Identification of New PCR Targets and its Validation for Development of Nucleic Acid-based Detection Assay for Melioidosis

AbstractBurkholderia pseudomallei the gram negative, soil saprophyte is the causative agent of melioidosis in human and animals. Development of rapid, sensitive, species specific and cost effective molecular assays are needed for detection of B. pseudomallei from clinical and environmental samples and to differentiate it from other closely related bacterial species. In this study, insilico approach was used to identify new species specific gene targets for molecular diagnosis of B. pseudomallei. The identified targets were then analyzed by SYBR Green real time PCR assay for their specificity, sensitivity and presence across different Indian clinical and soil isolates of B. pseudomallei. Out of the three targets studied SYBR Green real time PCR assay targeting bpss0091 gene of B. pseudomallei was found 100% specific, having detection limit of 12.3fg/µl DNA. The bpss0091 gene target was present in all clinical and soil isolates of B. pseudomallei tested thus suggesting bpss0091 gene based SYBR Green real time PCR assay will be useful for detection of B. pseudomallei in different geographical regions.
