| [environmental hygienic aspects of echinococcosis]. | a literature review on the current situation of echinococcosis in central europe is given. the only final host for echinococcus granulosus in this region ist the dog. the infection rate of dogs with e. granulosus in central europe is less than 1%. according to meat inspection statistics in germany less than 0.008% of sheep, pigs and horses carry larval stages of e. granulosus. parasitologically confirmed is the occurrence of a cattle-dog strain, the cysts of which were found in 0.26% of slaughte ... | 1992 | 1516550 |
| [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 ... | 2002 | 12677686 |
| genetic clustering of borna disease virus natural animal isolates, laboratory and vaccine strains strongly reflects their regional geographical origin. | the aim of this study was to gain more detailed insights into the genetic evolution and variability of borna disease virus (bdv). phylogenetic analyses were performed on field viruses originating from naturally infected animals, the bdv vaccine strain 'dessau', four widely used laboratory strains and the novel bdv subtype no/98. four regions of the bdv genome were analysed: the complete p40, p10 and p24 genes and the 5'-untranslated region of the x/p transcript. bdv isolates from the same geogra ... | 2005 | 15659758 |
| spatial distribution of bluetongue surveillance and cases in switzerland. | swiss bluetongue surveillance from mid 2007 to mid 2008 was a combination of monthly bulk milk testing of 200 cattle herds in zones of higher risk for vector presence and intensification of passive clinical surveillance. the spatial scan statistic and moran's i statistic were used to determine clustering of surveillance data. the results show a high level of surveillance intensity for bt in switzerland in 2007. in the region encompassing the cantons of aargau, basel-landschaft, basel-stadt and s ... | 2008 | 18979419 |
