in search of virus carriers of the 1988 and 2002 phocine distemper virus outbreaks in european harbour seals.european harbour seal (phoca vitulina) populations decreased substantially during the phocine distemper virus (pdv) outbreaks of 1988 and 2002. different hypotheses have stated that various seals and terrestrial carnivore species might be the source of infection. to further analyse these hypotheses, grey (halichoerus grypus) and ringed (phoca hispida) seals, polar bears (ursus maritimus) and minks (mustela lutreola) were sampled from the north sea and east greenland coasts between 1988 and 2004 ...200817896075
prevalence of antibody to aleutian mink disease virus in european mink (mustela lutreola) and american mink (neovison vison) in spain.the european mink (mustela lutreola) has undergone a dramatic decline and is one of the most endangered mammals in the world. the invasive american mink (neovison vison) is considered the main factor for this decline. however, the american mink's introduction and the subsequent ecological concurrence of the two species cannot solely explain the decline or disappearance of the european mink. aleutian mink disease virus (amdv) is the main health problem in fur farming worldwide, causing varied cli ...201626528576
molecular epidemiology of aleutian mink disease virus (amdv) in estonia, and a global phylogeny of amdv.aleutian mink disease virus (amdv) causes a severe disease called aleutian disease (ad). amdv infects primarily mustelids, but also other mammal species. recent evidence suggests that amdv may also affect humans. to examine amdv in different wild animals and in farmed mink in estonia, we collected 203 blood samples from eight mammal species in 2007-2010, of which 152 were from species living in the wild (american mink, european mink, pine marten, polecat, raccoon dog, badger, otter, and stone ma ...201525616049
aleutian mink disease parvovirus in wild riparian carnivores in spain.serious declines in populations of native european mink (mustela lutreola) have occurred in europe. one responsible factor may be infectious diseases introduced by exotic american mink (mustela vison). in order to investigate a possible role for aleutian mink disease parvovirus (adv), we surveyed native riparian carnivores and feral american mink. when serum samples from 12 free-ranging european and 16 feral american mink were tested, antibodies to adv were detected from three of nine european m ...200111272488
an unusual case of spinal cord restricted mycobacteriosis in a european mink.granulomatous myelitis due to infection with mycobacterium avium was diagnosed in a 4-year-old male neutered european mink (mustela lutreola). the causative agent was detected by an acid-fast stain and further characterized by polymerase chain reaction and dna sequencing of the pcr product. a thorough histological evaluation of the remaining organs revealed no granulomatous lesions or detectable acid-fast organisms. although minks are generally highly susceptible for mycobacteria, localised infe ...201323403790
evidence for widespread leishmania infantum infection among wild carnivores in l. infantum periendemic northern spain.leishmania spp. infection was investigated in tissue samples of wild carnivores from the spanish basque country (bc), by pcr and dna sequencing. the region is at the northern periphery of leishmania infantum endemic iberian peninsula and infection in the dog (reservoir) or other species has not been previously reported. leishmania kinetoplast dna was detected by real-time pcr (rtpcr) in 28% (44/156) of animals. specifically, in 26% of eurasian badgers (n=53), 29% of foxes (n=48), 29% of stone ma ...201424380572
first report of filaria martis gmelin, 1790 in the european mink, mustela lutreola (linnaeus, 1761).the riparian european mink (mustela lutreola), currently surviving in only three unconnected sites in europe, is now listed as a critically endangered species according to the iucn. habitat loss and degradation, anthropic mortality, interaction with the feral american mink (neovison vison), and infectious diseases are among the principal causes of its decline. surveys of helminth parasites of this host that also include focus on subcutaneous potentially pathogenic helminths such as those belongi ...201627008189

fatal acinetobacter baumannii infection in the critically endangered european mink (mustela lutreola).the present study reports the first case of fatal acinetobacter baumannii infection in the critically endangered european mink ( mustela lutreola ). gross examination revealed a severe, diffuse hemorrhagic pneumonia and generalized congestion as main features. microscopically, the main lesions were an acute, severe fibrinous-hemorrhagic pneumonia associated with proliferation of coccobacilli and generalized acute-subacute congestion. cultures yielded a. baumannii ; the species was confirmed by m ...201728363063
[comparative substrate-inhibitor analysis of liver monoamine oxidases of minks].comparative substrate-inhibitor analysis of catalytic properties of liver monoamine oxidases (mao) was performed in the mature males of the american mink mustela vison and the european mink mustela lutreola. the action on the mao activity was studied of alkaloids of the benzo[c]phenanthridine group: sanguinarine and chelidonine, diisoquinoline alkaloid berberine, medication agents ukrain and sanguirythrin as well as derivatives of 2-propylamine: deprenyl and clorgylin. the latter turned out to b ...201021061647
