Application
Biofilm research
Effect of tobramycin on biofilm cells in Pseudomonas aeruginosa has been reported.1,2) The bacterial cells in biofilm formed on catheter material exhibited highly resistance to the antimicrobial agent and planktonic cells were killed by the agent.1) Study using in vitro chemostat system showed also that cells in old biofilm were more resistant to tobramycin in comparison with cells in young biofilm.2)

Tobramycin: An Aminoglycoside Antibiotic Active Against Pseudomonas Aeruginosa
Tobramycin is an aminoglycoside antibiotic derived from Streptomyces tenebrarius, and is similar in structure to gentamicin [G0383]. Tobramycin interacts with the 30s and 50s subunit of prokaryotic ribosomes, and then it inhibits bacterial growth by inhibiting protein synthesis. Tobramycin is more active than gentamicin against Pseudomonas aeruginosa and active against many gentamicin resistant strains. Recently, inhaled tobramycin is effective in treating chronic Pseudomonas aeruginosa lung infection in cystic fibrosis. (The product is for research purpose only.)
