TRANSMISSIBLE GASTROENTERITIS OF SWINE VIRUS STRAIN FOR PRODUCTION OF DIAGNOSIS AND VACCINE PREPARATIONS Russian patent published in 2005 - IPC

Abstract RU 2266327 C1

FIELD: veterinary virology and biotechnology.

SUBSTANCE: transmissible gastroenteritis of swine virus strain (TGSV) was isolated by sequential passages on SPEV (swine embryo kidney cell) and other cell cultures. Said virus strain is most effectively cultivated in 3-4-day monolayer of SPEV cells, obtained in roll-tube vessel, wherein after cultivation for 24-30 h infective activity level is 7.5 lg TCD50/cm3. Strain survives starting characteristics for 18-month storage and for 9-10 passages (observation time) on SPEV cell culture.

EFFECT: TGSV strain with high biological, antigenic and immunogenic activity useful in production of high-specific and sensitive diagnosticums and high-immunogenic and harmless inactivated vaccine preparations.
