[malignant catarrhal fever in switzerland. 1.epidemiology].malignant catarrhal fever (mcf) is a usually fatal infectious disease of cattle with global distribution. based on the recent introduction of a diagnostic pcr assay and a competitive inhibition elisa (cielisa) epidemiological data were collected on field cases in switzerland. throughout a three-year period, an mcf incidence of 0.6@1000 was observed, with a gradient of cases from eastern to western switzerland. while the cantons wallis, vaud and geneva reported no and the remaining western canton ...200111344942
[ovine enzootic abortion: seroprevalence in switzerland using a competitive enzyme-linked immunosorbent assay (celisa)].the present study gives an overview over the seroprevalence of ovine enzootic abortion in switzerland. 639 sheep flocks out of eight cantons in switzerland were examined by a competitive enzyme linked immunosorbent assay (celisa) for antibodies against chlamydophila abortus (chlamydia psittaci serotype 1), the agent causing ovine enzootic abortion. the eight cantons included aargau, bern, zürich, appenzell-ausserrhoden, appenzell-innerrhoden and fribourg, the vallais and the graubünden. they wer ...200212677686
genetic diversity of swiss sheep breeds in the focus of conservation research.there is constant pressure to improve evaluation of animal genetic resources in order to prevent their erosion. maintaining the integrity of livestock species as well as their genetic diversity is of paramount interest for long-term agricultural policies. one major use of dna techniques in conservation is to reveal genetic diversity within and between populations. forty-one microsatellites were analysed to assess genetic diversity in nine swiss sheep breeds and to measure the loss of the overall ...200919320774
seroprevalence survey for salmonella abortusovis infection in swiss sheep flocks.between 1976 and 2003, no infections with salmonella abortusovis had been officially recorded in switzerland. since then, however, several sheep flocks were infected and suffered massive fetal losses suggesting a re-emergence of the disease. therefore, the aim of this study was to assess the epidemiological situation of s. abortusovis infection in sheep in this country. a representative serum sample collected in 2007 in the context of certifying brucella freedom included sera from 578 flocks wit ...201020870306
an important outbreak of human q fever in a swiss alpine valley.we describe an important q fever human epidemic involving 415 serologically confirmed cases in the val de bagnes (valais, switzerland) during the autumn of 1983. the ages of the 415 cases with acute q fever ranged from 8 to 82 years with a mean of 35 years, of whom 58% (240) were men and 42% (175) were women. this outbreak started about three weeks after 12 flocks of sheep (between 850 and 900 animals) descended from the alpine pastures to the valley. geographically, the epidemic reached all the ...19873301708