[reproductive physiology of the european mink: progesterone profile during pregnancy].reproductive physiology of the european mink, an endangered mustelid species, has been so far scarcely investigated. this study confirms that in european mink embryo implantation occurs on the day 12 of pregnancy. progesterone profile during pregnancy has been compared in european mink and domestic ferret. in both species, progesterone increases at peri-implantation period, i. e. on day 8 and day 12 after mating. however, toward the end of pregnancy, on day 40 after mating, progesterone concentr ...201020564957
bayesian analysis of hybridization and introgression between the endangered european mink (mustela lutreola) and the polecat (mustela putorius).human-mediated global change will probably increase the rates of natural hybridization and genetic introgression between closely related species, and this will have major implications for conservation of the taxa involved. in this study, we analyse both mitochondrial and nuclear data to characterize ongoing hybridization and genetic introgression between two sympatric sister species of mustelids, the endangered european mink (mustela lutreola) and the more abundant polecat (m. putorius). a total ...201121244536
helminth communities of the autochthonous mustelids mustela lutreola and m. putorius and the introduced mustela vison in south-western france.this study presents the first comprehensive helminthological data on three sympatric riparian mustelids (the european mink mustela lutreola, the polecat m. putorius and the american mink m. vison) in south-western france. one hundred and twenty-four specimens (45 m. lutreola, 37 m. putorius and 42 m. vison) from eight french departments were analysed. globally, 15 helminth species were detected: troglotrema acutum, pseudamphistomum truncatum, euryhelmis squamula, euparyphium melis and ascocotyle ...200818752724
[ecori- and bamhi-families of repeated sequences in mustelids].the restriction enzymes ecori and bamhi digest the genomic dnas from six mustelids species mustela lutreola, m. vision, m. erminea, m. sibirica, vormela peregusna, producing repeated fragments varying in length. some fragments were hybridized to chromosomes and restriction digests of dnas from some mustelids and other mammals. the 0.7 kb ecori repeats from dna of m. erminea are dispersed over chromosomes of carnivors. the 1.35, 1.9 and 2.7 kb bamhi repeats from dna of polecat m. putorius furo ar ...20082583487

cloned ferrets produced by somatic cell nuclear transfer.somatic cell nuclear transfer (scnt) offers great potential for developing better animal models of human disease. the domestic ferret (mustela putorius furo) is an ideal animal model for influenza infections and potentially other human respiratory diseases such as cystic fibrosis, where mouse models have failed to reproduce the human disease phenotype. here, we report the successful production of live cloned, reproductively competent, ferrets using species-specific scnt methodologies. critical t ...200616584722
intrageneric diversity of the cytochrome b gene and phylogeny of eurasian species of the genus mustela (mustelidae, carnivora).to illuminate molecular phylogenetic relationships among eurasian species of the genus mustela (mustelidae, carnivora), we determined nucleotide sequences of the complete mitochondrial cytochrome b gene region (1,140 base pairs). molecular phylogenetic trees, constructed using the neighbor-joining and the maximum likelihood methods, showed the common topology of species relationships to each other. the american mink m. vison first branched off and was positioned very remotely from the other spec ...200018517304
from aquatic to terrestrial food webs: decrease of the docosahexaenoic acid/linoleic acid ratio.fatty acid composition of the adipose tissue of six carnivorous mammalian species (european otter lutra lutra, american mink mustela vison, european mink mustela lutreola, european polecat mustela putorius, stone marten martes foina and european wild cat felis silvestris) was studied. these species forage to differing degrees in aquatic and terrestrial food webs. fatty acid analysis revealed significant differences in polyunsaturated fatty acid composition between species. more specifically, our ...200818335265
factors affecting the efficiency of embryo transfer in the domestic ferret (mustela putorius furo).embryo transfer (et) to recipient females is a foundational strategy for a number of assisted reproductive technologies, including cloning by somatic cell nuclear transfer. in an attempt to develop efficient et in domestic ferrets, factors affecting development of transferred embryo were investigated. unilateral and bilateral transfer of zygotes or blastocysts in the oviduct or uterus was evaluated in recipient nulliparous or primiparous females. developing fetuses were collected from recipient ...200616330092
