To determine the incidence of brucella abortus and certain other organisms in tonsils

The primary object of the investigation recorded in this thesis was to determine, if possible, the frequency in which the Bacillus abortus of Bang could be recovered from tonsil tissue. It is obvious that normal tonsils would not be available for this study and, therefore, one was compelled to use organs which had been removed for one reason or another - "enlarged tonsils ". From the stand point of the investigation, however, these might be regarded as normal tonsils in this sense that none of the patients from whom they were derived showed any evidence of Undulant Fever, whose causal agent - the Bacillus abortus - was specifically sought. While it has been reported by several American observers (Mohler and Traum,)913., Poelma and Dickens, 1932, and Carpenter and Boak, 1932)that B. abortus can sometimes be isolated from tonsils, we are not aware of any similar investigation having been carried out in this country. It might be argued that this study was of purely academic interest, but in a statistic of 850 samples of fresh milk in the City of Dundee no less than 18% were found to be infected with the B. abortus, (Morton, 1933). It might well be then that the matter is not without practical significance.
