| karyotype of canine soft tissue sarcomas: a multi-colour, multi-species approach to canine chromosome painting. | many canine tumour types represent useful models for tumours also found in humans. studies of chromosomal abnormalities in canine tumours have been impeded by the complexity of the canine karyotype (2n = 78), which has made accurate identification of rearranged chromosomes difficult and laborious. to overcome this difficulty we have developed a seven-colour paint system for canine chromosomes, with six sets of chromosome paints covering all chromosomes except y. several pairs of canine autosomes ... | 2004 | 15702421 |
| detecting danger--or just another odorant? olfactory sensitivity for the fox odor component 2,4,5-trimethylthiazoline in four species of mammals. | 2,4,5-trimethylthiazoline (tmt) is a volatile component of the anal gland secretion of the red fox and elicits behavioral and physiological fear responses in the rat. using instrumental conditioning paradigms, we determined olfactory detection thresholds for tmt in three rats, a natural prey species of the red fox, and compared their performance to that of three squirrel monkeys, three spider monkeys and four pigtail macaques, all non-prey species of the red fox. we found that the rats were able ... | 2004 | 15708773 |
| field evaluation of an intravital diagnostic test of echinococcus multilocularis infection in red foxes. | echinococcus multilocularis parasitizes the small intestine of red foxes (vulpes vulpes) and other carnivores, and has a wide distribution throughout the northern hemisphere. this cestode is the causative agent of human alveolar echinococcosis, a life-threatening helminth zoonosis. in 2000-2002, 2130 red foxes were examined for its presence in slovakia, with a total prevalence of 30.7%. the data on occurrence were obtained by the combination of necropsy of small intestines from red foxes and cop ... | 2004 | 15725534 |
| first record of trichinella pseudospiralis in the slovak republic found in domestic focus. | infection of trichinella spp. is widespread among wildlife in slovakia and the red fox (vulpes vulpes) is the main reservoir of trichinella britovi. trichinella spiralis has been rarely documented in sylvatic and domestic animals of this country. during routine examination of domestic pigs at the slaughter, trichinella larvae were detected by artificial digestion in a domestic pig of a large-scale breeding farm in eastern slovakia. the parasite has been identified by molecular (pcr) and biochemi ... | 2004 | 15725537 |
| oral vaccination of wildlife against rabies: opportunities and challenges in prevention and control. | rabies is an acute, progressive, fatal encephalitis caused by viruses in the family rhabdoviridae, genus lyssavirus. rabies virus is the representative member of the group. warm-blooded vertebrates are susceptible to experimental infection, but major primary hosts for disease perpetuation encompass bats and mammalian carnivores. the dog is the global reservoir, and important wild carnivores include foxes, raccoons, skunks, and mongoose, among others. traditionally, reliance upon long-term, wides ... | 2004 | 15742629 |
| elimination of terrestrial rabies in western european countries. | since the late 1930s, the red fox (vulpes vulpes) has been the main vector of rabies in europe. practically, decimation of fox population did not prevent the spread of the disease. the only efficient method to control wildlife rabies consisted in using oral vaccination by depositing vaccine baits containing a capsule or a plastic sachet filled with an attenuated anti-rabies liquid vaccine throughout fox habitats. several live virus vaccines have been and are currently being used: the sad b19 and ... | 2004 | 15747421 |
| rabies in red foxes (vulpes vulpes) experimentally infected with european bat lyssavirus type 1. | the susceptibility of red foxes (vulpes vulpes) to european bat lyssavirus type 1 (eblv-1) infection was examined. eight foxes were inoculated intramuscularly (i.m.) with 10(4.9) foci-forming units (ffu) (n = 4) and 10(5.1) ffu (n = 4) and observed for up to 90 days. all foxes showed manifestations of a neurologic disorder (e.g. seizures, myoclonus, agitation), starting as early as 5 days post-infection (p.i.). subsequently, all animals showed improvement followed by one or more relapses. one fo ... | 2004 | 15525359 |
| arctic rabies--a review. | rabies seems to persist throughout most arctic regions, and the northern parts of norway, sweden and finland, is the only part of the arctic where rabies has not been diagnosed in recent time. the arctic fox is the main host, and the same arctic virus variant seems to infect the arctic fox throughout the range of this species. the epidemiology of rabies seems to have certain common characteristics in arctic regions, but main questions such as the maintenance and spread of the disease remains lar ... | 2004 | 15535081 |
