Figure 1 Distribution of PFGE types in community and university hospitals (Basel, Bern, Geneva, Lausanne and Zurich) (one strain per case). The four predominant clones (WCH, GE1, GE2 and GE3) are represented by their major type (1, 9, 40 and 57, respectively) and their subtype (letters). All the other types are unique PFGE patterns.
