[detection of verotoxin-producing e. coli in field isolates from domestic and agricultural animals in sachsen-anhalt].a report is given on the detection of verotoxin-producing e. coli (vtec) strains from field isolates of healthy or ill cattle (n = 141), pigs (n = 306), sheep (n = 15), cats (n = 29) and dogs (n = 25) in the region of the new federal land sachsen-anhalt. 5% of the strains isolated from cattle, 32% from pigs, 20% from sheep, 4% from dogs and 0% from cats have shown vtec. the e. coli-strains were checked for the presence of other factors of virulence, too. a good correlation (82%) was found betwee ...19947802620
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 ...200515659758
ovine coccidiosis in housed lambs in saxony-anhalt (central germany).the course of coccidiosis in lambs and the species of eimeria involved were investigated in saxony-anhalt, germany. a field study was conducted on three farms (conventional lamb-fattening farms) with 59 lambs. a total of 1092 faecal samples were taken during a period from about two to seven weeks after birth; the eimeria species involved were determined in 415 of these samples and morphometrical characteristics of oocysts of 12 eimeria spp. were recorded. subclinical to moderate clinical coccidi ...201020135910