| biotin-avidin amplified elisa for detection of antibodies to sarcoptes scabiei in chamois (rupicapra spp.). | scabies is a major threat to the well being of mountain-dwelling bovid hosts, rupicapra rupicapra and rupicapra pyrenaica. severe outbreaks are in progress over a significant part of their distribution area and resource managers demand improved methods to monitor, analyse and possibly forecast the spread and effects of scabies at the population level. an amplified capture enzyme-linked immunosorbent assay was developed to detect antibodies to sarcoptes scabiei in chamois (rupicapra spp.) serum. ... | 2004 | 15535959 |
| circulation of toxocara spp. in suburban and rural ecosystems in the slovak republic. | toxocara spp., the common roundworms of domestic and wild animals, are the causative agents of larval toxocarosis in humans. the migration of toxocara larvae in men causes clinical syndrome, called larva migrans visceralis or larva migrans ocularis. the objective of the present work was to investigate the prevalence of toxocarosis in dogs, red foxes (vulpes vulpes), and small mammals in the slovak republic. t. canis infection was diagnosed in 16.6% out of 145 dogs examined. young animals showed ... | 2004 | 15567594 |
| rabies encephalitis following fox bite--histological and immunohistochemical evaluation of lesions caused by virus. | rabies caused by fox bite is uncommon, most cases being caused by bite of rabid dogs (95%). we report a 45-year-old lady with rabies encephalomyelitis caused by bite of a rabid wild fox (vulpes vulpes), a species prevalent in the deccan plateaus of central india. though foxes are known to be susceptible to rabies, literature on the pathological changes caused by fox bite rabies in humans is scarce. unlike the mild histological alterations described in canine rabies, a florid encephalitic process ... | 2004 | 15584211 |
| processes leading to a spatial aggregation of echinococcus multilocularis in its natural intermediate host microtus arvalis. | the small fox tapeworm (echinococcus multilocularis) shows a heterogeneous spatial distribution in the intermediate host (microtus arvalis). to identify the ecological processes responsible for this heterogeneity, we developed a spatially explicit simulation model. the model combines individual-based (foxes, vulpes vulpes) and grid-based (voles) techniques to simulate the infections in both intermediate and definite host. if host populations are homogeneously mixed, the model reproduces field da ... | 2004 | 14711588 |
| study on the ecological distribution of alveolar echinococcus in hulunbeier pasture of inner mongolia, china. | a study on the ecological distribution of alveolar echinococcus was carried out in the hulunbeier pasture of inner mongolia, china during 1998 and 1999. animals examined included wolves (canis lupus), red foxes (vulpes vulpes), sand foxes (vulpes corsac), domestic dogs (canis familiaris), microtus brandti, meriones unguiculatus, citellus dauricus, allactaga sibirica, phodopus sungorus and ochotona daurica. three wolves were found to be infected with e. granulosus. two sand foxes were infected wi ... | 2004 | 15030006 |
| a serosurvey of hepatozoon canis and ehrlichia canis antibodies in wild red foxes (vulpes vulpes) from israel. | a seroepidemiological survey was conducted to investigate the prevalence of antibodies reactive with ehrlichia canis and hepatozoon canis antigens in free-ranging red foxes (vulpes vulpes) in israel. of 84 fox sera assayed, 36% were seropositive for e. canis by the indirect fluorescent antibody (ifa) test and 24% were positive for h. canis using an enzyme-linked immunosrbent assay (elisa). canine ehrlichiosis and hepatozoonosis appear to be endemic in the wild red fox populations in israel, and ... | 2004 | 15036573 |
| molecular and biologic characteristics of toxoplasma gondii isolates from wildlife in the united states. | toxoplasma gondii isolates can be grouped into 3 genetic lineages. type i isolates are considered more virulent in outbred mice and have been isolated predominantly from clinical cases of human toxoplasmosis, whereas types ii and iii isolates are considered less virulent for mice and are found in humans and food animals. little is known of genotypes of t. gondii isolates from wild animals. in the present report, genotypes of isolates of t. gondii from wildlife in the united states are described. ... | 2004 | 15040668 |
