Abstract
The Ebola virus (EBOV) causes a highly virulent and deadly disease. The 2014 Ebola outbreak in West Africa was the largest in history. The rapid spread highlighted the need for a quick and accurate diagnostic method that can be employed in resource-limited conditions. In this study, we developed a probe that can be used as an internal positive control, coupled with a reverse transcription loop-mediated isothermal amplification (RT-LAMP) assay to accurately detect EBOV. This RT-LAMP assay is a simple one-step reaction performed at a constant temperature, and the results can be visualized by a colorimetric change from violet to sky blue. Our assay enabled detection of 10 copies of synthetic EBOV RNA within 1 h. Compared to traditional RT-qPCR, RT-LAMP requires no sophisticated equipment, the results are easier to interpret, and they can be obtained in less time. These features make RT-LAMP an ideal method for detection of EBOV in low-resource settings.
