A bacterium that naturally lives in the human gastrointestinal tract. Lactobacillus GG (LGG) is a bacterium that naturally lives in the human gastrointestinal tract.
Lactobacillus GG (LGG) is a bacterium that naturally lives in the human gastrointestinal tract. LGG was named after its co-discoverers, Gorbach and Goldin. The scientific name for LGG is Lactobacillus rhamnosus. LGG is a probiotic.  Lactobacillus rhamnosus GG, also known as  L. rhamnosus GG or LGG is a probiotic bacteria with many health benefits. As you learned on the Lactobacillus rhamnosus general page, this species of bacteria has some unique characteristics depending on the strain. In the patent application, it was claimed that Lactobacillus rhamnosus GG can survive in normal human stomach acid at pH of 2.5 for 30 minutes and is bile stable. This means that it can survive passage through the stomach and small intestine. Lactobacillus GG (LGG) has shown promising results in treating diarrhea caused by viruses and bacteria in both adults and children. Measurements of intestinal microflora show that LGG adheres to the intestinal wall during healthy periods as well as during episodes of diarrhea. Lactobacillus GG not only lowered levels of glycosylated hemoglobin, it also improved glucose tolerance in the animals. Probiotics such as Lactobacillus GG, Bifidobacterium, and Lactobacillus acidophilus significantly reduce the amount of pathogenic bacteria that inhabit the nasal passages, according to a recent study. Not all types of bacteria are bad for you. In fact, your body needs a certain amount of bacteria to function properly. Lactobacillus acidophilus is a form of bacteria that’s found naturally in the body, usually in the intestines, mouth, or female genitals. It’s considered beneficial to human health because the bacteria doesn’t cause disease.  Strain Specificity. Not all probiotics offer the same effects. The health benefits of probiotics are strain specific, meaning that different types of probiotic microbes affect your body differently. Lactobacillus rhamnosus GG is a specific bacterial strain. Lactobacillus is the name of the genus to which it belongs. Rhamnosus is the name of the species. GG denotes the strain. Even something so slight as a different letter or two in the spelling of its name can mean that your probiotic is a different strain and may not have the same effects.  Lactobacillus rhamnosus is a bacterium that originally was considered to be a subspecies of L. casei, but later genetic research found it to be a species of its own. It is a short Gram-positive facultative anaerobic rod that often appears in chains. While Lactobacillus rhamnosus GG (ATCC 53103) is able to survive the acid and bile of the stomach and intestine, is claimed to colonize the digestive tract, and to balance intestinal microflora, evidence suggests that Lactobacillus rhamnosus is likely a transient inhabitant, and not autochthonous. Perhaps you have seen the word Lactobacillus Gg on the back of a probiotic or other nutritional supplement. Lactobacillus Gg is actually only one strain of particular healthy or beneficial bacteria, also known as (flora). This flora bacterium helps to stop the growth of harmful toxic bacteria in the digestive tract.  Lactobacillus rhamnosus GG (ATCC 53103) is a strain of L. rhamnosus that was isolated in 1983 from the intestinal tract of a healthy human being; filed for patent on 17 April 1985, by Sherwood Gorbach and Barry Goldin, and the 'GG' derives from the first letters of their surnames. While Lactobacillus rhamnosus GG (ATCC 53103) is able to survive the acid and bile of the stomach and intestine, is claimed to colonize the digestive tract, and to balance intestinal microflora, evidence suggests that Lactobacillus rhamnosus is likely a transient inhabitant, and not autochthonous. Overview. Lactobacillus acidophilus (L. acidophilus) is the most commonly used probiotic, or good bacteria. Many healthy bacteria live in the intestines and vagina where they protect against the bad bacteria that cause disease. They do this in a couple of ways.