aleutian disease serology, protein electrophoresis, and pathology of the european mink (mustela lutreola) from navarra, spain.the european mink, mustela lutreola, has suffered a dramatic decline in europe during the 20th century and is one of the most endangered carnivores in the world. the subpopulation of european mink from navarra, spain, estimated to number approximately 420, represents approximately two thirds of the total number of mink in spain. aleutian disease virus (adv) is a parvovirus with a high degree of variability that can infect a broad range of mustelid hosts. the pathogenesis of this virus in small c ...200818816991
patterns of genetic variation in the endangered european mink (mustela lutreola l., 1761).the european mink (mustela lutreola, l. 1761) is a critically endangered mustelid, which inhabits several main river drainages in europe. here, we assess the genetic variation of existing populations of this species, including new sampling sites and additional molecular markers (newly developed microsatellite loci specific to european mink) as compared to previous studies. probabilistic analyses were used to examine genetic structure within and between existing populations, and to infer phylogeo ...201526183103
antibodies to aleutian mink disease parvovirus in free-ranging european mink (mustela lutreola) and other small carnivores from southwestern france.owing to the rapid decline of the european mink (mustela lutreola) in france, a national conservation action plan has been initiated, in which scientific research to improve understanding of the causes of the decline is one of the primary objectives. in order to investigate the possible role of aleutian disease parvovirus (adv) in decline of the species, a serologic survey was conducted from march 1996 to march 2002 in 420 free-ranging individuals of six species of small carnivores distributed i ...200415465705
situation and context impacts the expression of personality: the influence of breeding season and test context.non-human animal personality is defined as consistent behavioural differences across time and situations/contexts. behaviours are, however, often plastic and to explain how plasticity and personality may coexist an adaptive framework has been developed. still, there is little information on how personality is impacted by situations and contexts on an individual level. we investigated this in the european mink (mustela lutreola) by performing a set of five experiments in two situations consisting ...201323988476
conservation genetics and population history of the threatened european mink mustela lutreola, with an emphasis on the west european population.in species of great conservation concern, special attention must be paid to their phylogeography, in particular the origin of animals for captive breeding and reintroduction. the endangered european mink lives now in at least three well-separated populations in northeast, southeast and west europe. our aim is to assess the genetic structure of these populations to identify 'distinct population segments' (dps) and advise captive breeding programmes. first, the mtdna control region was completely ...200515969721
vaccine-induced canine distemper in european mink, mustela lutreola.this report describes vaccine-induced canine distemper virus (cdv) infection in four european mink (mustela lutreola) induced by the administration of a multivalent, avian-origin vaccine. clinical signs consisting of seizures, ataxia, facial twitching, oculonasal discharge, hyperkeratosis of footpads, and anorexia developed 16-20 days postvaccination. conjunctival smears from one animal were positive for cdv antigen by direct fluorescent antibody testing, confirming the clinical diagnosis. the f ...19979365945
an electrophoretic investigation of mammalian spermatid-specific nuclear proteins.using standardized methods for protein extraction and analysis, the testes of rams, bulls, goats, boars, stallions, rats, cats, hedgehogs, european mink and ferrets were examined for basic spermatid nucleoproteins by electrophoresis. the results suggest that differences exist in the total number of these proteins as well as in the number and amount of the cross-linked cystein-containing proteins. these differences appear to be more family-specific than species-specific.19827077593
evidence of secondary poisoning of free-ranging riparian mustelids by anticoagulant rodenticides in france: implications for conservation of european mink (mustela lutreola).because of the rapid decline of the endangered european mink (mustela lutreola) populations in france, a national conservation program has been put into action, including research to understand the causes of decline. as part of this research, concentrations of eight anticoagulant rodenticides were examined in livers from 122 carcasses of four species of free-ranging mustelids collected between 1990 and 2002 in southwestern france. bromadiolone residue was found in all species and 9% of the sampl ...200415650086
