| intra-nasal inoculation of american bison (bison bison) with ovine herpesvirus-2 (ovhv-2) reliably reproduces malignant catarrhal fever. | sheep-associated malignant catarrhal fever (mcf) due to infection with ovine herpesvirus 2 (ovhv-2) is common in commercial herds of american bison ( bison bison). inability to propagate ovhv-2 in vitro has been a constraint on experimental studies of the disease. we sought to establish whether nasal secretions from sheep that shed ovhv-2 might induce the disease in bison and to define a minimum challenge dose. fourteen bison were nebulized with sheep nasal sections containing 10(3)-10(7) ovhv-2 ... | 2007 | 17846237 |
| mycobacterium avium subspecies paratuberculosis in bison (bison bison) from northern canada. | nested polymerase chain reaction (pcr) using the mycobacterium avium subspecies paratuberculosis (map)-specific region, locus 251, was used as a screening tool for the detection of map dna in fecal samples from northern canadian bison herds. further characterization of positive samples (26/835) was performed because map dna was found without signs of disease. strain typing, using pcr-restriction endonucleas assay (rea), was limited to two samples but revealed that the samples corresponded to a c ... | 2007 | 17984279 |
| prevalence of escherichia coli o157:h7 in the american bison (bison bison). | bison is becoming a popular meat source for consumers, but very little is known about the bison's status with respect to escherichia coli o157:h7. we conducted a study to determine the prevalence and identify virulence genes and pulsed-field genetic types of e. coli o157:h7 in bison. rectal contents and rectoanal mucosal swab (rams) samples were collected from a total of 342 bison at slaughter on seven different dates. isolation of e. coli o157:h7 was by enrichment, immunomagnetic separation, an ... | 2007 | 18044434 |
| historic distribution and challenges to bison recovery in the northern chihuahuan desert. | ecologists and conservationists have long assumed that large grazers, including bison (bison bison), did not occur in post-pleistocene southwestern north america. this perception has been influential in framing the debate over conservation and land use in the northern chihuahuan desert. the lack of an evolutionary history of large grazers is being used to challenge the validity of ranching as a conservation strategy and to limit the protection and reintroduction of bison as a significant compone ... | 2007 | 18173472 |
| wood bison population recovery and forage availability in northwestern canada. | forage availability was assessed to determine sustainable stocking rates for eight broadly defined vegetation types (treed uplands, treed lowlands, mixed tall shrub/sedge, closed-canopied willow, and open-canopied willow, meadow, wetland grass, wetland sedge) for use by wood bison (bison bison athabascae), a threatened subspecies, in the canadian boreal forest of northern alberta. clip plots (n=108) were used to sample peak availability of herbs and current annual growth of salix spp. in late su ... | 2009 | 18191321 |
| human influence on distribution and extinctions of the late pleistocene eurasian megafauna. | late pleistocene extinctions are of interest to paleontological and anthropological research. in north america and australia, human occupation occurred during a short period of time and overexploitation may have led to the extinction of mammalian megafauna. in northern eurasia megafaunal extinctions are believed to have occurred over a relatively longer period of time, perhaps as a result of changing environmental conditions, but the picture is much less clear. to consider megafaunal extinction ... | 2008 | 18199470 |
| antibiotic resistance of enterococci in american bison (bison bison) from a nature preserve compared to that of enterococci in pastured cattle. | enterococci isolated from a bison population on a native tall-grass prairie preserve in kansas were characterized and compared to enterococci isolated from pastured cattle. the species diversity was dominated by enterococcus casseliflavus in bison (62.4%), while enterococcus hirae was the most common isolate from cattle (39.7%). enterococcus faecalis was the second most common species isolated from bison (16%). in cattle, e. faecalis and enterococcus faecium were isolated at lower percentages (3 ... | 2008 | 18245252 |
| molecular anatomy of the cytoplasmic domain of bovine growth hormone receptor, a quantitative trait locus. | quantitative trait loci (qtl) studies have indicated growth hormone receptor (ghr) as a candidate gene affecting cattle milk yield and composition. in order to characterize genetic variation at ghr in cattle, we studied european and east african breeds with different histories of selection, and bos grunniens, ovis aries, sus scrofa, bison bison and rangifer tarandus as references. we sequenced most of the cytoplasmic domain (900 bp of exon 10), 89 bp of exon 8, including the putative causative m ... | 2008 | 18381258 |
