detection of space-time clusters and epidemiological examinations of scabies in chamois.in this paper some methodological approaches towards the detection of temporal, spatial and space-time clusters are presented and discussed in context with epidemiological factors of scabies in chamois. this presentation comprises in particular the use of the scan test (wallenstein, 1980) for the detection of temporal clusters and the tests developed by knox (1964) and mantel (1967) for the testing of spatiotemporal interactions. between 1952 and 1998 a total of 1689 cases of scabies in chamois ...200010936546
experimental infection of chamois (rupicapra pyrenaica parva) with sarcoptes scabiei derived from naturally infected goats.two chamois (rupicapra pyrenaica parva) out of a group of three were experimentally infected with sarcoptes scabiei derived from a naturally infected domestic goat. one of the chamois presented the first clinical manifestations (papules and desquamation) at 7 days post-infection, after 22 days crusts and alopecia appeared and after 41 days pruritus. the other chamois presented desquamation after 15 days and papules after 21 days and crusts and alopecia after 31 days. all these clinical manifesta ...200011244870
host specificity of abomasal nematodes in free ranging alpine ruminants.abomasums from 641 alpine wild ruminants representing five different species (cervus elaphus, capreolus capreolus, rupicapra rupicapra, capra ibex, ovis musimon) and from 19 domestic sheep (ovis aries) from alpine areas were examined in order to investigate the host-specificity of abomasal helminths. nine out of 20 helminth species were found in at least five different host species. a discriminant analysis was able to significantly discriminate the hosts on the basis of their helminth community ...200010842002
lung-tissue extract as an alternative to serum for surveillance for brucellosis in chamois.serological surveys are the most-used way to study diseases in free-ranging wild animals. however, the difficulty in obtaining a sufficient number of suitable serum samples is a major problem. to resolve this problem, we investigated the possibility of using lung-tissue extract in place of blood serum for searching for antibodies against brucella abortus. antibodies titres against b. abortus was tested from blood serum and lung-tissue extract from 112 chamois and 99 cattle. although in complemen ...200010673058
is the newly described vietnamese bovid pseudonovibos spiralis a chamois (genus rupicapra)?the "linh duong" (pseudonovibos spiralis), a newly described vietnamese bovid, has been shown to be related to the caprinae on the basis of the mitochondrial cytochrome b gene sequencing from horn fragments. to integrate the greatest available biodiversity we performed a new phylogenetic analysis including all genera of caprinae. unexpectedly, pseudonovibos is found to be robustly associated with rupicapra, and closer to the alpine than to the pyrenean chamois. several clues led us to interpret ...200010798196
gastro-intestinal nematode infections in four alpine chamois herds: influence of host density on helminth egg output.a three years survey on gastro-intestinal nematode egg output was carried out in four alpine chamois herds (rupicapra rupicapra rupicapra) from belluno province (italy). data were analysed in order to detect the influence of cattle presence and chamois density on egg output, and to evaluate the stability of host-parasite relationship. as expected, variations related to the season were present, with the major peak of egg output observed in the summer. results highlighted an unexpected inverse inf ...200111921539
mycoplasma conjunctivae infection is not maintained in alpine chamois in eastern switzerland.the occurrence of infectious keratoconjunctivitis (ikc) was assessed in alpine chamois (rupicapra rupicapra rupicapra) in grisons (switzerland) from 1950 to 1999. the first ikc outbreaks were reported in the 1950's. since then, the number of affected subpopulations constantly increased and, by 1999, ikc outbreaks were reported in 39 of 51 (77%) chamois sub-populations. from 1992-99, a total of 243 chamois which died of the consequences of ikc were recorded. the number of cases differed between y ...200212038129

phylogeography of chamois (rupicapra spp.) inferred from microsatellites.evolutionary relationships among populations of chamois (rupicapra spp.) across their current range from the caucasus to the cantabrian mountains were investigated. the allelic variation in 23 microsatellite loci was assessed in eight geographical populations, recognised as subspecies of the two closely related species r. pyrenaica and r. rupicapra. analysis of variance in allele frequencies (fst, statistics) and in repeat numbers (rst, statistics) showed these data to be highly structured. two ...200212450756
