O knihe

Excerpt from Manual of Serum Diagnosis

Accordingly, if a bouillon culture of toxic bacteria is prepared and then, after several weeks, filtered, it is always possible by means Of animal experiments to demonstrate the poison given Off by these bac teria. On the other hand the filtrate Of a boullion culture Of infectious bacteria when injected into an animal produces no serious consequences. In this case the poison contained in the body of the bacteria is held back by the filter and becomes free only when the bacteria die and the bacterial bodies dis integrate. In the first group a very small amount of filtrate injected into an animal suffices to excite the entire complex Of symptoms Of the corresponding disease; in the second case the material left behind on the filter must be used. Corresponding to these two large classes Of pathic agents, we distinguish toxic immunity and bacterial immunity.