environmentally enriched male mink gain more copulations than stereotypic, barren-reared competitors.wild carnivores in zoos, conservation breeding centres, and farms commonly live in relatively small, unstimulating enclosures. under these captive conditions, in a range of species including giant pandas, black-footed ferrets, and european mink, male reproductive abilities are often poor. such problems have long been hypothesized to be caused by these animals' housing conditions. we show for the first time that rearing under welfare-improving (i.e., highly valued and stress-reducing) environment ...201324282547
leptospirosis in free-ranging endangered european mink (mustela lutreola) and other small carnivores (mustelidae, viverridae) from southwestern france.to study the possible role of disease in the decline of endangered european mink (mustela lutreola), we conducted a survey of antibody prevalence and renal carriage of pathogenic leptospira (leptospira interrogans sensu lato) using serum and kidney samples collected from 1990 to 2007 from several free-ranging small carnivores and farmed american mink (mustela vison) in southwestern france. an indirect microscopic agglutination test using a panel of 16 serovars belonging to 6 serogroups (australi ...201020966265
serologic survey for selected viral pathogens in free-ranging endangered european mink (mustela lutreola) and other mustelids from south-western france.to investigate the possible role of selected pathogens in the decline of endangered european mink (mustela lutreola) populations and the potential for these pathogens to affect mink survival, a serologic survey was conducted using serum samples collected from march 1996 to march 2003 in eight departments of south-western france. in total, 481 free-ranging individuals of five mustelid species (including the european mink) were tested. sympatric mustelids can serve as sentinels to determine the pr ...200818957635

canine distemper of vaccine origin in european mink, mustela lutreola--a case report.cases of canine distemper (cd) related to vaccination of exotic carnivores extend over three decades and have been described in at least nine different species. our report describes a case of acute cd in a european mink, mustela lutreola, vaccinated with live attenuated cd vaccine licensed for use in fur-farmed mink. the male mink died of an acute grey matter disease with an unusually long incubation period. a female vaccinated at the same time showed no obvious signs of illness. the diagnosis w ...200312523990
reproductive parameters of critically endangered european mink (mustela lutreola) in captivity.founding captive populations is often the last chance for saving endangered species from extinction. ensuring successful reproduction is typically most critical for the maintenance of captive populations, with purposeful selection of individuals for breeding being one of the crucial aspects. comparable cross-species data on the determinants of reproduction success are most useful for solving problems in captive species programs. in the present study, we provide an overview of a 20-year captive b ...201728412080
the influence of spatiotemporal conditions and personality on survival in reintroductions-evolutionary implications.personality exists in non-human animals and can impact fitness. there is, however, a shortage of empirical studies in certain areas within the field, and fundamental evolutionary theory on personality remains largely untested. for example, little is known on how variation in personality is maintained over evolutionary time. theory suggests that fluctuating selection pressures due to spatiotemporal variation in conditions, e.g. food availability, is a possible mechanism and a few studies have sho ...201727722799
comparative molecular cytogenetic studies in the order carnivora: mapping chromosomal rearrangements onto the phylogenetic tree.we have made a set of chromosome-specific painting probes for the american mink by degenerate oligonucleotide primed-pcr (dop-pcr) amplification of flow-sorted chromosomes. the painting probes were used to delimit homologous chromosomal segments among human, red fox, dog, cat and eight species of the family mustelidae, including the european mink, steppe and forest polecats, least weasel, mountain weasel, japanese sable, striped polecat, and badger. based on the results of chromosome painting an ...200212438790
effects of environmental enrichment and stereotypic behavior on maternal behavior and infant viability in a model carnivore, the american mink (neovison vison).in several species, stress compromises maternal behaviors that are important for infant viability (e.g. licking and grooming). understanding how stress in captivity affects maternal behavior could therefore be beneficial, especially for carnivores in zoos and breeding centers where infant mortality is often high. we used a model carnivore--american mink--to test two hypotheses, namely that maternal investment and/or behavior is i. improved by environmental enrichment; and ii. compromised by ster ...201626536278
noninvasive monitoring of female reproductive hormone metabolites in the endangered european mink (mustela lutreola).this study examined the reproductive physiology of female european mink (mustela lutreola) to augment the available information on estrus, ovulation, and pregnancy with the long-term goal of supporting ex situ breeding management of this highly endangered species. fecal reproductive hormone metabolites were measured using eias for estrogen and 20-oxo-pregnane metabolites. seasonal hormone profiles were established. a comparison of hormone fluctuations in pregnant and nonpregnant females showed t ...201526324114
