Isolation and structure of a new integron that includes a streptomycin resistance gene from the R plasmid of Pseudomonas aeruginosa

Abstract

A new integron, located on the R plasmid of Pseudomonas aeruginosa, was isolated in Japan. This integron was made up of two conserved segments (5′- and 3′-conserved segments) and a single streptomycin resistance gene as a gene cassette. The structure of this integron resembles that of integron InC, the existence of which was postulated by Bissonnette and Roy (J. Bacteriol. 174, 1248–1257, 1992).
