prehistoric contacts over the straits of gibraltar indicated by genetic analysis of iberian bronze age cattle.the geographic situation of the iberian peninsula makes it a natural link between europe and north africa. however, it is a matter of debate to what extent african influences via the straits gibraltar have affected iberia's prehistoric development. because early african pastoralist communities were dedicated to cattle breeding, a possible means to detect prehistoric african-iberian contacts might be to analyze the origin of cattle breeds on the iberian peninsula. some contemporary iberian cattle ...200515941827
variability and evolution of bovine beta-defensin genes.defensins comprise an important family of antimicrobial peptides. among vertebrates numerous defensin genes have been detected, but their evolutionary background is still discussed. we investigated the molecular evolution of bovine defensins via screening of different bovine species including the extinct ancestor of domestic cattle (bos primigenius) for beta-defensin encoding genes. we detected a large variability of new defensin encoding sequences similar to previously published bovine neutroph ...200515674371
close genetic relationship of early neolithic cattle from ziegelberg (freising, germany) with modern breeds.in 2003 a variety of crafts and bone specimens were found during excavations of a neolithic settlement near freising, the southernmost site of the linear pottery culture in bavaria. six cattle bones were used to extract ancient dna (adna). applying nested and touchdown pcr, two fragments of the mitochondrial (mt) dna control region could be amplified from specimen 533/iii which yielded a total of 230 base pairs (bp). the sequence was compared with the homologous part of 40 extant breeds of bos t ...200516130455
cattle domestication in the near east was followed by hybridization with aurochs bulls in europe.domesticated cattle were one of the cornerstones of european neolithisation and are thought to have been introduced to europe from areas of aurochs domestication in the near east. this is consistent with mitochondrial dna (mtdna) data, where a clear separation exists between modern european cattle and ancient specimens of british aurochsen. however, we show that y chromosome haplotypes of north european cattle breeds are more similar to haplotypes from ancient specimens of european aurochsen, th ...200516243693
independent mitochondrial origin and historical genetic differentiation in north eastern asian cattle.in order to clarify the origin and genetic diversity of cattle in north eastern asia, this study examined mitochondrial displacement loop sequence variation and frequencies of bos taurus and bos indicus y chromosome haplotypes in japanese, mongolian, and korean native cattle. in mitochondrial analyses, 20% of mongolian cattle carried b. indicus mitochondrial haplotypes, but japanese and korean cattle carried only b. taurus haplotypes. in contrast, all samples revealed b. taurus y chromosome hapl ...200415223036
heteroplasmy in bovine fetuses produced by intra- and inter-subspecific somatic cell nuclear transfer: neutral segregation of nuclear donor mitochondrial dna in various tissues and evidence for recipient cow mitochondria in fetal blood.varying degrees of mitochondrial dna (mtdna) heteroplasmy have been observed in nuclear transfer embryos, fetuses, and offspring, but the mechanisms leading to this condition are unknown. we have generated a clone of 12 bovine somatic cell nuclear transfer fetuses, using nuclear donor cells, recipient oocytes, and recipient heifers with defined mtdna genotypes, to study nuclear-mitochondrial interactions and the origins of mtdna heteroplasmy. embryos were reconstructed from granulosa cells with ...200312493708
healthy skin of many animal species harbors papillomaviruses which are closely related to their human counterparts.papillomaviruses associated with clinical symptoms have been found in many vertebrate species. in this study, we have used an l1 gene consensus pcr test designed to detect a broad spectrum of human skin papillomaviruses to analyze swab samples from healthy skin of 111 animals belonging to 19 vertebrate species. in eight of the species, papillomavirus dna was found with the following prevalences: chimpanzees, 9 of 11 samples positive; gorillas, 3 of 4; long-tailed macaques, 14 of 16; spider monke ...200212438579
[the functional morphology of the large intestinal mucosa of the ox (bos primigenius f. taurus), sheep (ovis ammon f. aries) and goat (capra aegagrus f. hircus)].the mucous membrane of the large intestine of the ox, sheep and goat was studied using light and electron microscopy. the surface epithelium possesses the well-known complement of organelles with a conspicuous number of mitochondria as a source of energy for absorptive activities. occasionally, brush cells are found in the epithelium; the functional significance of this type of cell is still under discussion. in the present material, electron-lucid spheroids (diameter: 45 x 35 nm), which tend to ...200111379368
