| bluetongue virus isolations from vectors and ruminants in central america and the caribbean. interamerican bluetongue team. | a regional prospective study of the epidemiology of bluetongue virus (btv) serotypes covering 11 countries in central america and the caribbean took place between 1987 and 1992. active surveillance revealed btv infection to be endemic in the absence of confirmed indigenous cases of bluetongue. during the 6-year span of the study, over 300 btv isolations were obtained from cattle and sheep. results of the earlier years of the study were summarized, and surveillance activities in the concluding mo ... | 1994 | 8172409 |
| duration of bluetongue viremia in experimentally infected american bison. | six yearling american bison (bison bison bison) bulls and one yearling ewe (ovis aries) were inoculated intradermally and subcutaneously with 2 x 10(5) plaque forming units (pfu) of bluetongue (bt) virus serotype 11. two uninoculated yearling bison bulls served as negative controls. blood samples were collected for serology and virus isolation on 0, 4, 7, 11 and 14 days post-inoculation (dpi) and every 2 wk thereafter to 127 dpi. every 4 wk a new ewe was inoculated with a pooled sample of whole ... | 2001 | 11763735 |
| hemorrhagic disease in deer in arizona. | two mule deer (odocoileus hemionus) and one white-tailed deer (odocoileus virginianus) in arizona (usa) were submitted for necropsy. gross and microscopic lesions compatible with hemorrhagic disease (hd) were observed in all three deer. epizootic hemorrhagic disease virus type 2 (ehdv-2) was isolated from two of the deer. to our knowledge, this is the first documentation of hd in deer in arizona. two of the mortalities were attributed to ehdv-2 infection. | 2002 | 11838211 |
| three new orbivirus species isolated from farmed white-tailed deer (odocoileus virginianus) in the united states. | we report the detection and gene coding sequences of three novel orbivirus species found in six dead farmed white-tailed deer in the united states. phylogenetic analyses indicate that the new orbiviruses are genetically closely related to the guangxi, mobuck, peruvian horse sickness, and yunnan orbiviruses, which are thought to be solely borne by mosquitos. however, four of the six viruses analyzed in this work were found as co-infecting agents along with a known cervid pathogen, epizootic hemor ... | 2019 | 31861885 |
