A virulence-associated filamentous bacteriophage of Neisseria meningitidis increases host-cell colonisation

Fig 8

Proposed model for the role of MDAΦ bacteriophage in the commensal lifecycle of Nm.

Type IV pili are represented in red and bacteriophage in green. After the initial adhesion mediated by type IV pili, bacteria multiply and loose piliation. On the other hand, bacteria in direct contact with the host cells remained piliated. Phage production is activated in the upper layers of the biomass and bacteriophages, which remain in part attached to the bacterial surface, form bundles which stabilize bacteria/bacteria interactions.
