Main outcome of study (acc. to author)

A frequency dependend statistically significant induction of plaque forming ability was observed. The use of controlled temperature conditions and capable mutants suggest that the effects of the electromagnetic radiation were of a nonthermal nature. Possible changes of conformation on DNA and/or protein-level are assumed.