| the ecological future of the north american bison: conceiving long-term, large-scale conservation of wildlife. | many wide-ranging mammal species have experienced significant declines over the last 200 years; restoring these species will require long-term, large-scale recovery efforts. we highlight 5 attributes of a recent range-wide vision-setting exercise for ecological recovery of the north american bison (bison bison) that are broadly applicable to other species and restoration targets. the result of the exercise, the "vermejo statement" on bison restoration, is explicitly (1) large scale, (2) long ter ... | 2008 | 18402580 |
| foot-and-mouth disease in north american bison (bison bison) and elk (cervus elaphus nelsoni): susceptibility, intra- and interspecies transmission, clinical signs, and lesions. | there is limited information about the pathogenesis and epidemiology of foot-and-mouth disease (fmd) in north american bison (bison bison) or elk (cervus elaphus nelsoni). in these two experimental infection studies, we compared the susceptibilities of bison and elk to fmd virus (fmdv), respectively, with that of cattle; determined whether intra- and interspecies transmission could occur in bison and cattle, and elk and cattle; determined suitability of conventional available laboratory tests to ... | 2008 | 18436660 |
| an outbreak of chronic pneumonia and polyarthritis syndrome caused by mycoplasma bovis in feedlot bison (bison bison). | mycoplasma bovis was identified by a specific lesion, conventional bacterial culture, immunohistochemistry, and polymerase chain reaction in 2 feedlot bison found dead with severe, chronic, caseonecrotic pneumonia; polyarthritis; and laryngitis. on microscopic examination, pulmonary lesions were characterized by prominent, well-defined areas of caseous necrosis and bronchiectasis. immunohistochemical analysis of lung exhibited staining in bronchiolar epithelium and in random areas of caseous nec ... | 2008 | 18460630 |
| the effect of ancient dna damage on inferences of demographic histories. | the field of ancient dna (adna) is casting new light on many evolutionary questions. however, problems associated with the postmortem instability of dna may complicate the interpretation of adna data. for example, in population genetic studies, the inclusion of damaged dna may inflate estimates of diversity. in this paper, we examine the effect of dna damage on population genetic estimates of ancestral population size. we simulate data using standard coalescent simulations that include postmorte ... | 2008 | 18653730 |
| first isolation of histophilus somni from goats. | histophilus somni (former name: haemophilus somnus) is a gram-negative, facultative pathogen bacterium that colonises the mucous membranes of cattle and sheep, however it was also described in american bison and bighorn sheep. it can cause local or generalised diseases and asymptomatic carriers can also occur. the presence and the etiological role of this microorganism have not been confirmed in any other domesticated species yet. the purpose of this study was to prove the presence of h. somni i ... | 2009 | 18774660 |
| recovery and cryopreservation of epididymal sperm of plains bison (bison bison bison) as a model for salvaging the genetics of wood bison (bison bison athabascae). | the objective of this study was to optimize recovery and cryopreservation of epididymal sperm from plains bison, as a model for wood bison. in phase 1, cauda epididymides were recovered from bison (n = 14) immediately after slaughter, minced and incubated in sp-talph buffer for 3 h at 36 degrees c. the resulting sperm suspensions were cryopreserved in triladyl, using a protocol for bovine semen. in phase 2, epididymal sperm were cryopreserved in either triladyl or andromed. the mean (+/-sd) esti ... | 2009 | 18811627 |
| clinical parelaphostrongylus tenuis infection in two captive american bison (bison bison). | 2 juvenile (17 and 19 months of age) male american bison (bison bison) were examined because of acute bilateral hind limb weakness and ataxia; 1 animal also had urinary incontinence. | 2008 | 18828725 |

| malignant catarrhal fever in a captive american bison (bison bison) in italy. | malignant catarrhal fever (mcf) is a fatal, systemic disease of cattle and other domestic and wild ruminants that, in europe, is caused by ovine herpesvirus 2 (ovhv-2). american bison (bison bison) are highly susceptible to the disease. an adult american bison, housed in a zoo in southern italy in close cohabitation with a group of domestic sheep (ovis aries aries) displayed clinical signs that resembled the acute form of mcf. by real-time polymerase chain reaction, ovhv-2 dna was detected intra ... | 2008 | 18987244 |
