This slide is pretty straight forward. Lots
of polys, all in the alveolar spaces. Unlike slide 58, the bug is not causing
the destruction of the pulmonary tissue itself. What's the likely bug in this
case?
Compare this slide with the case
of interstitial pneumonia (slide 172) and the necrotizing pneumonia of slide
58. One is a response to a virus and the other to a very aggressive bacteria.
In this slide, however, we see the infiltrate in the alveolar spaces and
the inflammatory response is that expected against a bacteria (lots of polys).
