Pulmonary bacteria to protect against certain respiratory diseases

Pulmonary bacteria with immune-modulating properties that protect against asthma have been isolated from healthy baby mice.

Asthma is a chronic, incurable, multi-factorial pathology whose incidence is increasing in industrialised countries. No long-lasting curative treatment is currently available for this chronic pathology.

A bacterium with immune-modulating properties from the Enterococcus species has been isolated in the healthy lungs of baby mice. It protects them from growth delay due to asthma that diminishes the Th2 signature present in allergic asthma.

Other pulmonary strains have been isolated and tested for their ability to protect baby mice against asthma. This panel of strains offers good candidates for probiotics.
