| [non-indigenous and non-specific parasitic nematodes--the background and the consequences]. | introduction of the host is the main reason behind introduction of the parasite, e. g., nematodes. the introduction of the japanese eel (anguilla japonica) in europe in the 1980s resulted in expansion of the swimbladder nematode anguillicola crassus which soon invaded not only populations of the european eel (a. anguilla), but also other local fish. the raccoon (procyon lotor) is native to north america. it is the specific host of strongyloides procyonis and baylisascaris procyonis. more than 90 ... | 2009 | 20209803 |
| vaccination strategies for managing brucellosis in yellowstone bison. | concerns over migratory bison (bison bison) at yellowstone national park transmitting brucellosis (brucella abortus) to cattle herds on adjacent lands led to proposals for bison vaccination. we developed an individual-based model to evaluate how brucellosis infection might respond under alternate vaccination strategies, including: (1) vaccination of female calves and yearlings captured at the park boundary when bison move outside the primary conservation area; (2) combining boundary vaccination ... | 2010 | 20362620 |
| brucellosis in the united states: role and significance of wildlife reservoirs. | regulatory programs for brucellosis in domestic livestock have been active in the u.s. for almost 80 years. wildlife reservoirs of brucellosis include bison (bison bison) and elk (cervus elaphus nelsonii) for brucella abortus whereas brucella suis is the predominant species infecting feral swine. the persistence of brucellosis in wildlife reservoirs poses a risk for reintroduction of brucella into domestic livestock. reducing the prevalence of brucellosis in wildlife reservoirs is anticipated to ... | 2010 | 20362627 |
| characterization of bison (bison bison) myoglobin. | bison is an alternate meat species gaining increased popularity in north america. although previous investigations reported that bison meat discolors faster than beef, the molecular basis of this observation has not been investigated. therefore, the objective of the present study was to determine the redox stability, thermostability, and primary structure of bison myoglobin (mb), in comparison with beef mb. purified bison and beef myoglobins were analyzed for autoxidation, lipid oxidation-induce ... | 2010 | 20374756 |

| quantification of damage at different stages of cryopreservation of endangered north american bison (bison bison) semen and the effects of extender and freeze rate on post-thaw sperm quality. | semen cryopreservation is an important technique for the banking of animal germplasm from endangered species and exploitation of genetically superior sires through artificial insemination. being a member of bovidae family, bison semen has poor freezing ability as compared to dairy and beef bulls' semen. this study was designed to quantify the damage to bison sperm at different stages of cryopreservation, and to determine the effects of extender (commercial triladyl(®) vs. custom made tris-citric ... | 2011 | 22240453 |
| toxocara vitulorum in a bison (bison bison) herd from western canada. | the discovery of the parasite toxocara vitulorum in bison calves in the province of manitoba, canada is discussed. this parasite is more commonly found in the small intestines of bovid calves living in tropical and subtropical regions of the world. this is the first time that toxocara vitulorum has been reported from hosts in canada. | 2012 | 23277649 |
| immune responses and safety after dart or booster vaccination of bison with brucella abortus strain rb51. | one alternative for management of brucellosis in yellowstone national park bison (bison bison) is vaccination of calves and yearlings. although brucella abortus strain rb51 vaccination protects bison against experimental challenge, the effect of booster vaccinations was unknown. this study characterized immunologic responses after dart or booster vaccination of bison with brucella abortus strain rb51. in two studies, 8- to 10-month-old female bison were inoculated with saline (n = 14), hand vacc ... | 2012 | 22461528 |
| farm crops depredation by european bison (bison bonasus) in the vicinity of forest habitats in northeastern poland. | european bison, the largest mammal in europe, after being exterminated in the wild and then restored during the 20th century is still listed by the international union for conservation of nature (iucn red list of threatened species) as a species vulnerable to extinction. however, the increasing number of european bison, through creation of new and expansion of existing populations strongly increases the risk of human-bison conflict in the near future. we analyzed the depredation of farm crops by ... | 2012 | 22842710 |
| sequence analysis of bitter taste receptor gene repertoires in different ruminant species. | bitter taste has been extensively studied in mammalian species and is associated with sensitivity to toxins and with food choices that avoid dangerous substances in the diet. at the molecular level, bitter compounds are sensed by bitter taste receptor proteins (t2r) present at the surface of taste receptor cells in the gustatory papillae. our work aims at exploring the phylogenetic relationships of t2r gene sequences within different ruminant species. to accomplish this goal, we gathered a colle ... | 2015 | 26061084 |
| first steps into the wild - exploration behavior of european bison after the first reintroduction in western europe. | biodiversity is rapidly declining globally. one strategy to help to conserve species is to breed species in captivity and release them into suitable habitats. the way that reintroduced animals explore new habitats and/or disperse from the release site is rarely studied in detail and represents key information for the success of reintroduction projects. the european bison (bison bonasus l. 1758) was the largest surviving herbivore of the post-glacial megafauna in europe before it became extinct i ... | 2015 | 26605549 |
| evidence of low prevalence of mycobacterial lymphadenitis in wild boars (sus scrofa) in poland. | mycobacterium spp. and rhodococcus equi are generally regarded as the main causes of lymphadenitis in pigs and wild boars. in poland, mycobacterial submandibular lymphadenitis was first diagnosed in a wild boar in 2012 but mycobacterium spp. infections are also present in the polish population of european bison (bison bonasus). the prevalence of lymphadenitis in polish wild boars has been found to 8.4% (95% ci 6.2-11.3%) and it has been proved that r. equi is not an important cause of purulent l ... | 2017 | 28122588 |
