| evidence for a population expansion in the west nile virus vector culex tarsalis. | population genetic structure of the west nile virus vector culex tarsalis was investigated in 5 states in the western united states using 5 microsatellite loci and a fragment of the mitochondrial reduced form of nicotinamide adenine dinucleotide dehydrogenase 4 (nd4) gene. nd4 sequence analysis revealed a lack of isolation by distance, panmixia across all populations, an excess of rare haplotypes, and a star-like phylogeny. microsatellites revealed moderate genetic differentiation and isolation ... | 2007 | 17339636 |
| west nile virus neuroinvasive disease incidence in the united states, 2002-2006. | as the geographic range of reported human west nile virus (wnv) disease has expanded across the united states, seasonal transmission and outbreaks have persisted over several years in many areas of the country. west nile virus neuroinvasive disease (wnnd) case reports from 2002 to 2006 were reviewed to determine which areas of the country have the highest reported cumulative incidence and whether those areas have had consistently high annual incidence. during the 5-year period examined, 9632 cas ... | 2008 | 18237264 |
