The present invention relates to certain microorganisms or mixtures thereof for use in the treatment and/or prevention of inflammation in the oral cavity, preferably for the treatment and/or prevention of gingivitis and/or peridontitis.

In particular, the present invention relates to microorganisms or mixtures thereof for use as probiotic agents for forming co-aggregates with microorganisms associated with gingivitis and/or peridontitis.

Furthermore, the present invention provides oral pharmaceutical compositions, oral care products or products for nutrition or pleasure comprising one or more of the probiotic microorganisms as active agents as well as a method of production thereof.

The present invention relates to a method for a chewing-gum based mitigation of virus-related disease spread and pre-immunity activation based on disruption of syntrophic methanogenic processes in the oral-, shared oronasal and orotracheal microbiome. The invention provides a chewing gum composition comprising a methylotrophic yeast, preferably Komagataella phaffii; a plant lectin, preferably phytohaemagglutinin; and/or iron particles, preferably zero-valent iron particles.

Chewing gums and chewing gum bases which are cud-forming and chewable at mouth temperature contains a multi-block copolymer having at least two repeating sequences of at least two different polymeric blocks having at least three monomer units each. The multi-block copolymer optionally includes linking units and may be formulated to have non-covalent crosslinking between the copolymer chains. The multi-block copolymer is optionally plasticized with a compatible di-block copolymer to function as an elastomer system in the gum base. Characteristics of the multi-block copolymers can be selected to produce gum bases and chewing gums having desired properties. In some cases, chewed cuds formed from the gum bases may exhibit improved removability from environmental surfaces to which they may become undesirably attached.

The invention provides improvements of lantibiotics useful for reducing the numbers of microbes or the reproduction of microbes in or on subjects or objects. One embodiment of the invention provides variants of antibiotics wherein the amino acid at position (1) is changed to Ile or Gly, the amino acid at position (4) is changed to an Ala, the amino acid at position (4) is removed, the amino acid at position (5) is changed to an Ala, or wherein, as in the case of MU1140, the amino acid at position (13) is Arg, the Arg at position (13) is substituted with Asp, or combinations of two or more these changes or a pharmaceutically acceptable salt thereof.

The present disclosure discloses a strain of Lactobacillus fermentum capable of preventing and/or treating periodontitis and an application thereof, belonging to the field of microbiology technology. The present disclosure has screened to obtain a strain of L. fermentum CCFM1139. The L. fermentum CCFM1139 can alleviate periodontitis by inhibiting formation of mixed bacterial biofilms of Porphyromonas gingivalis, Prevotella intermedia and Fusobacterium nucleatum, thereby reducing the amount of biofilm by 52.45%, and can reduce the content of TNF- from 131.37 pg/mL to 83.31 pg/mL and IL-8 from 147.70 pg/mL to 121.12 pg/mL in a periodontitis cell model, reduce colonization of the P. gingivalis and the F. nucleatum in the oral cavity by 1-2 orders of magnitude, and reduce the amount of the alveolar bone resorption from 1838.0 m to 805.7 m.
