豬丹毒桿菌活疫苗的安全性試驗(yàn)
[Abstract]:In order to test the safety of porcine erysipelas vaccine, the test was divided into four groups: porcine erysipelas vaccine (A1A _ 2), porcine erysipelas vaccine isolation (B1B _ 2), pig farm porcine erysipelas isolation (C _ 1C _ 2), positive reference group (D _ 1D _ 2). Negative reference group E, 9 groups, each group of bacteria liquid 2 gradient, each gradient bacteria solution inoculated 10 mice. At the same time, 30 piglets of 40 days old were injected with the vaccine to observe the growth, death, mental status and autopsy of mice and piglets. The results showed that there was no significant difference in the body weight, growth, mental status, dissection status, and no death between the vaccine-related strain Agna BX C group and the negative control group after the infection, and the results showed that there was no significant difference between the negative control group and the control group. In the positive control group, the mice developed loose hair, pile up, no food, skin redness, mental decadence and died within 72 hours after infection for 24 hours. There was no significant difference in mental state and growth between the pigs and the control group. The results showed that the porcine pigs were safe to mice with porcine erysipelas vaccine batches.
