Clustering of mutations affecting central pathway enzymes of carbohydrate catabolism in Pseudomonas aeruginosa.

abstract：:A conjugation system initially discovered in beta-lactamase-producing gonococci mobilized small non-selftransmissible R plasmids encoding beta-lactamase (penicillinase) production into other gonococci, Neisseria, and Escherichia coli. This conjugation system was mediated by a separate selftransmissible plasmid of 23.9...
