In a prospective study of 123 healthy adults competing in a mud-exposing endurance challenge in the melioidosis-endemic tropical north of the Northern Territory of Australia, there were no asymptomatic seroconversions to Burkholderia pseudomallei using indirect hemagglutination assay. However, one competitor developed melioidosis attributable to infection acquired during the event.
