要旨

Molecular fingerprinting procedures including random amplified polymorphic DNA-PCR (RAPD), repetitive extragenic palindromic PCR (rep-PCR) with REP, ERIC, and BOX primers and multilocus enzyme electrophoresis (MLEE) were used for genotypic characterization of 16 P. stutzeri strains originally isolated from marine, waste water, clinical and soil samples. A distinct genotype of each strain and overall great genotypic diversity were found within P. stutzeri. Cluster analysis (UPGMA) of the electrophoretic patterns of all PCR-based methods used resulted in concordant grouping of 8 strains. With the other strains conflicting clustering was noticed. The variability of clustering in PCR-based analyses suggested the occurrence of chromosomal rearrangements. When RAPD-, rep-PCR and MLEE fingerprints were used in a cluster analysis of combined electrophoretic patterns, the P. stutzeri strains could be differentiated into seven distinct genotypic groups. These results supported the subdivision of the species in several genomovars and reproduced, with higher resolution, the strain grouping after 16 rRNA phylogenetic reconstruction. The combined use of several fingerprint-based genotypic analyses results in higher resolutive strain clustering by UPGMA than each of the single ones analyzed separately. Additionally, this combination of individual typings proved to be reliable of the determination of the great genotypic diversity and relationships among the P. stutzeri strains.
