Endemicity of Acinetobacter calcoaceticus-baumannii Complex in an Intensive Care Unit in Malaysia

Figure 2

Dendrogram of the PFGE profiles of ApaI-digested 50 ACB complex isolates using Unweighted Pair Group Method with Arithmetic Averages (UPGMA). The dotted vertical line indicates the cut-off point of 85% similarity. The different clusters at 85% similarity are arbitrarily designated G1–G4, whereby G1 is the largest group representing the most prevalent pulsotypes and its variants among the isolates.
