[In vitro activity of baicalin against non-albicans Candida biofilms].
OBJECTIVE
To investigate the effects of baicalin against Candida glabrata, C. parapsilosis, C. krusei and C. guilliermondii biofilms.


METHODS
96-well microtitre plates were used to set up the biofilms; microdilution method was applied to detect minimal inhibitory concentration (MIC) of baicalin for the four non-albians Candida, and XTT reduction assay was adopted to determine sessile minimal inhibitory concentration (SMIC) of baicalin against the four isolates and to detect the effects on adhesion of the fungal cells.


RESULTS
MICs of baicalin for the four non-albians Candida cells were 125, 250, 125, 62.5 mg L(-1), respectively. The four non-albians Candida could form mature biofilms on 96-well microtitre plates. SMIC50 of baicalin for the four isolates were > 1000, 500, 125, 250 mg x L(-1), respectively. SMIC80 for the four isolates were greater than or equal to 1000 mg x L(-1). Baicalin showed potent inhibitory effects on adhesion of the four non-albians Candida cells.


CONCLUSIONS
Baicalin displays substantial inhibitory effects on C. parapsilosis, C. krusei and C. guilliermondii biofilm.
