    1. It may be less than bacterium in the immuno-compromised individual. From cases contracted through raw or supposedly pasteurized milk, one may safely assume that, in susceptible persons, fewer than 1, total organisms may cause disease.

    2. The net effect of internalin binding is to exploit the junction-forming apparatus of the host into internalizing the bacterium.
