Dendrogram obtained by UPGMA analysis of the selected Pseudomonas isolates using 208 (top) and 272 (bottom) primers, based on RADP profile (right). Genetic distances were presented with numbers placed on the branches. Rectangles are representing the isolate grouping according to obtained RAPD patterns

Phylogenetic relationships of Pseudomonas aeruginosa clinical isolates from all 12 RAPD272 clusters based on the sequence of 16S rRNA. Phylogenetic tree was constructed by the neighbour-joining method and the distances were calculated with the Kimura two-parameter model. Bootstrap values are given for each node, with 1000 replicates. Stenotrophomonas maltophilia was used as an outgroup. The horizontal bar indicates a genetic distance of 0.02
