These results demonstrate that North American Culex mosquito species are competent vectors of African and European L2 WNV and that emergence of L2 WNV is unlikely to be hindered by poor competence of North American vectors. quinquefasciatus compared with other L2 WNV strains. These brands are among the most recognized and respected names in the industry and each has a proven record of success in addition to a large and loyal global customer base. In addition, a South African L2 WNV strain (SA89) displayed a significantly shorter extrinsic incubation period in Cx. Aviagen Broiler Breeders supplies day-old grandparent and parent stock chicks to customers in 130 countries worldwide under the Arbor Acres, Indian River, and Ross brand names. pipiens compared with other L2 WNV strains. An L2 WNV strain (NS10) isolated during the Greek outbreak in 2010 exhibited a reduced capacity to infect Cx. Both mosquito species were highly competent for each of the L2 WNV strains assessed, but variation in infection, dissemination, and transmission was observed. We address the vector competence of North American Culex pipiens and Culex quinquefasciatus for L2 WNV. Assessing the vector competence of North American Culex mosquitoes for L2 WNV will be critical for predicting the potential for L2 WNV emergence in North America. 1 family: Volume 20: Partial, Enter from Volume 19 1 family: Volume 21: Partial, Enter from Volume 19 1 family: Volume 22: Magnoliophyta: Alismatidae Arecidae, Commelinidae (in Part), and Zingiberidae 30 families: Volume 23: Magnoliophyta: Commelinidae (in part): Cyperaceae 1 family: Volume 26: Magnoliophyta: Liliidae: Liliales and Orchidales. The vector competence of mosquitoes within the Culex genus for WNV is well established for L1 WNV but less extensively studied for L2 WNV. ESL 03310 Woodriff, Ray Stone, Ronald W. The spread of L2 WNV throughout and beyond Europe depends, in part, on availability of competent vectors. lineage came from the late Pleistocene of North America, and the collared.

Although L1 WNV is globally distributed, including North America, L2 WNV only recently emerged out of sub-Saharan Africa into Europe and Russia. Lineage 1 (L1) and lineage 2 (L2) encompass all WNV isolates associated with human and veterinary disease cases. West Nile virus (WNV) is a mosquito-borne flavivirus that is phylogenetically separated into distinct lineages.
