Use of tannic acid in the preparation of a medicine for inhibiting haemophilus parasuis
Tannic acid is used in the preparation of veterinary preparations, which solves the problems of complex serotypes and drug resistance of Haemophilus parasuis. By inhibiting the growth of Haemophilus parasuis, it provides a safe and efficient prevention and control solution, reduces antibiotic dependence, and improves the prevention and control effect.

AI Technical Summary
In the current technology, Haemophilus parasuis has complex serotypes, limited cross-protection effect of vaccines, strong reliance on antimicrobial drugs in clinical prevention and control, and increasingly prominent drug resistance. There is a lack of novel anti-infective components with high safety and low resistance to drug induction.
Using tannic acid as the main active ingredient, veterinary preparations for inhibiting Haemophilus parasuis are prepared, including oral tablets, capsules, oral liquids, granules or injections, supplemented with pharmaceutically acceptable excipients, carriers and/or diluents, and can be combined with other veterinary clinically available drugs for the prevention and treatment of bacterial diseases in pigs caused by Haemophilus parasuis.
Tannic acid has shown clear antibacterial effects, reducing the pressure of traditional antibiotic use, improving the stability and effectiveness of swine bacterial disease control, and reducing the emergence of multidrug-resistant strains.
