Pseudomonas aeruginosa and Burkholderia cepacia cannot be detected by PCR in the breath condensate of patients with cystic fibrosis.

The collection of sputum for microbiological examination in young cystic fibrosis patients can be very difficult. However, a knowledge of bacterial flora colonizing the patient's airways is of paramount importance for proper antimicrobial therapy. It is also known that cystic fibrosis patients colonized by Pseudomonas species have a poorer prognosis than Pseudomonas-negative patients.

Capofungin therapy for Aspergillus lung infection in a boy with chronic granulomatous disease.

Neutrophils of patients with chronic granulomatous disease (CGD) are profoundly defective in killing microorganisms. As in patients with chemotherapy-induced neutropenia, CGD patients are highly susceptible to life-threatening invasive Aspergillus infections, and conventional antimycotic treatment is not always successful. The new drug, caspofungin, was used to treat Aspergillus lung infection in one child with CGD.
