Characterization of biofilm formation by Enterococcus faecalis isolates derived from urinary tract infections in China.

ABSTRACT: Purpose. This study explored the prevalence and characteristics of Enterococcus faecalis biofilm formation by urinary tract infection (UTI) isolates in order to identify virulence factors associated with biofilm formation.Methodology. A total of 113 E. faecalis isolates were collected from UTI patients in Shenzhen, China. The isolates were subjected to multilocus sequence typing based on housekeeping genes. Biofilms were detected by crystal violet staining and the expression levels of the E. faecalis genes were detected by quantitative real-time PCR.Results/Key findings. The main sequence types (STs) were ST16 and ST179 with the ST16 isolates more likely to form strong biofilms than the ST179 isolates (P=0.008). Strong biofilm formation was