the effect of lactic acid on odour-related host preference of yellow fever mosquitoes.in a behavioural study we have investigated the role of lactic acid for the host preferences of yellow fever mosquitoes (aedes aegypti) by comparing the attractiveness of rubbings from the hands of different human individuals and extracts obtained from skin rubbings from different mammals (bos primigenius f. taurus, capra aegagrus f. hircus, felis silvestris f. catus and homo sapiens). certain human individuals were consistently more attractive to mosquitoes than others. addition of lactic acid ...200111418498
genetic evidence for near-eastern origins of european cattle.the limited ranges of the wild progenitors of many of the primary european domestic species point to their origins further east in anatolia or the fertile crescent. the wild ox (bos primigenius), however, ranged widely and it is unknown whether it was domesticated within europe as one feature of a local contribution to the farming economy. here we examine mitochondrial dna control-region sequence variation from 392 extant animals sampled from europe, africa and the near east, and compare this wi ...200111323670
[dna fingerprinting and genetic diversity of the european bison (bison bonasus), american bison (bison bison), and gray ukrainian cattle (bos taurus)].to describe genetic variability and population diversity in domesticated populations of american bison (bison bison), aurochs (bison bonasus), and gray ukrainian cattle (bos taurus) different variants of dna fingerprinting technique (utilizing the m13 phage dna, (ttaggg)4 synthetic oligonucleotide, and three arbitrary primers as hybridization probes) were used. several parameters characterizing polymorphism and genetic diversity levels in each population (species) were evaluated on the basis of ...200011094772
[dna-fingerprinting of representatives of bovinae subfamilies using the telomere markers (ttaggg)4].the (ttaggg)4 oligonucleotide homologous to telomeric tandem repeats of human chromosomes was used for the first time as a multilocus hybridization probe for the analysis of genome variability in the two genera (bos and bison) of the bovinae subfamily. dna profiles for cattle, banteng, aurochs, and bison were obtained. hybridization spectra were represented by the discrete individual- and species-specific bands characterized by codominant inheritance. for comparison, dna profiles of the same sam ...199910330618
[morphogenesis of the submucosal gland of cattle (bos primigenius f. taurus)].in the 10th week of gestation the development of duodenal glands in the bovine intestinum starts by circumscript epithelial proliferation. their secretory channels are in contact with the crypts. already in the early fetal stage ultrastructurally there are an inconspicuous equipment with organelles in the apical cytoplasm and single globular granules, which demonstrate the differentiation of epithelial cells into duodenal glandular cells. until the mid-point of the pregnancy the granular endopla ...199910208027
the morphology and cell structure of some nuclei in tuberal region of bison bonasus.the topography, shape and cell structure of the ventromedial, dorsomedial and infundibular nuclei in aurochs hypothalamus were studied on the basis of standard histological preparations. these nuclei are uniform cell bands. nucleus infundibularis is the longest centre in tuberal region and enter the mamillary area. its posterior part has maximum size. the ventromedial nucleus is outlined and developed best. it is typical ring-shaped in anterior half of its length. the dorsomedial nucleus is deve ...199810437307
[prenatal development of the lamina epithelialis in the phase of vacuolization of villous epithelial cells. investigations on the intestines of cattle (bos primigenius taurus l., 1758)].the development of the bovine small intestine was examined in 39 embryos and fetuses by light microscopic and transmission electron microscopic methods. special reference was paid to the histogenesis of the ephithelium. in contrast to the duodenum the epithelium of jejunum and ileum undergoes a degeneration by vacuolation of its villous epithelial cells. the demonstration of the acid phosphatase activity of these vacuoles shows their lysosomal character. this degenerative process of the small in ...19989972643
