Neighbor-joining tree showing the phylogenetic relationship between 16S rDNA sequence of the bacterial isolate S33 (taxonomically designated as Pseudomonas aeruginosa) and other 16S rDNA sequences belonging to closely related bacteria. Hits are expressed by their accession numbers in international nucleotide databases. Arrow indicates P.
aeruginosa strain EGYII. Phylogenetic tree was constructed via Geneious R9.0.4 software. Numbers on branch nodes represent bootstrap values (100 re-samplings)
