Final answer:
The measles virus can infect multiple cell types, whereas the poliovirus has more restricted tissue tropism, with receptors found mainly in the gastrointestinal tract and possibly the central nervous system.
Step-by-step explanation:
Measles virus receptors, known as CD46 receptors, are found on most nucleated human cells. This includes immune cells, epithelial cells, and endothelial cells. Therefore, they are present in most tissues. On the other hand, poliovirus receptors, known as CD155 receptors, are mainly found in the peripheral neurons and some neuronal cells of the central nervous system.
So, while measles virus receptors are found in most tissues, poliovirus receptors are limited to specific cell types, making the statement False.
The statement that measles virus receptors are present in most tissues is true, as the measles virus can infect multiple cell types, leading to symptoms such as brain and skin infections. In contrast, poliovirus receptors are more restricted in their distribution, as poliovirus initially replicates in the pharynx and gastrointestinal tract before potentially spreading to the central nervous system (CNS), often leading to paralysis. Therefore, the correct answer to the question is True: measles virus receptors are present in most tissues whereas poliovirus receptors are present in only a select few.
