What's the difference between bacterial pneumonia and a bacterial infection of the lungs?

Not much: Pneumonia is usually used to refer to an infection in the clusters of breathing sacs in the lung. I suppose you could say a bacerial infection of the entry of the lung (tracheitis) could be defined better that way but I have never used it that way.To me they would seem to mean the same thing.
