title: Heterologous transfection with bacteriophage phiX174 DNA. Unusual heterogeneous products.
abstract: Hydroxylamine-resistant infectious materials (HARIM) synthesized in natural non-host and progeny phage low productive bacterial spheroplasts upon transfection with bacteriophage phiX174 DNA were found to be unusually heterogeneous in their forms. Using Pseudomonas aeruginosa as a source of HARIM, it was shown that they have the following unusual features. (1) Almost all of the HARIM are denser than normal single-stranded (SS)- and double-stranded replicative form (RF)-DNAs of phiX174 found usually in the phage-infected host cells. (2) A great part of these heavy HARIM (approximately 84%) contain a variable length of single-stranded RNA associated with their infectious elements. (3) For most of the HARIM (approximately 80% of total molecules as the infectious elements of the heavy HARIM), the infectious elements are phiX-RFI-DNA. The wide-spread system for phiX-HARIM synthesis was shown to be present in many gram-negative bacterial cells.
