Abstract
Objective:To understand the bacterial contamination of air,elevator buttons,fingerprint machines,skin,and cell phones of a university during the epidemic period,and to provide reasonable suggestions for effectively reducing bacterial pollution during the epidemic period.By comparing the bacteriostatic effects of commonly used chemical disinfectants(Bromogeramine,Gentian violet,75%Alcohol,Iodine volt)and Chinese herbs(Scutellaria baicalensis,Peony bark)for skin-derived bacteria and cell phone-derived bacteria,to provide a reference for selection of disinfectants.Methods:Air bacteria were collected by the natural sedimentation method and bacteria from other sites were collected by the smear method,then cultured and counted for colony count to assess contamination.The bacteriostatic circle diameter was measured by the paper diffusion method to evaluate the bacteriostatic effect of four chemical disinfectants and two herbal medicines for skin-derived bacteria and cell phone-derived bacteria.Results:⑴The air bacteria test results of eight laboratories showed that one room was clean,six rooms were relatively clean,and one room was slightly polluted;The bacterial test results of eight elevator buttons showed that seven exceeded the standard;The bacterial test results of eight fingerprint machines showed that two exceeded the standard;Eight students tested for bacteria on their finger skin,and three of them exceeded the standard;The bacterial test results of 8 mobile phones showed that two exceeded the standard.⑵The antibacterial effects of chemical disinfectants and herbal medicines for skin-derived bacteria were:Bromogeramine＞Scutellaria baicalensis＞Gentian violet＞Peony bark＞Iodine volt＞Alcohol,and neosporin was the best.The antibacterial effects for cell phone-derived bacteria were:Gentian violet＞Bromogeramine＞Scutellaria baicalensis＞Iodine volt＞Peony bark＞Alcohol,and gentian violet was best.Conclusion:The air quality of the laboratories in the university was good,but the public elevator buttons and fingerprint machines belonging to bacterial contamination exceeded the standard.The relevant departments need to enhance the disinfection frequency and strengthen disinfection effect monitoring,and teachers and students need to strengthen hand disinfection after use.Students'finger skin and cell phones belonging to bacterial contamination also exceeded the standard.Students need to strengthen their own hand hygiene awareness and cell phone hygiene awareness.Bromogeramine,Gentian violet and Scutellaria baicalensis ranked in the top three for their antibacterial effects for skin-derived and cell phone-derived bacteria,and they can be used as disinfectants in daily life.Scutellaria baicalensis has shown good antibacterial effects,which can provide a reference for the development of disinfectants of traditional Chinese medicine.关键词
