不同微生物对消毒剂的抗性也各不相同。它们的顺序从大到小的排列如下：

化学消毒剂按他们的化学型分类。其中包括醛，醇，卤素，过氧化物，季胺类化合物，和酚类化合物。

抗微生物化学试剂可分为三类：杀菌剂，消毒剂和杀孢子剂。这里列出的是通常与每个类别相关联的试剂类型。

由于蒸发快、残留低的特点，消毒已被带入APA的物品时应使用醇类（即异丙醇和乙醇）化学试剂。除非与材料存在相容性问题，应使用70％异丙醇（IPA）代替70％乙醇（ EtOH），因为异丙醇的杀菌作用被认为比乙醇稍大。虽然醇类对活细胞具有相对较好的杀菌活性，但醇类的快速挥发显著降低了其效力。醇类杀菌剂对孢子无效。

酚类和季铵化合物对活细胞具有广谱杀菌活性。这些化学物质典型特征会带来表面残留。紧随它们的使用应清除该部分残留，例如通过异丙醇擦拭清除。

次氯酸钠（漂白剂）和过氧化氢/过氧乙酸化合物是广泛使用的杀孢子剂。过氧化氢也可用于（通常在6％浓度）提供对霉菌和一些孢子形式微生物提供抗菌活性。过氧化物比醇类抗菌活性更高，分解后形成水和氧气，不产生留残。当消毒程序要求清除孢子类微生物时应采用化学杀孢子剂。不幸的是，除过氧化氢外这些化学品均有一定残留。

New suppliers and new antimicrobial chemical agents for use in the disinfection program should be qualified prior to use following established procedures. A satisfactory audit, qualification testing, and a clearly defined
Certificate of Analysis (CoA) are important aspects to be considered as part of the qualification. If changes occur in the agent\'s formulation, packaging, or manufacturing site, an evaluation should be performed to determine if requalification is required.

用于消毒程序的新的供应商和新的杀菌化学试剂应在使用前根据建立的程序进行确认。令人满意的审计、确认测试和清楚定义的检验报告（ COA）被认为是确认中的重要部分。如果试剂的配方、包装或生产场所有所变更，则应进行评估以确定是否需要重新确认。

When choosing a new antimicrobial chemical agent from a supplier, evaluate the supplier\'s:

In evaluating supplier information related to the efficacy of an antimicrobial chemical agent, it is important to understand the testing methodology and standards used. These often vary depending on where the agent was registered and the claims made regarding its use. 
在评估关于杀菌化学试剂有效性的供应商信息时，了解所用的测试方法和标准非常重要。这些通常根据试剂注册地不同，以及关于其用途的声明而有差异。

Depending on the specific use of the antimicrobial chemical agent and experience with the specific supplier, an audit may need to be performed. Extra attention should be given to the following during an audit:

根据杀菌化学试剂的特定用途和特定供应商的经验，可能需要进行审计。在审计中需要注意以下方面：

Environmental control and cleaning of the manufacturing or packaging area and equipment used to manufacture the antimicrobial chemical agent.
用于生产杀菌化学试剂的生产或包装区域和设备的环境控制和清洁

Qualification testing of a new antimicrobial chemical agent should include both laboratory and insitu testing. Chemical analysis of the actives and microbial efficacy testing should be performed.
对一个新的抗菌化学试剂的确认测试应包括化验室和现场测试。要进行活性化学分析以及微生物有效性测试。

Chemical analysis of the actives may be provided by the vendor or, alternatively, performed in-house or by a qualified contract laboratory using the vendor\'s method. Microbial efficacy testing, whether in suspension or in
carrier studies, should be performed in-house or by a qualified contract testing laboratory.
活性化学分析可以由供应商提供，或者内部测试，或由一个经过确认的合同化验室使用供应商的方法进行测试。微生物有效性试验，如果是在混悬液中或在载体研究中，应内部进行测试，或由经过确认的第三方化验室进行测试。

The antimicrobials chemical agents used for testing should be close to or beyond their stated in-use expiration date (this should take into account a ready to use and/or a use dilution prepared from a concentrate expiry). Testing should be done in replicate on multiple lots of the antimicrobial chemical agent where applicable. It should be noted that significant registration testing on multiple lots of the agent is performed by the company registering the product to ensure product consistency between lots and stability throughout the stated shelf life.
用于测试的抗菌化学试剂应邻近或超出其使用有效期（这里要考虑直接使用和/或稀释使用时浓缩液的有效期）。如果可以的话，应对多个批次进行平行测试。要注意的是对多批试剂的重要的注册测试是由注册公司来进行的，以确保产品不同批次之间的一致性，以及其所声明的整个货架期的稳定性。

