The development of resistance seems marked.
One example among many would be MRSA
(methicillin resistant Staphlococcus aureus),
which shows highly developed reistance
What I do not know is how resistance comes about.
Is it by random mutation, with resistant mutations
Is it a result of feedback, the bacteria in a given case
responding to changes in their environment brought
about by the presence of antibiotics
(I have not read the book Lamarck's Signature)
Or is it occurring by both of these mechanisms?
I apologise if this strays too far from the original post.
