Genome sequencing of Pseudomonas aeruginosa strain M2 illuminates traits of an opportunistic pathogen of burn wounds.

ABSTRACT: Pseudomonas aeruginosa is a Gram-negative nosocomial pathogen and one of the most prevalent organisms isolated from burn wounds worldwide. Pseudomonas aeruginosa strain M2 (O5 serotype, type B flagella) is utilized for examining the murine model associated with burns. Pseudomonas aeruginosa M2 is similar in lethality to common laboratory P. aeruginosa strains when infecting CD-1 mice. Conversely, we recently showed that, relative to these strains, P. aeruginosa M2-infected mice are more susceptible to sepsis and demonstrate a 6-log reduction in LD50 from subcutaneous infection at the infection site directly after 10% total body surface area burn. To better understand this striking phenotypic difference from other P. aeruginosa strains employed in burn models, we sequenced the P. aeruginosa
