The Myxomycetes, because of their naked, mobile mass of protoplasm have served biologists and chemists as material for the study of the characteristics of protoplasm. The typical life his tory of such an organism may be summarized as follows: The vegetative phase in the life history consists of a naked mass of protoplasm, to which Oienkowski (9) applied the name "plasmodium". This plasmodium creeps by reversible streaming over and throughout the substratum, deriving its food from various constituents of decaying vegetable matter which serve as its normal substrate. Upon reaching a state of maturity and under certain environmental conditions, the …

The importance of bacteria as a cause of serious intestinal diseases in man and. other animals has been recognized since the early days of the science of bacteriology. Of those forms usually associated with intestinal disturbances in man, the species considered most important are those belonging in the Salmonella group, the Paracolon group, and the Shigella group. Also, it has been known since the early part of this century that the conman rat serves as an important vector for the dissemination of infectious organisms. For example, standard textbooks list rats as primary vectors of enteric bacteria. However. there has been …
