Objective: To study the roles of gasmid mite and chigger mite in the transmission of hemorrhagic fever with renal syndrome virus (HFRSV).
Methods: Natural gasmid mite, the first generation gasmid mite, chigger mite larvas from rats, free chigger mite larva and nymph were collected and their cells were cultured to study the role of transmission HFRSV.
Results: HFRSV was detected from mite cells after cultured for 15 and 20 days. The number of HFRSV and fluorescence intensity detected from the fhird and fourth generation gasmid mite and chigger mite nymph was much more than those from the first, second generation and chigger mite larva.
Conclusion: Gasmid mite and chigger mite had an important role to play on HFRSV transmission in keeping the natural cycles.
