prevalence and effect of subclinical ovine progressive pneumonia virus infection on ewe wool and lamb production.	the prevalence of infection with ovine progressive pneumonia (opp) virus and its effects on ewe wool and lamb production were investigated in a flock of 2,976 ewes of 6 breed types (rambouillet, targhee, columbia, polypay, 1/4 cross finnsheep, and 1/2 cross finnsheep). prevalence of seropositivity was significantly (p less than or equal to 0.01) lower among rambouillet and targhee breeds (44 and 42%, respectively), intermediate in polypay, columbia, and 1/4 cross finnsheep (approximately 53%), a ...	1990	2170310
approaches to immunization of infants and young children against gastroenteritis due to rotaviruses.	recent studies have shown that in developed countries rotaviruses are the single most important etiologic agents of acute gastroenteritis that requires hospitalization of infants and young children. although deaths from gastroenteritis are, in general, infrequent in the developed countries, an effective rotavirus vaccine would clearly be of benefit to reduce the heavy toll of morbidity from gastroenteritis due to rotavirus. in the developing countries the impact of diarrheal diseases is staggeri ...	1980	6251528
frequency of bluetongue and bovine parvovirus infection in cattle in south carolina dairy herds.	a survey of south carolina diary cattle in 12 commercial herds was conducted, using serologic testing to determine the frequency and impact on reproduction of bluetongue (bt) and bovine parvovirus (bfv) infections. results of the study of serum antibodies titers and dairy cattle health records indicated that the majority of the cattle surveyed was adequately protected against the major reproductive tract diseases through vaccination programs. the frequency of reproductive dysfunction was common ...	1982	6285770
muellerius capillaris (mueller, 1889) (nematoda: protostrongylidae): an unusual finding in rocky mountain bighorn sheep (ovis canadensis canadensis shaw) in south dakota.	lungs and fecal samples from nine hunter-killed rocky mountain bighorn sheep were examined for lungworms. all samples contained adults and/or larvae of muellerius capillaris (mueller, 1889). protostrongylus spp., the lungworms commonly reported from bighorn sheep, were not present in any samples. larvae of m. capillaris bear a spine on the dorsal side of the posterior end and are shorter than dorsal-spined larvae of other lungworms recorded from north american ungulates. larvae similar in shape ...	1984	6530714
129i and 137cs fission products in thyroids of animals, 1984-1991.	iodine is intensely concentrated in the thyroid of animals, while 137cs is not. in this study, 129i and 137cs concentrations were determined in animal thyroids from selected areas during 1984-1991. the thyroids were from deer killed within the savannah river site (srs) in south carolina; from the environs of oak ridge (or), tennessee; west tennessee; and florida. thyroids from sheep slaughtered routinely in birmingham, england (uk), were also tested. the glands were analyzed by x-ray spectroscop ...	1993	8416215
seasonal dynamics and variation among sheep in densities of the sheep biting louse, bovicola ovis.	cyclic patterns and variations among sheep in numbers of bovicola ovis are described in polypay and columbia ewes that were initially infested with equal numbers of lice and penned indoors continuously for 2 years. bovicola ovis populations were censused at 3-4-week intervals at 69 body sites on each animal. in the second year of the study, the ewes were reinfested and half were mated. louse populations were monitored on the resulting lambs from birth until 25 weeks of age. strong seasonal cycle ...	1998	9512991

selenium toxicity in sheep grazing reclaimed phosphate mining sites.	phosphate mining operations in southeastern idaho have exposed selenium (se) that was originally sequestered in the subsurface. sheep grazing in these areas have died as a result of high se concentrations in forage and water. this study was designed to monitor the health status of sheep grazing in a natural environment with known elevated levels of se. a total of 72 columbia x suffolk sheep were divided into 3 treatment groups that included control (con), low selenium (lose) and high selenium (h ...	2003	14640477
