An aerobiological model of aerosol survival of different strains of Pseudomonas aeruginosa isolated from people with cystic fibrosis

Pseudomonas aeruginosa, a major cystic fibrosis (CF) pathogen, is not thought to be spread by the airborne route. However, previous work (BMC Microbiology 2008, 8:105) showed that airborne transmission of P. aeruginosa is possible. The present study builds on this earlier work and is the most rigorous investigation of the subject undertaken to date. It confirms that airborne cross-infection is likely to occur in CF treatment rooms. As such, it has been influential in changing CF treatment/management policy (Cohen-Cymberknoh et al American Journal of Respiratory Critical Care Medicine 2011, 183:1463–1471). Beggs developed the engineering models used in the study.
