Protective efficacy of vaccination on E. tenella challenge

Body weight gain, cecal lesion scores, oocyst output and the percentage reduction of oocyst excretion are summarized in Table 1. The results showed that non-immunized challenged control groups exhibited significantly reduced weight gain compared with all immunized groups and the unchallenged control group chickens (p <0.05) after challenge. The cecal lesion scores of chickens immunized with r Et CHP18905 were significantly lower than those of the challenged control. The oocyst output was reduced after immunization with r Et CHP18905. Chickens immunized with r Et CHP18905 presented signifi- cantly higher percentage reduction of oocyst excretion compared with the challenged controls (p <0.05).
