云南省家、野两型鼠疫菌营养需求的比较试验

Comparison of Nutrition Requirement Between Rat Plague Strains and Wild Rodent Plague Strains in Yunnan

目的 比较云南省家、野两型鼠疫菌的营养需求。方法 采用固体平皿法 ,对云南省 3 2株家、野两型鼠疫菌进行谷氨酸、苯丙氨酸营养需求研究。结果 2 1株家鼠鼠疫菌株中有 19株对谷氨酸半依赖 ,2株对谷氨酸不依赖 ,2 1株均为苯丙氨酸依赖 ;11株野鼠鼠疫菌株中有 3株对谷氨酸半依赖 ,8株对谷氨酸不依赖 ,11株均为苯丙氨酸依赖。结论 云南省家、野两型鼠疫菌在营养需求上有交叉性。

Objective To compare nutrition requirement between rat plague strains and wild rodent plague stains in Yunnan. Method、 We selected 32 strains of rat plague and wild rodent plague to compare their nutrition requirement about glutamic acid and phenylalnine. Result\ 19 strains were semi dependent on glutamic acid and 2 strains independent on glutamic acid in 21 rat plague strains, all of the rat plague strains were dependent of phenylalanine. 3 strains were semi dependent on glutamic acid and 8 strains independent on glutamic acid in 11 wild rodent plague strains, all of the wild rodent plague strains were dependent on phenylalanine. Conclusion There was intercrossing in the nutrition requirement between rat plague strains and wild rodent plague strains in Yunnan.
