Hi G.,
I couldn't resist doing my own research because I had never heard of your ailment. My first approach to health is always the most natural. Here are some informational links I found.

I strongly disagree with any recommendation for anti-biotics due to the stress and potential long term damage to the kidneys, liver, and bone joints.

However, these pages had some great information on how you may of contracted this disease and how to prevent future episodes.
In addition to the prevention measures offered, I would also recommend adding the daily supplementation of high-quality ionic silver and high quality vitamins that include a high level of B-12. And, of course, chiropractic is proven to strengthen the immune system.

You may also consider reducing chemical load on your body by going chemical-free. Chemicals are introduced into the body through several ways: skin, ingestion, and inhalation.

Become a label reader. Burt's Bees website has fantastic chemical information: www.burtsbees.com. Avoid over-the-counter drugs and premade foods.
Become a perimeter grocery shopper. It is expensive to go all organic, and not really necessary. Just ensure that any grown food that has naturally occurring oils (olive, corn, grains, etc) is organic. So with things like lettuce and apples, just wash well before eating.
