ABSTRACT
OBJECTIVE:To establish a method of microbial limit test for Ofloxacin gel. METHODS:Test sample solutions were prepared by MnSO4,CaCl2 and MgCl2 gelout with different concentrations,the numbers of bacteria and control bacteria were detected by membrane filtration method,and the numbers of molds and yeasts were determined by conventional method. RE-SULTS:The conventional method showed the recoveries of Candida albicaus and Aspergillus niger were more than 70% after not treated by gel breaker;the membrane filtration method showed the recoveries of Escherichia coli,Staphylococcus aurus and Baci-lus subtilis were more than 70% after treated by 5% MnSO4,3% CaCl2 and 1% MgCl2;the membrane filtration method could de-tect the control bacteria after treated by gel breaker. CONCLUSIONS:Gel breaker with appropriate concentrations can effectively eliminate the antibacterial activity of Ofloxacin gel. The established method is suitable for its microbial limit test.
