TEM of T2 Bacteriophage viruses attacking bacterial cells of Escherichia coli.
In the three color-enhanced Transmission Electron Micrograph images, it can be seen virus particles, each with a head and a tail "sitting" on bacterial cells of E.coli. In which genetic material is injected into the bacterium.
As known, bacteriophages can be said to be the parasites of bacterial cells. The virus normally attaches itself to the cell's wall and, using its tail as a syringe, injects its own DNA into the bacterium. The virus DNA then takes over the bacterial cell, forcing it to produce more viruses(orange) as seen in the first image inside the bacterial cell(green).
