| comparison of the gonadal response of wild and laboratory field voles (microtus agrestis) to different photoperiods. | weanling male and female field voles from laboratory stock and from the f1 generation of wild-caught animals were placed in a long (16l:8d) or short (6l:18d) photoperiod for 28 or 56 days. both types of field vole showed the well-established effect of photoperiod upon sexual maturation, with animals in the long photoperiod having larger and more active gonads than animals in the short photoperiod. after 28 and 56 days laboratory stock females were more mature, sexually, and had a higher growth r ... | 1987 | 3546683 |
| serological studies of british leptospiral isolates of the sejroe serogroup. iii. the distribution of leptospires of the sejroe serogroup in the british isles. | some 94 strains of leptospires belonging to the sejroe serogroup isolated in the british isles were identified to the serovar level using specific factor sera. seventy strains were identified as leptospira interrogans serovar hardjo, 66 from cattle, 2 from pigs and 1 each from a sheep foetus and a human. twenty-four strains were identified as l. interrogans serovar saxkoebing, most strains were isolated from either wood mice, bank or field voles but strains were also isolated from badgers, a fox ... | 1987 | 3609169 |
| basic carriers of trichophyton mentagrophytes var. gypseum in the sverdlovsk region. | tests for myococarriers were made on 4.297 wild small mammals. clinical examinations only were carried out on 1,204 animals, both clinical and laboratory examinations on 3,093 animals. the suppurative form of trichophytosis was diagnosed in only one specimen of microtus oeconomus out of 1,204 animals examined. t. ectothrix microides was found in the hair taken from the focus. t. mentagrophytes var. gypseum was obtained by culture on nutrient media. no clinical signs of mycosis were found in 3,09 ... | 1987 | 3680938 |
| dnase i sensitivity in facultative and constitutive heterochromatin. | in situ nick translation allows the detection of dnase i sensitive and insensitive regions in fixed mammalian mitotic chromosomes. we have determined the difference in dnase i sensitivity between the active and inactive x chromosomes in microtus agrestis (rodent) cells, along both their euchromatic and constitutive heterochromatic regions. in addition, we analysed the dnase i sensitivity of the constitutive heterochromatic regions in mouse chromosomes. in microtus agrestis female cells the activ ... | 1985 | 3905296 |
| [the effect of methylnitronitrosoguanidine on dna synthesis in human and animal cells. inhibition of dna synthesis in asynchronous and synchronous cultured cells]. | methylnitronitrosoguanidine (mnng) is reported to inhibit dna synthesis in intact human cells, in the cells from patients with ataxia telangiectasia (at) or the cells from two rodent species. dna synthesis in different cell lines exhibits varying sensitivity to mnng inhibitory effect. 4-5-fold higher concentrations of mnng are required for 50% inhibition of dna synthesis in at cells or in field vole cells as compared with the concentration required for human cells or chinese hamster. the differe ... | 1985 | 3916233 |

| [demonstration of the virus of hemorrhagic fever with renal syndrome in the organs of rodents from natural foci of the infection in the ussr and the serodiagnosis of the diseases]. | an indirect fluorescent antibody test (ifat) and an enzyme-immunological test (elisa) were used for the detection of hfrs virus in organs of rodents from hfrs foci in the ussr. the virus was found in 115 out of 1120 bank voles, 9 out of 92 redbacked voles, and 2 field voles examined. spontaneous infection-rate of bank voles in population varied from 1.3 to 100% correlating with the epidemiological situation in foci. ifat and elisa were successfully used for serodiagnosis of hfrs. examinations of ... | 1981 | 6121425 |
| [transmission and course of parasitemia of babesia microti (hannover i strain) in the bank vole (clethrionomys glareolus) and field vole (microtus agrestis)]. | in germany only m. agrestis has been found to be naturally infected with b. microti while in other european countries several rodent species were found as mammalian hosts. in the laboratory c. glareolus got easily infected by german strains of b. microti, if parasitized blood was inoculated. but results of this method are not transferable to natural conditions. therefore this study was carried out. it was to prove whether c. glareolus is susceptible to b. microti transmitted by nymphs of i. rici ... | 1984 | 6150621 |
| association of pp60src and src protein kinase activity with the plasma membrane of nonpermissive and permissive avian sarcoma virus-infected cells. | the intracellular localization of pp60src and src protein kinase activity in avian sarcoma virus (asv)-infected chicken embryo fibroblasts and transformed and morphologically reverted field vole cells was examined by subcellular fractionation procedures. fractionation by differential centrifugation of dounce-homogenized cellular extracts prepared from vole cells showed that 83 to 91% of pp60src sedimented with particulate subcellular components from both transformed and revertant vole cells. a s ... | 1980 | 6257928 |
