The quality of DNA sequences was checked and the overlapping fragments were assembled using BioEdit 7.0.5. The phylogenetic relationships between these sequences were determined with MEGA 5.0 and neighbor-joining trees were constructed from Kimura-2 parameters and bootstrap values using 250 replications. Cluster analysis, displayed as a dendrogram, was done using Gel Compar ll version 6.5 with binary data (presence/absence of bands) and bootstrap calculations over 1000 iterations.
