How can it be that a virus affects a monkey but not a human being? isn't something to do with the 
cells properties of the host, and something to do
with another mammal , or insect that can't be infected?

virus are tissue specific or more appopriate it receptor specific so it nothing to do with type of host...

The most likely possibility is that the monkey's receptor binds whatever molecule on the virus surface that gives it entry to the cell, whereas it is unable to bind the human homologous receptor. Therefore it infects monkey cells but cannot affect human cells.

Yes tamay put it vey well and I second her statement ,  viri are receptor specific and they have no ability to replicate without there target receptors , thus incapacitating them in a non viable host .

anonymous · Answer

I think the type of cell receptor is specially assocated to the animal. If an animals has recepotros on its cells then those are specifically, dear  friend, associated with the genome, the specific genes that are on the organisms cells' surface. I just left our that most viruses oncelocked onto the cell need a matching receptor.  Genes code for cell surface protiens, as well as enzymes, and structural protiens of the host organism.

yes most probably virus are specific in their attachment behave. like you can say many carriers are not get pathologically infected but infect the others pathologically. yet another another can be take into consideration is the host response to that virus in sense of immunity.
