Activity of tigecycline in the treatment of acute Burkholderia pseudomallei infection in a murine model

Int J Antimicrob Agents. 2006 Nov;28(5):460-4. doi: 10.1016/j.ijantimicag.2006.07.022.

Abstract

Burkholderia pseudomallei is the causative agent of melioidosis. Standard therapy includes ceftazidime alone or in combination with co-trimoxazole. Tigecycline, a novel agent, has displayed activity against B. pseudomallei. We evaluated the in vivo efficacy of tigecycline using a murine model of melioidosis. Mice were infected with either a high or low virulence B. pseudomallei isolate followed by administration of antibiotics alone or in combination (tigecycline, ceftazidime, tigecycline plus ceftazidime) for 7 days. Bacterial loads were assessed up to 7 days and survival was determined up to 7 days post infection. Tigecycline in combination with ceftazidime was the most effective and conferred the lowest mortality, suggesting the use of this new agent in B. pseudomallei infection.
