Abstract

PURPOSE:To provide the subject preventive and remedy containing a thiamulin derivative as an active component, exhibiting excellent antibacterial activity against bacteria of genus Renibacterium such as streptococci and free from cross-resistance between various conventional antibiotic substances. CONSTITUTION:The objective agent contains thiamulin or a thiamulin derivative selected from acid addition salt and quaternary salt of thiamulin, e.g. thiamulin fumarate, as an active component. The thiamulin derivative can be synthesized by the chemical modification of a precursor pleuromutilin which is a diterpene antibiotic substance derived from the filtrate of culture liquid of Pleurotus mutilus, The agent is administered in the form of powder, liquid, feed, etc., preferably by mixing with a diluent (e.g. starch or salt), excipient, etc., at a dose of preferably 1-500ppm. It is useful for the prevention and remedy of bacterial disease of fish such as streptococciosis and bacterial kidney disease.
