[Method] A total of 85 fox blood samples were col- lected from four farmers in Changli County. The serum antibody titer against fox encephalitis was detected by enzyme-linked immunosorbent assay （ELISA）. The OD values were measured to determine the presence of CAV-1 antibody in samples. [Result] 93% of the 15 serum samples from Farmer 1, 86% of the 14 serum sam- ples from Farmer 2, 97% of the 30 serum samples from Farmer 3 and 92% of 26 serum samples from farmer 4 were CAV-1 antibody-positive. In summary, among the 85 serum samples from the four farmers, six were CAV-1 antibody-negative, and 79 were CAV-1 antibody-positive, namely 93% of the foxes were successfully immunized. [Conclusion] The results revealed that vaccination against fox encephali- tis in Changli was run well, but the immunization in several foxes should be strengthened.展开更多
