摘要:

目的 建立銀離子水凝膠涂層導尿管的抑菌效力定量檢查方法。方法 根據(jù)《中華人民共和國藥典》2015年版微生物計數(shù)法(四部通則1105),以金黃色葡萄球菌、銅綠假單胞菌、大腸埃希菌、表皮葡萄球菌和白色念珠菌作為試驗菌株,以D/E中和肉湯作為中和劑,采用中和劑與薄膜過濾法聯(lián)合使用的方式對銀離子水凝膠涂層導尿管進行微生物計數(shù)方法適用性試驗。根據(jù)《中華人民共和國藥典》2015年版抑菌效力檢查法(四部通則1121),采用經(jīng)驗證的微生物計數(shù)方法定量測定銀離子水凝膠涂層導尿管對上述5種試驗菌的抑菌效力。結(jié)果D/E中和肉湯與薄膜過濾法聯(lián)合使用可以有效中和銀離子的抑菌活性,銀離子水凝膠涂層導尿管對上述5種試驗菌均具有較好的抑菌作用,抑菌率均能達到99%,且抑菌效力可持續(xù)至14 d。結(jié)論 采用D/E中和肉湯與薄膜過濾法聯(lián)合使用的方式建立適用于銀離子水凝膠涂層導尿管的微生物計數(shù)方法,可照此方法進行抑菌效力檢查中存活菌數(shù)的測定。建立的方法可用于銀離子水凝膠涂層導尿管抑菌效力的定量檢查。

objective To establish the antimicrobial effect quantitative test method for silver hydrogel coated catheter. Methods According to the requirements in the 2015 version of Chinese Pharmacopoeia(General Rule 1105), Staphylococcus aureus,Pseudomonas aeruginosa,Escherichia coli,Staphylococcus epidermidis and Candida albicans were used as the test strains,D/E neutralizing broth was used as neutralizer,the microbiological counting method applicability test was carried out by combined use of neutralizer and membrane filtration method. According to the requirements in the 2015 version of Chinese Pharmacopoeia(General Rule 1121), the antimicrobial effectiveness against the above five strains was mesured by the verified microbiological counting method. Results The antimicrobial activity of silver ions could be effectively neutralized by the combination of D/E neutralizer and membrane filtration method. The silver hydrogel coated catheter had good antimicrobial effect on the above five strains,and the antimicrobial effect could reach 99% and can last up to 14d. Conclusions The microbiological counting method for silver hydrogel coated catheters is established by using D/E neutralizer combined with membrane filtration method, which can be used to determine the number of viable bacteria in antibacterial effect test. The method we established can be used in the antimicrobial effect quantitative test method for silver hydrogel coated catheter.
