an evolving pattern of human hydatid disease transmission in the united states.	echinococcus granulosus infection was being acquired in the contiguous united states by virginia sharecroppers and small-holders by the turn of the century. the last recorded human infection from that general area was diagnosed in 1947. by 1920 human infections were also being acquired in the lower mississippi valley. apparently, infection in both of these areas was maintained chiefly in swine. by 1940 a third transmission area definitely existed in the central valley of california, with its res ...	1977	329700
echinococcus granulosus in dogs and sheep in central utah, 1971-1976.	during 1971 to 1976, a survey was conducted to determine the prevalence of echinococcus granulosus infection among dogs and sheep in central utah. for each year, the number of dogs positive for adult tapeworms of the total number examined and the percentage infected were: in 1971, 14 of 51 infected (27.4%); in 1972, 13 of 46 infected (28.3%); in 1973, 7 of 36 infected (19.4%); in 1974, 34 of 244 infected (13.9%); in 1975, 13 of 267 infected (4.9%); and in 1976, 14 of 195 infected (7.2%), or a 6- ...	1978	637397
hydatid disease screening: sanpete county, utah, 1971-1976.	between 1971 and 1976 approximately 20% (2,265) of the population of sanpete county, utah, was screened for hydatid disease (echinococcus granulosus) by intradermal, indirect hemagglutination, and bentonite flocculation tests. of 34 persons who had follow-up chest radiographs and radioisotope liver scans, 6 were found to have asymptomatic hepatic cysts. if a participant who had pulmonary cysts and negative screening tests were included, the prevalence of asymptomatic hydatid disease would be 3 p ...	1978	626286
survey of chronic sinusitis-induced skull anomalies in desert bighorn sheep.	bone anomalies were found in 20% of 630 skulls from desert bighorn sheep (ovis canadensis) representing populations of california bighorn (o canadensis californiana), lower california bighorn (o canadensis cremnobates), mexican bighorn (o canadensis mexicana), and nelson bighorn (o canadensis nelsoni) that are native to arizona, california, nevada, new mexico, and utah. the anomalies were extremely diverse, ranging from osteonecrosis within the matrix of the paranasal sinuses to extensive lysis ...	1981	7327996

possible factors influencing distribution and prevalence of echinococcus granulosus in utah.	a descriptive epidemiologic study was designed to test an impression that infections of echinococcus granulosus in dogs, sheep, and human beings were concentrated in central utah, and to determine when and how the parasite was introduced into the state, which factors were involved in the distribution of the cestode, and which factors increased either a person's risk of infection of the number of people at risk. data were secured by review of available records, interviews, questionnaires, and fie ...	1982	7124714
scientists implicated in atom test deception.	described here are the circumstances leading to a recent court ruling that atomic energy commission officials suppressed data indicating a link between two 1953 atomic bomb tests in nevada and sheep deaths in neighboring utah, and then pressured scientific investigators to concur with the aec position. in a 1956 trial, a federal judge denied compensation to the sheep owners. evidence of the deception came to light in 1979 and 1980 and, on 24 august 1982, the same judge ordered a new trial, rul ...	1982	11643806
prevalence and causes of ram epididymitis in utah.	palpation of the testicles and epididymides was used to determine the prevalence of ram epididymitis (re) in utah range flocks over a 5-year period. of 62 range flocks examined, 58 had rams with palpable lesions. a comparison was made of prevalence by right vs left testicle involvement, but no significant difference was found. culling all rams with palpable lesions from the flock progressively reduced the annual incidence, but did not eliminate re from any flock. semen and specimens of reproduct ...	1985	3997640
susceptibility of beta-hemolytic streptococci to nine antimicrobial agents among four medical centers in salt lake city, utah, usa.	a multicenter study was performed to evaluate the susceptibility of beta-hemolytic streptococci to nine antimicrobial agents. mics were performed in cation-supplemented mueller-hinton broth with 3.5% lysed sheep red blood cells according to nccls guidelines. a total of 646 isolates were tested: 300 (46%) group a; 170 (26%) group b; 38 (6%) group c, 35 (5%) group f; 83 (17%) group g; and 20 (3%) nongroupable. six percent of the total isolates were resistant to one or more of the antibiotics teste ...	1997	9154408
the distribution of dermacentor hunteri and anaplasma sp. in desert bighorn sheep (ovis canadensis).	the ixodid tick dermacentor hunteri has been collected intermittently this century, primarily from desert bighorn sheep (ovis canadensis). anaplasma spp. are intraerythrocytic rickettsial parasites of ungulates and are vectored in the western united states by ticks of the genus dermacentor. we tested the hypotheses that d. hunteri would be found infesting all populations of desert bighorn, and that all infested populations would be seropositive for anaplasma sp. dermacentor hunteri was found on ...	1997	9057693

infection and thrombosis in total artificial heart technology: past and future challenges--a historical review.	on the basis of animal testing and a single clinical implant during the 1960s, development of the total artificial heart (tah) began in earnest in the 1970s. the goal was to produce a pump that could treat biventricular heart failure or any other condition that necessitated removal of the patient's native heart. the early tahs were pneumatically powered, with externalized drivelines. after undergoing in vivo evaluation in hundreds of sheep and calves at several centers (mainly the utah heart ins ...	2000	11110290
molecular epidemiologic features of corynebacterium pseudotuberculosis isolated from horses.	to characterize isolates of corynebacterium pseudotuberculosis from horses, cattle, and sheep in colorado, kentucky, utah, and california in samples collected during perceived epidemics of infection (increased numbers of cases identified) in 2002 and 2003, and determine how closely isolates were related and their possible source.	2004	15631043
legacies of land use and recent climatic change: the small mammal fauna in the mountains of utah.	climate warming will continue alongside human modification of the landscape. therefore, studying systems modified by land use may highlight factors that mitigate or exacerbate predicted biological responses to ongoing climate warming. using historical museum specimen records and recent field surveys, i examine temporal patterns in the ecological dynamics of the small mammal fauna on five mountain ranges in central utah over time intervals of 27-53 years during the past century. this landscape wa ...	2007	17874375
ecology of gastropod and bighorn sheep hosts of lungworm on isolated, semiarid mountain ranges in utah, usa.	isolated, nonmigratory populations of bighorn sheep (ovis canadensis) may experience high exposure to lungworms (protostrongylus spp.) through a build-up of fecal material. however, semiarid climates may hinder lungworm transmission by limiting terrestrial gastropods, the intermediate hosts. we assessed potential for lungworm transmission, documented occurrence of transmission, and identified habitat types where transmission was likely to occur on ranges of two recently introduced populations of ...	2008	18263819
mechanisms of resistance for streptococcus pyogenes in northern utah.	the purpose of this study was to (1) determine the rates of penicillin and erythromycin resistance among streptococcus pyogenes isolates in northern utah, and (2) determine the genotype of the erythromycin resistant strains, thereby providing information regarding the mechanism of the resistance.	2009	19354028
supplementing endophyte-infected tall fescue or reed canarygrass with alfalfa or birdsfoot trefoil increases forage intake and digestibility by sheep.	background: we hypothesized that alfalfa (alf) or birdsfoot trefoil (bft) eaten prior to a meal of endophyte-infected tall fescue (tf) or reed canarygrass (rcg) would provide benefits not possible when tf or rcg are eaten alone. in trial 1, four groups of five lambs were first offered alf for 30 min followed by either tf or rcg for 3.5 h in a 2 × 2 factorial arrangement of a completely randomized design that included grass (tf or rcg) with or without alf. trial 2 was similar to trial 1 except we ...	2011	22002685
