THE Friendly Lactobacilli not only colonize your intestinal tract but grow well in your vaginal and urethra, where they prevent growth of pathogenic bacteria. The application of vaginal spermicides (for birth control) like honoxynol-9, found in many contraceptive creams, may kill the friendly Lactobacilli and give pathogens more ready access to your urinary tract.
Taking Lactobacilli by mouth or inserting Lactobacillus capsules into your vagina may restore genital tract symbiosis and prevent infection.
If you do need, after exhausting all known natural methods, to take antibiotics for bladder infection, remember that a 3-day course of treatment usually works as well as a ten-day course. This is not the same as completing only three days of a ten-day course, which can promote the growth of resistant bacteria. Avoid over treatment.
