Liệu pháp vi khuẩn đường uống sử dụng các chủng vi khuẩn lactic đường ruột như Lactobacillus và Bifidobacteria giúp tạo được các chất có lợi và khôi phục sự cân bằng hệ vi khuẩn ở ruột. Chúng làm giảm táo bón và các bệnh khác của tuổi già do ức chế quá trình lên men thối ở ruột; phòng và trị tiêu chảy do kháng sinh, kích thích hệ thống miễn dịch hay làm tăng sức đề kháng với bệnh nhiễm.

The effectiveness ratings for LACTOBACILLUS are as follows:
Likely effective for...
- Diarrhea in children caused by a certain virus (rotavirus). Children with rotaviral diarrhea who are being treated with lactobacillus seem to get over their diarrhea about a half day earlier than they would without this treatment. Larger doses of lactobacillus are more effective than smaller ones. At least 10 billion colony-forming units during the first 48 hours should be used.
Possibly effective for...
- Preventing diarrhea in children caused by antibiotics. Giving children Lactobacillus GG (Culturelle) along with antibiotics seems to reduce the diarrhea that children sometimes experience when taking antibiotics alone.
- Preventing diarrhea in hospitalized adults. Drinking a specific beverage containing Lactobacillus casei, Lactobacillus bulgaricus, and Streptococcus thermophilus (Actimel, Danone) twice daily during antibiotic treatment and for a week afterwards significantly decreases the risk of developing diarrhea.
- Preventing diarrhea due to traveling. Traveler’s diarrhea is caused by bacteria, viruses, or parasites that the traveler has not been exposed to before. Taking a specific strain of Lactobacillus rhamnosus, Lactobacillus GG (Culturelle) seems to help prevent diarrhea in travelers. The effectiveness of Lactobacillus GG can vary a lot depending on the travel destination because of differences in bacteria in different locations.
- Preventing diarrhea due to cancer treatment (chemotherapy). A chemotherapy drug called 5-fluorouracil can cause severe diarrhea and other gastrointestinal (GI) side effects. There is some evidence that patients with cancer of the colon or rectum have less severe diarrhea, less stomach discomfort, shorter hospital care, and require fewer chemotherapy dose reductions due to GI side effects when they take a particular strain of Lactobacillus rhamnosus, Lactobacillus GG (Culturelle).
- Colic in babies. Taking a specific Lactobacillus reuteri product (Probiotic Drops, BioGaia AB) 100 million CFUs once daily for 21-28 days reduces daily crying time in nursing infants. Taking this Lactobacillus reuteri product seems to be more effective than using the drug simethicone.
- Lung infections. Children ages 1 to 6 years who attend daycare centers seem to get fewer and less severe lung infections when given milk containing lactobacillus GG or a specific combination product containing both Lactobacillus acidophilus and Bifidobacterium (HOWARU Protect).
- Treating a bowel condition called ulcerative colitis. Some research suggests that taking a specific combination product containing lactobacillus, bifidobacteria, and streptococcus might improve symptoms. Taking lactobacillus also seems to help treat chronic pouchitis, a complication of surgery for ulcerative colitis. Continuous treatment for one year with a specific concentrated formulation of lactobacillus, bifidobacterium, and streptococcus (VSL#3) seems to help most patients.
- Treating irritable bowel syndrome (IBS). There is some research showing that certain strains of lactobacillus, but not others, can improve symptoms of IBS such as bloating, and stomach pain.
- Treating vaginal infections caused by bacteria (bacterial vaginosis). Clinical research shows certain strains of Lactobacillus might help treat bacterial vaginosis when applied inside the vagina. Researchers have found Lactobacillus acidophilus suppositories (Vivag, Pharma Vinci A/S, Denmark) and vaginal tablets (Gynoflor, Medinova, Switzerland) may be effective. Researchers also found that vaginal capsules Lactobacillus gasseri and Lactobacillus rhamnosus, seem to lengthen the time between infections.
- Treating and preventing eczema (atopic dermatitis) in infants and children who are allergic to cow’s milk. A combination of freeze-dried Lactobacillus rhamnosus and Lactobacillus reuteri seems to reduce eczema symptoms in children ages 1 to 13 years.
- Helping prescription medications treat Helicobacter pylori (H pylori) infection, which causes stomach ulcers.
- Treating diarrhea caused by the bacterium Clostridium difficile.
Possibly ineffective for...
- Vaginal yeast infections after taking antibiotics. There is evidence that taking lactobacillus by mouth or eating yogurt enriched with lactobacillus doesn’t prevent vaginal yeast infections after antibiotics. However, women with yeast infections who use vaginal suppositories containing 1 billion live Lactobacillus GG bacteria twice daily for 7 days in combination with conventional treatment often report their symptoms improve.
- Crohn's disease.
- Lactose intolerance.
- Reducing symptoms of too much bacteria in the intestines.
Insufficient evidence to rate effectiveness for...
- Urinary tract infections (UTIs). There is some preliminary evidence that vaginal use of some Lactobacillus species might be helpful for preventing UTIs, but not all studies have agreed.
- General digestion problems.
- Necrotizing enterocolitis (NEC) in babies born prematurely.
- High cholesterol.
- Sensitivity to milk (lactose-intolerance).
- Lyme disease.
- Hives.
- Fever blisters.
- Canker sores.
- Acne.
- Cancer.
- Boosting the immune system.
- Common cold.
- Preventing infections in people on ventilators.
- Other conditions.
Many bacteria and other organisms live in our bodies normally. "Friendly" bacteria such as lactobacillus can help us break down food, absorb nutrients, and fight off "unfriendly" organisms that might cause diseases such as diarrhea.
