| parasites, diseases, and health status of sympatric populations of fallow deer and white-tailed deer in kentucky. | in august 1983, a study on parasites, diseases, and health status was conducted on sympatric populations of fallow deer (dama dama) and white-tailed deer (odocoileus virginianus) from land between the lakes, lyon and trigg counties, kentucky. five adult deer of each species were studied. white-tailed deer had antibodies to epizootic hemorrhagic disease (ehd) virus and leptospira interogans serovariety icterohemorrhagiae, and fallow deer had antibodies to bluetongue and ehd viruses. serologic tes ... | 1985 | 3999248 |
| diversity of piroplasms detected in blood-fed and questing ticks from several states in the united states. | piroplasms in the genera babesia, theileria, and cytauxzoon are tick-borne parasites that may be animal and human pathogens. most piroplasms with known life cycles are transmitted by ixodid ticks; however, for many species, the vector is unknown. this study was conducted to determine the prevalence and diversity of piroplasms in ticks from several us states. piroplasm-specific polymerase chain reaction (pcr) assays were used to test 1631 ticks from georgia (n=486), kentucky (n=103), pennsylvania ... | 2014 | 24709338 |
| ehrlichia ewingii infection in white-tailed deer (odocoileus virginianus). | two closely related zoonotic ehrlichiae, ehrlichia chaffeensis and e. ewingii, are transmitted by amblyomma americanum, the lone star tick. because white-tailed deer (odocoileus virginianus) are critical hosts for all mobile stages of a. americanum and are important vertebrate reservoirs of e. chaffeensis, we investigated whether deer may be infected with e. ewingii, a cause of granulocytotropic ehrlichiosis in humans and dogs. to test for e. ewingii infection, we used polymerase chain reaction ... | 2002 | 12095432 |
| new version of lstsim for computer simulation of amblyomma americanum (acari: ixodidae) population dynamics. | a previous version of lone star tick simulation model (lstsim) for a wildlife ecosystem was revised and expanded to include a beef cattle forage area and improved handling of tick-host-habitat interactions. relationships between environmental and biological variables were also refined in the new version. general validity of the revised model was established by comparing simulated and observed host-seeking populations of amblyomma americanum (l.) at five geographic locations, three in oklahoma an ... | 1993 | 8254630 |
| white-tailed deer as a potential reservoir of ehrlichia spp. | we determined the antibody prevalence to ehrlichia spp., in white-tailed deer (odocoileus virginianus) and the geographic distribution of seropositive animals in 84 counties in alabama, arkansas, florida, georgia, illinois, kentucky, louisiana, maryland, massachusetts, mississippi, missouri, north carolina, south carolina, tennessee, texas, virginia, and west virginia (usa). using an indirect fluorescent antibody test we detected antibodies (> or = 1:128) to this bacterium in 544 (43%) of 1269 d ... | 1994 | 8028099 |
| an update on the distribution of parelaphostrongylus tenuis in the southeastern united states. | an update is presented on the distribution of the meningeal worm (parelaphostrongylus tenuis) of white-tailed deer (odocoileus virginianus) in the southeastern united states. the parasite is widely distributed and common in all or much of arkansas, kentucky, louisiana, maryland, north carolina, tennessee, virginia and west virginia. it is also common in the northern half of alabama and georgia. in contrast, it is rare or absent along the atlantic and gulf coastal plains of alabama, georgia, miss ... | 1991 | 2067060 |
| management of lone star ticks (acari: ixodidae) in recreational areas with acaricide applications, vegetative management, and exclusion of white-tailed deer. | a project on management of lone star ticks, amblyomma americanum (l.), at land between the lakes, a tennessee valley authority recreational area in kentucky-tennessee, during 1984-1988, demonstrated the effectiveness and economics of three control technologies. acaricide applications (chlorpyrifos at 0.28 kg [ai]/ha), vegetative management (mowing and removal of 40% overstory and 90-100% of midstory, understory, and leaf litter), and host management (white-tailed deer exclusion from a 71-ha camp ... | 1990 | 1696994 |
| apteragia pursglovei sp. n. (trichostrongyloidea: trichostrongylidae) from the white-tailed deer, odocoileus virginianus. | two species of apteragia were found in white-tailed deer (odocoileus virginianus) from 152 counties in 13 southeastern states. specimens previously reported as skrjabinagia odocoilei were reidentified as belonging to 2 similar species of the genus apteragia, a. odocoilei, and a. pursglovei sp. n. apteragia pursglovei sp. n. is differentiated primarily by the length, conformation, and degree of sclerotization of the spicules. of the 824 deer, a. odocoilei occurred in 76.5%, a. pursglovei in 13.8% ... | 1979 | 448613 |
| culicoides, the vector of epizootic hemorrhagic disease in white-tailed deer in kentucky in 1971. | the biting gnat, culicoides variipennis (coquillett), was shown to be a vector of epizootic hemorrhagic disease (ehd) in white-tailed deer, odocoileus virginianus, in kentucky because of virus isolations from parous females. epidemiological evidence showed a close relationship of this vector to the animal host during an outbreak of ehd in penned deer. larval breeding sites of c. variipennis were found and c. variipennis was the most abundant biting fly present during the outbreak. females of c. ... | 1977 | 190421 |
| an outbreak of a hemorrhagic disease in white-tailed deer in kentucky. | in 1971, an outbreak of a hemorrhagic disease occurred in captive and free-ranging white-tailed deer (odocoileus virginianus) in mammoth cave national park, kentucky, clinical signs and gross pathological lesions were consistent with those of epizootic hemorrhagic disease and bluetongue, as were serological and histopathological findings for samples sent to other laboratories. the infection rate among the 104 captive deer was 88-92%, and that among the free-ranging park deer appeared to be simil ... | 1975 | 167205 |
| culture and serologic survey for mycobacterium avium subsp. paratuberculosis infection among southeastern white-tailed deer (odocoileus virginianus). | from july 1998 through october 2002, radiometric culture (ileocecal lymph node, mesenteric lymph node, and feces) and serologic testing by enzyme-linked immunosorbent assay (elisa) were used to survey white-tailed deer (odocoilens virgianus) from the soutlheastern united states for infection by mycobacterium avium subsp. paratuberculosis (mptb), the causative agent of paratuberculosis (johne's disease). mycobacterium avium subsp. paratuberculosis was isolated from the ileocecal lymph node of one ... | 2004 | 15362831 |
