Fusobacterium

Gut Zoomer by Vibrant Wellness, Vibrant Wellness

Optimal range:   0 - 20 Units

Genus of gram-negative bacteria in the Fusobacteria phylum. Commonly found in the oral cavity, and may also be found in the intestine. Associated with inflammatory processes, as well as autoimmune conditions such as systemic sclerosis.

Autoimmune Association: Systemic sclerosis or inflammatory bowel disease

Fusobacterium in the gut microbiome is noteworthy due to its association with various gastrointestinal conditions. Its balance is influenced by factors like diet, oral health, and gut microbiota composition. Managing its levels involves dietary and oral hygiene interventions, and potentially probiotic supplementation and medical treatments, all aimed at maintaining a healthy and diverse gut microbiome.

Fusobacterium species

The GI – Advanced Profile (US BioTek), US BioTek

Optimal range:   0 - 10 x10^4 CFU/g

The marker Fusobacterium species refers to a group of bacteria that are part of the normal flora in the human gut but can also act as pathogens under certain conditions. Fusobacterium species are anaerobic bacteria, meaning they thrive in environments with little to no oxygen, such as the deeper layers of the mucous membrane lining the gut. In a healthy individual, these bacteria coexist peacefully with other microorganisms and contribute to the gut's ecological balance. However, if the balance is disrupted, Fusobacterium can become opportunistic pathogens, leading to infections. The presence of these bacteria in elevated levels on a GI panel can indicate an infection or dysbiosis (an imbalance in the microbial community), which may be associated with various gastrointestinal disorders, including inflammatory bowel disease and colon cancer. Therefore, the detection of Fusobacterium species on a GI panel is crucial for diagnosing potential infections or imbalances, guiding effective treatment plans to restore gut health.

Fusobacterium spp.

2200 GI Effects Comprehensive Profile - Stool, Genova Diagnostics

Optimal range:   0 - 180000 CFU/g stool

Fusobacterium spp. present in the oral and gut flora is carcinogenic and is associated with the risk of pancreatic and colorectal cancers. Fusobacterium spp. is also implicated in a broad spectrum of human pathologies, including Crohn’s disease and ulcerative colitis (UC).

Fusobacterium is very rarely found among the usual gut bugs, but it appears to flourish in colon cancer cells.

G- Aminobutyr. acid /g Krea.

Urinary Amino Acids (Synlab), SYNLAB

Optimal range:   0 - 1 mmol/mol creatinine

Gamma-aminobutyric acid (GABA) is an amino acid that functions as an inhibitory neurotransmitter. It serves one-third of brain neurons and is involved in depression and mania.

Although there are some dietary supplement and food sources for GABA (cruciferous vegetables, spinach, tomatoes, beans, and rice), the primary source may be endogenous prodution. Nervous tissue, the gut microbiome, the liver, pancreas, and endothelial cells are important sources for production.

G-6-PD, Quant

LabCorp (various), LabCorp

Optimal range:   127 - 427 U/10E12 RBC

This test measures the amount of G6PD in red blood cells to help diagnose a G6PD deficiency.

G6PD deficiency is an inherited condition. It is when the body doesn’t have enough of an enzyme called G6PD (glucose-6-phosphate dehydrogenase).

This enzyme helps red blood cells work correctly. A lack of this enzyme can cause hemolytic anemia. This is when the red blood cells break down faster than they are made.

G-6-PD, RBC

Blood

Quest Diagnostics, Quest Diagnostics

Optimal range:   7 - 20.5 U/g Hgb

Glucose-6-phosphate dehydrogenase (G6PD) is an enzyme essential for energy production and found in all cells, including red blood cells (RBCs), where it safeguards them from toxic by-products of metabolism. A G6PD deficiency, a genetic disorder affecting over 400 million people worldwide, can lead to RBCs becoming susceptible to breaking apart (hemolysis), particularly when triggered by factors like stress, infections, drugs, or certain substances, like fava beans.
