METHOD FOR PREPARING CATTLE VIRAL DIARRHOEA VACCINE Russian patent published in 2013 - IPC A61K39/12 A61P31/12 C12N7/00 

Abstract RU 2502522 C1

FIELD: medicine.

SUBSTANCE: invention refers to veterinary virology, microbiology and biotechnology and may be used in developing the agents for specific prevention, particularly for preparing cattle viral diarrhoea vaccine. To improve the quality of an end product by using an oxidant solution as an inactivating agent prepared by the electrolysis of sodium chloride solution, as well as to activate the method for preparing the cattle viral diarrhoea vaccine involving preparing a virus-containing material of the cattle viral diarrhoea vaccine strain, infecting a continuous cell culture with the virus-containing material, culturing the cattle viral diarrhoea virus, collecting a virus-containing fluid, inactivating and preparing the end product in the liquid form, with the cattle viral diarrhoea virus being inactivated by the oxidant solution prepared by electrolysis of 10.0-20.0% sodium chloride with the electrolysis carried out to pH 7.0-8.0, oxidant concentration 0.7-0.9% and redox potential +1000±50 mV; the processing is one-staged with the active chlorine content Cax=400-600 mg/l for 60-70 min with inactivating agent consumption 4.5-5.0 cm3 per 0.8-1.0 l of the virus-containing fluid.

EFFECT: higher quality of the end product.
