4 simultaneous Markov chains over 2 million generations, sampled every 100 generations, and ended with a calculation of a 50% majority rule consensus tree. On the phylogenetic tree, sequences of Estonian isolate group together with those of other E. multilocularis isolates from different countries and were clearly separated from those of all other species (data not shown). The results of geneti...
