Bifidobacterium longum

Optimal Result: 5.2 - 1000 x10^5 CFU/g.

Bifidobacterium longum is a specific species of microscopic non-pathogenic bacteria found naturally in the gastrointestinal tracts of humans as well as in most other animals. It is added to a variety of foods or dietary supplements as a probiotic due to its many health benefits. It is a gram-positive, branched rod-shaped bacterium that produces lactic acid from the fermentation of sugar in the gastrointestinal tract.

What does it mean if your Bifidobacterium longum result is too low?

Bifidobacterium longum is one of the key species of Bifidobacterium found in the human gastrointestinal tract. It's considered a beneficial bacterium due to its role in maintaining gut health and producing essential compounds.

Low levels of Bifidobacterium longum in the colon can be indicative of several things:

→ Diet: Bifidobacterium species thrive on a diet rich in prebiotics, which are specific types of dietary fiber that serve as food for beneficial bacteria. A diet low in fiber and high in fats, sugars, and processed foods may not provide the necessary substrates for B. longum to thrive, leading to reduced levels.

→ Age: Bifidobacterium, including B. longum, is typically abundant in infants, particularly in those who are breastfed. Its levels tend to decrease with age, with adults generally having lower levels than infants.

→ Antibiotic Use: Antibiotics can significantly impact the gut microbiome composition, often reducing the abundance of many beneficial bacteria, including B. longum.

→ Gastrointestinal Health: Lower levels of B. longum might be associated with several GI conditions, including irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD). B. longum has been researched for its potential role in alleviating symptoms of these conditions due to its anti-inflammatory properties.

→ Immune Function: B. longum is involved in modulating the immune system, enhancing barrier function, and inhibiting the growth of harmful pathogens. Lower levels might be linked with impaired immune function and increased susceptibility to infections.

→ Mental Health and Stress: Some studies suggest that B. longum can influence the gut-brain axis, potentially impacting mood and behavior. Stress and certain mental health conditions might be associated with alterations in the levels of B. longum and other gut bacteria.

→ Geographic and Lifestyle Differences: Geographic location, sanitation, and other lifestyle factors can influence the gut microbiome's composition. Some populations or individuals might naturally have different baseline levels of B. longum due to these factors.

It's essential to interpret the levels of B. longum in the context of the overall microbiome profile and an individual's health, diet, and lifestyle. Low levels alone don't necessarily indicate a problem, but if associated with other imbalances or health issues, interventions might be considered.
