Albendazole induces oxidative stress and DNA damage in the parasitic protozoan Giardia duodenalis
The control of Giardia duodenalisinfections is carried out mainly by drugs, among these albendazole (ABZ) is commonly used. Although the cytotoxic effect of ABZ usually involves binding to β-tubulin, it has been suggested that oxidative stress may also play a role in its parasiticidal mechanism. ...Read more -
