Fig 2.

Morphological groups of temperate phages and phage-tail-like particles (PTLPs). Micrographs show representatives of the five main types of particle morphology observed: medium myoviruses (MMs), long-tailed myoviruses (LTMs), small myoviruses (SMVs), siphoviruses (SVs), and PTLPs. Assignation of the myovirus particles was made according to the capsid diameter and tail length; MMs had capsid diameters of 60 to 70 nm and contractile tail lengths of approximately ∼130 nm, LTMs had capsid diameters of 60 to 70 nm with tail lengths of 150 to 220 nm, and SMVs had capsid diameters of 40 to 50 nm and tail lengths of ∼105 nm. Bars represent 100 nm.
