不是都建议一种杀孢子剂和消毒剂轮换使用了。何必用两种酚消毒剂呢。PDA都在TR70里说了,不认为消毒剂能真的导致微生物耐受。复制下原文
To date, there is no conclusive published test data proving such development of resistance by organisms to these agents. Resistance to antibiotics is usually acquired through modification of a single gene (or acquisition of a single gene) that blocks the very specific action of the antibiotic. The antimicrobial agents typically employed in clean rooms continue to be effective because they have numerous effects on a number of aspects of cellular physiology. This means that multiple mutations would be required in a short period of time (e.g., five-minute contact time) with exposure to low numbers of cells typically found in a clean room to overcome their detrimental effects. As such, resistance of a cell to agents used in the disinfection process would be highly unlikely given the environmental conditions and low cell numbers.
迄今为止,尚没有已发表的结论性试验资料来证明微生物对这些产品产生耐受。对抗生素的耐受通常是通过对一个单一基因的修饰获得的(或获得一个单一的基因),从而阻断了抗生素的特定作用。洁净室中使用的抗微生物试剂持续有效,因为其对一系列细胞生理活性具有多种作用。这意味着洁净室发现的少量微生物需在较短时间内(如5分钟接触时间)完成多次突变,以克服抗微生物试剂的不利作用。因此,考虑到环境因素和较低的微生物数量,微生物对消毒使用的试剂产生耐受性是极不可能的。
