The visualization of viral particles only became possible after the advent of the electron microscope. The first bacteriophage images were published in 1940 and were soon followed by many other publications that helped to elucidate the structure of the particles and their interaction with the bacterial hosts. As sample preparation improved and new technologies were developed, phage imaging became important approach to morphologically classify these viruses and helped to understand its importance in the biosphere. In this review we discuss the main milestones in phage imaging, how it affected our knowledge on these viruses and recent developments in the field.

“…They correspond to the novel genus “7-11-like viruses” of enterobacterial phages. 12 In summarizing his observations in 1943, H. Ruska reported at least four morphotypes of bacteriophages 13 and proposed a morphological classification of viruses. 14 …”

The first phage electron micrographs were published in 1940 in Germany and proved the particulate nature of bacteriophages. Phages and infected bacteria were first examined raw and unstained. US American scientists introduced shadowing and freeze-drying. Phages appeared to be tailed and morphologically heterogeneous. Phage types identified by early electron microscopy include enterobacteriophages T4, T1, T7, T5, 7–11, ViI and Pseudomonas phage PB1. This paper retraces the development of early virus electron microscopy till the introduction of negative staining.

The morphology of 28 bacteriophages active on members of the ProteusProvidence group of organisms was examined by a negative staining technique. Examples of the 'T-even', T 3 and P22 morphologies were encountered as well as phages with non-contractile cross-striated tails resembling a group of coliphages. Others resemble staphylococcal and pseudomonas phages. Two phages (9, 7479) with octahedral capsids were encountered. A temperate Proteus mirabilis phage (12/57) and a temperate P . morganii phage (10041/2815) differ from phage P 22 in that they possess collars. A P. rettgeri phage (7480 b) is unique in that it possesses a head with a regular hexagonal outline, a collar and a non-contractile tail while a Providence phage (9266) is believed to be the largest phage active on Gram-negative bacteria.
