Presence of virulence factor genes (gelE and esp) and biofilm formation in clinical Enterococcus faecalis and Enterococcus faecium isolated from urinary tract infection in Isfahan, Iran

In conclusion, we observed a high frequency of biofilm formation, esp and gelE genes in Enterococcoci strains isolated from UTIs. As an important result was a significant association between the presence of these two genes and biofilm production. Therefore, the new and more effective strategies should be applied to prevent and spread of these strains.
