| the role of deer as a possible reservoir host of potosi virus, a newly recognized arbovirus in the united states. | potosi (pot) virus (bunyaviridae) was isolated from aedes albopictus, an introduced asian mosquito species, collected at a used tire yard in potosi, missouri (usa), in august and september, 1989. in september, 1990, small animals were trapped at the tire yard and six cattle were sampled at an adjacent farm; in november 1990 and 1991, blood samples were collected with filter paper strips from 364 hunter-killed, white-tailed deer (odocoileus virginianus) in the region to determine the possible res ... | 1996 | 8827670 |
| prevalence of granulocytic ehrlichia infection among white-tailed deer in wisconsin. | human granulocytic ehrlichiosis (hge) is caused by an agent that is nearly indistinguishable from the veterinary pathogens ehrlichia equi and ehrlichia phagocytophila. the deer tick, ixodes scapularis, is a vector of the hge agent, and the white-tailed deer is the primary host for adult ixodes ticks. we assessed the distribution of granulocytic ehrlichia infection among deer living within (wisconsin) and outside (western and southern iowa) the geographic range of l. scapularis. whole-blood sampl ... | 1997 | 9163463 |
| ehrlichia chaffeensis antibodies in white-tailed deer, iowa, 1994 and 1996. | surveillance of 2,277 white-tailed deer for antibodies against ehrlichia chaffeensis in iowa showed seropositivity rates of 12.5% in 1994 and 13.9% in 1996. from 1994 to 1996, the estimated number of seropositive deer increased to 54,701 (28%). the increasing deer population and expanding tick distribution may increase risk for human monocytic ehrlichiosis. | 2000 | 10905976 |
| seroprevalence of neospora caninum and toxoplasma gondii antibodies in white-tailed deer (odocoileus virginianus) from iowa and minnesota using four serologic tests. | the white-tailed deer (odocoileus virginianus) is considered one of the most important wildlife reservoirs of neospora caninum and toxoplasma gondii in the us. sera from white-tailed deer from minnesota and iowa were tested for antibodies to n. caninum by four serologic tests including the indirect fluorescent antibody (ifa) test (cut-off 1:25), neospora caninum agglutination test (cut-off 1:25), an enzyme-linked immunoabsorbent assay, and western blot (wb). sera were also tested for antibodies ... | 2009 | 19285809 |
| development and performance evaluation of a streamlined method for nucleic acid purification, denaturation, and multiplex detection of bluetongue virus and epizootic hemorrhagic disease virus. | bluetongue virus (btv) and epizootic hemorrhagic disease virus (ehdv) possess similar structural and molecular features, are transmitted by biting midges (genus culicoides), and cause similar diseases in some susceptible ruminants. generally, btv causes subclinical disease in cattle, characterized by a prolonged viremia. ehdv-associated disease in cattle is less prominent; however, it has emerged as a major economic threat to the white-tailed deer (odocoileus virginianus) industry in many areas ... | 2013 | 24091683 |
| characterization of epizootic hemorrhagic disease virus from a bovine with clinical disease with high nucleotide sequence identity to white-tailed deer isolates. | epizootic hemorrhagic disease virus (ehdv) was isolated from a pregnant cow in indiana, usa, exhibiting excessive salivation, pyrexia and abortion. vp2, vp5, and vp7 sequences of the isolated bovine ehdv showed 97.7, 97.4, and 97.9 % identity to a serotype 2 reference virus. bovine ehdv was closely related (>99.9 %) to white tailed deer (wtd) ehdv collected from iowa in 2013 and showed less than 2.1 % divergence from ehdv collected from wtd across the usa in 2013. the high degree of sequence ide ... | 2014 | 24852073 |
| review of the 2012 epizootic hemorrhagic disease outbreak in domestic ruminants in the united states. | an unusually large number of cases of epizootic hemorrhagic disease (ehd) were observed in united states cattle and white-tailed deer in the summer and fall of 2012. usda aphis veterinary services area offices were asked to report on foreign animal disease investigations and state diagnostic laboratory submissions which resulted in a diagnosis of ehd based on positive pcr results. ehd was reported in the following species: cattle (129 herds), captive white-tailed deer (65 herds), bison (8 herds) ... | 2015 | 26244773 |
| serosurveillance for anaplasma phagocytophilum antibodies in white-tailed deer (odocoileus virginianus) in iowa, usa. | cases of human granulocytic anaplasmosis have increased in number and are being identified in new geographic areas since its discovery in 1994. white-tailed deer (wtd) become infected with the causative agent, anaplasma phagocytophilum, and serve as natural sentinels for this organism. in order to determine if a. phagocytophilum is present in the state of iowa, sera collected from 628 wtd in 2004 from 13 sites and from 282 wtd in 1999 from a single, common site were tested by enzyme-linked immun ... | 2006 | 16989567 |
| west nile virus serosurveillance in iowa white-tailed deer (1999-2003). | sera from white-tailed deer (odocoileus virginianus) were collected in iowa during the winter months (1999-2003), 2 years before and after west nile virus (wnv) was first reported in iowa (2001), and were analyzed for antibodies to wnv. samples from 1999 to 2001 were antibody negative by blocking enzyme-linked immunosorbent assay (belisa) and plaque reduction neutralization test (prnt(90)). prevalence derived from belisa (2002, 12.7%; 2003, 11.2%) and wnv prnt(90) (2002, 7.9%; 2003, 8.5%) assays ... | 2005 | 16354809 |
| parelaphostrongylus tenuis (nematoda) in white-tailed deer (odocoileus virginianus) in central iowa. | heads of hunter-killed white-tailed deer (odocoileus virginianus) were obtained from a tri-county area in central iowa in december 1991 and examined for the presence of parelaphostrongylus tenuis (dougherty, 1945). adults of p. tenuis were found in 45% of 42 deer heads; the mean intensity of infection was 3.6 (range: 1-16). prevalence of infection was significantly greater in female deer > 13 mo of age in comparison to males of similar age (54 vs. 17%). mean intensity of infection was significan ... | 1993 | 8437050 |
| the first 10 years (2006-15) of epizootic hemorrhagic disease virus serotype 6 in the usa. | epizootic hemorrhagic disease virus (ehdv) is a culicoides biting midge-transmitted orbivirus (family reoviridae) of wild and domestic ruminants and is an important pathogen of white-tailed deer (odocoileus virginianus). historically, only two serotypes, ehdv-1 and ehdv-2, have been known to be endemic in the us. however, in 2006, an exotic serotype (ehdv-6) was first detected in the united states by a long-term passive surveillance system for ehdv and bluetongue viruses. here we report ehdv-6 d ... | 2017 | 28657859 |
