- One of the most common viruses worldwide; infects 90–95% of the population

- Commonly contracted in childhood and causes mild symptoms

The Estrogen Quotient is a simple ratio of the cancer protective E3 relative to the proliferative estrogens E1 and E2, to assess breast cancer risk.

The higher your E3 is compared to your E1 and E2 levels, the lower your cancer risks may be. 

- Equol is a bacterial-derived metabolite with estrogenic and antioxidant activity. Reductase enzymes secreted by the gut microbiota convert daidzein into equol. Daidzein is an isoflavone from soy, tofu, soy milk, tempeh, miso.

- The ability to produce equol varies among individuals because only people who possess the intestinal bacteria capable of producing equol are regarded as equol producers. Vegetarians reported significantly higher rates of equol production.

- Spot-urine equol levels have been found to correlate strongly with serum concentrations.

- Women with PMS had a significantly higher risk of being an equol nonproducer. Intake of daidzein from soy has been associated with reductions of estrogen-dependent and aging-associated disorders. Isoflavonoid-rich herbal supplement (included daidzein) improved intima-media thickness of carotid arteries (CIMT) and inhibited growth of existing atherosclerotic plaques of postmenopausal women.

The ermB gene, included in the Urinary Tract Infection Panel by RealTime Laboratories, is a significant marker for antibiotic resistance, particularly relevant in the context of urinary tract infections (UTIs). This gene is responsible for conferring resistance to macrolide antibiotics, which include erythromycin, clarithromycin, and azithromycin, through a mechanism known as ribosomal methylation. The presence of the ermB gene in urinary pathogens is a critical factor in determining the appropriate antibiotic therapy, as it indicates the potential ineffectiveness of macrolide antibiotics.

The erythrocyte sedimentation rate (ESR or sed rate) is a relatively simple, inexpensive, non-specific test that has been used for many years to help detect inflammation associated with conditions such as infections, cancers, and autoimmune diseases.

Erythrocytes (red blood cells) are typically absent in cerebrospinal fluid (CSF) under normal conditions. Their presence can indicate a subarachnoid hemorrhage (bleeding in the brain), traumatic lumbar puncture (blood contamination during CSF collection), or other conditions such as CNS trauma, severe infections, or tumors causing blood vessel damage. Differentiating between true hemorrhage and a traumatic puncture often involves testing for xanthochromia (a yellow discoloration from hemoglobin breakdown) and analyzing sequential CSF samples for a decreasing erythrocyte count. Elevated erythrocytes in CSF require further evaluation with imaging or additional tests to determine the underlying cause and guide appropriate treatment.

Erythropoietin, also known as EPO, is a hormone that the kidneys produce to stimulate production and maintenance of crucial red blood cells. The hormone does this in two ways: First, it stimulates bone marrow cells to produce red blood cells. Then, it works to protect the cells from destruction once they are in the body.

Escherichia coli, commonly known as E. coli, is a significant bacterium often identified in urine culture panels, especially in the context of urinary tract infections (UTIs). This rod-shaped, Gram-negative bacterium is part of the normal flora of the human gut, but when it spreads to the urinary tract, it becomes a primary pathogen causing discomfort and health issues. A urine culture panel is a critical diagnostic tool used to detect and identify bacteria in urine samples, particularly E. coli, which is responsible for approximately 80-90% of UTIs. The presence of E. coli in a urine culture is a clear indication of infection, necessitating prompt and appropriate antibiotic treatment.

Escherichia coli (E. coli) is a type of bacteria that normally live in the intestines of people and animals.

Escherichia coli, commonly known as E. coli, is a diverse group of bacteria that typically live in the intestines of humans and animals. Most strains of E. coli are harmless and play an important role in maintaining a healthy gut microbiome. However, some pathogenic strains can cause serious infections, particularly in the urinary tract, gastrointestinal system, and bloodstream. These pathogenic strains can be acquired through contaminated food or water and may result in symptoms such as diarrhea, abdominal pain, and, in severe cases, kidney failure.

Escherichia coli (E. coli) is a normal gut bacterium that plays a role in digestion, vitamin production, and microbial balance. While many strains are harmless or beneficial, certain strains can become problematic when levels rise. Low or high E. coli may indicate dysbiosis, recent infection, inflammation, or changes in digestive health.

Escherichia coli Nissle is a Gram-negative strain with many prominent probiotic properties in the treatment of intestinal diseases such as diarrhea and inflammatory bowel disease (IBD), in particular ulcerative colitis.

Escherichia coli Nissle not only exhibits antagonistic effects on a variety of intestinal pathogenic bacteria, but also regulates the secretion of immune factors in vivo and enhances the ability of host immunity.

E. coli O157 is a member of the pathogenic enterohemorrhagic E. coli strains (also known as verocytotoxin producing or Shiga-toxin producing E. coli (STEC)), and is an uncommon but serious cause of gastroenteritis. Infection with E. coli O157 often causes hemorrhagic colitis which involves severe abdominal cramps with watery non-hemorrhagic diarrhea which can become grossly bloody after two or three days. 

Escherichia species, prominently Escherichia coli (E. coli), are a significant aspect of gastrointestinal (GI) test results due to their diverse roles within the human gut and potential implications for health. E. coli is a common and typically harmless resident of the human intestinal tract, playing a crucial role in maintaining the gut's microbial balance. However, certain strains of E. coli can be pathogenic, leading to various gastrointestinal and extraintestinal diseases. When a GI test indicates elevated or abnormal levels of E. coli, it may signal an infection or a disruption in the gut microbiome's equilibrium.

Enterococcus species, commonly detected in gastrointestinal (GI) tests, represent a significant group of bacteria naturally inhabiting the human gut. These species, particularly Enterococcus faecalis and Enterococcus faecium, are noteworthy for their dual nature: while being normal constituents of the intestinal microbiota, they can also act as opportunistic pathogens. Their presence in GI tests can sometimes be indicative of a healthy, balanced gut flora, but their overgrowth or presence in certain clinical contexts can signal an imbalance or an infection.
