Multilocus sequence typing analysis of the whole genome sequences of the Clostridium difficile isolates. (A) Frequency of sequence type (ST) identification by MLST clade in the studied isolates (n = 53). (B) Frequency of ST identification by population: intrahospital (IH in red; n = 32) and community (CO in blue; n = 21). (C) Phylogenetic reconstruction from the alignment of the concatenated sequences of the seven genes used for MLST. The red dots indicate well-supported clusters (bootstrap ≥90.0%). The coexistence of ST events, defined as the simultaneous identification of two STs in isolates established from the same patient, are marked on the right.
