Dynamic observation on proliferation of HFRSV in chigger mite
Abstract: In order to observe further dynamic changes on proliferation of HFRSV in Leptotrombidium Scutellare, the raised Leptotrombidium scutellare were ground and sterilized with an interval of 20-40 days, the filterate of each batch was inoculated separately into Vero - E6 cells, titres of HFRSV and HFRSV-RNA were detected. The results confirmed that HFRSV were positive in most batches of larva. The above results indicated that the Leptotrombidlum sutellare is a transmitting vector of HFRSV.
