Introduction to Virology: Structure & Classification

Virus

An obligate intracellular parasite requiring living cells for replication, often causing observable effects such as cell death. They are studied in virology.

Capsid

A protective protein coat enclosing the viral genetic material.

Organoids

Miniaturized organ models created in vitro to study infection and treatment.

Cell Culture

A laboratory technique to grow cells under controlled conditions for research, crucial in producing vaccines.

Viral Titer

A measure of the concentration of infectious viral particles in a sample, often quantified using serial dilution.

Permissive Cells

Cells that allow viruses to enter and replicate.

Vaccines

Biological preparations that provide immunity against viruses, often produced in chicken eggs and studied through cell culture.
