Tiamulin is a semi-synthetic derivative of Pleuromutilin. It is highly active against gram-positive organisms such as
streptococci, staphylococci and against mycoplasmas and serpulina (Treponema) hyodysenteriae. A number of
Shigella, Klebsiella and E. coli are also quite susceptible to this agent. Some anaerobic species including Bacteroides
fragilis and Clostridium perfringens with no exception are sensitive to tiamulin.
