Investigations on complement fixation in hog cholera
Abstract taken from first paragraph of the Introduction section of this thesis: At the present time no biologic test for the diagnosis of hog cholera exists by means of which the presence of the disease in a herd can be determined in the early stages of an outbreak, and before the disease has gained considerable headway. In the beginning of an outbreak, in individual herds, or in a neighbornood, time is frequently lost in awaiting developments that will furnish positive evidence of the presence of hog cholera. The importance therefore of a quick and reliable method to diagnose hog cholera is readily seen. At present the clinical symptoms, gross lesions, and the epizootic character of the disease are the only means by which we can arrive at a diagnosis. And these evidences are sometimes absent. This paper is devoted to the investigation of the possible application of the Complement Fixation Test to the diagnosis of hog cholera.
