Biofilm forming ability of the Enterococcus faecalis isolates in mono and dual biofilms. Numbers of the sessile cells of the E. faecalis isolates in mono and dual species biofilms were determined by plate counting assay. (a) The results of isolates from the urinary catheter samples, (b) The results of isolates from the urine samples. Results are means of at least three different experiments. Mono: only E. faecalis biofilms, Dual: E. faecalis and S. aureus biofilms, CFU: Colony forming unit,
*: Statistically significant
