Cluster analysis and antibiotic susceptibility of the different S. marcescens PFGE profiles obtained in this study. P1-P7: Profiles 1 to 7; P3*: Profile 3 obtained from the blood of the infants suffering bacteriemia. The cluster analysis was performed using the UPGMA method based on Dice similarity coefficient. Results of the antibiotic susceptibility assays are expressed by percentage of resistance using a color scale. AMC, amoxicilin/clavulanic acid; TZP, piperacillin/tazobactam; CXM, cefuroxime; CXM A, cefuroxime; FOX, cefoxitin; CTX, cefotaxime; CAZ, ceftazidime; FEP, cefepime; ETP, ertapenem; IPM, imipenem; AN, amikacin; GM, gentamicin; NA, nalidixic acid; CIP, ciprofloxacin; TGC, tigecycline; SXT, trimethoprim/sulfamethoxazole
