For example, copper treatment has been found to modulate in vitro murine macrophage elimination of Escherichia coli [20, 21]. An effect that was inhibited by the application of antioxidants, suggesting that copper modulates the generation of bactericidal reactive oxygen species (ROS) by macrophages....
During partial roasting, CuFeS(2) is first converted to Cu(2)S and FeS. Further, as iron is more reactive than copper, FeS is preferentially oxidised to FeO. This partial roasting of chalcopyrite produces Cu(2)S and FeO. CuFeS(2) + O(2) overset (Delta)

Zinc (Zn) is an essential trace element in living organisms and plays a vital role in the regulation of both microbial virulence and host immune responses. A growing number of studies have shown that zinc deficiency or the internal Zn concentration does
