scanning electron microscopic observations on the development and structure of tooth enamel in cervidae (mammalia: ruminantia).enamel formation and structure were investigated in 102 developing or erupted teeth of roe, fallow and red deer. special attention was given to the topography of the forming enamel surface, the form, arrangement and course of enamel rods, its relation to interprismatic enamel and the occurrence of hunter-schreger-bands in the enamel. discussed are the significance of the enamel pattern for the identification of certain taxa and the adaptive value of cervidean enamel structures.19911759724
spiculopteragia spiculoptera, s. asymmetrica and ostertagia leptospicularis from cervus elaphus in la pampa, argentina.the nematode species spiculopteragia spiculoptera, spiculopteragia asymmetrica and ostertagia leptospicularis were recovered from the abomasum of wild red deer, cervus elaphus, in the forest area of the semi-arid pampeana region of la pampa (argentina) for the first time. oesophagostomum venulosum and dictyocaulus spp. were also found.19911763487
erg, an ets-related gene, codes for sequence-specific transcriptional activators.e26 is a replication-defective avian acute leukemia virus which causes erythroblastosis and myeloblastosis in chickens. it carries two distinct oncogenes, v-myb and v-ets, both of which contribute to its transforming properties. several genes related to the ets oncogene (c-ets-1, ets-2, erg, elk-1, elk-2, pu.1/spi-1, e74 and fli-1) have been described. previously we have shown that the erg gene (ets-related gene) codes for at least two proteins (erg-1 and erg-2) because of alternative splicing a ...19911766675
mycobacterium bovis infection in human beings in contact with elk (cervus elaphus) in alberta, canada.human infection with mycobacterium bovis is rare in developed countries because of milk pasteurisation and the slaughter of infected cattle. an epizootic of m bovis infection in domesticated elk (cervus elaphus) in alberta, canada, which started in april, 1990, prompted us to seek human contacts of elk herds. there were 446 identified contacts, in 394 of whom tuberculin skin tests were done. of 81 contacts who were skin-test positive, 50 had been in contact with culture-positive animals. 6 of 10 ...19911682654
the biochemical systematics of red and sika deer (genus cervus) in ireland.twenty enzyme loci were investigated using starch gel electrophoresis in managed populations of red deer (cervus elaphus) and sika deer (c. nippon) from ireland. the red deer, which originated from several european countries, were polymorphic (%p) at 25% of the loci examined and exhibited a mean heterozygosity (h) of 0.025. the sika, originally from japan, were introduced to ireland in very limited numbers. here, %p was 5% and h was 0.006. mean genetic distance (d) between these taxa was 0.160. ...19911816170
transferrin polymorphism and genetic differentiation in cervus elaphus l. (european red deer) populations.a study of transferrin in 11 different european populations of cervus elaphus as well as in one cervus elephus x cervus nippon hybrid population has revealed a polymorphism of this protein. genetic analysis suggests that it is controlled by one gene locus with three codominant alleles. the allele frequencies allow a clear discrimination not only between the hybrid population and pure red deer but also between different continental red deer populations. comparison of the genotypic structures with ...19911757275
[pathologic changes in the lungs of deer spontaneously infected with nematodes from the protostrongylidae family].lungs of 30 animals of the red deer (cervus elaphus hippelaphus) attacked by parasitic helminths were submitted to a histological examination, and the changes which were caused by the nematodes of protostrongylidae family were estimated. the lungworm varestrongylus sagittatus (mueller, 1891) creates hatching tubercles of a dark-red or yellow-green and even ochre colour. the lobular catarrhal bronchopneumonia is a histological correlate. in hatching tubercles there are located adult nematodes, ov ...19911771735
temporal changes in lh and testosterone and their relationship with the first antler in red deer (cervus elaphus) stags from 3 to 15 months of age.blood samples were taken from six tame red deer stags at 3-15 months of age once a month from a jugular catheter every 30 min for 24 h to investigate hormonal secretion during puberty and during growth of the pedicle and first antler. all plasma samples were analysed for lh and testosterone concentrations and the resultant data were analysed using the pulsar pulse detection routine. in addition each stag was injected wih gonadotrophin-releasing hormone (gnrh; 20 ng/kg body weight) after the abov ...19911783890
