And the third is that this quiescent state is actually necessary for the animal's well-being and survival.

第三，这种静止期对动物的健康和生存来说是必不可少的。”

The oral microbiota is found in saliva, the surface of gum tissue and teeth, and in biofilms which are basically layers of goop-like material made of exopolysaccharides or EPS within which bacteria survive in a quiescent or slow-growing state.

口腔微生物群存在于唾液、牙龈组织和牙齿表面及生物膜中；生物膜是种主要由胞外多糖（EPS）组成的黏液状物质；细菌在其中处于静止或者缓慢增长状态。
