Prompt antibiotic therapy usually succeeds in clearing bacteria from the bloodstream. (faqs.org)

Gastrointestinal flora are bacteria that live in your intestines. (healthline.com)
But it is surprising that this process is happening without microbial input, because bacteria in the gastrointestinal tract are also sources of chitinases that degrade chitin. (sciencedaily.com)
Van Dyken noted that in mice with intestinal bacteria, dietary chitin altered the bacterial composition in the lower gastrointestinal tract, suggesting that gut bacteria also adapt to chitin-containing food after it leaves the stomach. (sciencedaily.com)
Some affected children may develop bleeding within the gastrointestinal system. (rarediseases.org)
The physical barrier can be mechanical, chemical, or biological and located at different sites in the body including skin, secretions within the respiratory tract, and in the gastrointestinal or genitourinary tract as flora. (medscape.com)
The gastrointestinal tract serves as the primary site of nutrient absorption while it also harbours the highest load of commensal bacteria, representing a major portal of pathogen exposure. (lu.se)

The bacteria also activate the complement aspect of the immune system, generating a "find-me" signal to attract neutrophils. (gutnews.com)
activate a group of proteins called complement that are part of the immune system. (kidshealth.org)

The gene provides resistance to colistin, an antibiotic with nasty side effects used to combat multidrug-resistant bacteria. (scienceblogs.com)
Antibiotic - a medicine that fights and kills bacteria to help you feel better. (acs.org)
Antibiotic resistance - when bacteria can no longer be killed by a certain antibiotic. (acs.org)

With RA, your immune system mistakenly attacks your own body, primarily your joints. (medicalnewstoday.com)

B lymphocytes are like the body's military intelligence system - they find their targets and send defenses to lock onto them. (kidshealth.org)
It plays a crucial role in all major physiological processes by supplying antioxidant defenses through participating in cellular redox reactions in the human body and other living organisms. (bvsalud.org)
Also, weakened defenses of the body by the immune system due to genetic, acquired causes precipitate an inherent state of anergy (unresponsiveness) that can lead to immunodeficiency diseases. (medscape.com)

data on the use of GSH for medicinal purposes in the prevention and treatment of some diseases, as well as a nutritional strategy to maintain a normal pool of GSH in the body. (bvsalud.org)

The dead macrophage shields the Salmonella from the antimicrobial properties of the neutrophil, allowing the bacteria to survive. (gutnews.com)

The UCSF-based team first examined whether components of these bacteria could regulate T lymphocyte-mediated adaptive immune responses. (genomeweb.com)
It can also enhance metabolic detoxification and regulate the function of the immune system. (bvsalud.org)

In two independent studies, scientists at the University of Basel have demonstrated that both the structure of the brain and several memory functions are linked to immune system genes. (unibas.ch)
Scientists from the University of Basel's Transfaculty Research Platform Molecular and Cognitive Neurosciences (MCN) have now carried out two independent studies that demonstrate that this link between the immune system and brain is more significant than previously believed. (unibas.ch)
Other scientists believe that running causes carcinogens to flush out of the body through increased sweat and urine loss. (rtpr.com)

But when neutrophils engage in attack, the acids produced by the oral bacteria demineralize the tooth. (utoronto.ca)

One type of phagocyte is the neutrophil (pronounced: NOO-truh-fil), which fights bacteria. (kidshealth.org)

An active immune response was linked to less weight gain, reduced body fat and a resistance to obesity. (sciencedaily.com)
They are a natural part of our immune system, and development of resistance against them seem to be rather low. (lu.se)

Workspaces can harbour pollutants such as viruses, bacteria, Volatile Organic Compounds (VOCs), pollen and formaldehyde. (dyson.co.uk)

Once your body has developed a reaction to a particular agent (allergen) - in this case, nickel - your immune system will always be sensitive to it. (mayoclinic.org)
When it recognizes an allergen, the immune system launches a response. (medlineplus.gov)
Mostly, the part of the body the allergen touches affects what symptoms you develop. (medlineplus.gov)

Because nickel is common in jewelry, nickel allergy is most often associated with earrings and other body-piercing jewelry containing nickel. (mayoclinic.org)
At times, an allergy can trigger a response that involves the entire body. (medlineplus.gov)

A rise in body temperature can help to kill some microbes. (melaleuca.com)

The lymphatic system is a network of delicate tubes throughout the body. (melaleuca.com)
They are made in your bone marrow and are part of the lymphatic system. (melaleuca.com)
The cardiovascular system and the lymphatic system form what is collectively called the circulatory system . (encyclopedia.com)
the lymphatic system aids it in its function. (encyclopedia.com)
