Kanamycin (a mixture of kanamycin A, B and C) is an aminoglycoside bacteriocidal antibiotic, available in oral, intravenous, and intramuscular forms, and used to treat a wide variety of infections. It is effective against Gram-negative bacteria and certain Gram-positive bacteria. Aminoglycosides work by binding to the bacterial 30S ribosomal subunit, causing misreading of t-RNA, leaving the bacterium unable to synthesize proteins vital to its growth. Serious side effects include tinnitus or loss of hearing, toxicity to kidneys, and allergic reactions to the drug. Mixing of an aminoglycoside with beta-lactam-type antibiotics (penicillins or cephalosporins) may result in a significant mutual inactivation. Even when an aminoglycoside and a penicillin-type drug are administered separately by different routes, a reduction in aminoglycoside serum half-life or serum levels has been reported in patients with impaired renal function and in some patients with normal renal function.

Sulfomyxin is an antibacterial sulfonamide. It is intended for use in chickens and turkeys as an aid in the treatment of disease caused or complicated by E. coli, such as colibacillosis and complicated chronic respiratory disease.

Butirosin is water-soluble aminoglycosidic antibiotic complex which is active against both Gram-positive and Gram-negative bacteria. Butirosin is less toxic than neomycin and shows a good antibacterial activity, including Pseudomonas aeruginosa, which is resistant to neomycin, ribostamycin and kanamycin.
