Transmission electron micrograph of Dickeya spp. bacteriophage ϕD3 stained with uranyl acetate. Bacteriophage particle was purified four times by passaging individual plaques using the soft top agar method and D. solani IPO2222 as a host. Phage suspension of ca. 10⁵ plaque forming units (pfu) ml⁻¹ in 1/4 Ringer’s buffer was used for microscopy. At least 10 different photographs were taken. The micrograph presents typical ϕD3 phage particle. Bar marker represents 100 nm [5]
