Abstract:
Pulmonary infections continue to be a significant source of morbidity and mortality among patients with cystic fibrosis. Although our understanding of the pathogenesis and clinical consequences of pulmonary infections with Pseudomonas aeruginosa has increased greatly in recent years, very little is known about potentially emerging pathogens such as Burkholderia cepacia complex, Stenotrophomonas maltophilia, Alcaligenes xylosoxidans, and methicillin-resistant Staphylococcus aureus. In this review, the authors discuss methods for appropriate identification of these "unusual" organisms and their epidemiologic and clinical features. Multicenter surveillance studies are needed to more clearly establish the pathogenicity of these organisms.
Insights
Emerging pathogens like Burkholderia cepacia complex and methicillin-resistant Staphylococcus aureus pose risks to cystic fibrosis patients. This review covers their identification, epidemiology, and clinical impact, highlighting the need for further research.
Area of Science:
- Pulmonary Medicine
- Infectious Diseases
- Microbiology
Background:
- Pulmonary infections are a major cause of illness and death in cystic fibrosis (CF) patients.
- Pseudomonas aeruginosa is well-studied, but less is known about other emerging pathogens.
- Unusual bacterial and fungal pathogens can complicate CF lung disease management.
Purpose of the Study:
- To review the identification, epidemiology, and clinical features of emerging pathogens in cystic fibrosis.
- To highlight the significance of organisms beyond Pseudomonas aeruginosa.
- To emphasize the need for further research into these less common infections.
Main Methods:
- Literature review of current research on emerging pathogens in CF.
- Discussion of diagnostic methods for identifying unusual organisms.
- Analysis of epidemiological and clinical data from surveillance studies.
Main Results:
- Several organisms, including Burkholderia cepacia complex, Stenotrophomonas maltophilia, Alcaligenes xylosoxidans, and MRSA, are emerging threats.
- Effective identification methods are crucial for managing these infections.
- Limited data exists on the precise pathogenicity and prevalence of these unusual pathogens.
Conclusions:
- Accurate identification and understanding of emerging pathogens are vital for CF patient care.
- Multicenter surveillance studies are essential to establish the pathogenicity of these organisms.
- Further research is needed to guide treatment strategies for infections caused by these unusual pathogens.

CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation, but...
