a
K, Lithuanian University of Health Sciences Kauno Klinikos Hospital; V, Vilnius University Emergency Hospital. LT3 and LT-V1 were representative isolates of clonal outbreaks in hospitals in 2010, whereas LT-11 was a sporadic isolate. Clonality was determined by PFGE-ApaI restriction analysis.
b
Antimicrobial susceptibility to MEM (meropenem), IPM (imipenem), TZP (tazobactam/piperacillin), SAM (sulbactam/ampicillin), SCF (sulbactam/cefoperazone), CAZ (ceftazidime), GM (gentamicin), AN (amikacin), CIP (ciprofloxacin), and PIP (piperacillin) was tested.
c
The 3′-conserved segment (CS) of integron was missing.
