摘要: Getah virus (GETV) is a mosquito-borne alphavirus that is considered to be an emerging pathogen. To date, reverse transcription loop-mediated isothermal amplification (RT-LAMP) has not been used to detect GETV. Therefore, we describe a novel, fast, and sensitive LAMP method to detect GETV. Amplification of GETV RNA can be obtained within 50 min at 65 degrees C. This RT-LAMP method was verified to be highly specific for GETV, with no cross detection of other viruses. The assay was 10(3) and 10(1) times more sensitive than RT-PCR and RT-qPCR, respectively, for the detection of GETV RNA. This novel RT-LAMP method provides a practical and economical alternative for detecting GETV in mosquitoes and serum samples that can be used even in the field.
