trichuris oreamnos sp. n. from the mountain goat, oreamnos americanus (blainville), in british columbia, canada, and a key to trichurids in north american ruminants.		1974	4821114
contagious ecthyma in bighorn sheep and mountain goat in western canada.	contagious ecthyma (ce) is reported in bighorn sheep (ovis c. canadensis) from several national parks in western canada and in moutain goat (oreamnos americanus) from kootenay national park, british columbia. (this is the first report of ce in mountain goat.) diagnosis was based on clinical signs, histopathology, transmission experiments and the demonstration of a proxvirus with the electron microscope. the infection was transmitted from wild to domestic goat, but not to domestic sheep. most inf ...	1975	1113436
contagious ecthyma in mountain goat of coastal british columbia.	contagious ecthyma has been reported previously from mountain goat (oreamnos americanus) in one restricted area of eastern british columbia. a second focus of infection is reported for mountain goat from western british columbia. diagnosis was based on appearance of lesions at necropsy, histopathology and demonstration of poxvirus with the electron microscope. the epizootiology of this infection in mountain goat is discussed briefly.	1977	559107
evidence for bluetongue virus in canada: 1976-1979.	since the identification of approximately 1 400 bovine serological reactors to bluetongue virus in the okanagan valley of british columbia in 1976, there has been no evidence of virus establishment in canada. no clinical signs suggestive of bluetongue were observed. it was not possible to demonstrate viral activity at the time the seropositive animals were detected and subsequent serological testing supports the hypothesis that the virus has not become endemic or indeed survived in canadian catt ...	1982	6293686
an outbreak of q fever probably due to contact with a parturient cat.	thirty-three cases (24 definite, nine probable) of q fever were diagnosed in victoria county, cape breton, nova scotia from may to august, 1985. twenty-six of the cases occurred in residents of baddeck (population 900, attack rate 2.8 percent), and 21 of the cases occurred during the month of june. there was geographic clustering of the cases: 14 of the 33 (42 percent) lived or worked in four buildings located side by side in the center of town. a case control study revealed that 25 of 29 cases ...	1988	3335174
improved phenotyping of apolipoprotein e: application to population frequency distribution.	a simple procedure for phenotyping apolipoprotein (apo) e directly from plasma has been developed for use in the lipid clinic laboratory. in this new method, 10 microl of serum or plasma is pretreated with neuraminidase (ec 3.2.1.18), which removes the sialic acid residues from apo e and eliminates additional bands, thereby ensuring correct phenotype assignment. after a rapid delipidation step, the samples are focused in vertical polyacrylamide mini-slab gels and immunoblotted with a polyclonal ...	1990	2242561
escherichia coli o157 outbreak associated with the ingestion of unpasteurized goat's milk in british columbia, 2001.		2002	11806311
petting zoo-associated escherichia coli 0157:h7--secondary transmission, asymptomatic infection, and prolonged shedding in the classroom.		2004	15536809
geographic distribution of the muscle-dwelling nematode parelaphostrongylus odocoilei in north america, using molecular identification of first-stage larvae.	molecular identification of dorsal-spined larvae (dsl) from fecal samples indicates that the protostrongylid parasite parelaphostrongylus odocoilei occupies a broader geographic range in western north america than has been previously reported. we analyzed 2,124 fecal samples at 29 locations from thinhorn sheep (ovis dalli dalli and o. d. stonei), bighorn sheep (ovis canadensis canadensis and o. c. californiana), mountain goats (oreamnos americanus), woodland caribou (rangifer tarandus caribou), ...	2005	16108550
contact with livestock--a protective effect against allergies and asthma?	a 'protective farm factor' possibly related to livestock exposure is hypothesized to reduce the risk for allergic sensitization.	2006	16961711
does reduced heterozygosity influence dispersal? a test using spatially structured populations in an alpine ungulate.	despite having a profound effect on population dynamics, the reasons that animals disperse are poorly understood. evolutionary explanations have focused on inbreeding and competition, where the potential cost of philopatry is negated through dispersal. such scenarios lead to the prediction that less successful individuals preferentially disperse, termed 'fitness-associated dispersal'. since heterozygosity is associated with fitness, we assessed whether dispersed animals had less observed heteroz ...	2011	21270020
hot spots of genetic diversity descended from multiple pleistocene refugia in an alpine ungulate.	species that inhabit naturally fragmented environments are expected to be spatially structured and exhibit reduced genetic diversity at the periphery of their range. patterns of differentiation may also reflect historical processes such as recolonization from glacial refugia. we examined the relative importance of these factors in shaping the spatial patterns of genetic differentiation across the range of an alpine specialist, the north american mountain goat (oreamnos americanus). contrary to f ...	2011	20731714
