The like phenomena repeat themselves in all those cases where it is possible to follow the fate of the micro-organisms of acute disease during the stage of recovery. Thus rats and pigeons very frequently survive an attack of anthrax, and, where this occurs, the bacteria, which at the commencement of the disease were for the most part free, now, during resolution, are for the most part included within leucocytes and splenic phagocytes. Nor is this all; analogous phenomena as a rule attend immunity, which most often is but recovery in operation from the very onset of a disease. The more closely one studies this condition of immunity, the more is one led to the conviction that immunity and recovery are very intimately connected ; that one can pass by slight gradations from the resolution of disease to the production of immunity. So it is that, in inoculating refractory animals with the microbe to whose action they have been rendered immune, it is found that the parasite begins to develop, but that from the onset a reaction on the part of the organism shows itself, accompanied by a considerable emigration of leucocytes which soon include the bacteria in great ..â c; Fig. 3.âAnthrax of pigeon (an animal but slightly susceptible to the disease), to show stages of destruction of bacilli by phagocytes. 1 and 2, macrophages ; 1, from exudation from eye of refractory bird ; 2, from muscle of region of inoculation of bird that succumbed; 3, 4, 5, microphagesâall from eye twenty-seven hours after inoculation; a, a, unaltered bacilli; 61, b2, bd, bacilli becoming more and more degenerated and indistinct; c c, debris of bacilli (Zeiss 1-18
