The Immunizing Value Of Commercial Hemorrhagic Septicemia Aggressins, L. Van Es, J. F. Olney
The Immunizing Value Of Commercial Hemorrhagic Septicemia Aggressins, L. Van Es, J. F. Olney
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
In 1924, Gochenour published the results of certain experiments which tended to show that what he regarded as a specific aggressin possessed an immunizing value against hemorrhagic septicemia. The aggressin he prepared, by the use of a highly virulent strain of Bacillus bipolaris, was described as having adequately protected seven bovine yearlings against inoculations with the same organism which, when injected into four yearlings, used as virus controls, proved fatal to them. Soon after, if not simultaneously with, the publication of the Gochenour articles, hemorrhagic septicemia aggressin was placed on the market and apparently has since then been sold …
The Immunizing Value Of Commercial Vaccines And Bacterins Against Hemorrhagic Septicemia, L. Van Es, H. M. Martin
The Immunizing Value Of Commercial Vaccines And Bacterins Against Hemorrhagic Septicemia, L. Van Es, H. M. Martin
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
In the course of certain studies having to do with hemorrhagic septicemia, we were particularly struck with the difficulties which we encountered in the immunization of susceptible laboratory animals (rabbits). This difficulty in no small degree excited our curiosity regarding the immunizing value of the considerable number of "Hemorrhagic Septicemia bacterins and vaccines" which during recent years have become such a prominent article of commerce. In the hope of securing some information relative to the immunizing value of the agents mentioned, we undertook a series of experiments in which the immunity of the bacterin and vaccine injected laboratory animals was …
