Pyocin sensitivity of pseudomonas aeruginosa pretreated with antibiotics.
Strains of Pseudomonas aeruginosa exposed to subinhibitory concentrations of either polymyxin B, gentamicin, or carbenicillin were compared with untreated organisms for changes in sensitivity to pyocin. Pretreatment with polymyxin B or gentamicin resulted in a decreased sensitivity to pyocin, while carbenicllin pretreatment did not alter pyocin sensitivity.
