I've read about this bacteria in The Yeast Connection and The Woman. Here is some info from the book. "Dr. Barry Marshall a young Australian/American physician found that the bacterium Helicobacter pylori played a major role in gastritis and gastric ulcers. He noted that by taking a prescription of Flagyl, tetracycline and Pepto-Bismol, more than 80% of ulcer patients are cured."
" Dr.Marshalls discovery is exciting. The treatment program he outlined is helping many people. Yet since tetracycline and Flagyl encourage the growth of Candida Albicans in the digestive tract, adding Nystatin and a probiotic to the treatment program is an option worth considering."
