Resumo Inglês:
The present study aimed to evaluate xylitol’s antimicrobial and anti-adherence activities on Escherichia coli (ATCC
8739) and on another clinical strain enteropathogenic E. coli (EPEC). In vitro minimum inhibitory concentration
(MIC) test and adhesion assays were performed using 0.5, 2.5 and 5.0% xylitol. It was found that xylitol did not
have antimicrobial properties on these strains. The scanning electron microscopy (SEM) demonstrated that the
slides treated with xylitol had a significant reduction in the number of bacilli and the inhibition of microbial
adhesion was probably the xylitol’s mechanism of action. Xylitol could be a possible alternative on the control of E.
coli infections.
