Notes"Koch's lymph," later called tuberculin, was a bacterial extract. It soon proved ineffective as a treatment, but of great importance in diagnosis and in developing the concept of bacterial allergy (which Koch published in the following year). There is evidence that Koch succumbed to pressure to make his announcement at this time despite his awarenesss that it lacked adequate scientific support. See also entry on this topic for 1991 Koch.
