Deflagellation of motile cells before the addition of phage leads to a complete inhibition of phage propagation for at least 60 min. Among phage-resistant mutants, many non-motile (mot) and non-flagellated (fla) derivatives of R. lupini H13–3 have been selected. Electron microscopic observations indicate that bacteriophage 7-7-1 attaches with its short tail fibres to the conspicuous helical filament of R. lupini flagella. This attachment is reversible; irreversible phage adsorption takes place at the flagellar base. It is postulated that phage 7-7-1 moves along the rotating flagellum towards a final receptor next to the insertion site of the flagellum, where tail contraction and injection of phage nucleic acid occurs., UL https://www.microbiologyresearch.org/content/journal/jgv/10.1099/0022-1317-34-1-9
