Can't lend any advice w/re: h202 -- however thought I would suggest three things that have worked for me when all else (including D-mannose, cranberry, uva ursi, etc. failed.)

Grapefruit Seed Extract (drops) as directed on the bottle. I use the Nutribiotic Brand.

-or-

Oil Of Oregano by NAHS - I used Oreganol P73 drops

-or-

If this doesn't do it for you -- last but not least, LDM-100 -- you can buy it online.

Once you are bacteria free, get yourself on a good probiotic -- very important for rebalancing the urinary tract w/good flora

GOOD LUCK!

As I read it, Klebsiella eats lactose, so that means zero dairy. And it is encapsulated, so I'd try to whip that capsule off with papaya and pineapple enzymes. And I'd change my pH per Dr. Larrian Gillespie's WONDERFUL book, "You Don't Have to Live with Cystitis." Gillespie says no cranberry juice as it is too acid. And no turkey, as turkey's tryptophan encourages "Leaky Cell" which is the thinning of the cell wall (ouch! if that is in the bladder) that oozes buffering minerals that makes the pH more acid. Concentrate on kelp for minerals, and a pinch of baking soda in water if needed.

Klebsiella grows in an an-aerobic--oxygen-free--environment, so silver colloid, a hyperoxidizer, and conservative ozone therapy, and oxygen drops, should help. Get Gillespie's book! She's the best! She's Cher's doctor, the one who brought her back from the dead. Avoid ALL nitrates and nitrite bearing foods, including wine, I guess, as they block the uptake of oxygen to red blood cells.

Oh...I'd whack back any latent Candida in the guts as it will snitch all your pH raising Magnesium. Use Caprylic Acid as it is safe for pregnant women. CAPRYL is one brand name. Blessings!