| patterns of genetic variation in us federal bison herds. | like many wide-ranging mammals, american bison (bison bison) have experienced significant range contraction over the past two centuries and are maintained in artificially isolated populations. a basic understanding of the distribution of genetic variation among populations is necessary to facilitate long-term germplasm preservation and species conservation. the 11 herds maintained within the us federal system are a critically important source of germplasm for bison conservation, as they include ... | 2008 | 19017265 |
| immunoexpression of aromatase in immature and adult males of the european bison (bison bonasus, linnaeus 1758). | based on recent literature dealing with the role of oestrogens in the male gonad, attempts were undertaken to reveal the site of aromatization within the testis of the european bison (bison bonasus). testes were collected from culled animals living in free-ranging populations in bialowieza forest, poland (nine males aged 8 months to 10 years). moreover, to check for any alterations in the expression of testicular aromatase between american bison (bison bison) and european bison, testes from one ... | 2010 | 19032431 |
| physical characteristics of rumen contents in four large ruminants of different feeding type, the addax (addax nasomaculatus), bison (bison bison), red deer (cervus elaphus) and moose (alces alces). | based on morphological and physiological observations, it has been suggested that differences exist in the degree that reticuloruminal (rr) contents are stratified between various ruminant species. however, the occurrence of stratification has hardly been measured in non-domestic species. forestomach contents of free-ranging moose (n=22) and red deer (24) shot during regular hunting procedures, and of captive (but 100% forage fed) addax (6) and bison (10) culled for commercial or management purp ... | 2009 | 19049897 |
| in vitro production of cattlexbuffalo hybrid embryos using cattle oocytes and african buffalo (syncerus caffer caffer) epididymal sperm. | interspecies hybridization of bovids occurs between domestic cattle and at least three other species; american bison (bison bison), yak (bos grunniens) and banteng (bos banteng). birth of a cattlexbuffalo (bubalus bubalis) hybrid has reportedly occurred in russia and in china, but these reports were not authenticated. such hybrids could be important in improving livestock production and management of diseases that impede production in tropical africa. this study investigated hybridization betwee ... | 2009 | 19118889 |
| banking north american buffalo semen. | the purpose of this study was to develop a procedure to collect and preserve semen from wood bison (bison bison athabascae) and plains bison (bison bison bison). semen samples from three wood and three plains bison bulls were collected by electroejaculation from june through october. in addition, sperm was collected from the cauda epididymis of seven plains bison. semen was cryopreserved using two commercially available cryopreservation media, an egg yolk-based medium (triladyl), and a medium fr ... | 2009 | 19181375 |
| pyric herbivory: rewilding landscapes through the recoupling of fire and grazing. | our understanding of fire and grazing is largely based on small-scale experimental studies in which treatments are uniformly applied to experimental units that are considered homogenous. any discussion of an interaction between fire and grazing is usually based on a statistical approach that ignores the spatial and temporal interactions on complex landscapes. we propose a new focus on the ecological interaction of fire and grazing in which each disturbance is spatially and temporally dependent o ... | 2008 | 19183203 |
| evaluation of hematologic values in free-ranging african buffalo (syncerus caffer). | as part of a large-scale disease screening program, blood samples were collected from 534 african buffalo (syncerus caffer) in south africa's hluhluwe-imfolozi park in october 2005 and may 2006 to establish age- and sex-specific reference intervals for erythrogram and leukogram values. sixty-seven of the animals were positive for bovine tuberculosis (tb), allowing for comparisons between tb-positive and tb-negative groups. positive animals had basopenia and slight lymphopenia compared to tb-nega ... | 2009 | 19204335 |
| enhanced immune response of red deer (cervus elaphus) to live rb51 vaccine strain using composite microspheres. | brucellosis is an important zoonotic disease of nearly worldwide distribution. the occurrence of the infection in humans is largely dependent on the prevalence of brucellosis in animal reservoirs, including wildlife. the current vaccine used for cattle brucella abortus strain rb51, has proven ineffective in protecting bison (bison bison) and elk (cervus nelsoni) from infection and abortion. to test possible improvements in vaccine efficacy, a novel approach of immunization was examined from apri ... | 2009 | 19204345 |
