These MICs were within the limits previously reported for strains isolated in the United States. The range of MICs of rifabutin for Taiwanese strains was 0.015 to 0.125 \u00b5g\/ml; ciprofloxacin, 0.25 to 2.0 \u00b5g\/ml; ofloxacin, 0.5 to 2.0 \u00b5g\/ml. On the basis of an evaluation of the highest broth-determined MICs found in this and in a previous study, we suggest that the following MICs, when determined in 7H12 broth radiometrically, should be used as breakpoints to classify the strain as \u201csusceptible\u201d: for rifabutin, 0.125 \u00b5g\/ml or less; for ofloxacin and ciprofloxacin, 2.0 \u00b5g\/ml or less.<\/jats:p>","DOI":"10.1164\/ajrccm\/140.4.987","type":"journal-article","created":{"date-parts":[[2013,4,4]],"date-time":"2013-04-04T17:10:25Z","timestamp":1365095425000},"page":"987-989","source":"Crossref","is-referenced-by-count":29,"title":["Minimal Inhibitory Concentrations of Rifabutin, Ciprofloxacin, and Ofloxacin against\n                    <i>Mycobacterium tuberculosis<\/i>\n                    Isolated before Treatment of Patients in Taiwan"],"prefix":"10.1093","volume":"140","author":[{"given":"Chung-Hua","family":"Chen","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jen-Fu","family":"Shih","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pamela J.","family":"Lindholm-Levy","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leonid B.","family":"Heifets","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[1989,10,1]]},"reference":[{"key":"p_5","first-page":"309","volume":"131","author":"O'Brien RT","year":"1985","journal-title":"Am Rev Respir Dis"},{"key":"p_14","doi-asserted-by":"crossref","first-page":"719","DOI":"10.1164\/ajrccm\/137.3.719","volume":"137","year":"1988","journal-title":"Rev Respir Dis"},{"key":"p_17","first-page":"575","volume":"16","year":"1985","journal-title":"Chemother"},{"key":"p_20","first-page":"345","volume":"4","year":"1985","journal-title":"Microbiol"},{"key":"p_35","first-page":"II-5","volume":"27","year":"1985","journal-title":"Agents Chemother"},{"key":"p_38","first-page":"402","volume":"123","year":"1981","journal-title":"Am Rev Respir Dis"},{"key":"p_42","doi-asserted-by":"crossref","first-page":"941","DOI":"10.1128\/JCM.21.6.941-946.1985","volume":"21","year":"1985","journal-title":"J Clin Microbiol"},{"key":"p_49","first-page":"584","volume":"6","year":"1987","journal-title":"Clin Microbiol"},{"key":"p_54","doi-asserted-by":"publisher","DOI":"10.1128\/AAC.26.1.94"},{"key":"p_59","doi-asserted-by":"publisher","DOI":"10.1128\/AAC.29.3.386"},{"key":"p_63","first-page":"287","volume":"62","year":"1987","journal-title":"Kekkaku"},{"key":"p_75","doi-asserted-by":"publisher","DOI":"10.1093\/jac\/21.4.501"},{"key":"p_79","doi-asserted-by":"publisher","DOI":"10.1016\/0769-2609(88)90008-7"},{"key":"p_97","doi-asserted-by":"crossref","first-page":"1217","DOI":"10.1164\/ajrccm\/137.5.1217","volume":"137","year":"1988","journal-title":"Respir Dis"}],"container-title":["American Review of Respiratory Disease"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/academic.oup.com\/ajrccm\/article-pdf\/140\/4\/987\/67650926\/ajrccm_140_4_987.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/academic.oup.com\/ajrccm\/article-pdf\/140\/4\/987\/67650926\/ajrccm_140_4_987.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,3,30]],"date-time":"2026-03-30T10:02:36Z","timestamp":1774864956000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/ajrccm\/article\/140\/4\/987\/8559115"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1989,10,1]]},"references-count":14,"journal-issue":{"issue":"4","published-online":{"date-parts":[[1989,10,1]]},"published-print":{"date-parts":[[1989,10,1]]}},"URL":"https:\/\/doi.org\/10.1164\/ajrccm\/140.4.987","relation":{},"ISSN":["0003-0805"],"issn-type":[{"value":"0003-0805","type":"print"}],"subject":[],"published-other":{"date-parts":[[1989,10]]},"published":{"date-parts":[[1989,10,1]]}}}
