Distribution of ribonucleic acid coliphages in Korea

Abstract

To determine the geographical distribution of RNA coliphages in Korea, the authors 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 III [3:1]) and Southeast Asia (mostly group III), the distribution pattern of RNA phages in Korea was of an intermediate type between those of Japan and Southeast Asia.
