Quick question for you, In light of Bouchard's problem with the streptococcal bacteria, I was wondering about the following theory I've had: If someone has strep throat, they take antibiotics to fight it. Now, in most cases people take the antibiotics through to the end, and kill off the problem. But, some don't finish the drugs, because they think their symptoms are gone. Then, when the disease hits them again, they're surprised and go back to the doctor for another dose. However, they have implemented Darwinian selection nicely, because the more resilient bacteria have made it through the first "wave" of biological warfare that antibiotics waged. This is a reasonably well known concern - antibiotics breeding stronger disease and bacteria. However, even if the people do take the antibiotics through to completion, the stronger bacteria will live in the host the longest, making them more likely to be communicated to other individuals... Now suppose that a strain of bacteria starts in an individual, and undergoes the selection process of scenario one repeatedly, continually being knocked down, then climbing back up... It seems quite reasonable to conceive that this strain will become quite resilient to antiobiotics, and being such a selective population of bacteria, may not resemble the original bacteria from which it was spawned. If you take a large number of people, and remove all people over 6'4, chances are that you will have a group of people that are better at basketball than the 'average' person, statistically. Is this possible with the streptococcal bacteria as well? Perhaps this usually 'peaceful' bacteria can undergo such hyper-accelerated selection that it becomes incredibly strong and resistant to anti-biotics, and at the same time, it's nature changes due to its very specific selection criteria? The question then would be - how come this super-strain doesn't spread all over and nuke us all in a giant plague? Well, it would seem possible to me that as the nature of the bacteria changes, so too would it's means of transmission. If the bacteria prefers to get into your bloodstream and tissue, rather than into your throat and lungs, then transmission of the bacteria becomes more difficult - they lose their airborne advantage, and require transmission via open wounds. Is there any possible truth to any of this, or is it all garbage? I'm completely ignorant in this field, so forgive me for having fun with something I know nothing about. Please CC email to me with any thoughts or criticisms you might have. Steve Franklin
