Abstract

The invention discloses an IgY antibody preparation having mixed specificity for resistance to streptococcus mutans and streptococcus sobrinus. The IgY antibody preparation is prepared by mixing 10-70 parts by weight of streptococcus mutans bacteria and bacteria pieces and 30-90 parts by weight of streptococcus sobrinus bacteria and bacteria pieces into an antigen via laying hens. The invention also discloses a preparation method of the IgY antibody preparation having the mixed specificity for resistance to the streptococcus mutans and the streptococcus sobrinus, and a toothpaste which contains the IgY antibody preparation having the mixed specificity for resistance to the streptococcus mutans and the streptococcus sobrinus and the IgY antibody preparation having the mixed specificity for resistance to the anti-porphyromonas gingivalis and the fusobacterium nucleatum and is used for preventing saprodontia, gingivitis and halitosis thereof. The toothpaste used for preventing saprodontia, gingivitis, periodontitis and halitosis halitosis thereof has obvious effects for preventing saprodontia, gingivitis, periodontitis and halitosis bacteria thereof.

Description

technical field [0001] The present invention relates to the technical field of oral products, in particular to a preparation containing mixed specific IgY antibodies against Streptococcus mutans and Streptococcus distantis and a preparation method thereof, and a preparation containing mixed specific IgY antibodies against Streptococcus mutans and Streptococcus distantis, Toothpaste for prevention of dental caries and gingivitis and bad breath with mixed specific IgY antibody preparation of Fusobacterium nucleatum and Porphyromonas gingivalis. Background technique [0002] In my country, the dental caries rate of children aged 3-6 years is 25.49%-92.72%, and that of adults is 40.37%. Among them, Streptococcus mutans and Streptococcus distalis are the main cariogenic bacteria. The occurrence of bacterial infectious diseases firstly settles in specific organs in the body through the specific binding of adhesins bound to the surface of bacteria to their corresponding receptors ...
