Treatment with gentamicin in positively charged liposomes produced a protective effect when it was administered 1 day after lethal challenge (70% of protection). On the other hand, the use of free gentamicin or in liposomes with a negative net charge did not produce a protective effect. Moreover, the results reported here also indicated that cationic liposomes themselves had a therapeutic effect on the course of the infection (up to 50% of protection). In conclusion, we observed that cationic liposomal encapsulation of gentamicin resulted in an enhancement of the therapeutic activity of free gentamicin in this mouse model of acute infection.<\/jats:p>","DOI":"10.1159\/000239563","type":"journal-article","created":{"date-parts":[[2009,9,11]],"date-time":"2009-09-11T09:12:33Z","timestamp":1252660353000},"page":"204-210","source":"Crossref","is-referenced-by-count":18,"title":["Protective Effect of Liposomal Gentamicin against Systemic Acute Murine Brucellosis"],"prefix":"10.1159","author":[{"given":"Ana l.","family":"Vitas","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ram\u00f3n","family":"D\u00edaz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carlos","family":"Gamazo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2009,9,11]]},"container-title":["Chemotherapy"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/239563","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000239563","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T15:46:59Z","timestamp":1777477619000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000239563"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,9,11]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000239563","archive":["Portico"],"relation":{},"ISSN":["0009-3157","1421-9794"],"issn-type":[{"value":"0009-3157","type":"print"},{"value":"1421-9794","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,9,11]]}}}