[early fetal development of the small intestine mucosa in cattle (bos primigenius taurus)].the development of the bovine small intestine was examined in 24 embryos and fetuses by light microscopic, scanning and transmission electron microscopic methods. special reference was paid to the genesis of the epithelium and particularly of the villi intestinales. the primitive intestine consists of one layer of epithelial cells surrounded by mesenchym and tunica serosa. the fetal intestine (up to the 24th week of gestation) shows all the morphologic structures of the adult. in small intestine ...19989818454
mitochondrial dna variation and evolution of japanese black cattle (bos taurus).this article describes complete mitochondrial dna displacement loop sequences from 32 japanese black cattle and the analysis of these data in conjunction with previously published sequences from african, european, and indian subjects. the origins of north east asian domesticated cattle are unclear. the earliest domestic cattle in the region were bos taurus and may have been domesticated from local wild cattle (aurochsen; b. primigenius), or perhaps had an origin in migrants from the early domest ...19989799268
[the characteristics of the reproductive capacity of hybrids of the bison (bison bison l.) with the domestic cow (bos (bos) primigenius taurus). the reproductive capacity of hybrid females].reproduction ability of hybrid females received in various variants of absorbent and variable crossing of bison and domestic cow has been studied. normal development of genitals, oogenesis, display of sexual activity, as well as fertilization have been found in all females, independently of their blood content. frequent cases of "relative" sterility in some females of the i-iii generations have immunological character and are predominantly caused by the mortality of embryos and fetuses at variou ...19979381557
ancient dna suggests a recent expansion of european cattle from a diverse wild progenitor species.a total of 11 bos primigenius and bos taurus bones from archaeological sites between 500 and 12000 years old were examined for the presence of dna. it was possible to amplify and sequence mitochondrial control region dna extracted from seven of the 11 samples, including two pleistocene b. primigenius samples. we compared the results with published data by constructing phylogenetic networks. the two b. primigenius samples clustered with the extant b. taurus samples in the networks. the similarity ...19968952089
the horizontal cells of artiodactyl retinae: a comparison with cajal's descriptions.the morphology of horizontal cells in ox, sheep, and pig retinae as observed after lucifer yellow injections are described and compared with the descriptions of golgi-stained cells by ramón y cajal (1893). horizontal cells in the retinae of less domesticated species, wild pig, fallow and sika deer, mouflon, and aurochs were also examined. all these retinae have two types of horizontal cell; their morphologies are in common, although with some familial differences. their basic appearance is as ca ...19968870229
constitutive amplification of a zinc finger protein gene in cattle.the human ozf gene encodes a protein consisting essentially of zinc finger motifs of the krüppel type. evolutionary studies revealed amplification of the bovine ozf gene in cattle. domestic cattle includes two major subspecies: taurine (bos primigenius taurus) and zebu (b. p. indicus). amplified sequences were found in both subspecies and mapped to the same locus of chromosome x in band q11. no amplification was found in other bovids and in particular in bison, the closest related genus to the g ...19968561900
mitochondrial diversity and the origins of african and european cattle.the nature of domestic cattle origins in africa are unclear as archaeological data are relatively sparse. the earliest domesticates were humpless, or bos taurus, in morphology and may have shared a common origin with the ancestors of european cattle in the near east. alternatively, local strains of the wild ox, the aurochs, may have been adopted by peoples in either continent either before or after cultural influence from the levant. this study examines mitochondrial dna displacement loop sequen ...19968643540
extensive mhc class ii drb3 diversity in african and european cattle.genetic diversity at the highly polymorphic bola-drb3 locus was investigated by dna sequence analyses of 18 african cattle from two breeds representing the two subspecies of cattle, bos primigenius indicus and bos primigenius taurus. the polymorphism was compared with that found in a sample of 32 european cattle from four breeds, all classified as b. p. taurus. particularly extensive genetic diversity was found among african cattle, in which as many as 18 alleles were recognized in this small ra ...19957590975
