Johann Andreas Rosenberger (born 20 May 1847 in Bonnland;died February 1915 in Würzburg)[1] was a German surgeon and university professor.
Early life and education[edit]
Andreas Rosenberger received his medical training at the universities of Würzburg, Tübingen, Vienna, Halle, Berlin and Prague.
In Würzburg he joined the Corps Bavaria in 1869.
Career[edit]
In 1871, Rosenberger was awarded a doctorate at the University of Würzburg. As an assistant doctor he worked with Heinrich von Bamberger and Wenzel von Linhart. Since 1878 he taught surgery in Würzburg.
Rosenberger appeared in Scientific American in the following article:
The Transformation of Bacteria
"The transformation of the innocent bacteria usually found in healthy organisms into the specific forms associated with certain more or less malignant diseases is something quite unexpected and altogether contrary to prevailing theories; yet the experiments lately made by Dr. Rosenberger, at Wuerzburg, strongly indicate that such may sometimes be the case.
Dr. Rosenberger's experiments were begun to determine the cause of death of an animal poisoned with a septicemic virus, which had been heated so as to destroy all the bacteria in it. The prevailing belief is that cooked virus is simply a poison, and that the injection of it into the blood of a healthy animal kills as strychnine does, as a poison, not as an infection. To decide this question septic blood and serum were heated, filtered, evaporated, and then injected. The animals died with all the symptoms and pathological appearances of septicemic, just as if uncooked virus had been used. The only effect of the cooking was to lessen the virulence of the poison, which, however, was redeveloped in the blood of the animals poisoned. To insure the killing of all the micro-organisms in the cooked virus, the virus was exposed to a temperature of 140 C for two hours, and that this temperature was sufficient to sterilize the liquid was proved by the inaction of it (the cooked virus) in culture liquids.
The inference from Dr. Rosenberger's observations is, as pointed out by the Lancet, that the application of a degree of heat which apparently sterilizes effectually a septicemic virus, so far as artificial cultivation of the organism is concerned, does not prevent the virus from producing in the animal body its specific form of septicemic and of septic bacteria. From these facts the startling conclusion is drawn that the bacteria are not primary but secondary elements in the morbid process, and that their development is associated with a chemical or at least unorganized poison; a poison, however, which the bacteria are the means, and the only means, of multiplying in the animal body. Since these septic bacteria are not contained in the cooked virus when it is injected, the question arises: How then do they come to be in the poisoned animal, which was previously without them?
Dr. Rosenberger holds that they arise from the non-specific bacteria already in the organism; in other words, that under certain conditions bacteria may radically change their nature, so that from being harmless they become virulently malignant. This conclusion is in harmony with the results of Buchner's observations, which seemed, though not conclusively, to show that the bacillus of anthrax might be developed from a non-specific fungus found in (h y); and also with the observations of Rossbach in connection with the physiological action of papayotin, a chemical ferment of vegetable origin, which, when injected into the blood of a perfectly healthy animal causes such a multiplication of bacteria as to produce effects comparable with those of a true infection.
If these observations are sustained by further experiments in this direction, the current theories with regard to the origin of certain specific diseases by infection, always and exclusively, will have to be materially modified; and the position maintained by many intelligent physicians is retired places, that specific diseases like typhoid fever, scarlet fever, and the like, do sometimes originate where the theory of infection is untenable, will be abundantly justified"
Scientific American, 18-Mar-1882[2]
In 1897 he was appointed professor of forensic medicine at the University of Würzburg and at the same time appointed regional court doctor. In 1899 he was released from both offices in order to be able to devote himself exclusively to surgery as an associate professor at the University of Würzburg. His studies on the microorganisms of suppuration, published in 1894, were of particular scientific importance.
Rosenberger belonged to the Royal Bavarian Medical Corps as a medical officer à la suite. His last rank was general doctor à la suite.[1]
Awards[edit]
In 1892 Andreas Rosenberger was awarded the title of Bavarian Councilor.
