| comparison of mosquito trapping method efficacy for west nile virus surveillance in new mexico. | as part of the west nile virus surveillance program for the state of new mexico, 13 sites along the rio grande river were sampled for mosquitoes during spring and summer 2003. we evaluated 3 different trapping procedures for their effectiveness at capturing selected species of mosquitoes. the 3 methods used were a dry ice-baited centers for disease control and prevention (cdc) light trap set 1.5 m above the ground (standard method), a cdc light trap suspended within the forest canopy, and a grav ... | 2006 | 17019770 |
| 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 |
| urban habitat evaluation for west nile virus surveillance in mosquitoes in albuquerque, new mexico. | as part of an ongoing mosquito surveillance program, 27 sites in the greater metropolitan albuquerque area (bernalillo county, new mexico) were trapped from may through september 2004. each site was sampled for 1 night weekly, using a standard co2-baited centers for disease control and prevention light trap and a gravid trap. captured mosquitoes were catalogued by location, species, and date, and selected pools were tested for west nile virus (wnv) by reverse transcription-polymerase chain react ... | 2007 | 17847847 |
| 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 |
| persistent neuropsychological impairment associated with west nile virus infection. | west nile virus infection can result in prolonged subjective complaints of cognitive and functional decline even in the absence of a neuroinvasive form of infection. persistent cognitive and functional complaints could be a result of general somatic symptoms, emotional distress, or residual central nervous system damage or dysfunction. most studies of cognition in postacute west nile virus infection rely on self-report. this descriptive study aimed to document cognitive deficits in a sample of t ... | 2009 | 19513920 |
| potential vectors of west nile virus in a semiarid environment: doña ana county, new mexico. | the potential vectors of west nile virus (family flaviviridae, genus flavivirus, wnv) in doña ana county, nm, were determined during 2004 and 2005. trapping was conducted using centers for disease control and prevention miniature light-traps baited with dry ice, and gravid traps baited with a hay infusion. in addition, sentinel chickens were housed at four of the trapping locations to monitor wnv epizootic transmission. in total, 5,576 pools consisting of 115,797 female mosquitoes were tested fo ... | 2009 | 19960700 |
| 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 ... | 2011 | 21814163 |
| internally deleted wnv genomes isolated from exotic birds in new mexico: function in cells, mosquitoes, and mice. | most rna viruses exist in their hosts as a heterogeneous population of related variants. due to error prone replication, mutants are constantly generated which may differ in individual fitness from the population as a whole. here we characterize three wnv isolates that contain, along with full-length genomes, mutants with large internal deletions to structural and nonstructural protein-coding regions. the isolates were all obtained from lorikeets that died from wnv at the rio grande zoo in albuq ... | 2012 | 22365325 |
| evaluation of seasonal feeding patterns of west nile virus vectors in bernalillo county, new mexico, united states: implications for disease transmission. | many mosquito species take bloodmeals predominantly from either birds or mammals. other mosquito species are less host-specific and feed readily on both. furthermore, some species tend to alter their feeding patterns over the course of the year; early in the mosquito season such species may feed primarily on a particular host type, and subsequently take an increasingly larger proportion of their bloodmeals from an alternative host type as the season progresses. we have examined the feeding patte ... | 0 | 24605477 |
| fatal hemophagocytic lymphohistiocytosis associated with locally acquired dengue virus infection - new mexico and texas, 2012. | dengue is caused by infection with any of four mosquito-transmitted dengue viruses (denv-1-4) and is characterized by fever, headache, myalgia, and leukopenia. hemophagocytic lymphohistiocytosis (hlh) is a potentially fatal hyperinflammatory syndrome that can be familial or acquired, and is characterized by persistent fever, pancytopenia, hepatosplenomegaly, and increased serum ferritin. acquired hlh is most frequently associated with epstein barr virus infection but also has been associated wit ... | 2014 | 24452132 |
