Multidrug-Resistant Pseudomonas aeruginosa Infection in a Child with Cystic Fibrosis

Abstract

ABSTRACTWe describe a pediatric cystic fibrosis patient who developed a pulmonary exacerbation due to two multidrug-resistant (MDR)Pseudomonas aeruginosaisolates. In addition to these MDR organisms, the case was further complicated by β-lactam allergy. Despite the MDR phenotype, both isolates were susceptible to an antimicrobial combination.
