Molecular characterization of blaNDM-1 in a sequence type 235 Pseudomonas aeruginosa isolate from France.

abstract：:Recently, strains of Neisseria gonorrhoeae have been isolated which are highly resistant to tetracycline (MICs of 16 to 64 micrograms/ml). This resistance was due to the acquisition of the resistance determinant tetM, a transposon-borne determinant initially found in the genus Streptococcus and more recently in Mycopl...
