Objective To assess the influence of cysticercus cellulosae cell vaccine on immunization in pregnant sows,piglets with maternal antibody and normal piglets.Mothods\ To measure serum antibody by ELISA method and determine the immunized results of different experimental pigs.Results\ Antidody titer of pregant sows reached a titer of 1:20480.Piglets possessed maternal antibody showed a near the effective titer 1:2560.Giving an additional immunization after birth at proper time,the antibody level can be further raised shortly.Conclusion\ The maternal antibody from pregnant sows immunized by Cysticerus cellulosae cell vaccine can be transmitted to piglets,making them possessing congenital immunity and resistant to invasion of Cysticercus cellulosae eggs.Immunization of normal piglets with the same vaccine induces an effective antibody level much slowly.
