Coloured TEM of T-bacteriophages attacking E.coli
T-bacteriophages on E.coli. Coloured Transmission Electron Micrograph (TEM) of T-bacteriophage viruses attacking a bacterial cell of Escherichia coli. Seven virus particles are seen (blue), each with a head and a tail. Four of these are \sitting\" on the brown bacterial cell and small blue \"tails\" of genetic material (DNA) are seen being injected into the bacterium. T-bacterio- phages are parasites of bacterial cells. The virus attaches itself to the cell's wall and, using it's tail as a syringe, injects it's own DNA into the bacterium. The virus DNA then takes over the bacterial cell, forcing it to produce more viruses. Magnification: x63,000 at 5x7cm size."
