Figure 1.

Dendrogram constructed from the concatenated sequences of 7 multilocus sequence typing (MLST) loci. Patient and animal isolates from the city of Pelotas are presented as well as two reference strains (L1-130 and 5621). Branch length is displayed next to each branch. The evolutionary distances were computed using the maximum composite likelihood method and are shown as the number of base substitutions per site. The sequences used to construct this dendrogram were retrieved from http://leptospira.mlst.net/portable/portable.xls and concatenated on http://leptospira.mlst.net/sql/concatenate/default.asp.
