Vibri parahaemlyticus is cnsidered as a ptentially pathgenic bacteria, the causative agents f the gastrenteritis. Accrding as the LPS antigens were injected int laying hens in rder t prduce antibdies against Vibri parahaemlyticus in egg ylk. After chickens were immunized fur times in 2 weeks interval and three times bster in 2 weeks interval, the prfile f antibdy prductin was examined by ELISA. The prductin f antibdy in egg ylk was started in 1 week after the first immunizatin, reached peak in 7 weeks and maintained until 13 weeks later. The antibdy titre in serum shwed similar tendency as IgY. N significant difference in antibdy titre when the titre cmpared t water diluted IgY and cmmercial IgY kit. Purified IgY reacted with nly Vibri parahaemlyticus, but ther Vibri species and fd-brne pathgenic bacteria. In cnclusin, we shwed that it is pssible t btain a high antibdy titre in chicken with quite lw amunts f LPS antigen. These results suggested that egg ylk antibdies culd be a gd surce fr prductin f specific antibdies t pathgenic bacteria inducing epidemic gastrenteritis.
