Virginiamycin?is a class of streptogramin-related depsipeptides isolated from the bacterium Streptomyces virginiae and other Streptomyces bacterial species. The virginiamycins consist of two major components,?virginiamycin M1?and?virginiamycin S1. These agents bind to and inhibit ribosome assembly, thereby preventing protein synthesis. Active against Gram-positive bacteria, these antibiotics are primarily used in veterinary practice.

Tylosin is used in veterinary medicine to treat bacterial infections in a wide range of species and has a high margin of safety.

Kebuzone (or ketophenylbutazone) is a non-steroidal anti-inflammatory drug.

Kanamycin (also known as kanamycin A) is an aminoglycoside bacteriocidal antibiotic, available in oral, intravenous, and intramuscular forms, and used to treat a wide variety of infections. Kanamycin is isolated from the bacterium Streptomyces kanamyceticus and its most commonly used form is kanamycin sulfate.
