Although colistin has been used as a treatment of last resort, there is concern regarding its potential for toxicity and the emergence of resistance. The mechanism of action of colistin, however, raises the possibility of synergy with compounds that are normally inactive against Gram-negative organisms by virtue of the impermeability of the bacterial outer membrane. This study evaluated the effect of colistin combined with vancomycin on 5 previously characterized epidemic strains and 34 MDRAB clinical isolates by using time-kill assay, microdilution, and Etest methods. For all the isolates, significant synergy was demonstrated by at least one method, with reductions in the MIC of vancomycin from &gt;256 \u03bcg\/ml to \u226448 \u03bcg\/ml for all strains after exposure to 0.5 \u03bcg\/ml colistin. This raises the possibility of the clinical use of this combination for infections due to MDRAB, with the potential for doses lower than those currently used.\n                  <\/jats:p>","DOI":"10.1128\/aac.00922-10","type":"journal-article","created":{"date-parts":[[2010,9,28]],"date-time":"2010-09-28T00:44:26Z","timestamp":1285634666000},"page":"5316-5322","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":174,"title":["Potent Synergy and Sustained Bactericidal Activity of a Vancomycin-Colistin Combination versus Multidrug-Resistant Strains of\n                    <i>Acinetobacter baumannii<\/i>"],"prefix":"10.1128","volume":"54","author":[{"given":"N.