Additional qualification may be performed if changes in product formulation or packaging or site investigations deem it necessary. Information supporting the qualification includes the following seven areas:

Efficacy Testing 

有效性测试

The demonstration of antimicrobial chemical agents to provide their respective kills is a function of the concentration of microorganisms present, the type of microorganisms, the choice of agent, the concentration of the agent, the porosity or texture of the surface to be cleaned, the method of application, and the contact time.Routinely, the agent used should be effective against the normal microbial vegetative flora recovered from the facility. Many efficacy testing guidelines, such as the Association of Official Analytical Chemist (AOAC), suggest high microorganism inoculum levels requiring longer contact times to destroy the population of cells . As the normal clean room bioburden level is very low, the inoculum levels for testing would ideally depict levels seen in the controlled area. As this would not be practical in a test environment ahigher inoculum level should be used and should not exceed 105. The antimicrobial chemical agent used within the industry can be broken into three general areas: sanitizers, disinfectants, and sporicides.
抗菌化学试剂杀灭效果是被杀灭微生物浓度、微生物类型、试剂选择、试剂浓度、要清洁的表面的孔隙度或质地、所使用的方法以及接触时长的函数。一般来说，所用的试剂应对从设施中回收到的常规微生物植物群落有效。许多有效性测试指南，例如美国分析化学家协会（ AOAC），建议高浓度微生物接种需要更长的接触时长以摧毁细胞群。由于常规洁净间生物负载水平非常之低，测试的接种水平理想地描述了受控区域所见水平。由于这种情况在测试环境中不现实，需要使用更高的接种水平，应超出105。行业内所用的抗菌化学试剂可以分为三个常规区域：灭菌剂、消毒剂和杀孢子剂。

Sanitizers 

灭菌剂

Sanitizers provide minimal reduction in thirty seconds to ten minutes and are often used for low levels of vegetative microorganisms. The type of sanitizer will dictate the appropriate contact time required. Alcohol is an example of a commonly used sanitizer.
杀菌剂提供在30秒到10分钟最小减少量，通常用于低水平的植物性微生物。灭菌剂的类型决定了所需适当的接触时长。乙醇是常用的灭菌剂的例子。

Disinfectants

 消毒剂

Disinfectants exhibit a higher level of efficacy than sanitizers, and their kill is dependent on the inoculums and the contact time. Disinfectants will typically kill vegetative microorganisms with the exception of spore-forming microorganisms. Examples include quaternary ammonium compounds and phenolics.
消毒剂比灭菌剂具有更高的有效性，其杀灭性与接种水平和接触时长无关。消毒剂一般会杀灭植物性微生物，孢子形态除外。消毒剂例子包括季胺盐和酚醛物。

Sporicides 

杀孢子剂

Sporicides provide up to a total kill depending on the inoculums and the wet contact time and will kill bacterial spore formers as well as mold. Products commonly used today include bleach, hydrogen peroxide, and a mixture of hydrogen peroxide and peracetic acid.
杀孢子剂提供全面杀灭性，其杀灭能力与接种水平、湿润接触时长有关，能杀灭细菌孢子形态以及霉菌。现今常用产品包括漂白剂、过氧化氢、过氧化氢和过氧乙酸混合物。

In general, contact or dry times in qualification studies should not exceed 120 seconds for alcohols (70% isopropanol and 70% denatured ethanol) and 10 minutes for disinfectants and sporicides. Longer contact times may be required based on the specific chemical agents used.
一般来说，在确认研究中接触时长或干燥时长，乙醇（ 70%异丙醇，和70%变性乙醇）应超过120秒钟，消毒剂和杀孢子剂应超过10分钟。如果所用的是特定的化学试剂，可能需要更长的接触时长。

Methods to demonstrate efficacy include in-suspension and surface carrier (coupon) studies. In general, a total of three antimicrobial chemical agents (sanitizer, disinfectant, or sporicide) are all that would be qualified within the typical biopharmaceutical or pharmaceutical facility. While historically it was thought that a wide array of disinfectants were required to minimize the buildup of facilityresistant microorganisms, this is no longer a widely
held belief.
证明有效性的方法包括悬浮液和表面载体（样本）研究。一般来说，三种抗菌化学试剂（杀菌剂、消毒剂或杀孢子剂）的总合都要在典型的生物药品或药品设施里进行确认。历史上曾经有过想法需要宽范围的消毒剂来最大程度减少设施耐药菌的累积，但现在这种想法已不再广泛流行了。
