[Structural changes in brucella chemical vaccine after gamma-irradiation]

It was shown that gamma-irradiation of Brucella strain chemical vaccine stimulated phospholipid peroxidation therein: the content of extractable total phospholipids in the exposed vaccine decreased mainly due to diminution of phosphatidylcholines and phosphatidyl-ethanolamines. A relative content of high- and low-molecular weight protein components increased in the gamma-irradiated vaccine.
