METHOD FOR MANUFACTURING VIRAL ANTIRABIC VACCINE FOR ORAL IMMUNIZATION I WILD CARNIVORES Russian patent published in 2005 - IPC

FIELD: biotechnology, veterinary science.

SUBSTANCE: he present innovation deals with manufacturing biopreparations for oral immunization in animals. One should grow vaccinia rabic virus, TC-80 strain in a certain passage cell culture to mix it with protective components (peptone, lactose, pectin). Mixing should be carried out at 14 : 5 : 1 ratio (viral suspension : stabilizing medium, consisting of 40% peptone solution with 8% lactose solution : 4% pectin solution, correspondingly), a semifinished product obtained after mixing should be applied onto a bait (a porous briquette) to be frozen and freeze dried for 24-30 h. The method includes decreased number of stages for manufacturing necessary vaccine being more efficient and economical. The vaccine keeps immunogenic properties for 5 d, not less at environmental temperature being up to 20 C and during storage period for 6 mo at 6-8 C.

EFFECT: higher efficiency of manufacturing.
