[New types of virus infections of domestic animals in the German Democratic Republic. 1. Serologic survey studies of the distribution of equine torovirus infections in the GDR].

Sera collected from 124 horses were checked by means of the serum neutralisation test against equine Bern virus. Torovirusspecific antibodies were recordable from 35 percent of all horses tested. These results are likely to suggest that toroviruses are widespread in the GDR and occur not only in horses but in other domestic animals and in man, as well.
