Fig. 5.

Maximum-likelihood estimation of phylogenetic relationship between named species and population representatives performed using partial topA sequences. Clusters are alternatively shaded light and dark gray. Only named species that cluster as closest relatives to population representatives are shown. Bootstrap support is shown for cases in which the value was greater than 75%. Species names followed by the NCBI GI number are provided for all sequences from NCBI. Population representatives are named using the isolate name followed by a study identifier (using a single-letter designation for the study) and population number.
