Excerpt from Focal Infection: The Lane Medical Lectures The importance of the etiologic relation of Focal Infection to Systemic Diseases has been a subject of study in the clinical material of Rush Medical College, in affiliation with the University of Chicago and the Presbyterian Hospital for the past twelve or more years. As the study progressed, the attention and cooperation of clinicians and laboratory workers were aroused and developed into a scheme of "team work." This esprit de corps eventually embraced the nursing staff and the patients. Real clinical research was made possible by this cooperative spirit. Living morbid tissues were obtained at surgical operations and also from other patients, who submitted voluntarily and in many instances requested the removal, when necessary under local or general gas anesthesia, of bits of infected tissue (muscle, capsule of joints, lymph nodes, erythematous nodes, fibrous nodes of tendons) of exudates and of the blood, for experimental purposes. Histologic and bacteriologic studies of this material were made. Animal inoculation was carried on and the lesions of the experimental animals were studied and compared with the morbid human tissues which were the source of the investigation. Eventually the Memorial Institute for Infectious Diseases, the Otho S. A. Sprague Memorial Institute and the Pathological and Research Department of St. Luke's Free Hospital of Chicago cooperated in the work.
