Effect of long-term voluntary exercise wheel running on susceptibility to bacterial pulmonary infections in a mouse model.

Regular moderate exercise has been suggested to exert anti-inflammatory effects and improve immune effector functions, resulting in reduced disease incidence and viral infection susceptibility. Whether regular exercise also affects bacterial infection susceptibility is unknown. The aim of this study was to investigate whether regular voluntary exercise wheel running prior to a pulmonary infection with bacteria (P.

Respiratory syncytial virus infection facilitates acute colonization of Pseudomonas aeruginosa in mice.

Pseudomonas aeruginosa causes opportunistic infections in immunocompromised individuals and patients ventilated mechanically and is the major pathogen in patients with cystic fibrosis, in which it causes chronic infections. Epidemiological, in vitro and animal data suggest a role for respiratory virus infections in facilitating colonization and infection with P. aeruginosa.
