OVERLAP OF PHOTOREACTIVATION AND LIQUID HOLDING RECOVERY IN ESCHERICHIA COLI B.

It is known that cells of Escherichia coli B exposed to 2537-A ultraviolet radiation will show a higher survival (photoreactivation) if subsequently irradiated at 3650 A and that they will also show a higher survival (liquid holding recovery) if subsequently held in a liquid. We find that cells given an optimal recovery treatment of one type show no further recovery if also subjected to the other type of treatment. It is concluded that liquid holding treatment acts only upon photoreactivable damage.

ADENOVIRUS-LIKE PARTICLES FROM CANCERS INDUCED BY ADENOVIRUS-12 BUT FREE OF INFECTIOUS VIRUS.

Particles resembling adenovirus were recovered from tumors induced by adenovirus-12. The particles were similar to incomplete adenovirus in size, subunit morphology, and density. The presence of such incomplete viral units helps to explain why attempts to isolate infectious virus from adenovirus-induced tumors have failed despite the serological evidence that viral elements are present.