use of variograms to detect critical spatial distances for the knox's test.we aimed to find critical spatial distances (as an input quantity for the knox's test) using geostatistical methods. the spatiotemporal data set included all individual-chamois cases of scabies observed in styrian chamois populations in 137 of 2837 game preserves in styria (a province in the south of austria) over the time period between 1952 and 1998. theoretical variogram models were fitted to empirical variograms, which were calculated for cycles of 5 years. the unit of analysis was the mean ...200212062518
a review of mutual transmission of important infectious diseases between livestock and wildlife in europe.oral vaccination of red foxes against rabies has been practiced in europe since 1978 and has succeeded in greatly reducing the occurrence of this disease in foxes: this is an example of coordinated activity against a disease that affects both wild and domestic animals as well as humans. some examples of diseases that affect both domestic and wild animals in europe are: classical swine fever (hog cholera) in wild boars and domestic swine; myxomatosis and rabbit hemorrhagic disease in domestic and ...200212381556
infectious keratoconjunctivitis of ibex, chamois and other caprinae.infectious keratoconjunctivitis (ikc) caused by mycoplasma conjunctivae is a highly contagious ocular infection which is common in domestic sheep and goats. in the european alps, ikc is often observed in alpine chamois (rupicapra r. rupicapra) and in alpine ibex (capra i. ibex), but the disease has also been described in other wild caprinae in the pyrenees and in new zealand. the infection is characterised by inflammation of the conjunctiva and cornea, and in the most advanced stages, the cornea ...200211974619
dermatophilosis of alpine chamois (rupicapra rupicapra) in italy.a proliferative dermatitis similar to the condition generally referred to as strawberry footrot was observed in two alpine chamois (rupicapra rupicapra) from eastern alps, italy. branching septated filaments and packets of pas-positive coccoid organisms were observed in histological sections of the affected skin. the actinomycete, dermatophilus congolensis, was isolated from crusted lesions in one chamois. as wild ruminants are presumed to be a reservoir of infection in the alpine area, the auth ...200211980380
prevalence of antibodies to borrelia burgdorferi sensu lato in southern chamois (rupicapra pyrenaica) in spain.ungulates are involved in the epidemiology of borreliosis as maintenance hosts for vector tick species. we evaluated the prevalence of antibodies to borrelia burgdorferi sensu lato in two different populations of southern chamois in spain. forty-six sera (40.4%) were positive at titres >/=1 : 64 using an indirect immunofluorescence assay (ifat).200312864902
spatial patterns of mitochondrial and nuclear gene pools in chamois (rupicapra r. rupicapra) from the eastern alps.we have assessed the variability of maternally (mtdna) and biparentally (allozymes) inherited genes of 443 chamois (rupicapra r. rupicapra) from 19 regional samples in the eastern alps, to estimate the degree and patterns of spatial gene pool differentiation, and their possible causes. based on a total mtdna-rflp approach with 16 hexanucleotide-recognizing restriction endonucleases, we found marked substructuring of the maternal gene pool into four phylogeographic groups. a hierarchical amova re ...200312886279

molecular identification of a new pestivirus associated with increased mortality in the pyrenean chamois (rupicapra pyrenaica pyrenaica) in spain.pestivirus infection was identified in 16 of 17 chamois during an outbreak of a previously unreported disease in pyrenean chamois (rupicapra pyrenaica pyrenaica) in northeastern spain in 2001-02. by analysis of the 5' noncoding regions of the virus, we assigned it to the border disease virus cluster with pairwise similarity values ranging from 82.1% to 88.1%. it will be important to investigate the association of this pestivirus with disease in pyrenean chamois.200415650103
seroprevalence of pestivirus in four species of alpine wild ungulates in the high valley of susa, italy.wildlife, once infected, can serve as a reservoir of infectious diseases that form a constant threat to domestic livestock. to make control and eradication programs successful in the long-term, presence of pestivirus in wildlife populations should be monitored. the goal of this study was to investigate seroprevalence of pestivirus in four alpine wild ungulates in the high valley of susa, north-west italy. species studied were: red deer (cervus elaphus), roe deer (capreolus capreolus), wild boar ...200515922522
