COMPLEX ANTIBIOTIC COMPOSITION FOR ANIMAL

摘要

PURPOSE: A complex antibiotic composition for animal is provided, which prevents and cures germ diseases of domestic animals and fishes, substitutes high cost of anti-biotic material, and minimizes remains of drug in an animals body. CONSTITUTION: The complex antibiotic composition for animal comprises of norfloxacin(NFLX) and tylosin(TYL) in the weight ratio of 1:4-4:1, desirably 1:2-2:1. The norfloxacin(NFLX) is a kind of third generation quinolone antibiotics, which inhibits DNA gyrases of a disease germ, so kills germs; which can be bound to DNA gyrases of a disease germ easily by carboxylic acid on No.3 position; and shows strong germicide effect by fluorine on No.6 position. The tylosin(TYL) inhibits translocation step of protein-synthesis by binding to a subunit of germ 50S ribosome, so obstructs protein-synthesis of a germ, and inhibits growth of a germ finally; which shows germicide action at high concentration.