| occurrence and molecular characterization of cryptosporidium and giardia in captive wild ruminants in belgium. | both cryptosporidium and giardia are frequently found in the stool of domestic ruminants, especially young animals. wild ruminants are also host to these protozoa, but the prevalence of these parasites in both free-ranging and captive nondomesticated ruminants needs to be further investigated. moreover, the role of wild ruminants serving as reservoirs for these zoonotic parasites remains unclear. therefore, a cross-sectional survey was conducted to estimate the occurrence of cryptosporidium and ... | 2009 | 19368251 |
| even-toed but uneven in length: the digits of artiodactyls. | in captive ruminants housed in small enclosures, hypertrophy of the outer hooves of the hindlimbs is often observed. we hypothesised that the underlying cause is overload attributable to an asymmetry of the digits, especially with respect to their length. to test this hypothesis, the bones of the digits of four species of artiodactyls, which included 11 wild chamois (rupicapra rupicapra), 11 captive fallow deer (dama dama), 11 captive bison (bison bison) and 11 european moose (alces alces; 9 wil ... | 2009 | 19386479 |
| characterization and genetic analysis of bovine alpha s1-casein i variant. | the aim of this study was to identify the molecular genetic origin underlying the i variant of alpha(s1)-casein and to develop a dna-based test for this polymorphism as a tool for genetic analyses independent of milk sample testing. all coding exons and flanking regions of the alpha(s1)-casein gene were sequenced in dna samples from cattle of known alpha(s1)-casein genotypes (bi, ci, ii, cc), determined by isoelectric focusing of milk samples. a nucleotide substitution (a>t) in exon 11 (g.19836a ... | 2009 | 19392822 |
| conservation genetics and north american bison (bison bison). | the many millions of north american bison in the mid-19th century were reduced to near extinction by the middle 1880s. plains bison, the subspecies found in the united states, were saved from extinction primarily by 5 private ranchers and the survival of a small herd in what is now yellowstone national park. this bottleneck resulted in the present-day plains bison population being descended from less than 100 founders. in addition, many conservation herds have cattle ancestry because of hybridiz ... | 2009 | 19414501 |
| deletion/insertion polymorphism of the prion protein gene (prnp) in polish red cattle, polish white-backed cattle and european bison (bison bonasus l., 1758). | the aim of the present study was to identify deletion/insertion polymorphism of the bovine prion protein (prnp) gene within the promoter sequence (23 bp indel), intron 1 (12 bp indel) and the 3' end untranslated region (14 bp indel). the experiment was performed on three groups of animals protected under a genetic resources conservation program: 139 polish red (pr) cows, 79 polish white-backed cows and 50 european bison (bison bonasus l., 1758). white-backed cattle were characterized by a higher ... | 2009 | 19507705 |
| the need to rationalize and prioritize threatening processes used to determine threat status in the iucn red list. | thorough evaluation has made the international union for conservation of nature (iucn) red list the most widely used and accepted authority on the conservation status of biodiversity. although the system used to determine risk of extinction is rigorously and objectively applied, the list of threatening processes affecting a species is far more subjectively determined and has not had adequate review. i reviewed the threats listed in the iucn red list for randomly selected groups within the three ... | 2009 | 19508675 |

| [sarcocystis cruzi (protozoa: apicomplexa: sarcocystiidae) infection in european bison (bison bonasus) from białowieza forest, poland]. | samples of oesophagus, diaphragm and heart muscles were taken from one european bison from białowieza forest during seasonal european bison elimination in 2008. five gram of each muscle was examined by staining small samples in 0.2% aqueous solution of methylene blue. after that they were placed between compressor glasses and examined under a dissecting microscope in order to detect sarcocystis sp. infection. all sarcocysts observed were counted. the 5-g sample of the heart muscle yielded a tota ... | 2009 | 19579782 |
