We attribute this to the sanitary system of the submarine, but were unable directly to recover high concentrations or organisms during its operation. Nevertheless, if the low levels of staphylococci, coliforms and enterococci recovered from the air can be considered representative of continuing air contamination, one may calculate that, in the course of a patrol, crew members inhale at least 900 staphylococci and coliforms, and 18,000 enterococci; periodically in Patrols II and III dosages were 1000-fold greater.
