Brucella melitensis, mainly responsible for human brucellosis, is considered as biological warfare. Being intracellular in nature Brucella induces oxidative stress due to bacterial invasion in organs like spleen and lymph nodes. The present study was aimed toevaluate the specific oxidative stress responses in erythrocytesand tissues induced byintranasal inoculation of killed Brucella whole cell protein antigen coupled with sodium acrylate nanoparticle adjuvant. Glutathione mediated nonenzymic antioxidant defense system and catalase have been observed to play a critical role in intracellular antioxidant defenses in vaccinated animals and also in maintaining an excellent milieu to induce an active immune potential. The antioxidant defenses in erythrocytes, liver, kidneys, lungs and spleen of vaccinated mice also maintained excellent redox homeostasis required for quality and effective protection without inflammatory pathophysiology.
