Half were isolated from patients with AIDS and the other half from patients without AIDS but with pulmonary disease. The MICs and MBCs were also determined in 7H12 broth for M. tuberculosis strains. The MIC results obtained with M. tuberculosis strains, and the serum peak levels in humans, were used as standards for interpretation of the MICs and MBCs of the rifamycins for M. avium. The bactericidal activity of all rifamycins for M. avium was substantially lower than for M. tuberculosis. The majority of M. avium strains was within the \u201csusceptible\u201d category, e.g., comparable to susceptible M. tuberculosis strains, when tested with CGP-7040 and RPT, and all of them were \u201cmoderately susceptible\u201d when tested with P-DEA. On the basis of in vitro bacteriostatic and bactericidal activity, it seems that three agents, RPT, P-DEA, and CGP-7040 have more potential than do RMP and RBT against M. avium disease.<\/jats:p>","DOI":"10.1164\/ajrccm\/141.3.626","type":"journal-article","created":{"date-parts":[[2011,8,3]],"date-time":"2011-08-03T15:36:16Z","timestamp":1312385776000},"page":"626-630","source":"Crossref","is-referenced-by-count":81,"title":["Bactericidal Activity\n                    <i>In Vitro<\/i>\n                    of Various Rifamycins against\n                    <i>Mycobacterium avium<\/i>\n                    and\n                    <i>Mycobacterium tuberculosis<\/i>"],"prefix":"10.1093","volume":"141","author":[{"given":"Leonid B.","family":"Heifets","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pamela J.","family":"Lindholm-Levy","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marcella A.","family":"Flory","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[1990,3,1]]},"reference":[{"key":"p_6","first-page":"251","volume":"57","year":"1976","journal-title":"Thbercle"},{"key":"p_11","doi-asserted-by":"crossref","first-page":"627","DOI":"10.1164\/arrd.1977.116.4.627","volume":"116","year":"1977","journal-title":"Am Rev Respir Dis"},{"key":"p_18","first-page":"367","volume":"123","year":"1981","journal-title":"Rev Respir Dis"},{"key":"p_26","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_31","first-page":"180","year":"1986","journal-title":"Amsterdam: Excerpta Medica"},{"key":"p_35","doi-asserted-by":"publisher","DOI":"10.1128\/AAC.31.1.117"},{"key":"p_39","doi-asserted-by":"publisher","DOI":"10.1093\/infdis\/156.3.510"},{"key":"p_43","doi-asserted-by":"publisher","DOI":"10.1128\/AAC.33.4.429"},{"key":"p_46","first-page":"773","volume":"1","year":"1977","journal-title":"Agents Chemother"},{"key":"p_51","doi-asserted-by":"publisher","DOI":"10.1128\/AAC.20.5.666"},{"key":"p_62","first-page":"530","volume":"6","year":"1987","journal-title":"Microbiol"},{"key":"p_67","doi-asserted-by":"publisher","DOI":"10.1128\/AAC.28.4.570"},{"key":"p_71","doi-asserted-by":"publisher","DOI":"10.1128\/AAC.32.8.1131"},{"key":"p_75","doi-asserted-by":"publisher","DOI":"10.1128\/AAC.30.6.927"},{"key":"p_80","first-page":"1000","year":"1985","journal-title":"Microbioloty"},{"key":"p_91","first-page":"177","volume":"68","year":"1987","journal-title":"Thbercle"},{"key":"p_94","first-page":"633","volume":"61","year":"1986","journal-title":"Kekkaku"},{"key":"p_124","first-page":"1","volume":"12","year":"1983","journal-title":"Chemother"},{"key":"p_137","doi-asserted-by":"publisher","DOI":"10.7164\/antibiotics.36.1502"},{"key":"p_150","first-page":"440","volume":"28","year":"1985","journal-title":"Chemother"},{"key":"p_153","first-page":"187","volume":"69","year":"1988","journal-title":"Thbercle"}],"container-title":["American Review of Respiratory Disease"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/academic.oup.com\/ajrccm\/article-pdf\/141\/3\/626\/67666131\/ajrccm_141_3_626.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/academic.oup.com\/ajrccm\/article-pdf\/141\/3\/626\/67666131\/ajrccm_141_3_626.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,3,31]],"date-time":"2026-03-31T04:15:17Z","timestamp":1774930517000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/ajrccm\/article\/141\/3\/626\/8558589"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1990,3,1]]},"references-count":21,"journal-issue":{"issue":"3","published-online":{"date-parts":[[1990,3,1]]},"published-print":{"date-parts":[[1990,3,1]]}},"URL":"https:\/\/doi.org\/10.1164\/ajrccm\/141.3.626","relation":{},"ISSN":["0003-0805"],"issn-type":[{"value":"0003-0805","type":"print"}],"subject":[],"published-other":{"date-parts":[[1990,3]]},"published":{"date-parts":[[1990,3,1]]}}}
