Abstract: Since the discovery of the first virus infecting members of the class Cyanophyta (Safferman and Morris, 1964), a number of cyanophages have been isolated which clearly indicate that cyanophages are widely distributed in bodies of fresh and brackish water. As of yet, most of the phages which have been isolated have filamentous hosts (Safferman and Morris, 1963; Singh and Singh, 1967; Safferman et al. 1969b; Daft et al. 1970; Adolph and Haselkorn, 1971). Only a few cyanophages have been discovered which infect unicellular hosts (Safferman and Morris, 1969; Safferman et al. 1972; Adolph and Haselkorn, 1973; Sherman et al. 1976). The Cyanophyceae, more commonly known as the blue-green algae, occupy a unique biological position. Due to their photoautotrophic nature and possession of the photopigments chlorophyll a and B-carotene, distinctive characteristics of plant photosynthesis, blue-greens are regarded by botanists as a class of algae (Stanier et al. 1971). However, the bacterial nature in both cellular and organismal respects of the blue-green algae has long been recognized by cell biologists (Pringsheim, 1949; Echlin and Morris, 1965; Carr and Craig, 1970). This has led to the increasing usage of the more descriptive term cyanobacteria, or, blue-green bacteria (Buchanan and Gibbons, 1974).
