Susceptible cultured cells infected with which of the following viruses would exhibit hemadsorption with the appropriate erythocyte ?
**Core Concept**
The question tests the understanding of viral infections and their effects on cultured cells, specifically the phenomenon of hemadsorption. Hemadsorption is a technique used to detect viruses that cause cells to bind to erythrocytes.
**Why the Correct Answer is Right**
The correct answer is related to viruses that can cause hemadsorption, which is a characteristic feature of certain viral infections. For example, influenza virus and respiratory syncytial virus (RSV) can induce hemadsorption due to the expression of viral hemagglutinin on the surface of infected cells.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because the virus in question does not typically cause hemadsorption.
**Option B:** Similarly, this option is incorrect as it does not lead to hemadsorption in cultured cells.
**Option C:** This option is also incorrect as the virus does not induce hemadsorption.
**Clinical Pearl / High-Yield Fact**
Hemadsorption is an important diagnostic tool for detecting viral infections, particularly those caused by influenza and RSV. It is essential to remember that not all viruses induce hemadsorption, making it a specific and useful technique in virology.
**Correct Answer:** Correct Answer: D. Influenza virus.
