Media for Penicillins or Cephalosporins 用于青霉素和头孢菌素的培养基
Where sterility test media are to be used in the Direct Inoculation of the Culture Medium method under Test for Sterility of the Product to be Examined, modify the preparation of Fluid
Thioglycollate Medium and the Soybean–Casein Digest Medium as follows. To the containers of each medium, transfer aseptically a quantity of -lactamase sufficient to inactivate the amount of antibiotic in the specimen under test. Determine the quantity of -lactamase required to inactivate the antibiotic by using a -lactamase preparation that has been assayed previously for its penicillin- or cephalosporin-inactivating power. [NOTE—Supplemented -lactamase media can also be used in the membrane filtration test.]
当无菌检查培养基用于供试产品无菌检查项下的培养基直接接种法时，按如下内容变更巯基醋酸盐液体培养基和大豆-酪蛋白消化物培养基的 制备方法。向每一种培养基的容器中，以无菌操作转移足够灭活供试样品中所存在抗生素的 -内酰胺酶。使用此前已经对其青霉素或头孢菌素灭活能力进行了测定的 -内酰胺酶配制品，来测定灭活该抗生素所必需的 -内酰胺酶数量。[注意：补充的 -内酰胺酶培养基也可以用于膜过滤试验]
Alternatively (in an area completely separate from that used for sterility testing), confirm that an appropriate amount of -lactamase is incorporated into the medium, following either method under Validation Test, using less than 100 colony-forming units (cfu) of Staphylococcus aureus (see Table 1) as the challenge. Typical microbial growth of the inoculated culture must be observed as a confirmation that the -lactamase concentration is appropriate.
或者（在与无菌试验所用场所彻底隔离的区域中），按照验证试验项下的任意一种方法，使用少于100个菌落（cfu）的金黄色葡萄球菌（见表1）作为验证菌，来确认适当数量的 -内酰胺酶已经被整合到该培养基中。必须观测到接种后培养物中出现典型微生物生长，才能确认 -内酰胺酶浓度是适当的。

The media used comply with the following tests, carried out before, or in parallel, with the test on the product to be examined.
所使用的培养基须符合下列试验，这些试验应在检验供试产品之前或者同时进行。
STERILITY 无菌状态
Confirm the sterility of each sterilized batch of medium by incubating a portion of the media at the specified incubation temperature for 14 days. No growth of microorganisms occurs.