| assessing anti-rabies baiting--what happens on the ground? | rabies is one of the most hazardous zoonoses in the world. oral mass vaccination has developed into the most effective management method to control fox rabies. the future need to control the disease in large countries (i.e. eastern europe and the americas) forces cost-benefit discussions. the 'increase bait density' option refers to the usual management assumption that more baits per km2 could compensate for high fox abundance and override the imperfect supply of bait pieces to the individual fo ... | 2004 | 15113448 |
| the dog genome map and its use in mammalian comparative genomics. | the dog genome organization was extensively studied in the last ten years. the most important achievements are the well-developed marker genome maps, including over 3200 marker loci, and a survey of the dna genome sequence. this knowledge, along with the most advanced map of the human genome, turned out to be very useful in comparative genomic studies. on the one hand, it has promoted the development of marker genome maps of other species of the family canidae (red fox, arctic fox, chinese racco ... | 2004 | 15131351 |
| a marker set for construction of a genetic map of the silver fox (vulpes vulpes). | the silver fox, a variant of the red fox (vulpes vulpes), is a close relative of the dog (canis familiaris). cytogenetic differences and similarities between these species are well understood, but their genomic organizations have not been compared at higher resolution. differences in their behavior also remain unexplained. two silver fox strains demonstrating markedly different behavior have been generated at the institute of cytology and genetics of the russian academy of sciences. foxes select ... | 2004 | 15220384 |
| anaplasma phagocytophilum: an emerging tick-borne pathogen in hungary and central eastern europe. | anaplasma phagocytophilum (formerly ehrlichia phagocytophila, ehrlichia equi and anaplasma phagocytophila) is the causative agent of granulocytic ehrlichiosis (anaplasmosis) in humans, horses, sheep, cattle, dogs and cats. in the present study, 452 european sheep ticks (ixodes ricinus) collected from 100 red foxes (vulpes vulpes) in hungary were tested for the pathogen, as 112 pools each containing five or fewer ticks from one fox. six of the pools, representing ticks from six different foxes, w ... | 2004 | 15228721 |
| effect of selection for behavior on pituitary-adrenal axis and proopiomelanocortin gene expression in silver foxes (vulpes vulpes). | silver foxes from a commercial population (farm bred or unselected for behavior control) and from populations selected for tame behavior and enhanced aggressiveness towards man have been investigated. plasma cortisol and adrenocorticotropic hormone (acth) levels, pituitary acth levels, pomc gene expression in the anterior pituitary, and corticotropin-releasing factor (crf) gene expression in the hypothalamus were assessed. the results indicate that the males from the tame-behavior group have low ... | 2004 | 15276817 |
| cloning and characterization of the bovine testicular ph-20 hyaluronidase core domain. | the core nucleotide sequence of bovine (bos taurus) testicular ph-20 hyaluronidase was cloned using one step rt-pcr. the 5' and 3' regions were cloned separately and a sequence overlap of 124 bp facilitated the fusion of these two fragments by overlapping pcr, resulting in a concatenated sequence of 1422 bp. this nucleotide sequence and its deduced amino acid sequence were compared to homologous sequences from eight other mammal species. the bovine sequences were most similar to those of the pig ... | 2004 | 15289682 |
| testing the biomechanical optimality of the wall thickness of limb bones in the red fox (vulpes vulpes). | the optimum for the ratio k of the internal to external diameter of a marrow-filled tubular bone with minimum mass designed to withstand a given type of strength (yield/fatigue, stiffness, fracture or impact) depends on q = rhom/rhob only, where rhom and rhob are the densities of marrow and bone. with computer-assisted evaluation of radiographs of 62 femurs in the red fox (vulpes vulpes) we measured the values of k. the mean and standard deviation of k are 0.68 and 0.036, and k changes in the ra ... | 2004 | 15336931 |
| corticosteroid treatment does not reactivate canine herpesvirus in red foxes. | to study canine herpesvirus (chv) reactivation from red foxes (vulpes vulpes), 29 foxes with varying chv antibody and chv carrier status were treated with methylprednisolone acetate, a glucocorticosteroid drug with prolonged immunosuppressive effect in dogs. in the first experiment, 17 foxes with unknown chv carrier status were treated once with methylprednisolone: in the second experiment, five foxes were treated twice, 4 mo after being intravenously chv infected; and in the third experiment, s ... | 2004 | 15362823 |