molecular dating of caprines using ancient dna sequences of myotragus balearicus, an extinct endemic balearic mammal.myotragus balearicus was an endemic bovid from the balearic islands (western mediterranean) that became extinct around 6,000-4,000 years ago. the myotragus evolutionary lineage became isolated in the islands most probably at the end of the messinian crisis, when the desiccation of the mediterranean ended, in a geological date established at 5.35 mya. thus, the sequences of myotragus could be very valuable for calibrating the mammalian mitochondrial dna clock and, in particular, the tree of the c ...200516332256
outbreaks of infectious keratoconjunctivitis in alpine chamois and ibex in switzerland between 2001 and 2003.five outbreaks of infectious keratoconjunctivitis (ikc) affecting alpine chamois and ibex in the western and central swiss alps were recorded in 2001 to 2003. mycoplasma conjunctivae was identified from conjunctival swabs by means of a nested pcr in 27 of the 28 chamois tested. the outbreaks occurred in an area covering 1590 km(2). deep valleys acted as a barrier to the spread of the disease. a total of 409 chamois and 33 ibex with clinical signs of ikc were reported. most of the chamois were sh ...200515995237
[mycobacterium avium subsp. paratuberculosis in wild animal species and cattle in styria/austria].infections with mycobacterium ovium ssp. paratuberculosis (m. paratuberculosis) are increasingly recognised worldwide. in addition to an increased prevalence of paratuberculosis in austrian cattle herds, recent years have also shown a rise in infections with m. paratuberculosis in wild red and roe deer, chamois and mouflon. during the period from june 2002 to september 2004, mesenteric lymph nodes were taken from a total of 483 wild animals hunted or found dead and from 338 deceased cattle. samp ...200516048043
cilia-associated respiratory (car) bacillus infection in adult red deer, chamois, and roe deer.cilia-associated respiratory (car) bacillus is an unclassified bacterium that colonizes the ciliated epithelium of airways in laboratory rats, laboratory mice, and laboratory and conventionally reared rabbits, cattle, goats, and pigs. data on the prevalence of car bacillus infection in wild animals are lacking. the present study demonstrated the occurrence of the organism in wild red deer (cervus elaphus hippelaphus), chamois (rupicapra rupicapra), and roe deer (capreolus capreolus) from the val ...200516107685

season effect on genitalia and epididymal sperm from iberian red deer, roe deer and cantabrian chamois.seasonality deeply affects the physiology and behavior of many species, and must be taken into account when biological resource banks (brbs) are established. we have studied the effect of seasonality on many reproductive parameters of free-ranging iberian red deer, roe deer and cantabrian chamois, living in spain. testicles from hunted animals were collected and sent to our laboratory at different times during the year. we recorded the weight and volume of testis, the weight of the epididymis an ...200515823344
astrocytoma in a chamois.astrocytomas represent the most common cerebral tumors in humans and in animals, and the fibrillary cytological subtype is the most frequently observed. in this report and for the first time, a thalamic astrocytoma is described in a chamois showing depressed mentation, pleurothotonus and circling to the right side.200516259411
recombination and the origin of sequence diversity in the drb mhc class ii locus in chamois (rupicapra spp.).we examined the evolutionary processes contributing to genetic diversity at the major histocompatibility complex (mhc) class ii drb locus in chamois (rupicapra spp., subfamily caprinae). we characterised the pattern of intragenic recombination (or homologous gene conversion) and quantified the amount of recombination in the genealogical history of the two chamois species, pyrenean chamois (rupicapra pyrenaica) and alpine chamois (rupicapra rupicapra). we found evidence for intragenic recombinati ...200515756546
steroid hormone related male biased parasitism in chamois, rupicapra rupicapra rupicapra.parasites are linked with their host in a trophic interaction with implications for both hosts and parasites. interaction stretches from the host's immune response to the structuring of communities and the evolution of biodiversity. as in many species sex determines life history strategy, response to parasites may be sex-specific. males of vertebrate species tend to exhibit higher rates of parasites than females. sex-associated hormones may influence immunocompetence and are hypothesised to lead ...200616497439
