p Values between any two discordant pairs are shown in brackets. Statistical test used: McNemar test; association is significant at p < 0.05 and is boldfaced. Since none of the tested pseudomonal strains showed lack of susceptibility to polymyxin B, association between polymyxin B and other antibiotics could not be evaluated. R = resistance to the tested antibiotic of the cultured pseudomonal strain, S = susceptibility to the tested antibiotic of the cultured pseudomonal strain, Moxiflox = moxifloxacin, Ciproflo = ciprofloxacin, Tobra = tobramycin, Amika = amikacin, Cefurox = cefuroxamin, Ceftazid = ceftazidime, Cefazol = cefazolin, Tetracyc = tetracycline).
