Answer:The reason for this is because fungi and their host are eukaryotic and in treatment of fungal infections drug used can also affect their host.
Explanation:
Antifungal drugs are drugs used in the treatment of fungal infections and so are antibiotics and antiviral drugs used to treat bacterial infections and viral infections respectively.
Fungi and their host are both eukaryotic and this make them closely related. They attack by colonizing and destroying the tissues of the animal host. When treating infections caused by fungi, the compounds used to kill fungi also harm the animal host because of the eukaryotic property they both possessed, this therefore set limitations to antifungal drugs. Unlike fungi, bacteria attack prokaryotic cell and also bacterial infections are systematic not superficial or topical like fungal infections.
