Etiology of the infectious process in pulmonary and mixed forms of mucoviscidosis in children

: The specific features of an infectious process were studied in 150 children treated for mucoviscidosis at the State Pulmonology Research Center, Ministry of Health and Medical Industry of the Russian Federation. Hemophilic bacilli, Staphylococcus aureus, and Pseudomonas aeruginosa were fond to play the leading role in the etiology of the infectious process in the bronchopulmonary system. Pneumococcal infection was first ascertained to be important in the course of the disease. Developmental stages of a pyoinfectious process from the onset of its contamination, acute infection to chronic one were followed up. The most severe, prognostically unfavourable course of the disease was demonstrated to be associated with Pseudomonas aeruginosa infection.