[blood group polymorphism in bison (bison bonasus)].polymorphism of nine blood group systems was studied in three reproductive lines of auroch (european bison bison bonasus), belovezhskaya, caucasian-belovezhskaya, and gornaya. all blood group systems analyzed were polymorphic; 50 out of the 57 antigens tested were detected. the number of detected blood group antigens in aurochs is comparable to that in breeds of domestic cattle. however, intrapopulation diversity, estimated with the mu test, is significantly higher in cattle than in aurochs. the ...19957896131
structure and topography of the nuclei of mamillary region in the bison bonasus.studies were carried out on the brains of two aurochs. the paraffin cross-sections 15 microns thick were stained according to nissl and klüver and barrera methods. in regio mamillaris were described two mamillary nuclei and two paramamillary nuclei. nucleus mamillaris lateralis and nucleus supramamillaris are uniform cellular bands while the nucleus mamillaris medialis and nucleus tuberomamillaris pars posterior consist of subdivisions. thopography of these centers in aurochs is similar to other ...19958606028
changes in some properties of the aurochs heart pyruvate dehydrogenase complex induced by its partial phosphorylation.comparative studies on the properties of the dephosphorylated and partially phosphorylated (to 35% activity reduction) pyruvate dehydrogenase complex (pdc) from aurochs heart muscle have been made. data have been obtained indicating that the partial phosphorylation of pdc abolishes the kinetic attributes of a positive cooperativity of the pyruvate binding sites (nh = 1.5) featuring at low substrate concentrations. in addition, the partially phosphorylated pdc is inactivated slower at 50 degrees ...19958592780
an investigation of the kinase activity of aurochs heart pyruvate dehydrogenase complex.the purified aurochs heart pyruvate dehydrogenase complex (pdc) saturated to approximation 60% with endogenous thiamine pyrophosphate (tpp), was slowly and incompletely inactivated by its kinase in the presence of atp. exogenous tpp or adp, but not pyruvate, strongly inhibited the kinase activity. the kinetic properties of the aurochs heart pdc kinase suggested the occurrence of two active sites each with different affinities for atp (k'm - 1.7 microm, k''m = 48 microm).19958673014
[the characteristics of the reproductive capacity of hybrids of the bison (bison bison l.) with the domestic cow (bos (bos) primigenius taurus). 1. the reproductive capacity of hybrid males].the hybrid progeny f1 produced by intergeneric crosses of a bison with a domestic cow is characterized by absolute sterility of the male line and fertility of the female line. crossing of females with fertile males of initial forms permits us to obtain fertile males in the following generations. any differences in stabilization of spermatogenesis in hybrid males obtained from various crosses and under selection of parental couples were not detected.19957676511
some toxic and trace metals in big game hunted in the northern part of poland in 1987-1991.game animal meats (muscle, liver and kidneys) collected from different regions in northern part of poland in 1987-1991 were analysed for mercury, cadmium, lead, copper, manganese, zinc and iron. toxic mercury, cadmium and lead occurred in relatively low concentrations in muscle and organ meats, with the exception of lead in muscle and cadmium in kidneys, which were relatively more contaminated. the concentrations of essential trace metals in samples examined seemed to be natural. roe-deer contai ...19948178124
evidence for two independent domestications of cattle.the origin and taxonomic status of domesticated cattle are controversial. zebu and taurine breeds are differentiated primarily by the presence or absence of a hump and have been recognized as separate species (bos indicus and bos taurus). however, the most widely held view is that both types of cattle derive from a single domestication event 8000-10,000 years ago. we have examined mtdna sequences from representatives of six european (taurine) breeds, three indian (zebu) breeds, and four african ...19948146187
basic properties of the pyruvate dehydrogenase complex isolated from aurochs heart.the purified aurochs (bison bonasus, european bison) heart pyruvate dehydrogenase complex (pdc) has a set of subunits typical of mammalian pdc. pdc from aurochs heart contains firmly bound tiamine pyrophosphate in the amount providing over 50% of the maximal activity of the complex. the apparent value for activation energy of pdc is 60 kj/mol. the michaelis constant values for aurochs heart pdc are 22.4 +/- 1.0, 3.3 +/- 0.1 and 24.4 +/- 3.6 microm for pyruvate, coa and nad, accordingly. acetyl-c ...19947732764
