FIG. 1.
Effects of germicides on spores deposited on silicone
rubber medical tubing. Spores were loaded onto tubing, dried, and
exposed for the times prescribed on the products' labels either for
sterilization or for disinfection (indicated on the X axis).
Viable spores were measured in fractions a, b, and c as described in
the text. Bar height represents mean survival, and the bracket over the
bars indicates the SE of triplicate determinations in three to eight
independent experiments.
