| eastern equine encephalitis transmission to emus (dromaius novaehollandiae) in volusia county, florida: 1992 through 1994. | from may 1992 through october 1994, sera were collected from 204 domestic emus (dromaius novaehollandiae) at a ranch in volusia county, fl, and tested for antibody evidence of arboviral infection. hemagglutination-inhibition (hi) and neutralizing (nt) antibodies to eastern equine encephalitis (eee) virus were identified in sera collected during each year. in addition, hi and nt antibodies to st. louis encephalitis virus were detected in 3 naturally infected emus. isolations of eee virus were mad ... | 1996 | 8887222 |
| arbovirus surveillance in south carolina, 1996-98. | arboviruses isolated and identified from mosquitoes in south carolina (usa) are described, including new state records for eastern equine encephalitis virus (eee), st. louis encephalitis virus (sle), flanders virus, tensaw virus (ten), and a variant of jamestown canyon virus (jc). mosquitoes were collected at 52 locations in 30 of 46 south carolina counties beginning in june 1996, and ending in october 1998, and tested for arboviruses. of 1,329 mosquito pools tested by virus isolation (85,806 mo ... | 2001 | 11345423 |
| winter biology of wetland mosquitoes at a focus of eastern equine encephalomyelitis virus transmission in alabama, usa. | at temperate latitudes, vectors and pathogens must possess biological mechanisms for coping with cold temperatures and surviving from one transmission season to the next. mosquitoes that overwinter in the adult stage have been proposed as winter maintenance hosts for certain arboviruses. in the cases of west nile virus (family flaviviridae, genus flavivirus) and st. louis encephalitis virus (family flaviviridae, genus flavivirus), discovery of infected overwintering females lends support to this ... | 2011 | 21936314 |
| nesting bird "host funnel" increases mosquito-bird contact rate. | increases in vector-host contact rates can enhance arbovirus transmission intensity. we investigated weekly fluctuations in contact rates between mosquitoes and nesting birds using the recently described nest mosquito trap (nmt). the number of mosquitoes per nestling increased from < 1 mosquito per trap night to 36.2 in the final 2 wk of the nesting season. our evidence suggests the coincidence of the end of the avian nesting season and increasing mosquito abundances may have caused a "host funn ... | 0 | 23540137 |
| host preference of the arbovirus vector culex erraticus (diptera: culicidae) at sonso lake, cauca valley department, colombia. | culex erraticus (dyar & knab) is a competent vector of eastern equine encephalitis virus and subtype ic venezuelan equine encephalitis virus, and both st. louis encephalitis virus and west nile virus have been isolated from field-collected specimens. previous bloodmeal analysis studies have shown this species to be a generalist, feeding on a variety of mammals, birds, reptiles, and amphibians. this behavior can bridge arboviral transmission across different vertebrate groups. our study examined ... | 2012 | 23025191 |
