| epizootiology of bluetongue: the situation in the united states of america. | bluetongue was first reported in the united states in 1948 in sheep in texas. the virus has now been isolated from sheep in 19 states. when the disease first occurs in a flock, the morbidity may reach 50 to 75% and mortality 20 to 50%. in subsequent years, the morbidity may be only 1 to 2% with very few deaths. difference in breed susceptibility has not been observed. natural bluetongue infection has not been observed in angora or dairy goats. bluetongue virus was first isolated from cattle, in ... | 1975 | 169793 |

| phenotypic and phylogenetic characterization of ruminal tannin-tolerant bacteria. | the 16s rrna sequences and selected phenotypic characteristics were determined for six recently isolated bacteria that can tolerate high levels of hydrolyzable and condensed tannins. bacteria were isolated from the ruminal contents of animals in different geographic locations, including sardinian sheep (ovis aries), honduran and colombian goats (capra hircus), white-tail deer (odocoileus virginianus) from upstate new york, and rocky mountain elk (cervus elaphus nelsoni) from oregon. nearly compl ... | 1998 | 9758806 |
| muscleworms, parelaphostrongylus andersoni (nematoda: protostrongylidae), discovered in columbia white-tailed deer from oregon and washington: implications for biogeography and host associations. | parelaphostrongylus andersoni is considered a characteristic nematode infecting white-tailed deer (odocoileus virginianus). host and geographic distribution for this parasite, however, remain poorly defined in the region of western north america. fecal samples collected from columbia white-tailed deer (o. v. leucurus) in a restricted range endemic to oregon and washington, usa, were examined for dorsal-spined larvae characteristic of many protostrongylid nematodes. multilocus dna sequence data ( ... | 2008 | 18263818 |
| serosurvey for antibody to deerpox virus in five cervid species in oregon, usa. | five cervid species in oregon, usa were tested with a serum neutralization assay for antibody to deerpox virus (dpv). none of the 50 elk (cervus elaphus ssp. roosevelti and nelsonii) had detectable antibody. prevalence of antibody to dpv in the remaining species was: 52% (n=55) in black-tailed deer (odocoileus hemionus columbianus), 32% (n= 59) in mule deer (o. hemionus hemionus), and 36% (n=50) in columbian white-tailed deer (o. virginianus leucurus), with an overall antibody prevalence of 40.2 ... | 2013 | 23307387 |
