Serological relatedness of the ribonucleic acid-containing coliphages.

Distribution of ribonucleic acid coliphages in Korea.

To determine the geographical distribution of ribonucleic acid (RNA) coliphages in Korea, we collected sewage samples from domestic drainage in densely populated urban areas in July through August, 1979. Of 132 samples, 74 (56%) contained RNA phages (106 strains). They were classified into groups I, II and III (4:47:55) by serological analysis. Based on previous data for Japan (groups II and II...

Distribution of ribonucleic acid coliphages in animals.

To determine the distribution pattern of ribonucleic acid (RNA) coliphages (classified by serological groups I through IV) in animal sources, we isolated RNA phages from (i) feces samples from domestic animals (cows, pigs, horses, and fowls), some other animals in a zoological garden, and humans, (ii) the gastrointestinal contents of cows and pigs, and (iii) sewage samples from treatment plants...

Practical procedures for the purification of bacterial viruses.

The efficiencies of the various methods used for phage concentration have been compared. The two-phase concentration method (with polyethylene glycol and dextran sulfate) gave maximal recoveries of infectivity for coliphages of the T-even and T-odd series and for ribonucleic acid phages and single-stranded deoxyribonucleic acid phages. Precipitation of phages by acid gave high yields when appli...
