Transmission of Pseudomonas aeruginosa epidemic strain from a patient with cystic fibrosis to a pet cat

Thorax. 2008 Sep;63(9):839-40. doi: 10.1136/thx.2007.092486.


Chronic infection with Pseudomonas aeruginosa is common in cystic fibrosis (CF) and certain strains are more transmissible and virulent than others. Of these, the Liverpool Epidemic Strain (LES) is highly transmissible and cross infection has been reported between patients with CF and healthy non-CF relatives. However, the risk of transmission from humans to animals is unknown. The first report of interspecies transmission of the LES strain of P aeruginosa from an adult patient with CF to a pet cat is described. This development further complicates the issue of infection control policies required to prevent the spread of this organism.
