phylogenetic analysis of buggy creek virus: evidence for multiple clades in the western great plains, united states of america.we present the first detailed phylogenetic analysis of buggy creek virus (bcrv), a poorly known alphavirus with transmission cycles involving a cimicid swallow bug (oeciacus vicarius) vector and cliff swallows (petrochelidon pyrrhonota) and house sparrows (passer domesticus) as the principal avian hosts. nucleotide sequences of a 2,075-bp viral envelope glycoprotein-coding region, covering the entire pe2 gene, were determined for 33 bcrv isolates taken from swallow bugs at cliff swallow colonies ...200616936062
ecological correlates of buggy creek virus infection in oeciacus vicarius, southwestern nebraska, 2004.buggy creek virus (family togaviridae, genus alphavirus, bcrv) is an alphavirus within the western equine encephalitis virus complex whose primary vector is the swallow bug, oeciacus vicarius horvath (hemiptera: cimicidae), an ectoparasite of the colonially nesting cliff swallow, petrochelidon pyrrhonota, that is also a frequent host for the virus. we investigated ecological correlates of bcrv infection in 100-bug pools at 14 different swallow colony sites in southwestern nebraska from summer 20 ...200717294919
phylogeographical structure and evolutionary history of two buggy creek virus lineages in the western great plains of north america.buggy creek virus (bcrv) is an unusual arbovirus within the western equine encephalitis complex of alphaviruses. associated with cimicid swallow bugs (oeciacus vicarius) as its vector and the cliff swallow (petrochelidon pyrrhonota) and house sparrow (passer domesticus) as its amplifying hosts, this virus is found primarily in the western great plains of north america at spatially discrete swallow nesting colonies. for 342 isolates collected in oklahoma, nebraska, colorado and north dakota, from ...200818753221
west nile virus activity - united states, 2009.west nile virus (wnv) was first detected in the western hemisphere in 1999 in new york city and has since caused seasonal epidemics of febrile illness and neurologic disease across the united states, where it is now the leading cause of arboviral encephalitis. this report updates a previous report and summarizes wnv activity in the united states reported to cdc in 2009. a total of 38 states and the district of columbia (dc) reported 720 cases of wnv disease. of these, 33 states and dc reported 3 ...201020592686
west nile virus disease and other arboviral diseases --- united states, 2010.arthropod-borne viruses (arboviruses) are transmitted to humans primarily through the bites of infected mosquitoes and ticks. since west nile virus (wnv) was first detected in the western hemisphere in 1999, it has become the leading cause of neuroinvasive arboviral disease in the united states. however, several other arboviruses continue to cause sporadic cases and seasonal outbreaks of neuroinvasive disease (i.e., meningitis, encephalitis, or acute flaccid paralysis). this report summarizes su ...201121814163
