Table 2.

Antibiotic resistance patterns of Pseudomonas aeruginosa strains and their relationship with prior antibiotic exposition and PFGE patterns

^*Only one strain of Pseudomonas aeruginosa showed different PFGE patterns.

PFGE: pulsed field gel electrophoresis; COPD: chronic obstructive lung disease; CTx: cefotaxime; Cep: cephalosporines; AG: aminoglycosides; Cip: ciprofloxacin; Amp: ampicillin; Caz: ceftazidime; GM: gentamycin; Amk: amikacin; IMP: imipenem; Sxt: sulfomethoxazole; Mer: meropenem.

R-S means that the results of the susceptibility test were changed from resistant to sensitive to antibiotics and S-R means vice versa.
