目的
2
负载多功能纳米硒聚维酮碘(PVP-I@Se)消毒剂对金黄色葡萄球菌(SA)、耐甲氧西林金黄色葡萄球菌(MRSA)的杀菌效果,为皮肤手术部位消毒提供实验依据。
方法
2
实验分为PVP-I组(对照组)与PVP-I@Se组(实验组),两组的碘浓度梯度相同,分别为50、75、100、200和400 μg/mL,实验组硒浓度2 μg/mL,对照组不添加硒,比较两组不同的消毒液对SA、MRSA的消毒效果,检测指标包括最低抑菌浓度(MIC)和最低杀菌浓度(MBC);碘浓度50 μg/mL时的最短杀菌时间;碘浓度200 μg/mL、400 μg/mL时的抑菌圈大小。
结果
2
对照组对SA、MRSA的MIC均为79.17 μg/mL、实验组分别为54.17和70.83 μg/mL。而对照组对SA、MRSA的MBC分别为129.17和150.00 μg/mL,实验组分别为70.83和87.50 μg/mL。碘浓度50 μg/mL时,对照组对SA、MRSA的最短杀菌时间为130 s、140 s,实验组分别为65 s、75 s。碘浓度200 μg/mL时,对照组对SA、MRSA的抑菌圈直径分别为7.67 mm、8.33 mm,实验组均为9.50 mm。碘浓度400 μg/mL时,对照组对SA、MRSA的抑菌圈直径分别为9.00 mm、9.33 mm,实验组分别为11.67 mm、12.00 mm。
结论
2
在聚维酮碘浓度为50、75、100、200和400 μg/mL时,分别加入浓度为2 μg/mL的硒,可增强其对SA、MRSA的杀菌效果、缩短作用时间。硒(SeNPs)加入PVP-I对SA、MRSA 的杀菌效果均有增效作用。但增敏效果SA较MRSA显著。MRSA的增效作用对碘浓度(400 μg/mL)需求较高。为临床精准选用消毒剂的浓度和作用时间,降低临床皮肤手术部位感染提供理论依据。
Objective
2
To investigate the bactericidal effect of loaded multifunctional povidoneiodine-nanometer selenium (PVP-I@Se) disinfectant on
Staphylococcus aureus
(SA) and methicillin-resistant
Staphylococcus aureus
(MRSA), and to provide an experimental basis for the reduction of surgical site infection (SSI).
Methods
2
The control group was the povidone iodine (PVP-I) group with different concentrations of iodine (50, 75, 100, 200 and 400 μg/mL). The PVP-I@Se group (experimental group) was the PVP-I group further supplemented with 2 μg/mL Selenium nanoparticles (SeNPs). Then we compared the bactericidal effect of the two groups of disinfectant solutions on SA and MRSA by examining the minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC), the shortest sterilization time at a concentration of 50 μg/mL iodine and the inhibition zone diameters at concentrations of 200 μg/mL and 400 μg/mL iodine.
Results
2
MIC values of PVP-I against SA and MRSA were both 79.17 μg/mL, and those of PVP-I@Se were 54.17 and 70.83 μg/mL, respectively. MBC values of PVP-I against SA and MRSA were 129.17 and 150.00 μg/mL, respectively, and those of PVP-I@Se were 70.83 and 87.50 μg/mL, respectively. At a concentration of 50 μg/mL iodine, the shortest sterilization time of PVP-I for SA and MRSA was 130 s and 140 s, respectively, and that of PVP-I@Se was 65 s and 75 s, respectively. At a concentration of 200 μg/ml iodine, the inhibition zone diameters of PVP-I for SA and MRSA were 7.67 mm and 8.33 mm, and those of PVP-I@Se were both 9.50 mm. At a concentration of 400 μg/mL iodine, the inhibition zone diameters of PVP-I for SA and MRSA were 9.00 mm and 9.33 mm, and those of PVP-I@Se were 11.67 mm and 12.00 mm, respectively.
Conclusions
2
PVP-I with different concentrations of 50, 75, 100, 200 and 400 μg/mL iodine supplemented with 2 μg/mL SeNPs have better and faster bactericidal effect on SA and MRSA. When combined with SeNPs, PVP-I can enhance the bactericidal activity against SA and MRSA, but with better sensitizing effect on SA than MRSA and higher demand of iodine concentration (400 μg/mL) for sensitizing effect on MRSA. This study provides a theoretical basis for selecting optimal concentration and action time of the disinfectant, thus reducing SSI.