| loss of tumorigenicity correlates with a reduction in pp60src kinase activity in a revertant subclone of avian sarcoma virus-infected field vole cells. | we have recently isolated an interesting revertant subclone (revertant 866-4) of esv-infected field vole cells that is indistinguishable from uninfected vole cells with respect to its lack of transformed cell properties. these revertants are not only normal morphologically, but they do not grow in soft agar and are nontumorigenic in athymic nude mice. despite this lack of transformed cell properties, we have found that this cell line still contains pp60src at concentrations (0.30 microgram/mg ce ... | 1981 | 6261958 |
| karyotype analysis and quantitation of viral transforming genes in rous sarcoma virus transformed, revertant, and retransformed field vole cells. | comparative studies of the number of cellular chromosomes and viral genes, including the gene required for malignant transformation, were performed on several clones of rous sarcoma virus-transformed, revertant, and spontaneously retransformed field vole cells. the results of these studies indicate that no appreciable differences in either total viral gene equivalents or transforming gene sequences can be detected between transformed and revertant cell types, even though considerable differences ... | 1981 | 6262017 |
| increase in the phosphotransferase specific activity of purified rous sarcoma virus pp60v-src protein after incubation with atp plus mg2+. | pp60v-src, the product of the rous sarcoma virus src gene, was partially purified by immunoaffinity chromatography from extracts of rous sarcoma virus-transformed field vole cells. incubation of this preparation with atp plus mg2+ and subsequent repurification by chromatography on hexylamine-agarose resulted in a net increase in the specific activity of the src protein kinase. this increase in phosphotransferase activity was detected by using a variety of substrates including casein, tubulin, an ... | 1983 | 6314123 |

| identification of a reservoir of leptospira interrogans serovar muenchen in voles (microtus agrestis and clethrionomys glareolus) in england. | infection with leptospires of the australis serogroup is widespread in voles in southern england and the serovar identification of five randomly-selected isolates was determined by cross agglutination absorption. two isolates from short-tailed voles (microtus agrestis) and three isolates from bank voles (clethrionomys glareolus) were all identified as serovar muenchen. the only previous isolation of this serovar is that from a human in germany. | 1983 | 6372316 |
| observations on uterine mast cells during early pregnancy in the vole, microtus agrestis. | the vole, microtus agrestis, was chosen for this study of mast cells during early pregnancy because this species does not show spontaneous estrous cycles. mast cell numbers in the uterus are known to vary during the estrous cycle in some species (rat, cow, syrian hamster). mast cell changes during early pregnancy in the vole could not reflect hormonal changes which had occurred during a preceding estrous cycle. mast cells in the uterus (myometrium, endometrium, and mesometrial triangle) and ear ... | 1984 | 6375459 |
| microtus species as new herbivorous laboratory animals: reproduction; bacterial flora and fermentation in the digestive tracts; and nutritional physiology. | in a study of the possible introduction of japanese field vole (microtus montebelli ) and hungarian voles (m. arvalis) as herbivorous experimental animals, the following biological characteristics were investigated: breeding and reproductive performance; bacterial flora and fermentation in the digestive tracts; and nutritional physiology. the animals are polyestrus , show postpartum estrus on the day of parturition, and there is little or no delay in implantation due to lactation, especially in ... | 1984 | 6377675 |
| effect of mating on the metabolic activity of the brain and pituitary gland assessed by [14c]2-deoxyglucose in a reflex ovulator, the vole (microtus agrestis). | the neural pathways involved in reflex ovulation in the vole (microtus agrestis) have been investigated with the [14c]2-deoxyglucose (2-dg) method. female voles were injected i.p. with 2-dg and either not mated, sham-mated (mounted by males by vagina was taped) or mated for a period of 45 min after the injection, after which the animals were decapitated. the brain was processed for autoradiography and the relative metabolic activities (rma) of selected areas of the brain and pituitary gland were ... | 1984 | 6388729 |
