In-vitro activities of quinupristin/dalfopristin and other anti-staphylococcal agents against methicillin-resistant strains of Staphylococcus aureus isolated over a 16-year period.

The results of this study suggest that the transduction of antibiotic resistance genes by wild-type phages is an additional mechanism of spread amongst strains of P. aeruginosa. The emergence of lysogenic, multidrug-resistant strains, therefore, should be closely monitored. tobramycin resistance in Pseudomonas aeruginosa with phage F 116 and AP 19, a new wild-type phage.
