Serum treatment of pneumonia. Lechner (Klin. Woch., 1928, No. 28)

In recent years, especially in America, there have been many attempts to treat pneumonia with a specific serum formulated for the four types of pneumococcus found. Such experiments, by the way, were performed by Lechner with a type I serum from the Hoechst's factory, as well as with a polyvalent one. In patients the type of pneumococcus was determined by examining a piece of sputum for 6-8 hours with intra-abdominal culture in a pig.
