| genomic sequence and phylogenetic analysis of culex flavivirus, an insect-specific flavivirus, isolated from culex pipiens (diptera: culicidae) in iowa. | adult mosquitoes (diptera: culicidae) were collected in 2007 and tested for specific viruses, including west nile virus, as part of the ongoing arbovirus surveillance efforts in the state of iowa. a subset of these mosquitoes (6,061 individuals in 340 pools) was further tested by reverse transcription-polymerase chain reaction (rt-pcr) using flavivirus universal primers. of the 211 pools of culex pipiens (l.) tested, 50 were positive. one of 51 pools of culex tarsalis coquillet was also positive ... | 2009 | 19645300 |
| culex flavivirus and west nile virus in culex quinquefasciatus populations in the southeastern united states. | little is known of the interactions between insect-only flaviviruses and other arboviruses in their mosquito hosts, or the potential public health significance of these associations. the specific aims of this study were to describe the geographic distribution, prevalence, and seasonal infection rates of culex flavivirus (cxfv) and west nile virus (wnv) in culex quinquefasciatus say in the southeastern united states, investigate the potential association between cxfv and wnv prevalence in cx. qui ... | 2012 | 22308785 |
