Research Report on the Effect of Air Disinfection of Gu's Traditional Chinese Medicine Disinfection Column
To investigate the antibacterial and antiviral effects of Gu's traditional Chinese medicine disinfection column,the antibac-terial and antiviral effects of the traditional Chinese medicine disinfection column on Escherichia coli,Staphylococcus aureus,Acine-tobacter baumannii,Pseudomonas aeruginosa,Klebsiella pneumoniae and FM1 strain of influenza A virus were tested by direct fumi-gation in an air disinfection cabinet.The bacterial was inoculated on the culture plate and placed in the cabinet together with the burning disinfection column,the plate was removed after 30 min and incubated at 37 ℃ for 48 h.The influenza virus hemagglutina-tion titer was detected before and after the action of the traditional Chinese medicine disinfection column.Direct fumigation was per-formed in the student dormitory area,and samples were taken at 0,0.5,1,2 and4 h,and incubated at 37 ℃ for 48 h to count the number of bacteria colony respectively.The quantity of natural bacteria in the air before and after the action of traditional Chinese medicine disinfection column was compared.The results showed the traditional Chinese medicine disinfection column had high signi-ficant inhibitory effects on Escherichia coli,Staphylococcus aureus,Acinetobacter baumannii,Pseudomonas aeruginosa and Klebsiella pneumoniae,with which the inhibitory effects of the traditional Chinese medicine disinfection column were comparable to 2％perox-yacetic acid(P＞0.5).The traditional Chinese medicine disinfection column could be obviously removed the natural bacteria in the air,there is a very significant inhibition effect after 0.5 h disinfection.The quantity of bacteria colony collected from the air was decreased by 70％after 0.5 h disinfection.The hemagglutination titer of viral influenza virus decreased significantly before and after disinfection,and 99％of viruses lost their infectivity after 1 h disinfection.The traditional Chinese medicine disinfection column have a scavenging effect on bacteria,natural bacteria in the air and influenza virus,and are more acceptable to patients than peroxyacetic acid,and could be used for air disinfection in the presence of people.
