Study of a bacteriophage infecting the myxobacterium Chondrococcus columnaris.

چکیده
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 bacteriophage was isolated which infected and lysed this particular strain of C. columnaris. Up to this time bacteriophages have not been reported for members of either the Myxobacteriales or the Spirochaetales, the orders of flexible bacteria characterized by the absence of rigid cell walls. In view of the basic difference in structure of the eubacteria and the myxobacteria, a study was undertaken to compare the properties of the myxophage with those of the well studied eubacterial phages. For this purpose a system for a quantitative assay of myxophages had to be developed.

An electron microscope study of the myxobacterium Chondrococcus columnaris has revealed the following structures in the peripheral layers of the cells: (1) a plasma membrane, (2) a single dense layer (probably the mucopeptide component of the cell wall), (3) peripheral fibrils, (4) an outer membrane, and (5) a material coating the surfaces of the cells which could be stained with the dye ruthen...

In 1922 Davis described an infectious disease which was responsible for heavy mortalities in a number of species of warm water fishes in the Mississippi Valley. Although Davis was unsuccessful in his attempts to cultivate the etiological agent, he reported that large numbers of slender, motile bacteria were characteristically present in the lesions of infected fish. He further noted that when m...
