Why is it more difficult to treat fungal infections than bacterial infections in humans?
A) Fungi are larger organisms than bacteria and thus require stronger drugs to stop an infection.
B) Most fungi are multicellular and thus the drugs required to treat a fungal infection must be able to kill several types of cells; bacteria, on the other hand, are unicellular and thus simpler to kill.
C) Fungal and animal cells and proteins are similar. Thus, drugs that disrupt fungal cell or protein function may also disrupt human cell or protein function.
D) Fungi are able to mutate more quickly than bacteria, so they quickly develop resistance to antifungal drugs.
