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 |
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 |
the intestinal helminths of the red fox and some other carnivores in southwest germany. | in south-west germany between 1975 and 1980, 3,573 red foxes (vulpes vulpes), 84 badgers (meles meles), 47 stone martens (martes foina), and 387 cats (felis catus) were examined for intestinal helminths. in foxes the extent of infections was: taenia crassiceps 24%, t. polyacantha 8%, t. taeniaeformis 0.6%, t. serialis 0.5%, mesocestoides leptothylacus 20%, mesocestoides sp. 0.2%, toxocara canis 32%, toxascaris leonina 3%, uncinaria stenocephala 26%. one to three foxes harboured t. hydatigena, t. ... | 1982 | 7072323 |
kala-azar in portugal. i. attempts to find a wild reservoir. | kala-azar is now increasing in portugal where it has been known since 1910. the natural region studied is made up of the western basins of the tejo and sado rivers with their important estuaries and the area south of lisbon. the climate and vegetation are mainly of the mediterranean type. kala-azar has always been endemic in the sub-region southwest of lisbon (45 cases from 1961 to 1978). in the setubal peninsula the disease has always had a low incidence (10 cases from 1961 to 1978). the alcáce ... | 1982 | 7097826 |

[enzymatic typing of 11 strains of leishmania isolated in mainland italy from the visceral murine, canine and vulpine forms. demonstration of an enzymatic variant in the fox (vulpes vulpes) and the dog]. | enzyme typing by starch gel electrophoretic techniques was carried out on 11 leishmania isolates from italy in laboratories in montpellier and london. the enzymes studied in the former were me, g-6-pd, 6-pgd, pgm, pgi, got (= asat), mdh and idh. in london slightly different procedures were used to examine me, 6-pgd, pgm, pgi and asat. in addition, sod, alat, nh, and mpi were studied. the combined data revealed that four rattus rattus and four dogs were infected with classical l. infantum (zymodè ... | 1982 | 7168524 |
immunization of foxes vulpes vulpes by the oral and intramuscular routes with inactivated rabies vaccines. | inactivated rabies vaccines prepared from common vaccine strains of virus were inoculated into foxes by the intramuscular and intestinal route. there were differences among the vaccines in the duration of antibody produced after intramuscular administration. inactivated vaccines deposited directly into the lumen of the duodenum by means of a fiberscope caused seroconversion in some foxes, especially following a booster dose, but the antibodies produced were for the most part of short duration. t ... | 1982 | 7172102 |
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 |
[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 |

response of mink, skunk, red fox and raccoon to inoculation with mink virus enteritis, feline panleukopenia and canine parvovirus and prevalence of antibody to parvovirus in wild carnivores in ontario. | mink virus enteritis, feline panleukopenia and canine parvovirus-2 were inoculated separately into groups of raccoon, mink, red fox and striped skunk. raccoons were highly susceptible to mink virus enteritis and feline panleukopenia, with animals developing clinical illness, and several dying within six to ten days of inoculation with lesions typical of parvovirus infection. both viruses were shed in high titre in the feces of infected raccoons, and high antibody titres were stimulated. raccoons ... | 1983 | 6309349 |
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 |
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 |

role of predation in short-term population fluctuations of some birds and mammals in fennoscandia. | we tested the hypothesis that synchronous fluctuations in small game species in boreal fennoscandia are caused by varying predation pressure. the main prey of predators are the cyclically superabundant voles. small game species (alternative prey) are rare compared to voles. the following 4 predictions were checked: (1) predators should shift their diet from main prey to alternative prey as main prey decline. - this was confirmed using data on red fox (vulpes vulpes l.) diet.; (2) the mortality r ... | 1984 | 28310714 |
seasonal reproductive endocrine profiles in two wild mammals: the red fox (vulpes vulpes l.) and the european badger (meles meles l.) considered as short-day mammals. | the annual cycle of the testicular function (testis and epididymis weights and plasma testosterone levels) were considered in relation to seasonal variations in plasma lh and prolactin concentrations in two wild european mammals: the badger and the fox. phase relationships were established between the annual prolactin cycles and daylight duration. the influence of castration on the seasonal variations in plasma lh levels was also studied. the resumption of activity in the testicular function occ ... | 1984 | 6695539 |
[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 |
