A Good Diagram of How Antibiotic Resistance Evolves

Bacteria can pass resistance to each other via plasmids right?

Steven,

yes, but the rate of plasmid transfer is usually very low, so, in effect, it should be thought of as a funky kind of mutation. In other words, plasmid transfer isn't infectious, in the way that a virus is.

As with all things in biology, there are obviously exceptions.

There are chemical signals that increase the rate of plasmid transfer. I don't know if antibiotics have this kind of effect, but I wouldn't be surprised if some do.

(I used to work on this - except the transfer was from bacteria to plants.)

thanks

I recall reading an article that said the opening shots in the next world war would be in cyberspace, with dodgy spambots flooding the net.

Either that or its viral marketing.

thanks for all

One of the confusing things about the evolution of resistance (and natural selection, for that matter) is the notion that the evolution of resistance happens among individuals within populations. This graphic from the Washington Post lays that out quite nicely:
