[Bacteriology of mucoviscidosis during a 5-year period]

Abstract

Background: We have studied the bacteriology of mucoviscidosis cases from 1985 to 1989.

Material: A total of 336 samples from 50 patients (median age: 7 year, range: 1 day-18 years) with mucoviscidosis were studied.

Results: The most frequently isolated microorganisms was Pseudomonas aeruginosa (59.2%), followed by Staphylococcus aureus (19%) and Haemophilus influenzae (18.4%). In patients younger than 1 year of age other different microorganisms were identified in 61.1% of cases, but S. aureus (11.1%) and Pseudomonas aeruginosa (5.5%) were also isolated. The incidence of Pseudomonas cepacia (0.6%) is low in our environment. We did not isolate any Legionella sp. strain.
