从接轨的角度考虑,还是应该每个灭菌批都要做适用性检查。
之前实验室只有在新开瓶干粉培养基配制时才使用购自中检院的对照培养基,其余配制培养基时使用前一批次已验证合格的培养基作为对照。
摘自USP<71> STERILITY TESTS 无菌检查法
Suitability Tests 适合性试验
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.
通过在指定培养温度下将一部分培养基培养14天,来确认每一批已灭菌培养基的无菌状态。不得出现微生物生长。
GROWTH PROMOTION TEST OF AEROBES, ANAEROBES, and FUNGI
好氧菌、厌氧菌、霉菌的生长促进试验
Test each lot of ready-prepared medium and each batch of medium prepared either from dehydrated medium or
from ingredients1 . Suitable strains of microorganisms are indicated in Table 1.
检查每一批已经配制好的培养基和每一批用脱水培养基或配料制备的培养基1。适当微生物菌株见表1。 |
