• Enterococcus: Contributes to a healthy gut environment and assists in the digestion process, converting food into energy.
• Escherichia (E. Coli): Certain strains can be harmful, while others are helpful, maintaining the integrity of the intestinal barrier and preventing infections.
• Lactobacillus: Needed to maintain a healthy balance of gut flora, warding off pathogens, and aiding in digestion.
• Akkermansia mucinophila: Helps reinforce the mucous layer in the gut, acting as a protective barrier and playing a role in metabolic processes. Imbalances of Akkermansia can lead to unexplained weight gain.

• Giardia: Causes giardiasis, characterized by symptoms such as foul-smelling diarrhea, stomach cramps, bloating, and nausea.

• H. Pylori: Known for causing ulcers in the stomach lining and increasing the risk of stomach cancer. This pathogen is also linked to chronic gastritis and peptic ulcers. Pro Knowledge: It can also slow stomach acid production, leading to fermentation and bubbling of food in the stomach, which can then lead to acid reflux.
• Virulence Factor, cagA: A protein associated with H. pylori, which increases its ability to cause damage and leads to more severe gastric diseases.
• Virulence Factor, vacA: A toxin produced by H. pylori that can lead to cell death in the stomach lining and contribute to ulcer formation.

• Citrobacter freundii: Can cause infections in the urinary tract and other parts of the body, may trigger symptoms in autoimmune conditions.
• Klebsiella pneumoniae: Known to cause pneumonia, it can also lead to other infections, particularly in individuals with weakened immune systems like autoimmune disease.
• Proteus: A group of bacteria that can cause urinary tract infections and may be linked to rheumatoid arthritis.
• Proteus mirabilis: This specific strain is also associated with urinary tract infections and could be implicated in kidney stone formation.
• Methanobacteriaceae: A family of bacteria that produces methane, which can negatively affect the overall balance of the gut microbiome.
• Fusobacterium: These bacteria are associated with several infections, including periodontal disease (like gum disease), and may have links to colorectal cancer.
• Desulfovibrio: Known for producing hydrogen sulfide, which can damage the gut lining and is associated with inflammatory bowel diseases (IBD).

• Morganella: Normally found in the human intestine, but if it overgrows, it can cause infections, particularly in the urinary tract.
• Pseudomonas: Known for its resistance to antibiotics and can cause various infections if it overgrows.
• Pseudomonas aeruginosa: A specific strain of Pseudomonas that can lead to respiratory system infections and is particularly problematic in hospitals.
• Staphylococcus: Can cause skin infections, pneumonia, and food poisoning when they overpopulate.
• Streptococcus: Can cause a wide range of health issues, from strep throat to more serious conditions like rheumatic fever if it grows unchecked.

• Blastocystis hominis: Commonly found in the intestine; can sometimes cause digestive symptoms, but many people have no symptoms at all.
• Dientamoeba fragilis: May cause diarrhea, bloating, and stomach pain, although it is often found in people who have no digestive symptoms.
• Endolimax nana: Usually doesn’t cause problems but can be associated with gastrointestinal symptoms if they overgrow.
• Entamoeba coli: Not to be confused with E. coli bacteria, this parasite is typically harmless but can sometimes be a sign of poor sanitary conditions.
• Chilomastix mesnelli: Often found in the human digestive tract and usually doesn’t cause disease or symptoms but still is important in the overall microbiome.
• Pentatrichomonas hominis: Considered non-disease causing, but its presence may indicate exposure to other pathogens or poor hygiene.

• Candida albicans: This yeast can cause infections like thrush and yeast infections, particularly in individuals with weakened immune systems like autoimmunity.
• Candida: Similar to Candida albicans, these species can lead to various candidiasis infections, affecting skin, genitals, throat, and more.

• Eosinophil Activation Protein (EPX/EDN): This test looks for proteins released by eosinophils, a type of white blood cell, indicating allergic reactions or parasitic infections.
• Calprotectin: Measures a protein found in white blood cells in stool to detect inflammation in the intestines, useful in diagnosing conditions like IBD.
• b-Glucuronidase: An enzyme measurement that can indicate the general health of the gut flora and potential for toxin buildup. High levels can also cause hormone imbalances due to its ability to cause discarded hormones in the stool to be reabsorbed.
• Steatocrit: This test measures the amount of fat in stool to assess for conditions that affect fat absorption, like pancreatic insufficiency.
• Fecal Occult Blood: Tests for hidden (occult) blood in the stool, an early marker for colon cancer or other gastrointestinal disorders.

This part of the GI Map stool test shows doctors if certain bacteria in your body are resistant to antibiotics. For example, H. Pylori, a bacteria that can live in the stomach and can slow stomach acid production, might not be stopped by some drugs if the test indicates “Positive” for resistance genes. Here are the 4 drugs that are used in the gene resistance testing:

• Amoxicillin
• Fluoroquinolones
• Clarithromycin
• Tetracycline

Here is a sample report for the GI Map’s antibiotic-resistant gene test. You can also review the sample of the full GI Map test results.
