Lactobacillus rhamnosus, a probiotic with good survival capacity in the human gut, has well-documented adhesion properties and health effects.

Lactobacillus rhamnosus was first isolated in 1983 and is known to have a strong avidity for human intestinal cells and can survive acid and bile environments. It is considered one of the most studied probiotics, with research showing that it could do the following:

- alleviate rotavirus diarrhea in children,

- prevent atopic dermatitis,

- protect against urinary tract infections,

- and improve symptoms of irritable bowel syndrome.

Lactobacillus rhamnosus appears to be safe and effective in prolonging remission in UC patients. LGG has also been studied in CD, but found to be no better than placebo.

Decreased and normal levels of Lactobacillus spp. have been reported in patients with irritable bowel syndrome. Lactobacillus spp. abundance was shown to be lower in the active phase of ulcerative colitis. Lactobacillus levels were shown to be increased after inulin consumption, but decreased after consumption of maltodextrin. Polyphenols derived from chocolate, green tea, blackcurrant, red wine
and grape seed extracts have been shown to increase Lactobacillus species. The increased abundance of Lactobacillus species has been associated with amelioration (=improvement) of inflammation.

Lactobacillus salivarius is a type of probiotic bacteria that plays a significant role in maintaining a healthy gastrointestinal (GI) tract. Lactobacillus salivarius is used to assess the levels of this beneficial bacterium in the digestive system. Lactobacillus salivarius is known for its ability to produce lactic acid, which helps to lower the pH in the gut and creates an environment that is less favorable for harmful bacteria and pathogens. This probiotic also contributes to the overall balance of the gut microbiome, which is crucial for proper digestion, nutrient absorption, and immune function. Additionally, Lactobacillus salivarius has been associated with anti-inflammatory properties and may help in alleviating symptoms of certain gastrointestinal disorders such as irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD).

Lactobacillus species is a type of bacteria. There are lots of different species of lactobacillus.

Lactobacillus bacteria are commonly found in the human gut, mouth and vagina. They are considered generally as “good bacteria”, and in fact may contribute to good health, often being included in probiotic supplements. These bacteria are characterized by their ability to produce lactic acid as a byproduct of glucose metabolism.

Lactobacillus is a genus of gram-positive, facultative anaerobes. Species belonging to this genus normally colonise the mouth, gastrointestinal- and vaginal- tract of humans. They are also known as lactic acid bacteria since the main product of their metabolism is lactate and acetate. Lactobacillus reduce pathogen colonisation in the GI tract by lowering the pH and by producing antimicrobial compounds like reuterin. Species belonging to this genus are mostly considered beneficial for the organism, helping maintain homeostasis, and are considered probiotics. They help to reduce inflammation through immunomodulation; act on the nervous system and on gut permeability. They are also protective from early-life disorders such as autoimmune diseases, allergies and obesity.

What is Lactococcus?

Lactococcus is a genus of Gram-positive, lactic acid-producing bacteria that plays a prominent role in food fermentation and, to a lesser extent, in the human microbiome. You’ll often find Lactococcus species like Lactococcus lactis in fermented dairy products, including cheese, buttermilk, and yogurt.

While Lactococcus is not a dominant member of the gut microbiota, it is sometimes present in small amounts, especially in people who consume a lot of fermented foods or probiotic-rich diets. It is considered a non-pathogenic, commensal bacterium—meaning it generally coexists peacefully in the gut without causing harm.

On microbiome panels like the Vibrant Wellness Gut Zoomer, Lactococcus is measured to assess the presence of less-common, fermentation-associated microbes and to help identify patterns of microbial imbalance or overgrowth.

Lactoferrin and Calprotectin are reliable markers for differentiating organic inflammation (IBD) from function symptoms (IBS) and for management of IBD. Monitoring levels of fecal lactoferrin and calprotectin can play an essential role in determining the effectiveness of therapy, are good predictors of IBD remission, and can indicate a low risk of relapse.

The Lamb marker measures IgG antibodies to lamb proteins. Results are reported across ranges such as none detected, very low, low, moderate, or high. These categories reflect immune exposure and recognition rather than a true food allergy. Interpreting the result alongside symptoms, frequency of intake, and overall gut health can help determine whether lamb may be contributing to delayed digestive or inflammatory symptoms.
