Comprising over 100 chapters, organised into 17 major sections, the scope of this impressive work is wide-ranging. The gram-negative bacterial pathogen Pseudomonas aeruginosa represents a prominent clinical concern. Pseudomonas aeruginosa is a gram-negative, rod-shaped, asporogenous, and monoflagellated bacterium that has an incredible nutritional versatility. 1-3 These pulmonary infections are thought to be initiated by the attachment to and subsequent colonization of the mucosal epithelium of the upper respiratory tract by P. aeruginosa and followed by a descending infection mechanism.
