You didn't say it was turned off. You said sulfa drug resistance had “disappeared”.

But I expect someone who doesn't know what they are talking about to keep changing their story.

So when you treat an infection with antibiotics that kill 99.99% of the population; why didn't those bacteria turn “on” their antibiotic resistance?

The truth of the matter is that antibiotic resistance is associated with different alleles or the presence of absence of these resistance genes on a plasmid.

The ones that die, die because they lack the proper plasmid or genetic allele. Among the surviving population you find the “correct” plasmid or allele, and it passes on to 100% of the next generation.

Either you’re playing stupid to disrupt the thread, or you really are stupid, which is it?
