CYTOPATHOGENIC VIRUS STRAIN BOVINE VIRAL DIARRHEA-MUCOSAL DISEASE VIRUS FOR INVESTIGATION OF CLINICS OF VIRAL DIARRHEA - CATTLE MUCOSA DISEASE AND METHOD FOR EXPERIMENTAL REPRODUCTION OF VIRAL DIARRHEA - CATTLE MUCOSA DISEASE IN CALVES

摘要

FIELD: veterinary virology.;SUBSTANCE: invention proposes the cytopathogenic strain of virus Bovine Viral Diarrhea - Mucosal Disease Virus NII KKM № V-340 for study of clinics of viral diarrhea - cattle mucosa disease, and a method for experimental reproduction of viral diarrhea - cattle mucosa disease in calves. Suspension of the proposed virus strain is administrated in the dose 4 x 10^6,5TCD_{50/0.1 ml} to virus-seronegative 3-4 months age calves by aerosol generator BG-2. Proposed viral diarrhea virus strain - cattle mucosa disease and method for infecting calves can be used for screening antiviral preparations.;EFFECT: valuable properties of strain, improved method of disease reproduction.;3 cl, 3 ex
