    Abstract:

    ObjectiveTo detect the disinfection and sterilization effect of  A/B type ultraviolet (UV) lamp on closestool. MethodsCarrier quantitative germicidal test  was performed, according to explaination of the  product, UV lamp irradiated for 15, 20, 25, 30, 35 minutes respectively on Staphylococcus aureus, Escherichia coli, Candida albicans and Bacillus subtilis on the carriers; onthespot disinfection test was also performed, before and after turning on the VU lamp for scheduled  time, samples were taken with cotton swab smear method, live bacterial counts were calculated.ResultsCarrier quantitative germicidal test showed that the average killing logarithm value of Staphylococcus aureus, Escherichia coli, Candida albicans and Bacillus subtilis were all≥3.00.  Onthespot disinfection test of 30 samples showed that the average killing logarithm value was 3.57, killing logarithm value of natural bacteria were all >1.00. ConclusionThe disinfection and sterilization effect of the  UV lamp on the A/B  type  closestool  is qualified.
