| small wild rodents rabies in czechoslovakia. | during a period of 1969-1979 a total of 3174 small wild rodents of the genus muridae and microtinae (predominantly microtus arvalis) were examined. the animals were trapped in five localities differing both in type of ecological conditions and epizootologic situation. fox-rabies occurred here either enzootically, or epizootologically, or had been completely absent for many years in one of the localities investigated. of the 71 isolated strains of rv 18 strains were isolated from brain, 25 from b ... | 1982 | 6749977 |
| [experimental latent tularemia in common voles]. | common voles (microtus subarvalis) were infected with tularemia by feeding them with the corpses of the animals which had been infected with francisella tularensis strain having somewhat decreased virulence. this resulted in nonlethal infection in 14 out of 433 voles used in the experiment. a considerable part of the animals having had the infection developed bacterial carriership (11 out of 13 animals) with bacteriuria (8 out of 11 animals) lasting up to 2 months. the persistence of francisella ... | 1982 | 7043979 |
| small terrestrial mammals as reservoirs of leptospires in the sava valley (croatia). | small mammals trapped in seven sites along the river sava in croatia were examined for leptospiral infection by renoculture and serological methods. of the 1749 animals caught 702 were examined by renoculture method and 626 were tested by microagglutination-lysis. the dominant animals species caught were microtus arvalis (672 animals) and apodemus agrarius (552 animals). of the 115 strains of leptospires isolated the dominant serotypes were l. grippotyphosa (40) and l. pomona (35). five strains ... | 1982 | 7049871 |
| [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 |
| variability of hematocrit value, blood serum beta- and gamma-globulin level and body weight in different transferrin genotypes of common vole (microtus arvalis, pallas 1779) from natural population. | 1. heterozygotes tff/tfe of voles did not differ in body weight, they had higher hematocrit value (males and females), higher beta-globulin fraction (males) or higher gamma-globulin fraction (females). 2. a smaller variability of parameters studied was observed in heterozygotes than in homozygotes. small and similar variability occurred in hematocrit value and beta-globulins while higher variability occurred in body weight and gamma-globulins. 3. in common voles the faster migrating e system of ... | 1982 | 6181932 |
| serum gamma-globulin concentration in different stages of sexual activity in females of common vole, microtus arvalis, pall. | 1. in young and adult females of common vole low gamma-globulin levels at the greatest individual variability in the estrous phase were observed. 2. in natural population when the nonactive females were probably not under hormonal suppression (northern poland, late summer) they had significantly higher level of gamma-globulins than pregnant, lactating and post partum ones. 3. it is suggested that decreases of gamma-globulin concentration may be an important physiological consequences of hormonal ... | 1982 | 6174267 |
| [induction of dietetic diabetes in microtus arvalis pallas and its developmental mechanism]. | in microtus arvalis pallas, new born voles were fostered to icr mice and supplied with pellets for mice after weaning. a high concentration of glycosuria was shown in about 50% of the voles and continued for over ten weeks. concentrations of blood glucose and plasma ffa iun glycosuric voles were three or four times as high as those in normal controls. the fermentation ability and ph lowered in the esophageal sac, and comparatively large amount of starch existed in the pyloric stomach of the glyc ... | 1983 | 6363103 |
| influence of photoperiod on morphological parameters, androgen concentration, haematological indices and serum protein fractions in common vole (microtus arvalis, pall.). | 1. in male voles developed under three different photoperiods (l:d = 24:0, l:d = 18:6, l:d = 6:18) the following results were obtained. 2. higher variability of most of the parameters (except testes weight and protein fraction levels) was observed in young males. hormonal synchronization of parameters studied in adult voles was discussed. 3. sexual activity measured by morphological symptoms was related to increase of body and testes weights, rbc count, alpha 2- and gamma-globulin levels. there ... | 1983 | 6131786 |
| [detection of the tularemia zoonosis in the territory of the kartlian plain]. | the natural focus of tularemia was found to cover the whole territory of the kartlian plain. epizooty occurred mainly among common voles with the involvement of insectivorous voles. hard ticks, gamasids and fleas infected with francisella tularensis were detected. rodents highly sensitive to tularemia can be affected by this infection. water rats were not involved into the enzootic process. further studies are necessary for the final solution of this problem. | 1983 | 6225274 |
| [erysipeloid as an occupational disease of workers in shoe enterprises]. | an outbreak of erysipeloid among the workers of a shoe factory is described. the spread of infection occurred due to contact with infected raw materials, which was confirmed by the isolation of erysipelotrix rhusiopathiae from washings made from chrome and russia leather supplied by different tanneries, as well as from casein glue. the raw materials could be additionally infected by rodents, in particular by common voles; the above-mentioned infective agent had been repeatedly isolated from thes ... | 1983 | 6229115 |
| [experimental tick-borne rickettsiosis in murine rodents]. | the comparative study of the duration and level of rickettsiemia in wild rodents, natural carriers of rickettsiosis, after their experimental infection with rickettsia sibirica has been carried out. all those species under study (common voles, meadow mice and great gerbils) have been found to be faintly susceptible to this infective agent. large infective doses produce no visible signs of the disease in these animals, rickettsiemia for a short time and its level is not high. great gerbils have b ... | 1983 | 6342312 |
