WebMar 5, 2024 · Figure 6.3. 1: Membrane filters can be used to remove cells or viruses from a solution. (a) This scanning electron micrograph shows rod-shaped bacterial cells captured on the surface of a membrane filter. Note differences in the comparative size of the membrane pores and bacteria. Viruses will pass through this filter. Total destruction of the host cell monolayer is the most severe type of CPE. To observe this process, cells are seeded on a glass surface and a confluent monolayer of host cell is formed. Then, the viral infection is introduced. All cells in the monolayer shrink rapidly, become dense in a process known as pyknosis, and detach from the glass within three days. This form of CPE is typically seen with enteroviruses.
