Pathogenicity of Species of the Achromobacter Genus in Patients From Reunion Island With Cystic Fibrosis

Sponsor: Centre Hospitalier Universitaire de la Réunion

Summary

The pathogenicity of Achromobacter bacteria is not yet well established, but studies show a decline in respiratory function and an increase in mortality associated with chronic colonisation, making it possible to classify the Achromobacter genus as an emerging pathogen in cystic fibrosis. It is possible that certain species or clones are more virulent or resistant, requiring the adaptation of measures to prevent cross-transmission in the centres concerned. However, until now, the identification of Achromobacter species has involved the use of molecular biology techniques that are not routinely applicable in diagnostic laboratories, limiting studies and the collection of epidemiological data. Recently, a database using MALDI-TOF mass spectrometry has been built for rapid and accurate species identification. In view of the local epidemiology and the current lack of data, it would be necessary and interesting to use this tool to study a cohort of cystic fibrosis patients in Réunion island (North and South sites) to see whether one species has a greater clinical impact than another (pathogenicity), and/or is more responsible for chronic colonisation.
