Abstract:
:Seventeen bacteriophages, active against 19 Arthrobacter soil isolates, were isolated from concentrated samples of river water and sewage. Attempts to isolate Arthrobacter bacteriophages from filtrates of broth cultures of the soil isolates or from ultraviolet light-irradiated cultures were unsuccessful. Bacteriophages were not detected in either concentrated or unconcentrated soil extracts. Electron microscopic studies of 11 phages showed morphologies characteristic of Bradley's groups B (exhibited by 9 phages) and C (exhibited by 2 phages). Moles percent guanine plus cytosine, calculated from the deoxyribonucleic acid density of three phages, ranged from 60.2 to 65.3. The phages were characterized by their plague and virion morphology, host range, and serological specificity.