the causes of the low breeding success of european mink (mustela lutreola) in captivity.high among-individual variation in mating success often causes problems in conservation breeding programs. this is also the case for critically endangered european mink and may jeopardize the long-term maintenance of the species' genetic diversity under the european mink eep program. in this study, breeding success of wild and captive born european minks at tallinn zoological garden are compared, and the mating behavior of the males is analyzed. results show that wild born males successfully mat ...201323426800
mhc class ii variation in the endangered european mink mustela lutreola (l. 1761)--consequences for species conservation.the polymorphic major histocompatibility complex (mhc) has gained a specific relevance in pathogen resistance and mate choice. particularly the antigen-binding site (abs), encoded by exon 2 of the drb class ii gene, exhibits numerous alleles and extensive sequence variations between alleles. a lack of mhc variability has attributed to instances such as bottleneck effects or relaxed selection pressure and has a certain impact on the long-term viability of the species concerned. as a result of ser ...200919263000
cranial helminths of mustela vison schreber, 1777 in spain.a survey was carried out to investigate the presence of cranial helminths in 337 american minks (mustela vison) from spain. this information was obtained partly in order to evaluate potential conservation problems and sanitary risks to the congeneric european mink (mustela lutreola), one of the most endangered carnivores in the world. skulls and rectal faeces of each specimen were simultaneously analysed. troglotrema acutum and skrjabingylus nasicola were found in 5.6% of the m. vison analysed. ...200616490319

seroprevalence and b1 gene genotyping of toxoplasma gondii in farmed european mink in the republic of tatarstan, russia.toxoplasma gondii is a protozoan parasite that infects almost all species of mammals and birds, including fur-bearing animals. however, the prevalence of t. gondii among russian fur-bearing animals is unknown. in this study, the seroprevalence of t. gondii in european mink in russia was investigated. in total, 100, 119 and 61 serum samples were collected from a fur farm, located in the republic of tatarstan, russia, in autumn 2016, 2017 and 2018, respectively. the seroprevalence of t. gondii in ...202032004751
immobilization of free-ranging european mink (mustela lutreola) an polecat (mustela putorius) with medetomidine-ketamine and reversal by atipamezole.from march 1996 to august 1999, 24 free-ranging european mink (mustela lutreola) and 25 free-ranging polecats (mustela putorius) were immobilized for clinical procedures and to place radio transmitters. data were recorded during 14 and 12 trials, respectively. animals received intramuscularly 10 mg/kg ketamine (ket) combined with 0.20 mg/kg medetomidine (med), antagonized by 1.00 mg/kg atipamezole (ati). anesthesia times were similar between species. induction was smooth and rapid (0.7-3.9 min); ...200312910767
surgical transfer of in vivo produced farmed european polecat (mustela putorius) embryos.surgical embryo transfer of farmed european polecat (mustela putorius) was investigated as part of an ex situ preservation project. the long-term objective of the project is to develop effective technology for ex situ conservation of the european mink (mustela lutreola), which is a highly endangered aboriginal european species. twenty european polecat females, which served as a model species for the european mink, were humanely killed 4-9 days after first mating and embryos were recovered from o ...200212141567
molecular survey of genetic diversity in the endangered european mink mustela lutreola.the european mink mustela lutreola is regarded as one of the most endangered mammals in the world. we chose to characterize microsatellite loci in order to investigate the pattern of decline of this species. we used primer pairs developed for a related species mustela vison to genotype individual of mustela lutreola. out of 19 primer pairs used 8 were useful for our purpose. the conservation of primer sequence point out the problem of neutrality of some microsatellite loci as this conservation c ...200314558449
implications of an individualistic lifestyle for species conservation: lessons from jealous beasts.polecat populations show a very low genetic diversity and a high inbreeding coefficient. furthermore, the estimate of effective population size is alarmingly low. polecats mustela putorius populations are structured into scattered breeding sub-units usually made up of one male and two females, according to a polygynous mating system. because a strict spatio-temporal segregation was observed between males and females, we propose to call individualistic such species. we suggest that the solitary h ...200314558446
