We conducted phylogenetic and epidemiologic analyses to determine sources of outbreaks of highly pathogenic avian influenza virus (HPAIV), subtype H5N1, in poultry holdings in 2007 in Germany, and a suspected incursion of HPAIV into the food chain through contaminated deep-frozen duck carcasses. In summer 2007, HPAIV (H5N1) outbreaks in 3 poultry holdings(More)
Riems FMD two-component oil emulsion vaccine was subcutaneously applied (5 ml) under field conditions to 855 store pigs of different age groups (trivalent--O1, A5, C). It produced early onset of lasting strong immunity against the three above FMD virus types. General condition of the animals and their body weight development were not adversely affected.(More)
Composting of poultry carcasses represents an alternative method for disposal in case of an outbreak of an epizootic disease. Two composting experiments, each with a different construction of the compost pile, were carried out in a stable. In the first experiment two layers of turkey carcasses were formed. This compost pile covered with straw was directly(More)
Further observations concerning the previously described RiV-particles are reported. They were isolated from a diploid cell line of bovine origin, embryonal duck fibroblasts and BHK-21 cells. A protective effect against foot-and-mouth-disease virus in guinea pigs could be observed following inoculation with the RiV-preparation of bovine origin. All 3(More)
Three peptides of main epitope of FMD virus O1-Kaufbeuren, VP1 (16, 21, 31), were found to induce in the 130-160 sequence range, in free and/or carrier-bonded form, virus-neutralising antibodies in guinea pig, rabbit, mouse, swine, and cattle. Five carrier proteins were tested, with thyroglobulin, next to keyhole limpet hemocyanin (KLH), being most(More)
The influence of the peptide diacetylsplenopentin (SP5) on an early protection of guinea pigs against foot-and-mouth disease (FMD) was investigated. 80% protection was achieved if SP5 was applied in a dose of 2 mg one day before challenge with FMD virus (FMDV) type O1 Lausanne strain. In comparison with this a conventional commercial adsorbate vaccine(More)
Swine plays a very particular role in FMD epizootiology. It is, therefore, absolutely necessary to have highly effective vaccines available for this species at all times. They have to ensure early buildup of long-lasting strong immunity even after one single application. Since the effectiveness of conventional adsorbate vaccines had proved to be(More)
