Carbomycin is a complex mixture containing carbomycin A with a small portion of carbomycin B. Carbomycin is produced by Streptomyces halstedii and acts as an antibiotic. The drug was approved by FDA under the name Magna-terramycin (in combination with oxytetracycline) for the treatment of bacterial chronic respiratory diseases in chickens. Carbomycin exerts its antibacterial action by binding within the large ribosomal subunit and thus inhibiting the protein synthesis in bacterias.
