Ultraviolet C light with wavelength of 222 nm inactivates a wide spectrum of microbial pathogens

UVC has been used to inactivate several pathogens. Unlike the conventional 254-nm UVC, 222-nm UVC is harmless to mammalian cells.To investigate the disinfection efficacy of 222-nm UVC against human pathogens which are commonly found in the environment and healthcare facilities.Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, Salmonella enterica subsp. serovar Typhimurium, Campylobacter jejuni, Bacillus cereus (vegetative cells...
