Studies on mutagenicity of Schistosoma japonicum bivalent DNA vaccine / 中国血吸虫病防治杂志

ABSTRACT

Objective To evaluate the mutagenicity of Schistosoma japonicum bivalent DNA vaccine.Methods The mutagenicity of Schistosoma japonicum bivalent DNA vaccine was studied by Ames test,micronucleus test and chromosome aberration test.Results On the conditions of actived and unactived,Schistosoma japonicum bivalent DNA vaccine did not lead obvious increase of colony units,and the result of the Ames test was negative.Compared with the control group,there were no significant differences in the treated groups on the frequency of micronucleus in PCE or chromosome aberration.Conclusion There is no mutagenicity of Schistosoma japonicum bivalent DNA vaccine.
