Maternal antibody parameters of cattle and calves receiving EG95 vaccine to protect against Echinococcus granulosus

Abstract

Cattle may act as hosts for the transmission of the cestode parasite Echinococcus granulosus and play a role in transmission of the parasite leading to human cystic echinococcosis (CE). The recombinant EG95 vaccine has been shown to be able to protect cattle and other intermediate host species against CE. Ideally the immunisation of bovines against E. granulosus, using EG95 vaccine, should occur early in life so as to provide maximum protection against the establishment of hydatid cysts. Maternally derived antibody from vaccinated cows may provide some protection for the neonate, but may also interfere with the active response to vaccination. Experiments were undertaken to determine the opti..
