Shin’iseihaito (Xinyiqingfeitang) Suppresses the Biofilm Formation of Streptococcus pneumoniae In Vitro

Figure 1

SSHT inhibits the biofilm formation of S. pneumoniae in time-dependent manners. (a) S. pneumoniae was treated with or without SSHT (500 µg/mL) for 1–3 days, and its antibiofilm activity was quantified by crystal violet adsorption by measuring absorbance at 570 nm. Data shown represent the mean ± SD (). ; . NS: not significant. (b) Image of microplate. SSHT: Shin’iseihaito extract.
