summary

Enterococci are often responsible for causing hospital infections including urinary tract infections. They naturally colonize lower intestinal tract, oral cavity and genitourinary tract. It is suggested that the most nosocomial infections are caused by bacteria producing biofilm, which enable them surviving in urinary tract and avoiding immunological response of the host. The main pathogenicity factors of enterococci are: cytolisine, aggregation substance, gelatinase, surface protein Esp. The hospital environment may play an important role in transmission of infections. Epidemiological data have suggested that spreading of enterococci takes place by hands, clothes of medical service workers and medical equipment surfaces, where bacteria can survive very long. Enterococci are most often isolated from urinary tract infection cases of which 14.6% cases were polymicrobial. These bacteria cause about 15% infections in chronic cathetered patients. A shorter time of catheterization may reduce frequency of bacteriuria and necessity of using antibiotics. An emerging vancomycin-resistant enterococcal isolates and increasing level resistance to peniciline and aminoglycosides considerably limits therapeutical options. So, the prevention of vancomycin-resistant Enterococcus (VRE) colonisation and infection should be very important for clinicians because of decreasing patients' mortality, counteracting resistance emerging among S. aureus and decreasing health care costs.
