A novel ready-to-use loop-mediated isothermal amplification (LAMP) method for detection of Burkholderia mallei and B. pseudomallei.
Article in BMC microbiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundGlanders and melioidosis are contagious zoonotic diseases caused by Burkholderia mallei and B. pseudomallei, respectively. Bacterial isolation and polymerase chain reaction (PCR) have been used to detect these bacteria in animals suspected of infection; however, both methods require skilled experimental techniques and expensive equipment. These obstacles make it difficult to diagnose B. mallei and B. pseudomallei infections in areas where reagents and equipment are difficult to procure. To solve this problem, we developed an easy and ready-to-use dried-format diagnostic tool based on loop-mediated isothermal amplification (LAMP) method.
resultsThe primer set targeting the internal transcribed spacer (ITS) region detected 10 genomic copies of B. mallei DNA and B. pseudomallei DNA using the conventional liquid LAMP method. This primer set did not detect any other Burkholderia species. Using this novel primer set, a dried-format in-house LAMP method with high sensitivity and specificity was developed. This method was used to test for the presence of B. mallei DNA in swabs collected from the nasal cavity and ulcerated skin of 19 B. mallei-infected horses and five uninfected horses and was compared with the real-time PCR method. These two tests showed 87.5% agreement for the positive samples and 100% agreement for the negative samples. This method detected all tested B. pseudomallei clinical isolates.
conclusionsWe established the first dry LAMP method for the detection of B. mallei and B. pseudomallei. This study provided a simple, rapid, cost-effective, and sensitive diagnostic tool for glanders and melioidosis.