transport stress in southern chamois (rupicapra pyrenaica) and its modulation by acepromazine.chamois have been translocated for more than 100 years but their stress response to transport remains to be elucidated. in this study, 21 free-ranging southern chamois were captured, physically restrained and then transported. the animals were randomly injected intramuscularly with acepromazine (nine adult males, one adult female and one yearling male) or saline (five adult males, two adult females and three yearling males). heart rate and body temperature were monitored with telemetric devices, ...200616154370
[mesenchymal tumor in a female chamois. a case report].a free-living 15-year old female chamois was shot because of illness and emaciation. the examination of the internal organs revealed numerous firm whitish tumour nodules in liver,spleen, mesenterium and peritoneum. histologically the nature of tumour cells was identified as a metastasizing malignoma of mesenchymal origin. in addition to the blastoma, the parasite burden of the gastrointestinal tract and lungs did very likely contribute to the bad bodily condition of the chamois.200617009723
models of parasite biocoenosis dynamic: host density and gastrointestinal parasites in alpine chamois.host density is an important and widely accepted factor influencing microparasites epidemiology. in theory, host density would influence also macroparasite dynamic, although it would be achieved indirectly due to the presence of free-living infective stages of parasites. on this basis, it is expected that macroparasite abundance and prevalence would increase as host density increases, due to the higher probability for a new host to acquire infections from the environment. nevertheless, some surv ...200616881395
contact rates and exposure to inter-species disease transmission in mountain ungulates.the risk for a pathogen to cross the species barrier depends on the rate of efficient contacts between the species. however, contact rates between species have rarely been estimated from observations. here we estimate contact rates and exposure of chamois rupicapra rupicapra and alpine ibex capra ibex exposed to domestic pasteurellosis and brucellosis carried by sheep or cattle herds summering in mountain pastures. we use field observation data on animal positions treated in a geographic informa ...200616409647

real-time pcr for quantitative detection of chamois (rupicapra rupicapra) and pyrenean ibex (capra pyrenaica) in meat mixtures.a real-time quantitative polymerase chain reaction (pcr) technique was developed for the quantification of chamois and pyrenean ibex dnas in meat mixtures by using a sybr green detection platform. two species-specific systems and a eukaryotic endogenous system were combined in the real-time pcr approach to quantify the target species. in the specific systems, a 133 base pair (bp) fragment of the 12s rrna gene was amplified from chamois dna, and an 88 bp fragment from the d-loop region was amplif ...200818376592
epidemiological study of border disease virus infection in southern chamois (rupicapra pyrenaica) after an outbreak of disease in the pyrenees (ne spain).in 2001 and 2002, an outbreak of a previously unreported disease, associated with a border disease virus (bdv), caused high mortality in the southern chamois (rupicapra pyrenaica) population in the alt pallars-aran national hunting reserve in the catalan pyrenees (ne spain). between 2002 and 2006, sera and/or tissue samples taken from 116 healthy chamois shot during the hunting season, plus 42 from chamois affected by different diseases, were studied. a blocking enzyme-immunosorbent assay (elisa ...200817881162
diseases and reproductive success in a wild mammal: example in the alpine chamois.density-dependent and climatic factors affect reproduction and dynamics of wild ungulates. parasites can also decrease reproductive success through either a direct abortive effect or a negative impact on host growth and body condition. however, few studies have investigated the effect of parasitism on fecundity of ungulates in natural conditions. we studied three bacterial infections caused by salmonella enterica serovar abortusovis, chlamydophila abortus and coxiella burnetii. these bacteria ar ...200818189146
disentangling the effects of recombination, selection, and demography on the genetic variation at a major histocompatibility complex class ii gene in the alpine chamois.the major histocompatibility complex (mhc) harbours some of the most polymorphic loci in vertebrate genomes. mhc genes are thought to be subject to some form of balancing selection, most likely pathogen-mediated selection. hence, mhc genes are excellent candidates for exploring adaptive processes. in this study, we investigated the genetic variation at exon 2 of the drb class ii mhc locus in 191 alpine chamois (rupicapra rupicapra) from 10 populations in the eastern alps of italy. in particular, ...200819238706