[population aspects of sexual dimorphism in guild of the mustelidae: mustela lutreola, neovison vison, mustela putorius, martes martes as an example].size sexual dimorphism was investigated on 695 skulls of four mustelidae species. by extent of increasing of differences between sexes the species are placed in following order: european pine marten (martes martes), european mink (mustela lutreola), american mink (neovison vison), and european polecat (mustela putorius). extent of the dimorphism characterizes ecological plasticity of the species and is population characteristic. it is shown that m. martes takes specific and relatively narrow eco ...201623662464
phylogenetic relationships and divergence times among mustelids (mammalia: carnivora) based on nucleotide sequences of the nuclear interphotoreceptor retinoid binding protein and mitochondrial cytochrome b genes.phylogenetic relationships among 20 species-group taxa of mustelidae, representing mustelinae (mustela, martes, gulo), lutrinae (enhydra), and melinae (meles), were examined using nucleotide sequences of the nuclear interphotoreceptor retinoid binding protein (irbp) and mitochondrial cytochrome b genes. neighbor-joining and maximum-parsimony phylogenetic analyses on these genes separately and combined were conducted. while irbp performed better than cytochrome b in recovering more-inclusive clad ...200312655187
decline in endangered species as an indication of anthropic pressures: the case of european mink mustela lutreola western population.populations of threatened species, especially predators at the top of the food chain, may be affected by anthropic pressures. the endangered western population of european mink mustela lutreola has shown a large decline over 50% of its natural range. m. lutreola disappeared from northwestern france between 1984 and 1997, and the decline was associated with an increase in mustelid trapping, changes in watercourse quality, and habitat modifications due to agricultural practices. the pattern of dec ...200111915962
[chromosomal localization and evolutionary age of satellite dnas of mustelidae].dna reassociation kinetics were studied in the european mink (mustela lutreola), the american mink (m. vison), the marbled polecat (vormela peregusna). variation in dna quantity and heterochromatin amount occurs in connection with changes in the size of all kinetic fractions. moderately repetitive genome component is the most variable in these three species. cryptic cscl satellite of the stoat (m. erminea), ag+/cs2so4 satellites of the m. vison, v. peregusna were used for in situ homo- and heter ...19883250906
carnivora: the amino acid sequence of the adult european mink (mustela lutreola, mustelidae) hemoglobins.the complete amino acid sequences of the hemoglobins from the adult european mink (mustela lutreola) are presented. the erythrocytes contain two hemoglobin components and three globin chains. the isolation of globin chains achieved by ion-exchange chromatography on a column of cm-cellulose in 8 m urea buffer. the primary structure of globin chains and of the tryptic peptides determined in liquid- and gas-phase sequenators. the alignment of the alpha- and beta-chains with those of reported sequen ...20092363790
high trophic niche overlap between a native and invasive mink does not drive trophic displacement of the native mink during an invasion process.the pressure elicited by invasive species on native species significantly increases with the increase of the overlap of their ecological niches. still, the specific mechanisms of the trophic displacement of native species during the invasion process are unclear. the effects of the invasive american mink (neovison vison) on the critically endangered european mink (mustela lutreola) was assessed by analyses of diet and niche overlap during the invasion process. to do this, the isotopic composition ...202032785203
neoplasms and novel gammaherpesviruses in critically endangered captive european minks (mustela lutreola).the european mink (mustela lutreola) is a riparian mustelid, considered one of the most endangered carnivores in the world. alpha, beta and gammaherpesviruses described in mustelids have been occasionally associated with different pathological processes. however, there is no information about the herpesviruses species infecting european minks. in this study, 141 samples of swabs (oral, conjunctival, anal), faeces and tissues from 23 animals were analysed for herpesvirus (hv) using a pan-hv-pcr a ...202032619314
severe parasitism by versteria mustelae (gmelin, 1790) in the critically endangered european mink mustela lutreola (linnaeus, 1761) in spain.the riparian european mink (mustela lutreola), currently surviving in only three unconnected sites in europe, is now listed as a critically endangered species in the iucn red list of threatened species. habitat loss and degradation, anthropogenic mortality, interaction with the feral american mink (neovison vison), and infectious diseases are among the main causes of its decline. in the spanish foral community of navarra, where the highest density of m. lutreola in its western population has bee ...201830182257

