- Use：
- Flumequine is a kind of synthetic second-generation, animal-specific quinolone antibacterial drugs. it is currently the only non-humans shared broad-spectrum antimicrobial veterinary drug. it is taken as the substitute product of norfloxacin. it has a strong bactericidal activity with excellent efficacy in the treatment of animal bacterial diseases. its main effect is to inhibit bacterial deoxy nucleic acid (dna) gyrase, interfering with the deoxyribonucleic acid (dna) synthesis, thereby causing failure of cell for further division, and thus playing the role of killing bacteria. it is mainly used in animal bacterial respiratory disease including e. coli, dysentery, salmonellosis, typhoid, fowl cholera, staphylococcal disease and infectious rhinitis. it can also be used for the treatment of e. coli disease, monospora disease and vibrio disease in aquatic animals with strong inhibitory effect on the aeromonas hydrophila.