| oral vaccination of captive arctic foxes with lyophilized sag2 rabies vaccine. | arctic foxes (alopex lagopus) were immunized with lyophilized sag2 oral rabies vaccine. the effectiveness of this vaccine was determined by serologic response and survival to challenge by rabies virus isolated from a red fox from alaska (usa). no vaccine virus was found in saliva 1-72 hr after ingestion. at 2 wk after vaccination, all foxes had seroconverted, with rabies virus neutralizing antibody levels of 0.2-3.1 iu ml(-1). all vaccinated foxes survived to week 17 after challenge, and hippoca ... | 2004 | 15362836 |
| characterization and mapping of canine microsatellites isolated from bac clones harbouring dna sequences homologous to seven human genes. | human primers specific for the genes lep, hbb, pax3, esr2, tph1, abca4 and atp2a2 were used to identify clones in a canine bac library. subcloning of the positive bacs in plasmids, screening with microsatellite motifs and subsequent sequencing allowed for the identification of eight novel microsatellites. the presence of the gene of interest was confirmed by sequencing the polymerase chain reaction (pcr) products amplified in the positive bacs. fluorescent in situ hybridization (fish) using the ... | 2004 | 15373746 |
| occurrence of helicobacter infection in the gastric mucosa of free-living red foxes (vulpes vulpes). | we studied gastric helicobacter spp. in five red foxes (vulpes vulpes). samples of stomach from the cardia, corpus, pyloric antrum, and duodenum were subjected to histopathologic, immunohistochemical, and transmission electron microscopy (tem) examination for the presence of helicobacter and gastritis. all foxes had gastric helicobacter-like organisms (ghlos) on examination by light microscopy and tem. gastric helicobacter-like organisms were present in all areas of the stomachs. chronic mild or ... | 2004 | 15465724 |
| epidemiology of alveolar echinococcosis in southern cantal, auvergne region, france. | alveolar echinococcosis (ae) is a helminth zoonosis which is encountered only in the northern hemisphere. in central france, the auvergne region represents the most western and southern extension of this helminthiasis. in 1999, a human case of ae was diagnosed in the southern part of the cantal department, where ae was supposed absent, and an epidemiological survey was subsequently carried out. the transmission of the zoonosis in the sylvatic and peridomestic definitive hosts was studied, as wel ... | 2004 | 15469627 |
| immunological tools for the assessment of both humoral and cellular immune responses in foxes (vulpes vulpes) using ovalbumin and cholera toxin b as an antigenic model. | the immune response in the fox (vulpes vulpes), despite the success of the oral rabies vaccine is not well characterized, and specific immunological tools are needed. to investigate both the humoral and cellular immune response, we used ovalbumin (ova) and cholera toxin b (ctb) as an antigenic model to set-up elisa and elispot antibodies secreting cells (asc) assays in the fox model. identification of antibodies that cross-react with fox immunoglobulin was performed by western blot, and their us ... | 2004 | 15474706 |
| trichinella pseudospiralis foci in sweden. | in sweden, the prevalence of trichinella infection in domestic pigs has greatly decreased since the 1970s, with no reports in the past 4 years. however, infected wild animals continue to be found. the objective of the present study was to identify the species of trichinella present in animals of sweden, so as to contribute to the knowledge on the distribution area and hosts useful for the prevention and control of this zoonosis. in the period 1985-2003, trichinella larvae were detected in the mu ... | 2004 | 15482889 |
| predation risk and longevity influence variation in fitness of female roe deer (capreolus capreolus l.). | we studied the effects of population density, red fox predation risk, individual body mass and longevity on female fitness in a free-ranging roe deer population. during the study, population density varied from 9.3 to 36.1 deer km(-2), and red fox abundance varied strongly over years owing to a sarcoptic mange outbreak. in support of our predictions, long-lived females had higher fitness than short-lived ones. further, fortunate female roe deer that gave birth in years of low red fox abundance a ... | 2004 | 15504011 |
| salmonella isolates from wild birds and mammals in the basque country (spain). | the authors investigated the prevalence of salmonella spp. in 205 wild birds and mammals belonging to 45 species during the years 2001 and 2002 in the basque country (spain). salmonella was isolated from 16 (7.8%) animals. the prevalence was 8.5% (7/82) in birds, and 7.2% (9/123) in mammals. nine serotypes, all of them belonging to the species salmonella enterica, were identified: two isolates of typhimurium (from 1/3 griffon vultures [gyps fulvus], and 1/5 sparrowhawks [accipiter nisus]); one o ... | 2004 | 15861885 |
