BelgianPup, there are a few levels of antibiotics past Cipro, that have worse and worse side effects. Until recently, there were no bugs resistant to Vancomycin but there are starting to be now. <img src="/images/graemlins/frown.gif" alt="" /> Part of the reason there's so many drug resistant bugs now is the huge amount of antibiotics fed to livestock every day whether they need it or not. Otherwise the herds get infected because of the bad conditions (crowded etc.) that they live in. I'm not a serious vegetarian but I do cut back on meat consumption partly for this reason.
There is also one really bad thing patients do, which is they stop taking meds when their illness appears to go away. That is, they're prescribed a 10 day antibiotic course, and maybe after the 6th day, 95% of the bugs are dead and so the symptoms clear up, so they stop taking the pills. They are left with the 5% of the bugs that are the most resistant to the antibiotic, so the illness comes back and is harder to cure the next time around. You have to take all 10 days to get that last 5%. When the prescription says take a pill every day until all the pills are gone, do exactly what it says!!!!
