Ralstonia picketti, Ralstonia mannitolilytica, and Ralstonia insidiosa have recently been regarded as emerging pathogens of infectious diseases, in particular as the pathogens responsible for nosocomial infection in immunocompromised patients. Ralstonia species are Gram-negative bacilli that have increasingly been recognized as emerging nosocomial pathogens, particularly in immunocompromised hosts. Ralstonia Insidiosa is Gram-negative aerobic rod occuring in wet and moist environ-ment decribed as potential cause of nosocomial infections. Patients undergoing hemodialysis (HD) are also considered at-risk group to acquire Ralstonia infection. Introduction. Prevent the appearance of biofilms thanks to a unique and patented treatment combining a detergent base and a specific cocktail of enzymes.
