Abstract Environmental exposure to Burkholderia pseudomallei, the causative agent of melioidosis, remains poorly characterised due to the low sensitivity of conventional detection methods. Here, we develop CRISPR-BEEPs, a sensitive and resource-efficient CRISPR-based assay, and evaluate its performance against conventional culture-based plate inspection using double-qPCR as the reference standard. CRISPR-BEEPs demonstrated higher sensitivity (93.5% vs 19.4%) and high specificity (100% vs 98.0%).
