Abstract
Melioidosis is caused by Burkholderia pseudomallei. Direct molecular detection from unamplified blood remains insensitive. Three different extraction methods-QIAamp UCP Pathogen Mini Kit, High Pure PCR template and MagNA Pure Pathogen Universal-were trialled using spiked human ethylenediaminetetraacetic acid blood. A type III secretion system 1 (TTSS-1) polymerase chain reaction was used for detection. The QIAamp UCP Pathogen Mini Kit performed best, with a limit of detection of 1.5×102cfu/ml. It is planned to use the QIAamp UCP Pathogen Mini Kit to do a larger study on blood collected from patients with melioidosis.
