Description and Uses
Oxytetracycline also is one of the classic tetracyclines. It is produced by fermentation of Streptomyces rimosis and other soil microorganisms. The most hydrophilic tetracycline on the market, it has largely now been replaced by its semisynthetic descendants. It is primarily used today for IM injections.
Oxytetracycline, which has seen significant usage in plant disease control, does not contain the Cl atom but has an additional -OH group at the C5 position on the tetracycline molecule (4). Tetracyclines are widely used therapeutic agents in clinical medicine [second to penicillins in total tons used each year (5)] for bacterial respiratory, periodontal, and urogenital tract diseases (6). Oxytetracycline is also used as a feed amendment for growth promotion and as a therapeutic agent for curing diseases of agricultural animals including fish.
