Lysed areas suggestive of phage activity were observed on a plate in the course of isolation of a strain of Chondrococcus columnaris from trout at the Fisheries Center of the University of Washington. C. columnaris is an aquatic fruiting myxobacterium responsible for epizootics in salmonid and other fishes (Ordal and Rucker, 1944). Subsequently a(More)
Polynucleotide sequence relationships among 19 strains of marine vibrios, 15 of which were pathogenic to fish, were assessed by analysis of DNA-DNA homo-and hetero-duplexes with the endonuclease S1. DNA base compositions (mole% guanine-cytosine (GC) of selected vibro strains were determined by thermal denaturation. Pathogenic strains from the Pacific(More)
