Colour enhanced transmission electron micrograph showing sections through absorbed T2 phages attached to intact E. coli B cells or to large wall fragments by both their long and short tail fibres. E. coli B cells were infected with T2 phages; after 1 hour they were fixed and then embedded. Rather thick, silvery gold-coloured sections were cut and subsequently examined in the electron microscope. The long tail fibres extend laterally from the baseplates; they flex near their centers and their distal tips are attached to the cell walls. The long tail fibres attach to the walls at points over 800 A from the intersections of the needles with the walls. The short tail fibres go directly from the baseplates to the walls. | |
