The interaction of bacteria with pulmonary surfactant.

Common organisms that were unable to manufacture or metabolize lecithin caused no alteration in the surface activity or fatty acid pattern of lecithin. A reduction of surface activity by microorganisms of crude pulmonary extract or phospholipid fractions appeared to be due to an inhibition of activity by the less surface-active phospholipid components that bacteria produced.
