Egg yolk immunoglobulin interactions with Porphyromonas gingivalis to impact periodontal inflammation and halitosis.


ABSTRACT: Porphyromonas gingivalis is a pathogenic Gram-negative anaerobic bacterium that colonizes the subgingival region of gums. These bacteria can invade periodontal tissues, form plaques, and produce volatile sulfur compounds (VSC) and volatile organic compounds (VOC). Egg yolk immunoglobulin (IgY) that was specifically produced in egg yolks after chickens were challenged with P. gingivalis could control and prevent oral diseases caused by P. gingivalis. The releases of P. gingivalis offensive metabolic odors in vitro and in vivo were determined using a Halimeter and GCMS. With IgY bacterial growth was inhibited, and the relative amounts of VOC and VSC were decreased. The scores for the oral health index and the levels of IL-6 and TNF-? are also decreased. All treatment groups showed significant anti-inflammatory effects, which strongly suggests that specifically IgY against P. gingivalis may be an effective treatment for the prevention and protection of periodontal inflammation and halitosis.