conservation of the european mink (mustela lutreola): focus on reproduction and reproductive technologies.the european mink (mustela lutreola) is a small mammal, which belongs to the mustelidae family (carnivora). earlier, the range of distribution of this species encompassed much of the european continent. during the 20th century, the numbers of european mink declined and the range of its distribution became reduced to three fragmented populations; today this species faces extinction. the urgent necessity for effective conservation efforts to protect the european mink is accepted by the governmenta ...200818179633
embryo development and embryo transfer in the european mink (mustela lutreola), an endangered mustelid species.the european mink is an endangered mustelidae species and thus requires effective conservation measures, although little is known about reproduction in this species. in particular, preimplantation development has not been studied and, therefore, embryonic development and the growth of embryos was documented in the present study for european mink using light and fluorescent microscopy. embryos develop in the oviducts and then migrate into the uterus on day 6 post coitum (p.c.) at the morula stage ...200616737639
european mink-polecat hybridization events: hazards from natural process?determining the significance of hybridization events raises essential issues both in conservation and in evolutionary biology. here, we report a genetic investigation of sympatric polecat and endangered european mink populations. although the two species were morphologically very similar, the european mink and the polecat were easily discriminated from allozymes and microsatellites and showed a high level of private alleles (effective number of alleles: mink=1.45 and polecat=3.09). nevertheless, ...200615653561
transfer of european mink (mustela lutreola) embryos into hybrid recipients.the european mink is considered as a highly endangered mustelidae species. the objective of this study was to explore the intriguing possibility of embryo transfer from european mink to closely related mustelidae recipient females. to overcome interspecies pregnancy failure, embryos of european mink (mustela lutreola) were transferred into hybrid females obtained after mating of european polecat (mustela putorius) males and european mink (m. lutreola) females and vice versa. a total of 32 blasto ...200415226002
surgical recovery and successful surgical transfer of conventionally frozen-thawed embryos in the farmed european polecat (mustela putorius).surgical transfer of in vivo produced conventionally frozen-thawed embryos of farmed european polecat (mustela putorius) was investigated as a part of an ex-situ preservation program which has the long-term aim of developing a genome resource bank for the endangered european mink (mustela lutreola). eighteen oestrous yearling european polecat donors were mated once daily on two consecutive days using 13 fertile males. the donors were surgically flushed for embryos 8-9 days after the first mating ...200314519472
early embryonic development and in vitro culture of in vivo produced embryos in the farmed european polecat (mustela putorius).early embryonic development and in vitro culture of in vivo produced embryos in the farmed european polecat (mustela putorius) was investigated as a part of an ex situ conservation program of the endangered european mink (mustela lutreola), using the european polecat as a model species. the oestrus cycles of 34 yearling polecat females were monitored by visual examination of the vulval swelling and, to induce ovulation, the females were mated once daily on two consecutive days. sixteen yearling ...200312935873
amino acid sequences of mammalian kazal-type proteinase inhibitors from salivary glands.1. the amino acid sequences of bikazins (the double-headed kazal-type proteinase inhibitors from submandibular glands) isolated from the snow leopard (unica unica), the european mink (mustela lutreola), and the european pine marten (martes martes) were determined. 2. n-terminal domains of bikazins are characterized by a cysteine residue spacing that differs from that of c-terminal domains of bikazins and other kazal-type proteinase inhibitor domains. 3. n-terminal sequences of bikazins seem to b ...19938403842
reproduction in the european mink, mustela lutreola: oestrous cyclicity and early pregnancy.despite efforts undertaken to conserve the endangered european mink, its reproduction is still poorly studied. the aim was to study its reproductive cyclicity, faecal progesterone concentration and ovarian changes during early pregnancy, with the emphasis on the pre-implantation period and implantation. during the 2004 breeding season, oestrous cycle was monitored in 39 females as well as ovarian changes during early pregnancy in 22 females. during the 2007 breeding season, faecal progesterone c ...200918992118
viral metagenomic analysis of feces of wild small carnivores.recent studies have clearly demonstrated the enormous virus diversity that exists among wild animals. this exemplifies the required expansion of our knowledge of the virus diversity present in wildlife, as well as the potential transmission of these viruses to domestic animals or humans.201424886057
