| heterologous radioimmunoassay of fox lh: levels during the reproductive season and the anoestrus of the red fox (vulpes vulpes l.). | a heterologous radioimmunoassay using ovine lh as the labeled hormone, canine lh as the standard, and an antiovine lh rabbit serum was validated for the measurement of fox lh. physiological validation of the assay was evidenced by the high concentrations of lh at oestrus and following ovariectomy or the administration of lh-rh. throughout the year, plasma lh levels demonstrate important variations, being low during and after the luteal phase (1.4 +/- 0.3 ng/ml) (mean +/- se) and increasing durin ... | 1984 | 6378715 |
| experimental infections of sarcocystis cruzi, sarcocystis tenella, sarcocystis capracanis and toxoplasma gondii in red foxes (vulpes vulpes). | four littermate 6-wk-old red foxes (nos. 1-4) were fed toxoplasma gondii, sarcocystis cruzi, s. tenella and s. capracanis. one littermate fox (no. 5) served as the control. two foxes (nos. 1, 2) were fed tissue cysts of t. gondii and two foxes (nos. 3, 4) were fed oocysts of t. gondii. twenty-one to 42 days later, the same five foxes were used to test the infectivity of meat of goat, sheep, and ox experimentally inoculated with sarcocystis. fox 2 was fed goat meat and shed s. capracanis-like spo ... | 1983 | 6417347 |
| [excretion of the rabies virus in foxes after experimental infection]. | fourteen foxes (vulpes vulpes crucigera) were experimentally infected with rabies. the excretion of the virus in saliva was subjected to qualitative study. three different street strains isolated in the territory of the czech socialist republic were used for the intramuscular infection at the doses of 50 or 5000 micld50. the presence of the virus in saliva was demonstrated in 12 animals (86%). post-mortal examination revealed the virus in the salivary gland of 13 animals (93%). the virus started ... | 1984 | 6441330 |
| antibodies to berne virus in horses and other animals. | after inoculation into 2 foals, berne virus induced neutralizing antibody, but did not cause clinical symptoms. in a horizontal study of seropositive mares and their offspring, a decline of maternal antibodies and a sudden synchronous seroconversion in all foals were observed, again without clinical symptoms. the virus is widespread in the swiss horse population and has been so during the last decade; rises in antibody titers were noted in 9% of paired sera sampled at random. positive reactions ... | 1984 | 6506447 |

| experimental infection of red foxes (vulpes vulpes) with sarcoptes scabiei var. vulpes. | two of 3 red foxes became experimentally infected with sarcoptes scabiei v. vulpes isolated from a naturally infected wild fox. the first clinical sign was seen after 10 days. after 30 days hairless patches were observed on the back of one of the foxes while general hair loss continued slowly. on the other fox the only macroscopical changes was tangling of the hair. the foxes died after 67 and 94 days, respectively. both foxes were anaemic and in very poor condition. scratching was seen in only ... | 1984 | 6541832 |
| [inhibitory role of serotonin in manifestations of predatory aggression in the mink and silver fox]. | the predatory aggression of minks and silver-black foxes were estimated by their attacks on the rats placed in their cage. intraperitoneal injection of 5-hydroxytryptophan (serotonin precursor) in a dose of 100 mg/kg to foxes and 50 mg/kg to minks, caused a significant blocking of predatory aggression. estimation of serotonin level in the brain following administration of corresponding doses of 5-htp inhibiting the predatory aggression, revealed a considerable increase of serotonin content. it m ... | 1983 | 6607575 |
| infection of free-living carnivores with leptospires of the australis serogroup. | leptospires belonging to the australis serogroup were isolated from badgers (meles meles), mink (lutreola lutreola) and a fox (vulpes vulpes). most isolates were identified by cross-agglutination absorption as serovar muenchen but one isolate from a fox from surrey and one isolate from a badger from northern ireland were identified as serovar bratislava. maintenance of serovar muenchen by a wide range of free-living species is an ecological condition unique to great britain. | 1983 | 6636479 |

