The bronchopneumonia from CAR bacillus infection is similar to that of mycoplasmosis. The right middle lobe appears to be the most commonly affected site.
Peribronchiolar lymphoid hyperplasia with transmucosal lymphocyte migration as in mycoplasmosis is suggestive of CAR bacillus. Silver stains and immunofluorescent techniques will demonstrate the organism (arrow) in tissues.
