Description

technical field [0001] The invention belongs to the field of veterinary medicine, and in particular relates to a method for preparing a teramycin compound by using demethylazithromycin as a raw material. Background technique [0002] Respiratory tract infection is one of the more difficult to control infectious diseases in animal husbandry, which is seriously harmful to animal husbandry production. When the respiratory tract infection is prevalent, it will cause huge economic losses to animal husbandry production. Therefore, how to prevent and treat the respiratory tract infection of livestock such as pigs and cattle is an important research topic for veterinarians and veterinary drug workers. Because respiratory tract infections are generally multiple infections, many pathogenic factors, and complex conditions, there is currently no very effective prevention method. For respiratory tract infections in animals, while seeking biological control and environmental blocking, d...