| [breeding and rearing of japanese field voles (microtus montebelli milne-edwards) and hungarian voles (microtus arvalis pallas) as new herbivorous laboratory animal species]. | microtus species are very useful as experimental small animals with herbivorous characteristics. in this report, to approach establishment of the use of japanese field voles (m. montebelli) and hungarian voles (m. arvalis) as experimental animals, the biological characteristics, breeding methods and reproductive performance of these animal species were comparatively investigated. the number of chromosomes of m. arvalis is 12n = 46, differing from those of m. montebelli, 2n = 30. the breeding and ... | 1982 | 6754391 |
| cell cycle-dependent regulation of excision repair of uv damage. | the incision step of excision repair of uv-damaged dna, represented by the accumulation of dna strand breaks in the presence of hydroxyurea and 1-beta-d-arabinofuranosylcytosine, was measured in cultured cells of microtus agrestis during quiescence and at different times after release from quiescence. the uv dose-dependent kinetics of enzymic incision change rapidly through the first cell cycle after release, with a maximum potential for enzymic incision and a minimum affinity of the incision sy ... | 1982 | 6754399 |
| feulgen-dna changes in the germ cells of the male vole (microtus agrestis) during their development. | consistent with changes in ploidy during germ cell maturation, the quantity of feulgen dna in round spermatids of voles is approximately a quarter of that in primary spermatocytes. the amount increases slightly in elongated spermatids, and then declines in spermatozoa from the testis, epididymis and vas deferens, below the level of round spermatids. simultaneously nuclear area decreases so that in spermatozoa it is about one tenth that of primary spermatocytes. the rise in feulgen dna in elongat ... | 1980 | 6760273 |
| [occurrence of white japanese field vole (microtus montebelli) in the laboratory]. | some field voles with a white coat color were found in the breeding process in the laboratory, originated from a wild population captured in the riverside of the arakawa in okegawa, saitama prefecture in japan. they had been raised in a room and fed with pelleted feed for herbivore. an attempt was made to analyze their breeding records and mode of inheritance for the white coat color. as a result, the average litter size was 3.80 +/- 1.52, and the age of the first birth was 121 +/- 46.8 in days. ... | 1982 | 6762967 |
| [the life-history of sarcocystis singaporensis zaman and colley, 1976 in the definitive and intermediate host (author's transl)]. | sporulated oocysts and sporocysts (9.3 x 7.3 micrometer) of sarcocystis singaporensis - isolated from freshly imported snakes (python reticulatus) - were fed to various animals to test their function as suitable intermediate hosts (nmri-mice, albino rats, meriones unguiculatus, golden hamsters, guinea pigs, mastomys natalensis, field-voles [microtus arvalis], pigeons, and chickens). only in rats were muscle-cysts formed. the optimal dose was 150 sporocysts per rat. two generations of merogony co ... | 1980 | 6771934 |
| gonadotrophin levels in male voles (microtus agrestis) reared in long and short photoperiods. | male voles were reared from birth to the age of 56 days in photoperiods of 16l:8d or 6l:18d. in 16l:8d testes increased 10-fold in size between the age of 14 and 56 days, and there were concomitant increases in diameter of seminiferous tubules and seminal vesicle weight. spermatozoa were present in tubules by 35 days. in 6l:18d no significant changes with age occurred in testis size, diameter of seminiferous tubules or seminal vesicle weight. lh secretion increased with age in 16l:8d, but not in ... | 1982 | 6816930 |
| prevalence of pneumocystis carinii delanoë & delanoë, 1912 in rodents in denmark. | pneumocystis carinii has been found in 17 of 90 (19%) wild living trapped brown rats (rattus norvegicus). the positive brown rats originated from about 25% of the trapping localities examined. among brown rats of two breeding stocks, h and s, pneumocysts were found in 43.5% of the h rats, but in none of the s rats. by keeping brown h rats on a low protein diet for 8 weeks, it was possible to augment the prevalence to 53.8%. pneumocystis carinii has furthermore been found in one of eight (12.5%) ... | 1980 | 6965782 |
| effect of bromocriptine treatment on the ovulatory response to oestradiol benzoate in the reflex ovulator, microtus agrestis. | in some animals which ovulate spontaneously, oestrogen may stimulate prolactin secretion and high levels of prolactin may inhibit steroid-induced surges of lh. the possibility was investigated that such conditions were operating in the reflex ovulator microtus agrestis to prevent spontaneous ovulation. however, bromocriptine treatment to suppress prolactin secretion did not enhance the poor ovulatory response to administration of oestradiol benzoate. | 1980 | 6988538 |