allometric growth of spleen and liver in black-white bovine fetuses (bos primigenius f. taurus).growth relationships between spleen and liver weights and body weight and cr length as well as between weights of liver and spleen in fetuses (145 males, 141 females) of black-white cattle. according to their body weights, the fetuses were divided into 4 growth groups: i, to 1000 g; iia, 1000-3490 g; iib, 3500-7990 g; iii, over 8000 g. the relationships were described using appropriate allometric growth equations (log y = b log x + a) derived both for individual groups and for the entire fetal p ...199310187988
[the characteristics of the reproductive capacity of hybrids of banteng (bos (bibos) javanicus d'alton) with the domestic cow (bos (bos) primigenius taurus)].the hybrid progeny of f1 produced by crossing of banteng and domestic cow is characterized by absolute sterility of the male line and fertility of the female line. the crossbred males become fertile in further progenies while crossing cross-females with males of initial forms. successful use of inter-subgenetic hybrids of banteng and domestic cow in selection work is hindered by pathological deviations in their genitals structure as well as frequent deaths of the embryos and foetus in hybrid cow ...19921292161
prenatal growth and asymmetry of thyroid gland in the cattle (bos primigenius f. taurus).growth and bilateral asymmetry of thyroid gland were studied in 291 fetuses (from 219 to 31,300 g) of the black-white cattle divided into 4 groups according to body weight. relation between body weight (x) and thyroid weight (y) was described using allometric equation y = axb. allometric coefficient b was different in each of the four groups (1.198; 1.179; 1.314; 0.941) and amounted to 1.076 for the entire fetal period. the coefficient of fluctuating asymmetry of the thyroid gland decreased with ...19921339565
[an unusual case of chronic fibrosing endometritis and mucometra in a watusi cow (bos primigenius f. taurus) with uterine foreign bodies].genital organs, ureter, urinary bladder, and blood were collected from a 12 year old watusi cow which never exhibited estrous behaviour. post-mortem findings and hormone assays, however, indicated the incidence of recent estrous cycles. the animal showed a chronic panmetritis, retained fetal membranes or fetal residues, an infected mucometra with cystic glandular hyperplasia, and a leiomyoma. tubular genitalia, ureter, and urinary bladder exhibited subacute inflammation.19911914949
[the cytomorphology of goblet cells of the fetal intestine. studies of the large intestine of cattle (bos primigenius taurus)].in the region of the base of the intestinal crypts undifferentiated goblet cells display a configuration and constellation of organelles and membrane structures that are indicative of their importance for function. these images at this stage of development deliver a scenario of the mechanism of secretory granule production: aggregates of protein vesicles from the "transitional elements" (palade) of the granular endoplasmic reticulum are, so to speak, rolled up on the trans side of the golgi appa ...19902096533
[endocrine cells in the epithelium of the fetal large intestine of cattle (bos primigenius taurus) from the cytomorphological aspect].in the epithelium of the fetal bovine large intestine there are endocrine cells, predominantly at the base of the crypts. according to morphological characteristics, ec-cells and l-cells can be readily distinguished.19902403209
[expression of genes controlling modification of amylase in hybrids and original representatives of a cattle subfamily (bovinae)].modifications of similar type were noted in the number of multiple amy-1 forms of amylase isozyme for various species of artiodactyla. it is supposed that these modifications are linked to periodical activation during evolution of genes responsible for modification of the molecules. data obtained on bovinae hybrids testify to this point of view. inactivation of active and reinactivation of "silent" genes responsible for modification of amy-1 molecules are observed in hybrids of bison x cow and b ...19901706678
innervation pattern in jaw muscles of various mammalian chewing types.the intramuscular nerve branches of the masticatory muscles were investigated in different mammalian species such as canis familiaris, capreolus capreolus, capra hircus africans, bos primigenius forma taurus, myocastor coypus molina 1782, sus scrofa domestica, pan troglodytes, homo sapiens. the ramifications of the nerves form a specific pattern that is adapted to the specialised muscle structures in all mammalian chewing type. the innervation pattern is fully consistent with the infrastructures ...19892816526
