Hey, Bleen:
Sorry about the yoghurt. Perhaps some health food stores there have starter you can culture yourself. Probiotics is a good option, but without the intestinal healing properties of the yoghurt.
I have had great results with peroxide, and recommend it, but the antibiotics I use are things like Cipro and tetracycline. If large colonies of Kp exist outside the tract, that is along the local supportive tissue and even the mesentery, AS will be independent of whatever is inside the intestines. In some cases--certainly my own--more aggressive elimination of the germ is required, and the Herx effect can be daunting, but the ultimate results spectacular. I am fortunate to live near the border, but some antibiotics can be ordered over the internet as "Fishcycline" and Fishzole (Flagyl-metronidazole).
Sure give the peroxide a go first and good luck with it!
John
