In comparison, mice treated twice daily with oral ciprofloxacin or doxycycline (50 mg\/kg) or phosphate-buffered saline (PBS) lost 15 to 20% body weight and exhibited ruffled fur, arched backs, and dehydration. Mice were culled at day 14 postchallenge. The weights and bacterial burdens of organs were determined. Mice treated with CFI exhibited reduced splenomegaly and reduced bacterial numbers in the lungs and spleen compared to mice treated with oral ciprofloxacin or doxycycline. When a single dose of CFI was administered, it provided better protection against body weight loss than 7 days of treatment with oral doxycycline, the current antibiotic of choice to treat Q fever. These data suggest that CFI has potential as a superior antibiotic to treat Q fever.\n                  <\/jats:p>","DOI":"10.1128\/aac.03443-14","type":"journal-article","created":{"date-parts":[[2014,7,8]],"date-time":"2014-07-08T00:16:33Z","timestamp":1404778593000},"page":"5510-5518","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":28,"title":["Efficacy of Liposome-Encapsulated Ciprofloxacin in a Murine Model of Q Fever"],"prefix":"10.1128","volume":"58","author":[{"given":"I.
