Disruption of biofilm formation by the human pathogen Acinetobacter baumannii using engineered quorum-quenching lactonases.

Acinetobacter baumannii is a major human pathogen associated with multidrug-resistant nosocomial infections; its virulence is attributed to quorum-sensing-mediated biofilm formation, and disruption of biofilm formation is an attractive antivirulence strategy. Here, we report the first successful demonstration of biofilm disruption in a clinical isolate of A… CONTINUE READING
