DNA-microarrays identification of Streptococcus mutans genes associated with biofilm thickness.

abstract：BACKGROUND:The evolution of mycoplasmas from a common ancestor with Firmicutes has been characterized not only by genome down-sizing but also by horizontal gene transfer between mycoplasma species sharing a common host. The mechanisms of these gene transfers remain unclear because our knowledge of the mycoplasma mobile...
