Abstract

The invention belongs to the technical field of veterinary drugs, and discloses an application of theaflavin in preparation of a drug for resisting avian pathogenic bacteria. The applicant discovers that theaflavin has the effects of inhibiting the growth of duck-origin chicken bacilli and avian pasteurella and killing the duck-origin chicken bacilli and avian pasteurella, the minimum inhibitory concentration of theaflavin to the duck-origin chicken bacilli is 128 mu g/ml, the minimum bactericidal concentration of theaflavin to the duck-origin chicken bacilli is 512 mu g/ml, the minimum inhibitory concentration of theaflavin to the avian pasteurella is 512 mu g/ml, and the minimum bactericidal concentration of theaflavin to the avian pasteurella is 512 mu g/ml. The toxic and side effects of vaccines, chemical drugs and antibiotics and potential food safety hazards are overcome, and wide application prospects and development values are achieved in the fields of food processing, medicine and breeding industry.

Description

technical field [0001] The invention belongs to the technical field of veterinary medicines, and in particular relates to the application of theaflavins in the preparation of medicines against avian pathogenic bacteria. Background technique [0002] Pasteurella avian is an opportunistic pathogenic bacterium belonging to the genus Pasteurella of the Pasteurella family, which causes the infection of 3-4 month-old rearing poultry and laying poultry, with a mortality rate of 20%-30%. The serotypes of Pasteurella can be divided into five types: A, B, D, E, and F according to the capsular antigen, among which A and F are often the dominant serotypes isolated from sick and dead birds. In addition, the duck-derived Gallibacterium gallis is an opportunistic pathogenic bacterium of the Pasteurellaceae family Gallisbacterium genus. threaten. [0003] The focus of control of poultry Pasteurellaceae diseases is mainly on prevention and antibiotic treatment. Due to the limited protecti...
