METHOD OF PREPARING BROAD SPECTRUM VACCINE FOR PREVENTING AVIAN COLIBACILLOSIS

摘要

The present invention discloses a method of preparing a broad spectrum vaccine for preventing avian colibacillosis, including recombining the tsh gene, which has an adhesive attraction effect, with E.coli BL21 (DE3); the resulting vaccine may preferentially bind to the corresponding receptors on avian body cells, resulting in there being no receptors to bind to the pathogenic E.coli, thus decreasing morbidity rates among avians.
