What would cause low lactobacillus acidophilus levels in urine? Havnt been on antibiotics since july. Could yeast tablets like Azo cause levl to drop?

Stool contamination. Normally there are no lactobacilli in the urine. If there are low levels in a stool sample that could be due to antibiotics. If you are eating 6 servings of organic fresh vegetables and 1 apple a day and eating a little yogurt each day you should have good bacteria in your GI tract. Cystectomy is very unusual at age 13. Dilitation and curettage could introduce stool bacteria into urine.
