title: Restriction endonuclease activities in the legionellae.
abstract: Fifteen legionellae isolates were studied for the presence of restriction endonucleases. At least three different specificities were found in nine of these isolates. One particular activity was present in two groups of isolates isolated from widely separated geographic areas.
