Periodontitis is an inflammatory disease induced by a dysbiotic oral microbiome. Probiotics of the genus Bifidobacterium may restore the symbiotic microbiome and modulate the immune response, leading to periodontitis control. We evaluated the effect of two strains of Bifidobacterium able to inhibit Porphyromonas gingivalis interaction with host cells and biofilm formation, but with distinct immunomodulatory properties, in a mice periodontitis model. Experimental periodontitis (P+) was induced in C57Bl/6 mice by a microbial consortium of human oral organisms. B. bifidum 162(2A) {[}B+ (1622)] and B. breve 110(1A) {[}B+ (1101)] were orally inoculated for 45 days. Alveolar bone loss and inflammatory response in gingival tissues were determined. The microbial consortium induced alveolar bone loss in positive control (P + B-), as demonstrated by microtomography analysis, although P. gingivalis was undetected in oral biofilms at the end of the experimental period. TNF-alpha and IL-10 serum levels, and Treg and Th17 populations in gingiva of SHAM and P + B- groups did not differ. B. bifidum 162(2A), but not B. breve 110(1A), controlled bone destruction in P+ mice. B. breve 110(1A) upregulated transcription of Il-1 beta, Tnf-alpha, Tlr2, Tlr4, and Nlrp3 in P-B+(1101), which was attenuated by the microbial consortium {[}P + B+(1101)]. All treatments downregulated transcription of Il-17, although treatment with B. breve 110(1A) did not yield such low levels of transcripts as seen for the other groups. B. breve 110(1A) increased Th17 population in gingival tissues {[}P-B+ (1101) and P + B+ (1101)] compared to SHAM and P + B-. Administration of both bifidobacteria resulted in serum IL-10 decreased levels. Our data indicated that the beneficial effect of Bifidobacterium is not a common trait of this genus, since B. breve 110(1A) induced an inflammatory profile in gingival tissues and did not prevent alveolar bone loss. However, the properties of B. bifidum 162(2A) suggest its potential to control periodontitis. (AU)
