Tammycin fumarate is a kind of bacteriostatic antibiotic belonging to the class of amphorin. It is a derivative of AMphorin, but it also has bactericidal effect on sensitive bacteria at very high concentration. Like macrolides, tammycin fumarate binds via Chemicalbook to the ribosomal 50S subunit, thereby inhibiting bacterial protein synthesis. This product has good antibacterial activity against many gram-positive bacteria including most staphylococcus and streptococcus (except group D streptococcus), many mycoplasma and treponema dysentery.

Tammycin fumarate is a bacteriostatic antibiotic belonging to the truncated pleurotin class, but it has bactericidal action against sensitive bacteria at very high concentrations. Like macrolides, tammycin fumarate inhibits bacterial protein synthesis by binding to the ribosomal 50S subunit. This product has good antibacterial activity against many gram-positive bacteria including most staphylococcus and streptococcus (except group D streptococcus), many mycoplasma and treponema dysentery. This product can be mixed with aureomycin 1:4 to treat bacterial enteritis, bacterial pneumonia, treponema dysentery, mycoplasma pneumonia, bronchial septicemia bordetella and pasteurella multocida pneumonia caused by mixed infection.

Application: for the treatment of swine pneumonia caused by Actinobacillus pleuropneumoniae and pig blood dysentery caused by treponema. As a drug additive in pig feed, it can promote weight gain. It is also effective for chronic respiratory tract disease of chicken, mycoplasma pneumonia of pig and synovitis of chicken staphylococcus.
