P. aeruginosa: Pseudomonas aeruginosa. #: evidence in favour of combination therapy for P. aeruginosa remains inconclusive. Aminoglycoside therapy is associated with increased toxicity and monotherapy often leads to the development of resistance against that antibiotic. Therefore, combination therapy with a β-lactam plus a fluoroquinolone is advocated.
