Apparently, antibiotic resistant gonorrhea is on the rise (h/t H-G). Writing in The Atlantic, Megan McArdle says "Once chlamydia or gonorrhea develop resistance to the antibiotics we have, there's no guarantee that we'll get new ones that treat them."
That's true, which is why alternative antibiotic treatments should probably be explored. Two off the top of my head: bacteriophage viruses and Kerry Mullis.
Yes, nobel laureate Kerry Mullis of the great skeptical memoir Dancing Naked in the Mind Field.
He's been working on a new method of boosting the immune system to deal with infections and cancer. I'll let him explain himself here and here (TED).
