What is Bifidobacterium spp.? High and low values | Lab results explained

Bifidobacterium bacteria are regarded as a vital part to infant health. They are supposed to prevent the growth of disease-causing bacteria. Mother’s milk can help increase the development of Bifidobacterium. As the microbiome matures, Bifidobacterium decreases, and although it is a genus commonly found in the adult gut, its overall level generally makes up less than 3% of an individual’s total bacterial load.

The Bifidobacterium species are non-pathogenic, and are deliberately added to some food products because of their beneficial probiotic health effects.

These effects include better lactose tolerance, the prevention of diarrhea, a reduction in food allergies, and (as is also the case in infants) the inhibition of the growth of pathogenic organisms.

Higher levels:

– Increased levels seen in obese subjects compared to lean/overweight

Lower levels:

– A lower abundance has been associated with Irritable Bowel Syndrome.

– The amount of Bifidobacterium has also been measured at lower levels after weight-loss and gastric bypass surgery.

– Lower levels also measured in people with IBD and IBS.

– Lower levels seen in type 2 diabetes

– Lower levels seen in pediatric allergy

– Lower levels seen in autism

– Infants with lower Bifidobacterium may have increased risk for weight gain in childhood
