Common Fish Drugs 3
Furans are synthetic broad-spectrum antibiotics, many kinds, but only 3~4 kinds are used to prevent and control aquatic diseases. The basic structure of furans is a furan ring with a nitro group attached to the fifth carbon atom. It has strong antibacterial effect. At low concentration, it can inhibit the biological reproduction of various Gram-positive bacteria and negative bacteria; at high concentration, it has bactericidal effect. General bacteria are not resistant to furans, even if they are resistant to sulfonamides and antibiotics.
