Pseudomonas aeruginosa clinical and environmental isolates constitute a single population with high phenotypic diversity.

ABSTRACT:

Background

Pseudomonas aeruginosa is an opportunistic pathogen with a high incidence of hospital infections that represents a threat to immune compromised patients. Genomic studies have shown that, in contrast to other pathogenic bacteria, clinical and environmental isolates do not show particular genomic differences. In addition, genetic variability of all the P. aeruginosa strains whose genomes have been sequenced is extremely low. This low genomic variability might be explained if clinical strains constitute a subpopulation of this bacterial species present in environments that are close to human populations, which preferentially produce virulence associated traits.

Results

In this work, we sequenced the genomes and performed phenotypic descriptions for four non-human P.
