2.6.1. STERILITY 2.6.1 无菌检查法
The test is applied to substances, preparations or articles which, according to the Pharmacopoeia, are required to be sterile. However, a satisfactory result only indicates that no contaminating micro-organism has been found in the sample examined in the conditions of the test.
本检查方法适用于按照药典要求应当无菌的原料、制剂或其他物质。但是，如果按照本无菌检查法的结果符合要求，仅表明在该检查条件下未发现微生物污染。
PRECAUTIONS AGAINST MICROBIAL CONTAMINATION 微生物污染防范
The test for sterility is carried out under aseptic conditions. In order to achieve such conditions, the test environment has to be adapted to the way in which the sterility test is performed. The precautions taken to avoid contamination are such that they do not affect any micro-organisms which are to be revealed in the test. The working conditions in which the tests are performed are monitored regularly by appropriate sampling of the working area and by carrying out appropriate controls.
无菌检测试验应在无菌的条件下进行。为了达到这样的条件，检测环境应当与无菌检测的操作要求相适应。避免污染的防范措施应当不对本检查方法进行检测的微生物造成影响（应并不影响用本检查法检测的微生物）。通过对工作区域的适当取样以及进行适当的控制来对无菌检查的工作环境进行例行监测。

negative controls are included. The technique of membrane filtration is used whenever the nature of the product permits, that is, for filterable aqueous
preparations, for alcoholic or oily preparations and for preparations miscible with or soluble in aqueous or oily solvents provided these solvents do not have an antimicrobial effect in the conditions of the test.
供试品的无菌检查可以采用薄膜过滤法或培养基直接接种法进行测定，应当包含适当的阴性对照。如果供试品中的溶剂在测定条件下无抗微生物活性，当产品性质允许时，薄膜过滤法可广泛应用于可过滤的水性制剂、醇溶性或油溶性制剂以及可与水性或油性溶剂混合或溶解的制剂。
Membrane filtration. Use membrane filters having a nominal pore size not greater than 0.45 μm whose effectiveness to retain micro-organisms has been established. Cellulose nitrate filters, for example, are used for aqueous, oily and weakly alcoholic solutions and cellulose acetate filters, for example, for strongly alcoholic solutions. Specially adapted filters may be needed for certain products, e.g. for antibiotics.
薄膜过滤法 使用标示孔径不大于0.45μm的、经确定可有效截留微生物的膜过滤器。比如，硝酸纤维素过滤器可用于水性、油性以及弱醇性溶液，而醋酸纤维素可用于强醇性溶液。对于某些产品，比如抗生素，可能需要特定的过滤器。
The technique described below assumes that membranes about 50 mm in diameter will be used. If filters of a different diameter are used the volumes of the dilutions and the washings should be adjusted accordingly. The filtration apparatus and membrane are sterilised by appropriate means. The apparatus is designed so that the solution to be examined can be introduced and filtered under aseptic conditions; it permits the aseptic removal of the membrane for transfer to the medium or it is suitable for carrying out the incubation after adding the medium to the apparatus itself.
以下描述的方法中使用的是50mm的薄膜，如果使用不同尺寸的薄膜，稀释和冲洗的体积应当进行相应调节。过滤的设备和薄膜应当采用适当的方式进行灭菌。应对设备进行设计，以便供试品溶液可以加入并在无菌条件下进行过滤；设备应支持无菌状态下去除薄膜来进行培养基转运，或者适合将培养基加入设备中后进行培养。

水性溶液 如合适，将少量适当的无菌稀释剂（比如1 g/L中性肉或酪蛋白胨，pH 7.1 ± 0.2）转至设备的滤膜上并进行过滤。在产品为抗生素等情形中，稀释剂可以包含适当具有中和作用和/或具有灭活作用的物质。
Transfer the contents of the container or containers to be tested to the membrane or membranes, if necessary after diluting to the volume used in the method suitability test with the chosen sterile diluent but in any case using not less than the quantities of the product to be examined prescribed in Table 2.6.1.-2. Filter immediately. If the product has antimicrobial properties, wash the membrane not less than 3 times by filtering through it each time the volume of the chosen sterile diluent used in the method suitability test. Do not exceed a washing cycle of 5 times 100 mL per filter, even if during the method suitability test it has been demonstrated that such a cycle does not fully eliminate the antimicrobial activity. Transfer the whole membrane to the culture medium or cut it aseptically into 2 equal parts and transfer one half to each of 2 suitable media. Use the same volume of each medium as in the method suitability test. Alternatively, transfer the medium onto the membrane in the apparatus. Incubate the media for not less than 14 days.
将供试品容器内容物转至滤膜表面，必要时可采用选定的无菌稀释剂稀释至方法适用性检测中使用的体积，但任何时候所检测的供试品的数量均不得低于表2.6.1.-2规定的量。立即过滤。如果供试品具有抗微生物活性，采用选用的稀释剂过滤冲洗滤膜至少3次，每次冲洗的体积按照方法适用性检测中使用的体积。每个冲洗循环不要超过5次及100mL/次，即使方法适用性检测已证明这样的循环并不能完全消除供试品的抗微生物活性。转移整个滤膜到培养基中或者将其在无菌条件下剪切成大小相同的量块然后将每一部分分别转移到2种适合的培养基中。每种培养基使用的体积和方法适用性检测中的一致。也可以将培养基加入设备中的滤膜上。所得培养基培养时间不得少于14天。

对无菌检查中分离的微生物进行特性检查后发现，这或这类微生物的生长明确源于无菌检查操作方法中所使用的材料和/或技术。
If the test is declared to be invalid it is repeated with the same number of units as in the original test. If no evidence of microbial growth is found in the repeat test the product examined complies with the test for sterility. If microbial growth is found in the repeat test the product examined does not comply with the test for sterility.
如果该测定被宣布无效，应采用和初次测定时同样数量单位的样品进行重复检测。如果重复检测时未发现有微生物生长的证据，则检测样品符合无菌检测的要求。如果发现有微生物生长的证据，则检测样品不符合无菌检查的要求。

APPLICATION OF THE TEST TO PARENTERAL PREPARATIONS, OPHTHALMIC AND OTHER NON-INJECTABLE PREPARATIONS REQUIRED TO COMPLY WITH THE TEST FOR STERILITY
无菌检查在要求符合无菌要求的注射药品、眼用药品以及其它非注射药品中的应用
When using the technique of membrane filtration, use, whenever possible, the whole contents of the container, but not less than the quantities indicated in Table 2.6.1.-2, diluting where necessary to about 100 mL with a suitable sterile solution, such as 1 g/L neutral meat or casein peptone.
当使用薄膜过滤法时，只要可能，应当使用容器内的全部内容物，供试品数量不得少于表2.6.1.-2中规定数量。必要时可以选用1 g/L中性肉或酪蛋白胨等合适无菌溶液稀释到100 mL。
When using the technique of direct inoculation of media, use the quantities shown in Table 2.6.1.-2, unless otherwise justified and authorised. The tests for bacterial and fungal sterility are carried out on the same sample of the product to be examined.
当使用培养基直接接种法时，供试品数量不得少于表2.6.1.-2中规定数量，除非另有依据并获得许可。对细菌和真菌的无菌检查采用同样的检测样品进行考察。
