摘要
以含4%鸡血清的营养琼脂为培养基,进行了铁螯合剂2,2’-联吡啶对禽多杀性巴氏杆菌C48-3株的抑菌试验。结果表明,对于含4%鸡血清的营养琼脂培养基,铁螯合剂2,2’-联吡啶的合适添加量为200μmol/L。
Nutritious agar supplemented with 4% chicken serum was used as culture media. Suppressive effect of iron-chelator 2,2＇-dipyridyl on pasteurella multocida strain C48 -3 was studied in order to find an easy method to confirm the appropriate concentration of iron -chelator supplemented in a specific culture media to induce expression of cross-protective factor （CPF） by pasteurella multocida. The result indicated that with this method, an appropriate concentration of iron-chelator could be found out for specific culture media to induce expression of CPF. As for nutritious agar culture media supplemented with 4% chicken serum, the appropriate concentration of 2,2＇-dipyridyl was 200 μmol/L.
