Prevalence and Genetic Characterization of Carbapenem- and Polymyxin-Resistant Acinetobacter baumannii Isolated from a Tertiary Hospital in Terengganu, Malaysia
Figure 1
Dendrogram of the 54 A. baumannii isolates from Hospital Sultanah Nur Zahirah (HSNZ) using unweighted pair group arithmetic means methods (UPGMA) from ApaI PFGE profiles. The dotted vertical line indicates the cutoff point of 80% similarity. The sources of isolation for the A. baumannii isolates are as indicated (wound, W; pus, P; endotracheal secretion, ES; skin, S; urine, U; blood, B). The MIC values for imipenem (IMP), meropenem (MEM), and polymyxin B (PB) for the isolates are shown as are their susceptibility states (resistant, R; intermediate, I; susceptible, S) according to CLSI (2012) [20]. PCR detection results for are also indicated (“+” for present; “−” for absent). The different clusters at 80% similarity are arbitrarily designated (A)–(E).
