Enzymatic modifications of aminoglycosides result in high-level resistance in numerous bacterial species. However, the data on this aspect are elementary in our country. The present study was therefore designed to determine resistance rates and patterns, and to find out the prevalent aminoglycoside modifying enzymes (AMEs) in clinical isolates of Pseudomonas aeruginosa from hospitalized burn patients. ⋯ Markedly high resistance to tobramycin and amikacin was noted in the present study. AAC(6')-I was the most common AME and was inferred to be plasmid encoded in R-plasmid harbouring isolates. This is among the premier reports regarding the aminoglycoside resistance due to AMEs especially plasmid encoded, in P. aeruginosa from India. Further studies are required from different parts of the country to findout the prevalence of aminoglycoside resistance due to AMEs in P. aeroginosa isolates.
