A rapid seamless method for gene knockout in Pseudomonas aeruginosa.

ABSTRACT:

Background

Pseudomonas aeruginosa is a model organism for the study of quorum sensing, biofilm formation, and also leading cause of nosocomial infections in immune compromised patients. As such P. aeruginosa is one of the most well studied organisms in terms of its genetics. However, the construction of gene deletions and replacements in Pseudomonas aeruginosa is relatively time-consuming, requiring multiple steps including suicide vector construction, conjugation, inactivation with insertion of antibiotic resistance cassettes and allelic exchange. Even employing Gateway recombineering techniques with direct transformation requires a minimum two weeks. METHODS: We have developed a rapid streamlined method to create clean deletion mutants in P. aeruginosa through direct transforma
