摘要
To understand immunization effect of pseudorabies vaccine and infection status of porcine pseudorabies （PR） in pig farms and guide prevention and control against PR, 453 copies of blood samples collected from 43 different scale pig farms in four counties （districts） of Binzhou City were detected with ELISA to investigate PRV gB antibody and gE antibody. Detection results showed that the gB antibody positive rate of sows was 75.58%, and that of fattening pigs was 68.67% ; the pig farms with positive rate higher than 70% accounted for 74.42% of total survey pig farms. The PRV gE antibody positive rates of sows and fatte- ning pigs were 25.41% and 26.67%, and the positive rates of pig farms were 46.51% and 44.33%, respectively. There were regional differences among counties （districts）.
