adaptive
community acquired pneumonia is called by
streptococcus pneumoia

damage
infection
immune response
chronic infections of the lung examples
chronic bronchitis
bronchiectasis
what damage promtoes and exacerbates chronic infection of lung
smoking
what does immune system activation do to chronic lung infection
exacerbate it
