Evidence for positive selection on Mycobacterium tuberculosis within patients.

abstract：BACKGROUND:Specific host-parasite systems often embody a particular co-distribution phenomenon, in which the parasite's phylogeographic pattern is dependent on its host. In practice, however, both congruent and incongruent phylogeographic patterns between the host and the parasite have been reported. Here, we compared ...
