Phocaeicola vulgatus

Optimal result: 0 – 830000000 CFU/g stool

If your GI test shows elevated levels of Phocaeicola vulgatus, it may indicate an imbalance in your gut microbiome. Phocaeicola vulgatus is a type of bacterium normally present in the human gut, but elevated levels can sometimes be associated with conditions like irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), or other gastrointestinal disorders. An imbalance, or dysbiosis, can disrupt the normal function of your gut, leading to symptoms such as bloating, abdominal pain, diarrhea, or constipation.

Treatment options to address elevated levels of Phocaeicola vulgatus and restore gut balance include:

  1. Probiotics: Taking probiotic supplements can help introduce beneficial bacteria to your gut, potentially restoring a healthier balance of microorganisms.

  2. Prebiotics: These are non-digestible fibers that promote the growth of beneficial bacteria in the gut. Foods rich in prebiotics, like garlic, onions, bananas, and whole grains, can support this process.

  3. Dietary Changes: Adjusting your diet to reduce the intake of foods that may contribute to dysbiosis can be helpful. This might include reducing processed foods, sugars, and certain fats, and increasing the intake of fiber-rich foods, fruits, vegetables, and fermented foods.

  4. Antibiotics: In some cases, a healthcare provider might prescribe antibiotics to reduce harmful bacterial overgrowth. However, this is typically a last resort as antibiotics can also affect beneficial bacteria.

  5. Fecal Microbiota Transplantation (FMT): For severe cases, FMT may be considered. This involves transplanting stool from a healthy donor to restore a balanced gut microbiome.

  6. Lifestyle Changes: Stress management, regular physical activity, and adequate sleep can also contribute to a healthier gut microbiome.

It's important to work closely with your healthcare provider to develop a personalized treatment plan. They may recommend specific tests, dietary adjustments, or other interventions based on your individual health needs and the underlying cause of the imbalance. If you have any questions or concerns about your test results or treatment options, please don't hesitate to discuss them with your healthcare provider.

A high beef diet was associated with increases in Bacteroides fragilis, B. vulgatus and Clostridium spp. in 10 volunteers.

Decreased levels were found in 7-12- year olds who consumed oligofructoseenriched inulin (BENEO's prebiotic fiber Synergy1) for 16 weeks in a double-blind-controlled trial.

Dietary inulin-type fructan prebiotics decreased Bacteroides vulgatus in obese women which positively correlated with changes in body composition and glucose homeostasis.

Generally considered a beneficial gut commensal, although is capable of attaching to and invading colonic epithelial cells and inducing pro-inflammatory cytokines.

- Produces beta-glucuronidase, succinate, lactate, acetate, formate, and propionate.

- Associated with insulin resistance.

- Contains bile salt hydrolases to metabolize bile.

- Formerly named Bacteroides vulgatus.

"Watching my numbers move over the years — instead of forgetting last time's results — completely changed how I manage my health."

"Living across several countries made keeping my lab results organized a real challenge. Healthmatters brought my results from the USA, Spain, and Germany together — 20 years of history, with long-term trends instead of scattered reports."

"Standard lab ranges are too wide for how I practice — 'normal' isn't optimal. I set my own bands, so a client sees yellow before a marker goes officially out of range. That's the conversation I want to be having."
