(Right:)"A delta bacteriophage. The first was identified in a new study in Frontiers in Microbiology to have binding sites for CtrA. A protein produced by the bacteriophage’s host that regulates the production of pili and flagella. The presence of these binding sites only in phages that require their host cells to have pili/flagella to infect them suggests that the phage is monitoring the presence of this protein to “decide” whether to stay put or replicate and emerge from its host cell.

Could viruses be more active than researchers expected?
Some viruses might be more active than nobody expected. The bacteriophages can even swim to their target cell. So in that case virus will not just wait for the cell it swims to its target. This ability is suitable for bacteriophages that are hunting for bacteria from nature.
There is the possibility that some viruses have a more complicated data-analyzation system than nobody expected. We know that the DNA plasmid of bacteria can operate as the chemical brain. But the new research shows, that also the DNA or RNA of viruses can act similar way, as the DNA plasmid of bacteria.
So also, viruses might have this kind of chemical computer or chemical brain. The chemical brain of viruses could also have some kind of sensors. The proteins that form viruses could act as sensors and at least some viruses can swim to their target.
The reason, why some people believe that especially bacteriophages must swim to their target is that those viruses must find the bacteria that are not resistant to those viruses. If viruses have this swimming ability they could revolutionize medical work. That ability makes it possible to create intelligent medicines that DNA or RNA controls. And this thing can make it possible to create also small but complicated nanomachines.
When we look at the form of bacteriophages. It looks like a tiny space rocket. And the small feet of the virus can also help it to track the cells and swim to the target. The idea is that when a certain molecule hits a certain point of a virus. It activates an electrochemical reaction that moves the feet of the virus. And the form of the virus helps it adjust the direction where it moves.
Then this genius system turns the virus upside down and makes it to "land" over the ion pump of the cell. The ion pump pulls the bottom of the virus to it. And then it simply pulls the genome of the virus to the cell. Or there is a possibility. That there is a cutter enzyme at the front of the DNA or RNA of the virus. When a virus touches the core of its victim it shoots its genome straight through the cell.
