1117 MICROBIOLOGICAL BEST LABORATORY PRACTICES 优良微生物检测规范INTRODUCTION 介绍

Good laboratory practices in a microbiology laboratory consist of activities that depend on several principles: aseptic technique, control of media, control of test strains, operation and control of equipment, diligent recording and evaluation of data, and training of the laboratory staff. Because of the inherent risk of variability in microbiology data, reliability and reproducibility are dependent on the use of accepted methods and adherence to good laboratory practices.

优良微生物检测规范由一些活动组成，这些活动依赖于几个基本要素：无菌技术、培养基控制、检测用菌株控制、设备操作和控制、完善的记录和数据评估、化验室员工的培训。由于微生物数据具有天生的不确定性，数据的可靠性和重复性取决于是否使用被接受的方法，以及是否严格遵守化验室规范。

MEDIA PREPARATION AND QUALITY CONTROL 培养基制备和质量控制

Media Preparation 培养基制备

Culture media are the basis for most microbiological tests. Safeguarding the quality of the media is therefore critical to the success of the microbiology laboratory. Media preparation, proper storage, and quality control testing can ensure a consistent supply of high-quality media.

培养基是大多数微生物测试的基础。保证培养基的质量因而成为微生物实验室成功的关键。培养基的制备、合适的存贮和质量控制检测可以保证持续高质量培养基供应。

It is important to choose the correct media or components in making media based on the use of accepted sources or references for formulas. The manufacturer's formula and instructions for preparation routinely accompany dehydrated media and

ready-made media. Because different media types may have different preparation requirements (e.g., heating, additives, and pH adjustment), it is important to follow these instructions to ensure preparation of acceptable media quality. A certificate of analysis describing expiration dating and recommended storage conditions accompanies ready-made media, as well as the quality control organisms used in growth-promotion and selectivity testing of that media.

在制备培养基过程中使用已接受的来源或配方标准，选择正确的培养基或成份是非常重要的。一般生产商在供应培养基干粉和配制好的培养基时，其配方和配制指示都会随货发送。由于不同的培养基类型可能有不同的配制要求（例如，加热、添加剂，和pH值调节），重要的一点是需要遵守其提供的配制指示以保证配制出的培养基质量。如果是已制备好的培养基碟/瓶，随货会收到指明有效期和推荐的存贮条件的分析报告，以及促生产试验用微生物种类，和该培养基的选择性试验用微生物种类。

Water is the universal diluent for microbiological media. Purified Water is most often used for media preparation, but in certain cases the use of deionized or distilled water may be appropriate. Water of lesser quality should not be used for microbiological media preparation. The volume of the water used should be recorded.

水是通用的微生物培养基稀释剂。纯化水常用于培养基制备，但在某些情况下，也可以使用去离子水或蒸馏水。更低品质的水不应用于微生物培养基制备。水的用量应记录。Consistent preparation of media requires accurate weighing of dehydrated media or media constituents. A calibrated balance with the appropriate weight range for the ingredients should be used (See Weighing on an Analytical Balance1251). Clean weighing containers and tools (such as spatulas) should be used to prevent foreign substances from entering the formulation. The weight of the components should be recorded.

要保持培养基配制的一致性，需要对培养基干粉或培养基组份进行准确称量。应使用在所需称量范围内经过校正的天平（见1251分析天平称量）。应对称重容器和工具（例如料勺）进行清洁以保证无异物进入所配物料。各成份的重量应进行记录。Dehydrated media should be thoroughly dissolved in water before dispensing and sterilization. If heating is necessary to help dissolve the media, care should be taken not to overheat media, because all culture media, to a greater or lesser extent, are
