PROBIOTIC-BASED SANITATION AS ALTERNATIVES TO CHEMICAL DISINFECTANTS

It is known that any surfaces in environment of healthcare organizations are a reservoir for microorganisms and contribute to transmission of pathogens, increasing the risk of cross-contamination through indirect contact with the patient. Wide and not always rational use of chemical disinfectants ca...
