This generously illustrated book, the fourth edition of the highly acclaimed Diagnostic Virology, is a handbook for the recognition and characterization of virus-induced cellular changes seen by light microscopy, as well as virus morphology seen by electron microscopy. The authors cover all aspects of the subject, from specimen collection and laboratory safety to virus isolation and identification and cell culture. This edition includes a new chapter on the human retroviruses, especially relevant since the onset of the AIDS epidemic, and expands the chapters on the arboviruses and hepatitis viruses.
