An individual either has, or does not have, the "Rhesus factor" on the surface of their red blood cells. This term strictly refers only to the most immunogenic D antigen of the Rh blood group system, or the Rh- blood group system. The status is usually indicated by Rh positive (Rh+ does have the D antigen) or Rh negative (Rh- does not have the D antigen) suffix to the ABO blood type

the spread of a disease from one organ or part to another non-adjacent organ or part.[
refers to undesirable reactions produced by the normal immune system, including allergies and autoimmunity. These reactions may be damaging, uncomfortable, or occasionally fatal.
the formation of antigen-antibody complexes. formed from the integral binding of an antibody to a soluble antigen.
the failure of an organism in recognizing its own constituent parts as self, which allows an immune response against its own cells and tissues. The loss of self tolerance.

the transplantation of cells, tissues, or organs, to a recipient from a (genetically non-identical) donor of the same species.
the transplantation of organs, tissues or even proteins from one part of the body to another in the same individual.
the transplantation of living cells, tissues or organs from one species to another.
the common chronic inflammatory disease of the airways characterized by variable and recurring symptoms, reversible airflow obstruction, and bronchospasm.
an antigen capable of stimulating a type-I hypersensitivity reaction in atopic individuals through Immunoglobulin E (IgE) responses.
an organic nitrogen compound involved in local immune responses as well as regulating physiological function in the gut and acting as a neurotransmitter; triggers the inflammatory response.
a state in which the immune system's ability to fight infectious disease is compromised or entirely absent; the body is incapable of making or sustaining an adequate immune response.

a large Y-shaped protein produced by B-cells that is used by the immune system to identify and neutralize foreign objects such as bacteria and viruses. The antibody recognizes a unique part of the foreign target, called an antigen
a medical term for a tiny collection of immune cells known as macrophages; form when the immune system attempts to wall off substances that it perceives as foreign but is unable to eliminate.
a condition in which the eye's cornea, the front part of the eye, becomes inflamed. The condition is often marked by moderate to intense pain and usually involves impaired eyesight.
a layer of skin between the epidermis (with which it makes up the cutis) and subcutaneous tissues, that consists of connective tissue and cushions the body from stress and strain
composed of the outermost layers of cells in the skin
the presence of bacteria in the blood. Can also be defined as a medical condition in which hypertension arises in pregnancy (pregnancy-induced hypertension) in association with significant amounts of protein in the urine.
a form of anthrax infection acquired by inhalation of dust containing Bacillus anthracis; initial symptoms (chill and cough and dyspnea and rapid pulse) are followed by extreme cardiovascular collapse
refers to the practice, in medicine, of avoiding contact with patients' bodily fluids, by means of the wearing of nonporous articles such as medical gloves, goggles, and face shields.
Diabetes mellitus type I
results from autoimmune destruction of insulin-producing beta cells of the pancreas.
an autoimmune disease where the thyroid is overactive, producing an excessive amount of thyroid hormones (a serious metabolic imbalance known as hyperthyroidism and thyrotoxicosis
an autoimmune disease in which the thyroid gland is gradually destroyed by a variety of cell- and antibody-mediated immune processes.
an inflammatory disease in which the fatty myelin sheaths around the axons of the brain and spinal cord are damaged, leading to demyelination and scarring as well as a broad spectrum of signs and symptoms. Disease onset usually occurs in young adults, and it is more common in women. It has a prevalence that ranges between 2 and 150 per 100,000.
an autoimmune neuromuscular disease leading to fluctuating muscle weakness and fatiguability. It is an autoimmune disorder, in which weakness is caused by circulating antibodies that block acetylcholine receptors at the postsynaptic neuromuscular junction, inhibiting the excitatory effects of the neurotransmitter acetylcholine on nicotinic receptors throughout neuromuscular junctions.
Systemic Lupus Erythematosis
systemic autoimmune disease (or autoimmune connective tissue disease) that can affect any part of the body. As occurs in other autoimmune diseases, the immune system attacks the body's cells and tissue, resulting in inflammation and tissue damage. It is a Type III hypersensitivity reaction caused by antibody-immune complex formation.
a chronic, systemic inflammatory disorder that may affect many tissues and organs, but principally attacks flexible (synovial) joints. The process produces an inflammatory response of the capsule around the joints (synovium) secondary to swelling (hyperplasia) of synovial cells, excess synovial fluid, and the development of fibrous tissue (pannus) in the synovium. The pathology of the disease process often leads to the destruction of articular cartilage and ankylosis of the joints.
an incurable form of vasculitis (inflammation of blood vessels) that affects the nose, lungs, kidneys and other organs. Due to its end-organ damage, it is life-threatening and requires long-term immunosuppression.[
a failure of the body's defense, including the immune system
hair follicle infection that spreads into surrounding tissue, generating an abcess.
a contagious skin infection of children caused by Staph Aureus or Strept pyrogenes; causes thin-walled abcesses that look like blisters or "weeping lesions with scabs.
(flesh-eating disease) primarily caused by a toxin of Strept pyrogenes. organism is spread along the fascia and must be treated very agressively with removal of infected tissue and antibiotics. 50% fatality

Herpes Simplex Virus
usually associated with skin infections above the waist (exception would be oral sex) and is spread by direct contact. Once th lesion resolves the virus becomes latent in nerve ganglia and can be reactiviated during the physical/psychological stress, certain foods, exposure to sun, etc. Typical type I lesions are singular. VIRUS WILL ALWAYS BE PRESENT.

Humans are infected through animal bites, scratches, punture wounds contaminated with dirt containing spore. Causes muscle spasms leading to paralysis (lockjaw) with CNS damage. Can be prevented with tetanus shot (every 7-10 years).
a toxemia caused by Bacillus anthracis, a spore-forming gram-positive rod which usually causes diseases in grazing animals, but can be transmitted to humans through skin wounds or inhalation of spores. formerly called "woolsorters disease". Can be treated with antibiotics, however, the pulmonary form of anthrax is usually fatal.
