Summary Bacteriophages for three strains of A. tumefaciens were concentrated by ultracentrifugation, stained with 1% phosphotungstic acid (PTA), or 0.5% uranyl acetate, and examined with the electron microscope. Phage PT11 was a bacillary-shaped particle with a whip-like tail containing a knob at its distal end. Phage PIIBNV6 appeared to have an icosahedral head. The wide non-contractile tail terminated in a plate with pegs. Phage PIIBNV6-C was an icosahedral particle with a short, spike-like tail. Host cells of A. tumefaciens were encapsulated rods bearing polar or lateral flagella.
