The ability to form biofilms is considered as one of the key virulence factors of microorganisms. Studying the effect of physical factors, in particular, low-intensity radiation on microbial biofilms is important in view of the development of combined approaches to the therapy of pathological processes caused by infectious agents. The effect of LED radiation of the red-infrared spectrum on biofilm formation and formed biofilms of some opportunistic microorganisms was studied. It has been proven that irradiation of the studied microorganisms with LED radiation significantly increases their ability to form biofilms. However, no significant effect of radiation on already formed biofilms was noted. The obtained data confirm the dose-dependent nature of the effect of low-intensity radiation on the biological properties of microorganisms, as well as the significantly higher resistance of microbial biofilms to both chemical and physical factors, compared to planktonic forms.
