Pseudomonas aeruginosa is a ubiquitous opportunistic pathogen and one of the leading causes of healthcare-associated and chronic infections, posing a major global threat due to its remarkable metabolic versatility, intrinsic and acquired antimicrobial resistance, biofilm-forming capacity, and ability to adapt to diverse environmental and host-associated niches. Continued advances in experimental and analytical methodologies are essential for understanding its complex biology, pathogenicity, persistence, evolution, and interactions with hosts, microbial communities, and the environment.

Despite substantial progress, P. aeruginosa research remains challenged by strain heterogeneity, multidrug resistance, complex regulatory and metabolic networks, biofilm-associated phenotypes, polymicrobial interactions, and limitations in translating laboratory findings into clinically relevant applications. Standardized, reproducible, and innovative methodologies are needed to investigate microbial physiology, genetics, virulence, quorum sensing, antimicrobial susceptibility, host-pathogen interactions, environmental persistence, and therapeutic development across in vitro, ex vivo, in vivo, and computational models.

This Collection aims to provide a comprehensive platform for methodologies that advance Pseudomonas aeruginosa research across the full spectrum of basic, translational, clinical, environmental, and applied sciences. The collection welcomes innovative, optimized, and standardized protocols, as well as emerging technological and interdisciplinary approaches that improve the investigation of this pathogen at multiple biological scales and in diverse experimental settings.

By bringing together robust, reproducible, and broadly applicable methods, this collection will serve as a valuable resource for researchers across academia, healthcare, and industry, promoting methodological standardization, enhancing reproducibility, fostering interdisciplinary collaboration, and accelerating scientific discoveries and the development of effective strategies to better understand, monitor, prevent, and treat P. aeruginosa-associated diseases.
