摘要：

将分离鉴定的无乳链球菌用0.4%的甲醛灭活，加弗氏完全佐剂制成灭活全菌苗，对牛蛙进行注射免疫。通过测定受免牛蛙血清中凝集抗体效价，总蛋白、免疫球蛋白的测定及免疫保护率的测定，探讨疫苗的免疫应答状况。研究结果表明，无乳链球菌全菌疫苗能够提高牛蛙的血清抗体水平及总蛋白、免疫球蛋白含量。此外，无乳链球菌全菌苗对牛蛙抗人工感染也具有较好的免疫保护作用。因此，将无乳链球菌全菌苗用于牛蛙链球菌病的防治具有广阔的发展前景。

Abstract:

The isolated and identified Streptococcus agalactiae inactivated with 0.4% formaldehyde, made inactivated whole bacteria vaccine with CFA, immunity Bullfrog by injections. By measuring serum agglutinate titer, total protein, the determination of immunoglobulin and immune protection rate, determinate of status of the vaccine immune response. The results showed that all bacteria vaccine can improve the bullfrog serum antibody levels and total protein, immunoglobulin content. In addition, all bacteria vaccine infected bullfrog also has good resistance to the immune protective effects on the immune protection rate. Therefore, there is a potential to apply whole bacteria Streptococcus agalactiae to prevention and cure of Bullfrog suffering with Streptococcus agalactiae.
