Abstract

In order to establish the meaning of data generated in antimicrobial agent susceptibility tests, it is necessary to develop internationally harmonised interpretive criteria. Currently, such criteria have not been developed for data generated in studies of the susceptibility of the fish pathogen Yersinia ruckeri. This work generated the data that would be required to set epidemiological cut-off values for the susceptibility data of this species that had been generated using a standardised disc diffusion method that specified the use of Mueller Hinton agar and incubation at 22°C for 24-28 h. Using this method, sets of inhibition zones data for 4 antimicrobial agents were generated by 3 independent laboratories. The data from these laboratories were aggregated and analysed using the statistically based normalised resistance interpretation. For ampicillin, florfenicol, oxytetracycline and trimethoprim-sulfamethoxazole the cut-off values calculated by this analysis were ≥16, ≥23, ≥24 and ≥30 mm, respectively. Evidence is presented demonstrating that the data for these 4 agents was of sufficient quantity and quality that they could be used by the relevant authorities to set internationally harmonised, consensus epidemiological cut-off values for Y. ruckeri.

用标准化方法生成的罗氏耶尔森菌盘扩散数据的流行病学临界值。

为了确定抗菌剂药敏试验产生的数据的意义，有必要制定国际统一的解释标准。目前，还没有为鱼类病原体 Yersinia ruckeri 的药敏性研究中产生的数据制定此类标准。这项工作生成了为该物种药敏性数据设定流行病学临界值所需的数据，这些数据是使用标准化的盘扩散方法生成的，该方法规定使用穆勒欣顿琼脂，并在 22°C 孵育 24-28 小时。对这些实验室的数据进行汇总，并使用基于统计学的归一化耐药性解释进行分析。对于氨苄西林、氟苯尼考、土霉素和三甲双胍-磺胺甲噁唑，该分析计算出的临界值分别为≥16、≥23、≥24 和≥30 毫米。有证据表明，这 4 种制剂的数据在数量和质量上都足以供有关当局用于制定国际统一的、一致的拉氏酵母菌流行病学临界值。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
