california serogroup virus infections in wisconsin domestic animals.a serologic survey and experimental virus transmission studies were done to assess the role of domestic animals as amplifier hosts of la crosse (lacv) and jamestown canyon (jcv) viruses. serum from 319 cows, 88 dogs, 122 equines, 47 swine, 10 goats, and 4 cats were tested for neutralizing antibody to lacv, jcv, trivittatus (tvtv), and snowshoe hare (sshv) viruses. antibody prevalences of lacv, tvtv, and sshv were less than 10% in all species. antibody to jcv was detected in all species except ca ...19883189702
immunoassays to study prevalence of antibody against gb virus c in blood donors.immunoassays were developed to determine the seroprevalence of antibody against human gb virus c (gbv-c). the antigenic target in each assay was a 44.6-kda glycosylated protein representing the first 315 amino acids encoded by the gbv-c e2 gene. sera or plasma were assayed for e2 antibody using an anti-human eia format in which antigen-coated polystyrene beads were reacted with sample, and bound antibody was detected by addition of enzyme labelled goat anti-human igg. the presence of anti-e2 ant ...19979395139
rabies surveillance in the united states during 2004.during 2004, 49 states and puerto rico reported 6,836 cases of rabies in nonhuman animals and 8 cases in human beings to the cdc, representing a 4.6% decrease from the 7,170 cases in nonhuman animals and 3 cases in human beings reported in 2003. approximately 92% of the cases were in wildlife, and 8% were in domestic animals (compared with 91% and 9%, respectively, in 2003). relative contributions by the major animal groups were as follows: 2,564 raccoons (37.5%), 1,856 skunks (27.1%), 1,361 bat ...200516379626
eimeria caprovina sp. n. from the domestic goat, capra hircus, from the usa.oocysts of eimeria caprovina sp. n. from the domestic goat, capra hircus, are ellipsoidal, subspherical or slightly ovoid, usually flattened at the micropylar end. they measure 29.7 (26-36) x 23.7 (23-28) micron. the sporocysts are elongate ovoids, measuring 14.3 (13.7) x 8.3 (8-9) micron, with stieda bodies at the narrow ends. the oocyst wall is 1.6 micron thick, smooth, dark-brown to brownish-yellow, and 2-layered. a micropyle, 6.2 (4-10) micron in diameter, polar granule, and sporocyst residu ...19807400993
bluetongue disease and the molecular epidemiology of viruses from the western united states.prototype and field isolates of united states bluetongue viruses were evaluated for genetic heterogeneity by sequence analyses. prototype viruses btv 2, 10, 11, 13 and 17 from the united states, btv 10 vaccine virus, and field isolates of btv 10 and 17 from california were analyzed. gene segment 2 from btv 10 and 17 isolated in 1980-81 and 1990 was sequenced along with gene segment 9 from btv 10 isolates. the wisconsin package was used to analyze nucleotide sequences and to predict amino acid co ...19968800543
effect of prepartum photoperiod on milk production and prolactin concentration of dairy ewes.long photoperiods during established lactation increase milk production in dairy cattle and dairy sheep, but recent research in cattle and dairy goats suggests an additional influence of prepartum day length on milk yield in the subsequent lactation. the proposed mechanism of function is the level and role of circulating prolactin in mammary development. the objectives of this study were to evaluate the effect of prepartum photoperiod on milk production, milk composition, and prolactin concentra ...200818096928
epidemiologic and experimental studies on transmissible mink encephalopathy.transmissible mink encephalopathy (tme) is a rare foodborne disease of ranch-raised mink produced by an as yet unidentified contaminated feed ingredient. because of the clinicopathologic similarities to scrapie and the indistinguishable physicochemical properties of their transmissible agents, it was initially assumed that tme was caused by feeding mink scrapie-infected sheep. however, subsequent studies testing the oral susceptibility of mink to scrapie were unsuccessful. epidemiologic investig ...19938270100
