Figure 2. Minimum spanning tree of the B. henselae MLVA profiles.

Profiles connected by a shaded background differ by a maximum of one of the five VNTR markers; regular connecting lines represent two marker differences; thick interrupted lines represent three differences. The length of each branch is also proportional to the number of differences. The colors of the branches and circles are related to the geographical origin of the detected profile. All the isolates from Spain used to build this diagram were obtained in this study. They are labeled with a thick red circle and their own profile number according to the public database (http://mlva.u-psud.fr/).
