As eukaryotic parasites will be more common in structure to the human body hence, the drugs might have adverse effects on the human body.
A large number of proteins found in the eukaryotic parasite will be similar to the proteins made by the human body. The drug taken for a eukaryotic parasite can harm the same kind of protein found in the human body.
Bacteria is a very small microorganism and has very simple machinery. The proteins formed by a bacterial cell are very few and are not as commonly related to the human proteins as the eukaryotic parasites. Hence, drugs taken for bacterial parasites would not have such adverse effects.
