Abstract
Abstract TRANSMISSILBE GASTROENTERITIS VIRUS IS GROWN AND PROPAGATED IN TISSUE CULTURES BY INOCULATING VIRULENT VIRUS PARTICLES INTO A FIRST TISSUE CULTURE, ALLOWING THE VIRUS TO GROW, INTRODUCING THE VIRAL PARTICLES INTO OTHER TISSURE CULTURES UNTIL A CONTINUATED VIRUS IS OBTAINED. A FINAL VIRUS CULTURE CAN BE HARVESTED AND COMBINED WITH A STABLILIZER AND FURTHER INCUBATED TO INACTIVATE THE VIRUS. SOWS AND THEIR NURSING PIGS CAN BE IMMUNIZED BY INJECTING INTO THE PREGNANT SOW BEFORE FARROWING THE VACCINE THUS PRODUCED.
