for successful viral isolation, titer, and infectivity. Typically, viruses can only infect a limited number of hosts, known as the host range. This is best explained by a "lock and key" mechanism as certain proteins on the viral surface must fit specific receptor sites on the host cell surface. When using ATCC Get price

Virology Specimen Collection Guidelines Laboratory

For virus specimen selection guidelines, refer to Table 4. In general, specimens for virus isolation should be collected within 4 days after onset of illness as virus shedding decreases rapidly after that time. With only a rare exception, virus cultures are not worthwhile for specimens collected more than 7 days after the onset of illness. Get price

Culturing Viruses

Viruses are obligate intracellular parasites that require living cells in order to replicate. Cultured cells, eggs, and laboratory animals may be used for virus isolation. Although embroyonated eggs and laboratory animals are very useful for the isolation of certain viruses, cell cultures are the sole system for virus isolation in most Get price

Introduction to Virology I: Viral Structure and Function

1. Isolation of virus in tissue culture, animals, embryonated eggs. Most diagnostic laboratories only use tissue culture for virus isolation. A specific cytopathic effect or induction of a characteristic function (e.g., hemagglutination) can indicate the growth of viruses in tissue culture. This can be confirmed with Get price

Plant Disease Diagnosis

Isolation and identification of biotic plant disease causal agents. Isolation of fungi usually requires that pieces of infected plant tissue be placed on various nutrient media 11.
