Exposure to Burkholderia pseudomallei induces cell-mediated immunity in healthy individuals

Abstract

Melioidosis is an emerging tropical infection caused by the intracellular bacterium Burkholderia pseudomallei, and is associated with high mortality rates. Previous studies investigating the prevalence of melioidosis have based conclusions on serological evidence. However, cell-mediated immunity is more relevant for protection against an intracellular pathogen such as B. pseudomallei. This is the first demonstration that exposure to B. pseudomallei may lead to the formation of specific antibodies and the development of cell-mediated immunity in a healthy individual. © 2004 Copyright by the European Society of Clinical Microbiology and Infectious Diseases.