babesia divergens-like organisms from free-ranging chamois (rupicapra r. rupicapra) and roe deer (capreolus c. capreolus) are distinct from b. divergens of cattle origin - an epidemiological and molecular genetic investigation.in 2005 and 2006, three adult female chamois (rupicapra r. rupicapra) were found dead with signs of acute babesial infection in the eastern swiss alps. pcr on dna extracted from blood or spleen of the carcasses revealed sequence identity of the amplified part of the 18s rrna gene with genbank entries attributed to babesia divergens of cattle origin or b. capreoli of wild ruminant origin which have never been described before in this region. examination of 424 blood samples from 314 head of cattl ...200818400402
sarcoptic mange in red deer from spain: improved surveillance or disease emergence?concern about emerging diseases has risen in recent years, and multihost situations have become increasingly relevant for wildlife management and conservation. we present data on asturias, northern spain, where 80 mangy red deer (cervus elaphus) have been found since the beginning of the epizootic in chamois (rupicapra pyrenaica parva) in 1993. we combine field and necropsy data with the results of a serosurvey using an in-house elisa test to evaluate if deer mange due to sarcoptes scabiei is an ...200818430519
babesia capreoli infections in alpine chamois (rupicapra r. rupicapra), roe deer (capreolus c. capreolus) and red deer (cervus elaphus) from switzerland.five cases of fatal babesiosis in free-ranging chamois (rupicapra r. rupicapra) attributed to infections with babesia capreoli were recently recorded in two regions of the swiss alps. to investigate the ecologic factors that possibly lead to those fatal b. capreoli infections in chamois, blood, ticks, and demographic data of 46 roe deer (capreolus c. capreolus), 48 chamois, and nine red deer (cervus elaphus) were collected in 2006 and 2007 in both affected regions. whereas no parasitic inclusion ...200919617485
detection of mycoplasma conjunctivae in the eyes of healthy, free-ranging alpine ibex: possible involvement of alpine ibex as carriers for the main causing agent of infectious keratoconjunctivitis in wild caprinae.mycoplasma conjunctivae is considered the major cause of infectious keratoconjunctivitis (ikc) in alpine ibex (capra i. ibex) and chamois (rupicapra r. rupicapra). while it is known that domestic sheep can act as healthy carriers for m. conjunctivae, this question has not been addressed in wild ungulates so far. in this study, bacteriological investigations and field observations were performed to assess whether free-ranging alpine ibex can be healthy carriers of m. conjunctivae. among 136 ibex ...200918834681
border disease virus among chamois, spain.approximately 3,000 pyrenean chamois (rupicapra pyrenaica pyrenaica) died in northeastern spain during 2005-2007. border disease virus infection was identified by reverse transcription-pcr and sequencing analysis. these results implicate this virus as the primary cause of death, similar to findings in the previous epizootic in 2001.200919239761
characterization of dictyocaulus species (nematoda: trichostrongyloidea) from three species of wild ruminants in northwestern spain.specimens of dictyocaulus spp. were extracted from the respiratory tracts of 3 ruminant hosts including roe deer (capreolus capreolus), red deer (cervus elaphus), and chamois (rupicapra rupicapra) from wild populations in the province of le6n, northwestern spain. the near-complete nuclear small-subunit ribosomal rna gene, and 2 regions of the large-subunit ribosomal rna gene, were amplified by pcr and sequenced. the ssu rdna gene sequences indicated a high level of similarity between the isolate ...200920050000
high prevalence of antibodies against chlamydiaceae and chlamydophila abortus in wild ungulates using two "in house" blocking-elisa tests.few data are available on the prevalence and relevance of chlamydiae in wild mammals, and even fewer studies have been conducted to determine the prevalence of chlamydophila abortus in wildlife hosts, most probably due to the absence of suitable species-specific serological assays for testing sera from wild animals. in light of this, we have developed two in-house blocking-elisa tests for detection of antibodies against chlamydiaceae and c. abortus in wild ungulates, and analyzed the relationshi ...200919010612
systemic toxoplasmosis and gram-negative sepsis in a southern chamois (rupicapra pyrenaica) from the pyrenees in northeast spain.a 6-year-old, male southern chamois (rupicapra pyrenaica) had an absence of flight response and was captured by hand in the catalan pyrenees in northeast spain. on clinical examination, the animal was in good body condition, and only atrophy of the right eye was observed. blood samples were collected and hematologic analysis performed, but no alterations were observed. the animal was sent to a wildlife rescue centre, where it developed chronic wasting and died after 32 days in captivity. at necr ...200919286506
