Genetic and Transmission Analysis of Helicobacter pylori Strains within a Family1
Figure 4

Figure 4. Relationships and genetic transfer hypotheses for the hspA and glmM alleles from Helicobacter pylori strains infecting members of the family. The phylogenetic trees based on hspA (left) and glmM (right) sequences were built by the maximum-likelihood method. The hspA sequences shown here originate from the same 47 strains from which the glmM sequence was determined. The names given to the sequences for family genes correspond to the name of the family member followed by the allele number. Dashed lines suggest coevolution of genes. Solid lines suggest genetic transfer.
