Figure 1. Phylogenetic tree of Aeromonas isolates recovered from diarrhea patients.

The tree shows the relationships based on partial sequences of rpoD gene of type strains of Aeromonas species and the isolates from the current study. The sequence alignments were performed using the CLUSTAL W program, and the tree was generated using the neighbor–joining method with Kimura 2 parameter distances in MEGA 4.1 software. Bootstrap values (from 1,000 replicates) greater than 50% are shown at the branch points. The bar indicates 2% sequence divergence.
