Use 1: As an antibacterial synergist, it can also treat poultry bacterial infection and coccidiosis.

 

Use 2: new oral broad-spectrum antibacterial drugs. The antibacterial spectrum is similar to that of sulfanilamide drugs, but the efficacy is stronger, and it is effective against a variety of gram-positive and negative bacteria. Because the bacteria will easily develop resistance to this product, it is not suitable for use as an antimicrobial drug alone. The combination of trimethoprim and sulfanilamide can enhance the antibacterial effect several times to tens of times. The product is mainly used as a synergist of sulfonamide drugs. It is generally used in a ratio of 1:5. It can also be used as a veterinary drug to treat septicemia, white dysentery, typhoid fever, cholera, secondary bacterial infection of respiratory system caused by coliform bacteria in poultry. It can also be used in the treatment of coccidiosis.
