An orally administered oral pathobiont and commensal have comparable and innocuous systemic effects in germ‐free mice

Abstract: The oral pathobiont P. gingivalis did not induce any detectable pathogenic changes or any major host responses when administered to germ-free mice. There may be indirect mechanisms for gut-mediated systemic effects by P. gingivalis.

“…Furthermore, Pg. in contrast to typically health associated oral commensals was eliminated from the feces, elicited systemic immune responses and induced pathological changes in the liver, which supports the importance of an oral-gut connection (93).…”

“…and PD is probably not the same, as Pg. alone at very low colonization levels was not sufficient to cause periodontitis in germfree mice, but disrupted the host-microbial homeostasis and caused severe PD when added to a community of commensal microbiota (93,94). Furthermore, Pg.…”

“…O emprego de camundogos C57BL/6 infectados por via oral com P. gingivalis é um modelo atualmente utilizado em vários estudos. A periodontite experimental promovida por P. gingivalis foi demonstrada por vários métodos, como o uso de ligadura infectada com P. gingivalis (110)(111)(112)(113)(114)(115), o uso de produtos de P. gingivalis como a gingipaína (116) ou LPS, e o uso de células vivas de P. gingivalis (38,(117)(118)(119)(120). Optamos por utilizar células vivas de P. gingivalis, pois os dados prévios de nosso grupo demonstraram que os probióticos inibem a adesão e invasão de P.…”

“…Além disso, a exposição a patógenos no interior da bolsa periodontal pode propiciar as condições para a disseminação microbiana via hematogênica. Estudos experimentais prévios mostraram que a administração oral de P. gingivalis foi capaz de causar alterações na expressão gênica e níveis de citocinas no fígado (120,126), além de induzir aumento da concentração de lipídios em hepatócitos e aumento nos níveis de triglicérides (117).…”
