Which items are measured in the Gut Microbiome Small test?

Escheria coli
Escherichia coli (E. coli) is a type of bacteria that is naturally found in the intestines of humans and other animals. It is a gram-negative, facultative anaerobic, rod-shaped bacterium that is a member of the Enterobacteriaceae family. E. coli is a beneficial bacteria that helps to break down food and produce vitamins. However, some strains of E. coli can cause food poisoning.
Escherichia coli Biovare
Escherichia coli Biovare, a distinct subspecies of E. coli, is unusual in the human intestine. It has several forms, including hemolytic, mucoid, and lactose-negative types. Finding hemolytic or mucoid E. coli is common, especially when there's an absence of beneficial E. coli and an alkaline pH level. Elevated levels of this subspecies can indicate inadequate mucosal immunity, often due to low production of secretory IgA.
Proteus is a genus of Gram-negative bacteria known for their ability to cause urinary tract infections (UTIs), particularly in people with long-term catheters or with a compromised immune system. They are also associated with wound infections and, less commonly, with respiratory system infections. Proteus bacteria are notable for their ability to resist multiple antibiotics, making infections challenging to treat.
Klebsiella is a genus of Gram-negative bacteria found in various environments, including soil, water, and the human gut. Some species, like Klebsiella pneumoniae, are significant pathogens, causing infections in the lungs (pneumonia), bloodstream, urinary tract, and wounds. Klebsiella bacteria are known for their antibiotic resistance, which complicates treatment options and is a major concern in healthcare settings.
Pseudomonas in stool can indicate an infection or overgrowth in the gastrointestinal tract. While not a common gut pathogen, Pseudomonas aeruginosa can cause problems, particularly in immunocompromised individuals. Its presence in stool may signal an imbalance in gut flora or a more serious underlying condition, especially when accompanied by gastrointestinal symptoms.
Enterobacter, a genus of common bacteria, can be found in the human gut. Typically harmless, they form part of the natural gut flora. However, in certain conditions, their overgrowth can indicate or cause health issues. Monitoring Enterobacter levels in stool can provide valuable insights into gut health and help diagnose various conditions.
Serratia, a type of bacteria often found in the environment, can also appear in the human intestinal tract. While it's generally harmless in healthy individuals, its presence in stool might be a concern for people with certain health conditions. Detecting Serratia in stool tests can indicate potential gut flora imbalances or infections.
Hafnia, a genus of bacteria typically found in the intestinal tract, is part of the normal gut flora. While generally harmless, its presence in stool can sometimes indicate digestive disturbances or an imbalance in gut microbiota.
Enterococcus, commonly found in the human intestines and part of the normal gut flora, plays a role in gut health. However, its overgrowth in stool can indicate an imbalance or potential infection, particularly in those with weakened immune systems.
Bifidobacterium is a crucial genus of bacteria that resides predominantly in the human gastrointestinal tract. These bacteria play a vital role in maintaining gut health, aiding in digestion, and boosting the immune system. They also help in the synthesis of essential vitamins and fighting harmful bacteria. A balanced presence of Bifidobacterium is key to a healthy gut microbiome.
Bacteroides spp. are a significant group of bacteria in the human gut microbiome. They play a vital role in breaking down complex carbohydrates and producing short-chain fatty acids, which are crucial for colon health. Bacteroides are also important for immune system regulation and protecting against harmful pathogens.
Lactobacillus is a beneficial bacteria commonly found in the gut and some fermented foods. It plays a crucial role in digestive health, aiding in nutrient absorption and supporting the immune system.
Clostridium refers to a genus of bacteria, some species of which are found naturally in the human gut, while others can cause illnesses. These bacteria can survive in harsh conditions due to their ability to form spores. While certain Clostridium species play a role in gut health, others, like Clostridium difficile, can lead to severe infections, especially after antibiotic use that disrupts the normal gut flora.
Candida spp
Candida spp includes various yeast-like fungi affecting body parts like the gut and vagina. These infections often cause itching, discomfort, and discharge. They result from flora imbalance. In the gut, Candida spp can disrupt digestion. This leads to bloating and changes in bowel habits. Diet, health, and antibiotics are contributing factors. Addressing these is crucial to restore balance and relieve symptoms.
Candida albicans
Candida albicans is a type of yeast that can affect various parts of the body, most commonly manifesting as vaginal yeast infections and gut overgrowth. Vaginal infections bring itching, discomfort, and discharge, often due to flora imbalance. In the gut, overgrown Candida albicans disrupts digestion, causing bloating and bowel habit changes. Diet, health, and antibiotics influence both conditions, requiring tailored treatments to restore balance and relieve symptoms.
Yeast, a type of fungus, is commonly found in the human body, especially in the gut and on the skin. In small amounts, it's harmless. However, imbalances can lead to overgrowth, causing various health issues. Factors like diet, antibiotics, and overall health influence yeast levels.
Geotrichum candidum
Geotrichum candidum is a type of fungus often found in soil, water, air, and some food products. In the human body, it's commonly present in the gut and on the skin. While typically harmless, Geotrichum candidum can cause issues in immunocompromised individuals.
pH value
The pH value of the stool can indicate if there are any conditions of excess decay or fermentation in the intestine. A too low pH value often occurs in combination with a dysfunctional intestinal flora, as complex sugars are metabolized to fatty acids, which can contribute to an acidified stool. A too high pH value can be due to excessive amounts of protein, which can stimulate certain intestinal bacteria to produce ammonia and other metabolic products, thus raising the pH value of the stool.
