The present invention relates to recombinantly prepared parapoxviruses which carry, in their genomes, deletions or insertions in the form of foreign hereditary information and contain hereditary information, to the preparation of such constructs and to their use in vaccines.

Parapoxviruses containing foreign DNA, their production and their use in vaccines

The invention relates to equine herpesviruses (EHV) which contain foreign DNA elements in addition to the genome sequences necessary for the replication thereof, to process for the preparation thereof and to the intermediates employed therein, and to the use thereof in vaccines against EHV infections.

Equine herpesviruses (EHV) which contain foreign DNA, process for the preparation thereof and the use thereof in vaccines

The invention relates to polynucleotides which contain pseudorabies virus sequences, in particular sequences from the gII region of PRV, in the antisense orientation, their preparation and their use.

Pseudorabies virus (PRV) polynucleotides and their use for preparing

Inducers of non-specific immunity are obtained by increasing the pH of a virus suspension of viruses which elicit non-specific immunity and then heating the pH-increased virus suspension. The pH value can be increased to between about 8 and 11 and heating is carried at temperature between about 50.degree.-60.degree. C.

Process for the preparation of inducers of non-specific immunity and
