Cytopathic effect or cytopathogenic effect (abbreviated CPE) refers to structural changes in host cells that are caused by viral invasion. The infecting virus causes lysis of the host cell or when the cell dies without lysis due to an inability to replicate. Both of these effects occur due to CPEs. If a virus causes these morphological changes in the host cell, it is said to be cytopathogenic. Common examples of CPE include rounding of the infected cell, fusion with adjacent cells to form WebCytopathology Characteristic cytopathic effects occur in infected cells. Specimens from vesicular skin and mucosal lesions may be obtained by scraping the edge of the ‘unroofed’ lesion with a sterile swab or scalpel blade, smearing onto a slide and fixing the cells with 95% ethanol, Zenker's solution, or Bouin's solution (Tzanck smear).