| black-tailed prairie dogs, cattle, and the conservation of north america's arid grasslands. | prairie dogs (cynomys spp.) have been eliminated from over 95% of their historic range in large part from direct eradication campaigns to reduce their purported competition with cattle for forage. despite the longstanding importance of this issue to grassland management and conservation, the ecological interactions between cattle and prairie dogs have not been well examined. we address this issue through two complementary experiments to determine if cattle and prairie dogs form a mutualistic gra ... | 2015 | 25760377 |
| hunting the extinct steppe bison (bison priscus) mitochondrial genome in the trois-frères paleolithic painted cave. | despite the abundance of fossil remains for the extinct steppe bison (bison priscus), an animal that was painted and engraved in numerous european paleolithic caves, a complete mitochondrial genome sequence has never been obtained for this species. in the present study we collected bone samples from a sector of the trois-frères paleolithic cave (ariège, france) that formerly functioned as a pitfall and was sealed before the end of the pleistocene. screening the dna content of the samples collect ... | 2015 | 26083419 |
| tracking of wisent-bison-yak mitochondrial evolution. | one of the most informative sources which allow the drawing of far-reaching conclusions about the origins and phylogenetics of many species, including domestic animals and humans, is mitochondrial dna (mtdna). one of the important research targets should include the identification of similarities between wild and domestic species. the analysis involved the nucleotide sequences of mtdna of wisent, auroch, bison, yak, bovine reference sequence (brs) t3, t3a, t3b, t1, t1a, t1'2'3, t2, t3, t4, t5, q ... | 2012 | 22415349 |
| inferring the phylogeny of bovidae using mitochondrial dna sequences: resolving power of individual genes relative to complete genomes. | molecular techniques that assess biodiversity through the analysis of a small segment of mitochondrial genome have been getting wide attention for inferring the mammalian diversity. due to their highly conserved nature, specific mitochondrial genes offer a promising tool for phylogenetic analysis. however, there is no established criteria for selecting the typical mitochondrial dna (mtdna) segments to achieve a greater resolving power. we therefore chose the family bovidae as a model and compare ... | 2012 | 22399841 |
| seasonal shifts in diet and gut microbiota of the american bison (bison bison). | north american bison (bison bison) are becoming increasingly important to both grassland management and commercial ranching. however, a lack of quantitative data on their diet constrains conservation efforts and the ability to predict bison effects on grasslands. in particular, we know little about the seasonality of the bison diet, the degree to which bison supplement their diet with eudicots, and how changes in diet influence gut microbial communities, all of which play important roles in ungu ... | 2015 | 26562019 |
| mitochondrial genome analysis reveals historical lineages in yellowstone bison. | yellowstone national park is home to one of the only plains bison populations that have continuously existed on their present landscape since prehistoric times without evidence of domestic cattle introgression. previous studies characterized the relatively high levels of nuclear genetic diversity in these bison, but little is known about their mitochondrial haplotype diversity. this study assessed mitochondrial genomes from 25 randomly selected yellowstone bison and found 10 different mitochondr ... | 2016 | 27880780 |
| novel graphical analyses of runs of homozygosity among species and livestock breeds. | runs of homozygosity (roh), uninterrupted stretches of homozygous genotypes resulting from parents transmitting identical haplotypes to their offspring, have emerged as informative genome-wide estimates of autozygosity (inbreeding). we used genomic profiles based on 698 k single nucleotide polymorphisms (snps) from nine breeds of domestic cattle (bos taurus) and the european bison (bison bonasus) to investigate how roh distributions can be compared within and among species. we focused on two len ... | 2016 | 27872841 |
| early cave art and ancient dna record the origin of european bison. | the two living species of bison (european and american) are among the few terrestrial megafauna to have survived the late pleistocene extinctions. despite the extensive bovid fossil record in eurasia, the evolutionary history of the european bison (or wisent, bison bonasus) before the holocene (<11.7 thousand years ago (kya)) remains a mystery. we use complete ancient mitochondrial genomes and genome-wide nuclear dna surveys to reveal that the wisent is the product of hybridization between the e ... | 2016 | 27754477 |
| lack of effects of ooplasm transfer on early development of interspecies somatic cell nuclear transfer bison embryos. | successful development of iscnt (interspecies somatic cell nuclear transfer) embryos depends on complex interactions between ooplasmic and nuclear components, which can be compromised by genetic divergence. transfer of ooplasm matching the genetic background of the somatic cell in iscnt embryos is a valuable tool to study the degree of incompatibilities between nuclear and ooplasmic components. this study investigated the effects of ooplasm transfer (ot) on cattle (bos taurus) and plains bison ( ... | 2016 | 27737629 |
| lessons for livestock genomics from genome and transcriptome sequencing in cattle and other mammals. | decreasing sequencing costs and development of new protocols for characterizing global methylation, gene expression patterns and regulatory regions have stimulated the generation of large livestock datasets. here, we discuss experiences in the analysis of whole-genome and transcriptome sequence data. | 2016 | 27534529 |
| foraging decisions underlying restricted space use: effects of fire and forage maturation on large herbivore nutrient uptake. | recent models suggest that herbivores optimize nutrient intake by selecting patches of low to intermediate vegetation biomass. we assessed the application of this hypothesis to plains bison (bison bison) in an experimental grassland managed with fire by estimating daily rates of nutrient intake in relation to grass biomass and by measuring patch selection in experimental watersheds in which grass biomass was manipulated by prescribed burning. digestible crude protein content of grass declined li ... | 2016 | 27547359 |
