Yikes! Thanks for the link, there's a lot of data there that I'll go over this evening.
I didn't read the link above, and just posting quickly, but wild-type is typically referred to the virus we carry, resistant strains of course are related to the tx.
resistant strains can also be called less-fit, meaning even though they developed, they might not have the potency they should.
