Biophysical Characteristics of the Rna-Containing Bacterial Virus R17

Symposium on replication of viral nucleic acids. 3. Replication of mengovirus ribonucleic acid.

“…These polyhedral viruses have a diameter of about 30 m,4 and contain a single molecule of RNA of approximately 106 to 2 x 106 daltons (38,74). The picornaviruses share many features in common with the RNA-containing bacteriophages (26,34,40,55,64,77) and with the polyhedral viruses of plants (17,57). The use of specific inhibitors has led to the conclusion (76) that the replication of many RNA viruses does not require the synthesis of deoxyribonucleic acid (DNA), nor is it mediated by DNA of the host cell (71,72).…”

Comparison of Two Serologically Distinct Ribonucleic Acid Bacteriophages I. Properties of the Viral Particles

“…Since the original discovery of the f2-coliphage by Loeb and Zinder (13), a number of ribonucleic acid (RNA) bacteriophages specific for Escherichia coli have been independently isolated and studied. These include Alvin J. Clark's MS-2 (21), R-17 (6,7,18), M-12 (10), fr (15), and 3 (17). Recently, Bishop and Bradley (3) isolated six ribonucleic acid (RNA) coliphages which fell into two groups serologically.…”

Comparison of coliphage and bacterial aerosols at a wastewater spray irrigation site

“…Coliphage f2. Bacteriophage f2 was prepared in quantity in TYE broth at 35°C in a batch fermentor with Escherichia coli K-13 as the host strain by the method of Loeb and Zinder (16) as modified by Enger et al (12). For enumeration of coliphage in liquid samples, including those from the LEAP sampler, routine soft agar plaque assay methods were used, with incubation at 35°C.…”
