Abstract |
Severe fever with thrombocytopenia syndrome (SFTS) is being
reported annually in South Korea since its first detection
there in 2010. The causal agent is a negative-strand RNA
virus 80–100 nm in diameter. It causes fever, thrombocytopenia,
leukocytopenia, gastrointestinal symptoms, and neural
symptoms. The mortality rate of SFTS was 32.6% among 172
cases reported from 2012 to 2015 in South Korea. Thus, is
necessary to develop an effective diagnostic method that selectively
identifies the isolates circulating in South Korea. The
real-time reverse transcription loop-mediated isothermal amplification
(RT-LAMP) assay is a simple, rapid, and sensitive
approach for molecular diagnosis. Here, we designed novel
primers for this assay and found that the technique had very
high specificity, sensitivity, and efficiency. This real-time RTLAMP
approach using the novel primers developed herein
can be applied for early diagnosis of SFTSV strains in South
Korea to reduce the mortality rate of SFTS. |
