聚维酮碘泡腾片控制菌检查方法的探讨

Study on the detection of controlled bacteria with povidone iodine effervescent tablets

目的探索聚维酮碘泡腾片控制菌检查方法,提高控制菌的检出率。方法聚维酮碘泡腾片崩解后采用淀粉吸附法和硫代硫酸钠中和法排除其抑菌作用,再按常规法对控制菌进行检测。结果聚维碘泡腾片控制菌检出率高,阳性对照菌生长良好。结论淀粉吸附法、硫代硫酸钠中和法均可用于聚维酮碘泡腾片控制菌的检查,提高控制菌的检出率。

Objective To study the detection of controlled bacteria with povidone iodine effervescent tablets, so as to in- crease the detection rate of controlled bacteria. Methods With the disintegration of povidone iodine effervescent tablets, the starch ad- sorption method and sodium thiosulfate neutralization method were used to remove bacteriostasis, and then conventional method was ap- plied to detect the controlled bacteria. Results Experiments showed that the detection rate of the controlled bacteria was high and the growth of the positive control bacteria was quite good. Conclusion The starch adsorption method and the sodium thiouslfate neutraliza- tion method could all be used for the detection of controlled bacteria with povidone iodine effervescent tablets.