analysing the isotopic life history of the alpine ungulates capra ibex and rupicapra rupicapra rupicapra through their horns.the horn of ungulate grazers offers a valuable isotopic record of their diet and environment. however, there have been no reports of the spatio-temporal variation of the isotopic composition of horns. we investigated patterns of carbon (delta(13)c) and nitrogen (delta(15)n) isotopic composition along and perpendicular to the horn axis in capra ibex and rupicapra rupicapra rupicapra to assess the effects of animal age, within-year (seasonal) and inter-annual variation, natural contamination and s ...200919575404
relationship between mtnr1a melatonin receptor gene polymorphism and seasonal reproduction in different goat breeds.the reproductive activity of goats bred in temperate latitude follows a seasonal pattern, influenced by annual variation in day length. daily variation in pineal melatonin secretion is the neuroendocrine signal recognized by animals through the link between this hormone and melatonin receptor 1a (mtnr1a). a total of 345 goats of different breeds (225 sarda, 30 saanen, 30 chamois coloured, 30 maltese and 30 nubian) with a kidding period in october-december or january-march were analysed to verify ...200918243602
nocardia otitidiscaviarum pneumonia in an alpine chamois (rupicapra rupicapra rupicapra).nocardia otitidiscaviarum was cultured from the lung of an alpine chamois (rupicapra rupicapra rupicapra) with suppurative bronchopneumonia. this is the first report of both nocardiosis and nocardia otitidiscaviarum in this wild ungulate species.200919361807
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 ...200919386479
investigation of the role of austrian ruminant wildlife in the epidemiology of malignant catarrhal fever viruses.malignant catarrhal fever (mcf) is an ubiquitous disease of cattle and other ruminants caused by ovine herpesvirus 2 (ovhv-2), which is endemic in sheep and transmitted from healthy carriers. further viruses of the mcf group are also able to induce mcf in ruminants. as alpine pasturing is very common in austria, possible contact with ruminant wildlife carrying and excreting mcf viruses might be suspected as an infection source. to investigate the epidemiologic role of austrian deer and chamois, ...200919395762
genetic variability of the prion protein gene (prnp) in wild ruminants from italy and scotland.the genetics of the prion protein gene (prnp) play a crucial role in determining the relative susceptibility to transmissible spongiform encephalopathies (tses) in several mammalian species. to determine the prnp gene variability in european red deer (cervus elaphus), roe deer (capreolus capreolus) and chamois (rupicapra rupicapra), the prnp open reading frame from 715 samples was analysed to reveal a total of ten single nucleotide polymorphisms (snps). in red deer, snps were found in codons 15, ...200919461206
the mycoplasma conjunctivae genome sequencing, annotation and analysis.the mollicute mycoplasma conjunctivae is the etiological agent leading to infectious keratoconjunctivitis (ikc) in domestic sheep and wild caprinae. although this pathogen is relatively benign for domestic animals treated by antibiotics, it can lead wild animals to blindness and death. this is a major cause of death in the protected species in the alps (e.g., capra ibex, rupicapra rupicapra).200919534756
serologic and virologic investigations into pestivirus infection in wild and domestic ruminants in the pyrenees (ne spain).an outbreak of disease associated to a border disease virus was described in the southern chamois (rupicapra pyrenaica) in spain in 2002. sera and/or spleen samples from 57 mouflon, 15 red deer, 21 roe deer, 3 fallow deer, 55 sheep, 32 cattle, and 68 goats sharing the chamois habitat were studied. an antibody elisa test yielded an inconclusive result in 2 mouflon and positive results in 5 goat sera. comparative virus neutralization tests were performed on the 2 inconclusive mouflons, 3 of the 5 ...200919084245
first report of mycoplasma conjunctivae from wild caprinae with infectious keratoconjunctivitis in the pyrenees (ne spain).frequent outbreaks of infectious keratoconjunctivitis have been reported in wild caprinae in europe. while etiologic studies in the alps indicate that the main etiologic agent is mycoplasma conjunctivae, there are few reports from other mountain areas, such as the pyrenees, where m. conjunctivae has never been reported. in 2006 and 2007, five adult pyrenean chamois (rupicapra pyrenaica; two males and three females) and one adult male european mouflon (ovis orientalis musimon) were studied; they ...200919204357
