 and ATCC 33277 strains and the hmuY deletion mutant (TO4) strain were grown in basal medium supplemented with dipyridyl. The cells were then washed with PBS, incubated without IgGs (-), with purified pre-immune (pre), or immune (im) anti-HmuY IgGs and inoculated into fresh BM supplemented with hemin (Hm).
