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. WebInclusion bodies are abnormal structures with distinct sizes and shapes and are usually observed in nerve, epithelial, or endothelial cells. They have a characteristic staining property and are typically composed of proteins. …

WebVirus accumulates within the inclusions but nucleocapsids do not. ‘Type-1 cytopathic vacuoles’ (Grimley, Berezesky & Friedman, 1968) are not found. Between 40 and 60 h after infection, the cell-associated virus titre falls by 1 log unit. Cytoplasmic inclusions lose electron-dense material and are transformed into microvesiculated vacuoles. WebLike vacuoles formed during SV40 infection, HRas-induced vacuole formation in glioblastoma cells was independent of ERK signaling and blocked by chemical inhibition of Rac1 .