the genetic impact of translocations and habitat fragmentation in chamois (rupicapra) spp.the chamois is a useful species with which to investigate the combined genetic impact of habitat fragmentation, over hunting, and translocations. genetic variation within and between chamois (genus rupicapra) populations was analyzed in 259 individuals from 16 sampling sites located in italy, spain, slovakia, and the czech republic. two mitochondrial dna markers (control region and cytochrome b) and 11 nuclear microsatellites were typed. the principal results of this study can be summarized as f ...200919617524
an sei model for sarcoptic mange among chamois.we consider a simple model to study the dynamics of sarcoptic mange in a population of chamois. the epidemiological patterns observed during an epidemic in italy are reconstructed and key parameters of the model are estimated from field data. in particular, we calculate the basic reproductive ratio r (0), a threshold value for chamois density for the occurrence of an epidemic and the speed of propagation of the epidemic wave. the model is then used to obtain indications on the effect of culling ...201022876983
haloperidol and azaperone in drive-net captured southern chamois (rupicapra pyrenaica).we investigated the effect of haloperidol and azaperone in drive-net captured southern chamois (rupicapra pyrenaica). both tranquilizers have been successfully used in a wide range of wild species for reducing postcapture stress response. during 2005, 39 free-ranging chamois were captured, randomly injected intramuscularly with haloperidol (0.29 +/- 0.12 mg/kg; n=24), azaperone (1.1 +/- 0.82 mg/kg; n=6), or saline (0.5 ml; n=9), and restrained for 3 hr. heart rate was higher in the treated chamo ...201020688698
polycystic liver disease in senile chamois (rupicaprae rupicaprae).a polycystic disease of the liver was diagnosed in 12 adult, free-living chamois (rupicaprae rupicaprae) from alpine regions in the western part of austria. the animals (eight female, four male), all in advanced age (average 13 yr old), were killed by local hunters, most because of emaciation or abnormal behavior. the livers of the animals were enlarged and contained multiple, thin-walled cysts of various sizes filled with serous, amber fluid. no evidence for parasites was found in the cysts. th ...201020688671
some pathological features of lungs from domestic and wild ruminants with single and mixed protostrongylid infections.lungs of 40 ruminants from bulgaria with natural small lungworm (nematoda: protostrongylidae) infections were investigated, including 16 goats, 15 sheep, 7 mouflons, and 2 chamois. muellerius capillaris, m. tenuispiculatus, cystocaulus ocreatus, neostrongylus linearis, and protostrongylus brevispiculum infections were predominantly associated with nodular lesions, and protostrongylus rufescens, protostrongylus hobmaieri and protostrongylus rupicaprae were associated with extensive lesions locate ...201020445790
streptococcus rupicaprae sp. nov., isolated from a pyrenean chamois (rupricapra pyrenaica).biochemical and molecular genetic studies were performed on an unknown gram-positive catalase-negative coccus-shaped organism isolated from clinical samples of a pyrenean chamois. the microorganism was identified as a streptococcal species based on its cellular morphological and biochemical tests. 16s rrna gene sequence comparison studies confirmed its identification as a member of the genus streptococcus, but the organism did not correspond to any species of this genus. the nearest phylogenetic ...201020851916
retrospective study of pestivirus infection in pyrenean chamois (rupicapra pyrenaica) and other ungulates in the pyrenees (ne spain).in 2001 a new pestivirus (family flaviviridae) was associated with an outbreak of a previously unreported disease in pyrenean chamois (rupicapra pyrenaica) in the pyrenees (ne spain). molecular characterization assigned this virus to the border disease virus (bdv) cluster, bdv-4 genotype. a retrospective study was performed in archived sera and spleen of 74 pyrenean chamois and in archived sera of 28 mouflon (ovis ammon), 56 red deer (cervus elaphus), 43 roe deer (capreolus capreolus) and 29 fal ...201020961710
effects of early horn growth on reproduction and hunting mortality in female chamois.1. environmental conditions during early development can affect the growth patterns of vertebrates, influencing future survival and reproduction. in long-lived mammals, females that experience poor environmental conditions early in life may delay primiparity. in female bovids, annual horn growth increments may provide a record of age-specific reproduction and body growth. horn length, however, may also be a criterion used by hunters in selecting animals to harvest, possibly leading to artificial ...201021073455