| helminth parasites of wild foxes (vulpes vulpes l.) in the netherlands. | to study the helminth fauna of wild foxes (vulpes vulpes) in the netherlands, material was collected from 139 foxes. the following parasites were found. cestodes: taenia spp. 53.3%, hymenolepis spp. 1.5%; trematodes: alaria alata 10.9%, cryptocotyle lingua 3.6%, euparyphium melis 1.5%, apophallus donicus 0.7%; nematodes: toxocara canis 73.7%, uncinaria stenocephala 59.9%, capillaria aerophila 46.8%, c. plica 23.5%, molineus patens 5.1%, crenosoma vulpis 4.5%, strongyloides spp. 0.7%. the tapewor ... | 1984 | 6741217 |
| bovine tuberculosis in domestic and wild mammals in an area of dorset. iii. the prevalence of tuberculosis in mammals other than badgers and cattle. | a large sample of the wild mammals found on a farm in south dorset were trapped and examined for the presence of mycobacterium bovis following the discovery of widespread infection in cattle and badgers. m. bovis was isolated from the lymph nodes of two out of 90 rats (rattus norvegicus) and one out of seven foxes (vulpes vulpes) but no lesions of tuberculosis were observed. it was concluded that the badger was the only species of wild mammal which was a reservoir of m. bovis in this area. | 1982 | 6752272 |
| sarcocystis of deer in south dakota. | the prevalence of sarcocystis in white-tailed deer (odocoileus virginianus) and mule deer (o. hemionus) in south dakota was determined through microscopic examination of tongue samples. the percentage of sarcocystis infection for both species of deer was determined for prairies east of the missouri river, west of the missouri river, and black hills of western south dakota. sixteen percent (n = 62) of the white-tailed deer tongues from east river, 69% (n = 42) from west river, and 74% (n = 23) fr ... | 1982 | 6808161 |
| prevalence and distribution of sarcocystis spp. among white-tailed deer of the southeastern united states. | sarcocysts were found by light microscopic examination of muscle in 199 (51%) of 390 white-tailed deer (odocoileus virginianus) from the southeastern united states. sarcocystis infections were detected more frequently in histologic sections of tongue (45%) than of heart (9%). sarcocysts were significantly more prevalent in adult deer (54%) than fawns (26%) (p less than .01). statistically significant differences in prevalence were not found in deer from different physiographic provinces or betwe ... | 1982 | 6808162 |
| sarcocystis and other coccidia in foxes and other wild carnivores from montana. | sarcocystis spp sporocysts were found in feces of 10.1% of 198 red foxes (vulpes vulpes), in 3.2% of 61 bobcats (lynx rufus), in 16.6% of 12 mountain lions (felis concolor), in 16.6% of 6 fisher (martes pennanti), and in none of 20 wolverines (gulo gulo), 4 mink (mustela vison), or 10 raccoons (procyon lotor). sarcocystis muris and toxoplasma gondii were not found in laboratory mice inoculated with feces of bobcats and mountain lions. | 1982 | 6816776 |
| karyotypic kinship between the blue fox (alopex lagopus linn.) and the silver fox (vulpes fulva desm.). | a karyotypic comparison between the blue fox and the silver fox revealed conservation of the chromosome arm as a unit, except for large heterochromatic blocks in 10 pairs of blue fox chromosomes and the complete absence of a common metacentric autosomal pair. this finding seems to indicate that their karyotypes evolved from a common ancestral karyotype, characterized by 70-76 acrocentric autosomes, mainly through a series of independent centric fusions. | 1983 | 6861523 |
| the susceptibility of the european red fox (vulpes vulpes) to infection with echinococcus granulosus of australian sheep origin. | a detailed comparative study was made of the development of echinococcus granulosus of australia sheep origin in european red foxes (vulpes vulpes) and dogs. no significant differences in growth, segmentation or maturation of the parasite between dogs or foxes was found, although worm burdens were slightly lower in foxes than in dogs. it is concluded that although the role of foxes in the epidemiology of hydatidosis in australia may not be significant, foxes should nevertheless be regarded as po ... | 1983 | 6882058 |

| [cellular immunity in the red fox vaccinated against rabies. studies with the lymphocyte transformation test]. | the best conditions for performing a lymphocyte transformation test have been studied in the red fox with three phytomitogens: phytohaemagglutinin, concanavalin a and pokeweed (phytolacca). these assays were carried out with varying different parameters of the reaction, among which concentration of mitogens, nature and duration of the lymphocyte cultures. isolation of fox lymphocytes gave lower yields than human lymphocytes, but were similar in number to those from other domestic animal species. ... | 1982 | 7128061 |
| fox society, contact rate and rabies epizootiology. | the social behaviour of red foxes vulpes vulpes is flexible and is adapted to their environment. consequently social organization varies from one habitat to another under the influence of factors such as the availability of food and the pattern of mortality. variations in social behaviour between fox populations are mirrored in different frequencies of encounters between individual foxes and hence in potentially different 'contact rates' for rabies. we present a computer model whose simulations ... | 1982 | 7128079 |
| the use of baits to estimate fox numbers. | within a research project on red fox ecology in different habitats around saarbrücken a new method to estimate fox numbers has been developed. baits are laid out on a 13 km2 large core area within each study area. in each km2 four times two chicken heads are deposited once a month, each time in a different site. the bait acceptance seems to reflect relative fox densities very well if compared with other estimates like the use of automatic cameras, tracking in snow or distribution of used fox den ... | 1982 | 7128083 |
