American Association of Pathologists and Bacteriologists

The American Association of Pathologists and Bacteriologists (AAPB) was an American national professional association established in 1901, devoted to fundamental science and academic medicine as distinct from clinical medicine. In 1976, they joined with the American Society for Experimental Pathology (ASEP) to form the American Association of Pathologists (AAP), which in 1992 became the American Society for Investigative Pathology (ASIP).

In 1924 the Council voted to end the Journal of Medical Research and with a grant from the General Education Board of the Rockefeller Foundation, the AAPB started the American Journal of Pathology on January 1, 1925, noting on the cover that it was a continuation of the Journal of Medical Research.