| pathogenesis and epidemiology of brucellosis in yellowstone bison: serologic and culture results from adult females and their progeny. | our objective in this prospective study was to determine the natural course of brucella abortus infection in cohorts of seropositive and seronegative, female bison (bison bison) and their offspring in yellowstone national park (ynp) for 5 yr. we collected specimens from 53 adult females and 25 calves at least once and from 45 adults and 22 calves more than once. annual seroconversion rates (negative to positive) were relatively high (23% for calves and juvenile bison, 6% in the total sample of a ... | 2009 | 19617483 |
| divergent evolution in the cytoplasmic domains of prlr and ghr genes in artiodactyla. | prolactin receptor (prlr) and growth hormone receptor (ghr) belong to the large superfamily of class 1 cytokine receptors. both of them have been identified as candidate genes affecting key quantitative traits, like growth and reproduction in livestock. we have previously studied the molecular anatomy of the cytoplasmic domain of ghr in different cattle breeds and artiodactyl species. in this study we have analysed the corresponding cytoplasmic signalling region of prlr. | 2009 | 19622175 |
| effectiveness of microsatellite and snp markers for parentage and identity analysis in species with low genetic diversity: the case of european bison. | the european bison (bison bonasus) has recovered successfully after a severe bottleneck about 90 years ago but has been left with low genetic variability that may substantially hinder parentage and identity analysis. according to pedigree analysis, over 80% of the genes in the contemporary population descend from just two founder animals and inbreeding coefficients averaged almost 0.5, whereas microsatellite heterozygosity does not exceed 0.3. we present a comparison of the effectiveness of 17 m ... | 2009 | 19623210 |
| age-dependent pattern of connexin43 expression in testes of european bison (bison bonasus, l.). | morphology and the expression of connexin43 (cx43) was investigated in testes of immature, prepubertal, and adult european bison bulls by means of routine histology, immunohistochemistry, and western blotting, respectively. testes were collected from culled animals living in bialowieza and borecka forests, poland. histological examination of testicular tissue of immature and prepubertal males revealed normal structure, whereas of adult individuals either normal testicular structure with advanced ... | 2009 | 19623571 |
| group-size-mediated habitat selection and group fusion-fission dynamics of bison under predation risk. | for gregarious animals the cost-benefit trade-offs that drive habitat selection may vary dynamically with group size, which plays an important role in foraging and predator avoidance strategies. we examined how habitat selection by bison (bison bison) varied as a function of group size and interpreted these patterns by testing whether habitat selection was more strongly driven by the competing demands of forage intake vs. predator avoidance behavior. we developed an analytical framework that int ... | 2009 | 19769126 |
| ashworthius sidemi (nematoda, trichostrongylidae) in wild ruminants in białowieza forest. | between 2003-2007, abomasa of 91 european bison (bison bonasus), 4 red deer (cervus elaphus) and 2 roe deer (capreolus capreolus) shot in the białowieza primeval forest (poland) were examined for worms presence. all the animals examined were infected with nematodes a. sidemi with an exception of one bison, that was shot in year 2003. there was much higher average intensity of invasion in bison (5529), than in red deer (85) and in roe deer (1837). the animals were shot in a period from december t ... | 2009 | 19886261 |
| oral vaccination with microencapsuled strain 19 vaccine confers enhanced protection against brucella abortus strain 2308 challenge in red deer (cervus elaphus elaphus). | bison (bison bison) and elk (cervus elaphus nelsoni) in the greater yellowstone area (gya), usa, are infected with brucella abortus, the causative agent of bovine brucellosis, and they serve as a wildlife reservoir for the disease. bovine brucellosis recently has been transmitted from infected elk to cattle in montana, wyoming, and idaho and has resulted in their loss of brucellosis-free status. an efficacious brucella vaccine with a delivery system suitable for wildlife would be a valuable tool ... | 2009 | 19901378 |
| experimental nebulization of american bison (bison bison) with low doses of ovine herpesvirus 2 from sheep nasal secretions. | malignant catarrhal fever (mcf), caused by ovine herpesvirus 2 (ovhv-2), is an important cause of mortality in ranched american bison and domestic cattle in north america. previous studies showed that bison can be infected by intranasal nebulization with sheep nasal secretions containing ovhv-2 and provided preliminary information on viral doses required for infection and disease progression. the goals of this study were to establish optimal minimal infectious and minimal lethal doses of ovhv-2 ... | 2010 | 20018461 |