lipoptena cervi (diptera), a potential vector of megatrypanum trypanosomes of deer (cervidae).in three different areas in northern germany, hippoboscids were collected from red deer (cervus elaphus). typanosomatids were demonstrated in the midgut and hindgut of 9/37 lipoptena cervi. the trypanosomatids were morphologically similar to vector forms of the subgenus megatrypanum that had been found in tabanids at the same location 5 years previously. hippoboscids are therefore potential vectors of trypanosoma (megatrypanum) spp. that infect red deer.19911805220
mycobacterium bovis infection in humans exposed to elk in alberta.the evidence of zoonotic transmission of m. bovis infection in the 1 veterinarian is confirmed by growth of the organism from his sputum 6 months after animal contact. the high rate of initial tuberculin reactivity and the skin test conversions of 6 persons in contact with culture-positive animals strongly suggest that further human infection has taken place. however, the lack of baseline testing on 48/81 test-positive individuals and the relatively high proportion of immigrants in some occupati ...19911841004
evaluation of relationship between plasma fibrinogen concentration and tuberculin testing in red deer.after intradermal injection of bovine purified derivative (ppd), increases in plasma fibrinogen concentration and plasma viscosity developed in red deer (cervus elaphus) with a history of tuberculosis caused by mycobacterium bovis. serum haptoglobin concentrations were also found to increase under similar circumstances. the increases were reproducible and did not appear to be related to mustering, stress, or the handling associated with injection of ppd. a significant (p less than 0.05) direct r ...19912071482
characterization of elk, a brain-specific receptor tyrosine kinase.the elk gene encodes a novel receptorlike protein-tyrosine kinase, which belongs to the eph subfamily. we have previously identified a partial cdna encompassing the elk catalytic domain (k. letwin, s.-p. yee, and t. pawson, oncogene 3:621-678, 1988). using this cdna as a probe, we have isolated cdnas spanning the entire rat elk coding sequence. the predicted elk protein contains all the hallmarks of a receptor tyrosine kinase, including an n-terminal signal sequence, a cysteine-rich extracellula ...19912017163
spatial variability in the nutrient composition of populus tremuloides: clone-to-clone differences and implications for cervids.populus tremuloides, a clonal angiosperm, is a major food item for many temperate-region herbivores. clonal variation in chemical composition has potentially important implications for vertebrate herbivores because a single clone may be areally large and hence, may comprise a large part of available forage. the objectives of this study were: (1) to examine spatial variability in nutrient concentrations and quality within and among 24 clones of trembling aspen, and (2) to evaluate these differenc ...199128312739
countervailing selection in different fitness components in female red individually monitored red deer (cervus elaphus) living in the north block of the isle of rhum, scotland, juvenile survival is related to the genotype at the enzyme loci mpi and idh-2 (each with two alleles, f and s). to establish whether other fitness components also are related to genetic differences, we examined whether age at first breeding, fecundity, and adult survival of females were related to genotype at the same loci. fertility in females shot outside the study area was also analyze ...199128564077

r51163 as a sedative for handling and transporting plains bison and wapiti.forty captive wapiti (cervus elaphus) and thirty-two bison (bison bison bison) were tested in april and october 1988, respectively, for their response to the sedative r51163. treatment animals were injected with either 0.1, 0.2, or 0.3 mg of r51163/kg and then observed for 72 hr. behavior was significantly altered by the drug. hyperactive, aggressive, and milling behavior was characteristic of treated wapiti and they were extremely dangerous and reared when hind quarters were touched. although t ...19921602574
