The majority of chronic infections are associated with mono- or polymicrobial biofilms, having a significant impact on the patients’ quality of life and survival rates. Although the use of medical devices revolutionized health care services and significantly improved patient outcomes, it also led to complications associated with biofilms and to the emergence of multidrug resistant bacteria. Immunocompromised patients, institutionalized or hospitalized individuals, elderly people are at greater risk due to life-threatening septic complications, but immunocompetent individuals with predisposing genetic or acquired diseases can also be affected, almost any body part being able to shelter persistent biofilms.
