| serologic evidence of exposure of wild mammals to flaviviruses in the central and eastern united states. | serosurveys were conducted to obtain flavivirus and west nile virus (wnv) seroprevalence data from mammals. sera from 513 small- and medium-sized mammals collected during late summer and fall 2003 from colorado, louisiana, new york, ohio, and pennsylvania were screened for flavivirus-specific antibodies. sera samples containing antibody to flaviviruses were screened for wnv-specific antibodies by epitope-blocking enzyme-linked immunosorbent assays and confirmed with plaque reduction neutralizati ... | 2005 | 15891139 |
| serologic evidence of west nile virus infection in free-ranging mammals, slidell, louisiana, 2002. | after an outbreak of west nile virus (wnv) infections in slidell, louisiana, in 2002, we detected neutralizing antibodies to wnv in 13 of 120 mammals, representing five of six species sampled. seroprevalence was measured in opossum, didelphis virginiana (75%, n = 8), raccoons, procyon lotor (60%, n = 5), black rats, rattus rattus (6%, n = 36), hispid cotton rats, sigmodon hispidus (4%, n = 24), and eastern gray squirrels, sciurus carolinensis (2%, n = 43). | 2005 | 16187899 |
| human bloodfeeding by the recently introduced mosquito, aedes japonicus japonicus, and public health implications. | knowledge of the host-feeding behavior and extent of interactions with human hosts are important in evaluating the role and vector potential of invasive mosquitoes in transmission of native arboviruses. we collected blood-engorged females of the recently established exotic species aedes japonicus japonicus from sites in new jersey during 2000 to 2007 and identified the sources of vertebrate blood meals by sequencing portions of the cytochrome b gene of mitochondrial dna. over 1/3 (36%, n = 36) o ... | 2009 | 19653507 |
| west nile virus isolated from a virginia opossum (didelphis virginiana) in northwestern missouri, usa, 2012. | we describe the isolation of west nile virus (wnv; flaviviridae, flavivirus) from blood of a virginia opossum (didelphis virginiana) collected in northwestern missouri, usa in august 2012. sequencing determined that the virus was related to lineage 1a wnv02 strains. we discuss the role of wildlife in wnv disease epidemiology. | 2014 | 25098303 |
| fatal west nile virus infection in a virginia opossum (didelphis virginiana) with pulmonary lepidic-predominant adenocarcinoma. | a fatal case of west nile virus (wnv) infection was diagnosed based on histopathologic findings and the presence of wnv rna by reverse transcription pcr in the affected organs in a virginia opossum (didelphis virginiana) in quebec, canada in 2017. disease caused by wnv has not been described in a marsupial species. | 2019 | 31008678 |
| west nile virus associations in wild mammals: an update. | although west nile virus (wnv) is generally thought to circulate among mosquitoes and birds, several historic and recent works providing evidence of wnv activity in wild mammals have been published. indeed, a previous review tabulated evidence of wnv exposure in at least 100 mammalian species. herein, we provide an update on wnv activity in wild and select other mammals that have been reported since the last major review article on this subject was published in early 2013. of interest, new speci ... | 2019 | 31117189 |
| antibodies to west nile virus in raccoons and other wild peridomestic mammals in iowa. | surveillance for evidence of west nile virus (wnv) infection in small- and medium-sized wild mammals was conducted in iowa, usa, from may 2005 to june 2007. sera were collected from 325 mammals belonging to nine species and tested for antibodies to wnv and other flaviviruses by epitope-blocking enzyme-linked immunosorbent assay (elisa). all sera that had antibodies to flaviviruses by blocking elisa were further examined by plaque reduction neutralization test (prnt). thirteen mammals were seropo ... | 2009 | 19901390 |
