Abstract

Abstract

The simian parasite is now the commonest cause of malaria in Malaysia and can rapidly cause severe and fatal malaria. However, microscopic misdiagnosis of species is common, rapid antigen detection tests remain insufficiently sensitive and confirmation of requires polymerase chain reaction (PCR). Thus available point-of-care diagnostic tests are inadequate. This study reports the development of a simple, sensitive, colorimetric, high-throughput loop-mediated isothermal amplification assay (HtLAMP) diagnostic test using novel primers for the detection of This assay is able to detect 0.2 parasites/μL, and compared with PCR has a sensitivity of 96% for the detection of , making it a potentially field-applicable point-of-care diagnostic tool.
