Accepted Answer

A clear area against a confluent "lawn" of bacteria is called a plaque. Plaques are formed as a result of bacterial cell lysis by bacteriophages or viruses. The clear area is an indication of the destruction of bacterial cells in that region, and this creates a visible plaque on the surface of the bacterial culture.
