The recent oral immunisation trials in wild boar against classical swine fever (CSF) in Germany are described and evaluated in summary. After the first field study in Lower Saxony from 1993-1995 further immunisation trials started in Mecklenburg-Western Pomerania, Brandenburg, Lower Saxony, Baden-Württemberg and Saxony-Anhalt. The immunisation strategies and the size of the vaccination zones were different in the individual federal states. In principle, the bait vaccine based on the CSF virus strain "C" were laid out by hand. Later also the aerial distribution was carried out in selected areas of Mecklenburg-Western Pomerania. The application of baits by plane was introduced at the beginning of the immunisation measures in Saxony-Anhalt apart from the manual distribution. Up to now, the field trials show that the oral immunisation can be an additional tool for CSF control by increasing of herd immunity and reduction of the CSFV prevalence. However, the immunisation was not sufficient enough for young boars in the most field studies. Based on the evaluation of the immunisation experiments an improved immunisation procedure is recommended.
A catalogue concerning adequate concentrations of pesticides for use in patch testing is presented. These recommendations are based on author's experiences also utilizing case reports both of the GDR and of the international literature. In particular case reports are mentioned on contact dermatitis due to Metham-sodium, Dazomet, Zineb and Maneb, Benomyl, Captan, Propachlor, Phenmedipham, 2,4-D and 2,4,5-T, Dichlorvos, Parathionmethyl, Trichlorfon. The recommended patch test concentrations should be made a subject for discussion and further investigations.
