Abstract
Purpose of review: Burkholderia pseudomallei, the causative agent of melioidosis and a potential biological weapon, is still unfamiliar in some areas where sporadic cases are being reported among travelers. This review highlights findings in 2002-2003 and is an extension of a recent review by Dance [1 *]. Recent findings: The allele profiles of B. pseudomallei are distinguishable from avirulent Burkholderia thailandensis, but Burkholderia mallei is a clone of B. pseudomallei. Capsule and a type III protein secretion apparatus enable B. pseudomallei to survive intracellular killing and facilitate intercellular spread. A strong antibody response to infection is useful for monitoring disease activity. A mutant that is auxotrophic in the branched chain amino acid biosynthetic pathway has been found to be attenuated and protective. A new selective media is useful for isolation from contaminated specimens and the environment. Molecular techniques have been developed to distinguish B. pseudomallei from B. thailandensis and B. mallei as well as for serological diagnosis. Classification of the clinical manifestation is proposed to facilitate global communication, and will be useful to compare the efficacies of new regimens and adjunctive immunomodulatory therapies, such as granulocyte colony-stimulating factor and activated proton C for septicemic melioidosis. Summary: Study of pathogenesis and intracellular survival of B. pseudomallei is advancing and may lead to better methods of therapy and vaccine production. New antimicrobial agents and immunomodulators are being studied to shorten the duration of treatment in the acute and maintenance phases, reduce the high mortality rate in septicemic melioidosis, and prevent relapses. © 2004 Lippincott Williams & Wilkins.
