Learn about the various methods of growing viruses, including using living cells, animals, and embryonated eggs. Discover how to identify viruses through cytopathic effects, serology tests, and nucleic acid studies.
E N D
Growing Viruses 7 • Viruses must be grown in living cells • Bacteriophages form plaques on a lawn of bacteria Figure 13.6
Growing Viruses 8 • Animal viruses may be grown in living animals or in embryonated eggs Figure 13.7
Virus Identification 9 • Cytopathic effects: Detectable changes in the host cell due to viral infection (p. 441) • Blood serum (serology) tests • Detect antibodies against viruses in a patient • Use antibodies to identify viruses in neutralization tests, viral hemagglutination, and Western blot • Nucleic acids: Studies of the DNA/RNA
