Summary: Specialized transduction by phage 16-3 of one of the markers of is described. The frequency of transduction was 10 to 10 per plaque-forming unit. About two-thirds of the transductants were heterogenotes, unstable for the marker, and yielded high frequency transducing lysates (10 per plaque-forming unit). In phage lysates, plaque-forming transducing particles were directly demonstrated while non-plaque-forming particles were only detected indirectly via complementation of defective lysogenic transductants. In the defective transductants, the two distal ends of the vegetative phage map were lacking. By plasmid transfer, the attachment site of phage 16-3 was located close to the and markers. Transduction of the marker could not be demonstrated.