a comparison of serological relationships among five ruminant alphaherpesviruses by elisa.using enzyme-linked immunosorbent assays the cross reactivity of bovine herpesvirus-1.1, bovine herpesvirus-1.2, caprine herpesvirus-2, cervine (red deer) herpesvirus-1 and rangiferine (reindeer) herpesvirus-1 has been examined using rabbit hyperimmune antisera and convalescent cattle and red deer field sera. significant cross-reactivity among all the five viruses was demonstrated. a detailed analysis showed that: (1) the two bovine herpesviruses are most closely related, (2) the cervine, caprin ...19921605741
[spongiform encephalopathies with special reference to bovine spongiform encephalopathy].in switzerland bovine spongiform encephalopathy (bse) was detected for the first time in november 1990. it is a transmissible disease of the central nervous system similar to creutzfeldt-jakob disease (cjd), gerstmann-sträussler-scheinker syndrome (gss) and kuru in man, and, in animals, scrapie in sheep and goats, chronic wasting disease (cwd) in captive mule deer and elk of north america and transmissible mink encephalopathy (tme) of farm reared mink. the infectious agent of the spongiform ence ...19921615298
elk-1 protein domains required for direct and srf-assisted dna-binding.the ets-related elk-1 protein can bind to purine-rich dna target sites in a sequence specific fashion and, in addition, can form a ternary complex with the c-fos serum response element (sre) and the serum response factor (srf). we demonstrate that elk-1 can readily interchange between its different interaction partners. the amino terminal ets-domain of elk-1 was shown to be necessary and sufficient for direct dna-binding activity. for ternary complex formation with the sre and srf, both the elk- ...19921630903
spatial flexibility in ternary complexes between srf and its accessory proteins.we investigated the sequence requirements for ternary complex formation by the transcription factor srf and its ets domain accessory factors elk-1 and sap-1. ternary complex formation is specified by an srf consensus site cc(a/t)6gg and a neighbouring ets motif (c/a)(c/a)gga(a/t), which is contacted by elk-1/sap-1. both the spacing of these sequences and their relative orientation can be substantially altered with little effect on the efficiency of ternary complex formation. efficient ternary co ...19921425594
purification, partial characterization, and heterologous radioimmunoassay of growth hormone (cgh) in red deer growth hormone (cgh; 3.3 mg) was purified from an aqueous extract of seven pituitary glands (4.01 g wet weight) by preparative gel filtration on sephadex g-100, gel filtration on sephadex g-100 sf, and anion exchange chromatography on deae-sepharose cl-6b. purified cgh gave a single band on sodium dodecyl sulfate-polyacrylamide gel electrophoresis with a molecular weight under reducing conditions of 20,000 da and gave a single peak on reverse-phase high-performance liquid chromatography ...19921426952
affinity purification of histidine-tagged proteins transiently produced in hela order to produce eukaryotic proteins in a functional state, it is often necessary to use eukaryotic instead of prokaryotic expression systems. we have designed vectors which can be employed to express either n- or c-terminally histidine-tagged proteins in transiently transfected eukaryotic cells. the histidine tag allows the rapid enrichment of these proteins by metal chelate affinity chromatography in a native and functional state. yields of up to 5 micrograms protein/5 x 10(7) cells were ac ...19921446830
mycobacterium bovis infection in north american elk (cervus elaphus).a naturally occurring outbreak of mycobacterium bovis infection in captive wild elk (wapiti) in montana was confirmed by mycobacteriologic examination. twenty-eight of 143 elk responded to m. bovis purified protein derivative (ppd) tuberculin injected intradermally in the cervical region (sct). the results of comparative cervical tuberculin skin tests conducted within 9 days of sct revealed greater responses to m. bovis ppd tuberculin than to m. avium ppd tuberculin in 23 of 28 elk responding. a ...19921457545
gross and microscopic lesions of naturally occurring tuberculosis in a captive herd of wapiti (cervus elaphus nelsoni) in colorado.a mycobacterium bovis-infected herd of captive wapiti (cervus elaphus nelsoni) in colorado was depopulated after lesions of bovine tuberculosis were confirmed in 8 of 10 tuberculin skin test reactors. of the 43 animals > 1 year of age, 26 had gross lesions suggestive of tuberculosis, 24 had microscopic lesions of tuberculosis, and 23 had acid-fast bacilli associated with the lesions. lungs and retropharyngeal lymph nodes were the most frequently affected sites. most lesions grossly and microscop ...19921457546
