Which of the following cannot be used to culture viruses?
A
Nutrient agar plates
B
Laboratory animals
C
Embryonated chicken eggs
D
Primary cell cultures
Verified step by step guidance1
Understand that viruses require living host cells to replicate because they lack the cellular machinery for independent growth.
Recognize that nutrient agar plates are used to culture bacteria and fungi, which can grow independently on nutrient media, but viruses cannot grow on these plates since they need living cells.
Identify that laboratory animals provide living cells and tissues for viral replication, making them suitable for culturing viruses.
Know that embryonated chicken eggs contain living cells and are commonly used to culture certain viruses, such as influenza virus.
Understand that primary cell cultures consist of living cells derived from tissues and can support viral replication, making them appropriate for virus culture.
