摘要: 
Culex flavivirus (CxFV), a member of the genus flavivirus, is a novel insectinsect-specific flavivirusesthat can be divided into two subtypes, the cytopathic Asia/U.S. and the noncytopathicAfrica/Caribbean/Latin American subtypes. The CxFV circulates in several Asian countries,and here we conducted the first study investigating CxFV in Taiwan. A total of 14,016mosquitoes were collected between 2010 and 2012 and 3.4% (6/179) of the pools wereCxFV-positive. The phylogenetic analyses indicate that the Taiwan isolates are closelyrelated to the Africa/Caribbean/Latin American subtype, but form an independent cluster. Inthe cytology experiments, the CxFV Taiwan isolate infected only mosquito cells and causedcell–cell fusion that might be associated with a unique glycine residue at position 117 withinthe envelope protein, which is shared with the cytopathic effect-causing Asia/US subtype.This study marks the first time the Africa/Caribbean/Latin American subtype of CxFV hasbeen identified in an Asian country and grouped into a novel cluster.
