Question: Information:  - Immunodeficiency (or immune deficiency) is a state in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. Most cases of immunodeficiency are acquired ("secondary") due to extrinsic factors that affect the patient's immune system. Examples of these extrinsic factors include HIV infection, extremes of age, and environmental factors, such as nutrition. In the clinical setting, the immunosuppression by some drugs, such as steroids, can be either an adverse effect or the intended purpose of the treatment. Examples of such use is in organ transplant surgery as an anti-rejection measure and in patients suffering from an overactive immune system, as in autoimmune diseases. Some people are born with intrinsic defects in their immune system, or primary immunodeficiency. A person who has an immunodeficiency of any kind is said to be immunocompromised. An immunocompromised person may be particularly vulnerable to opportunistic infections, in addition to normal infections that could affect everyone. Immunodeficiency also decreases cancer immunosurveillance, in which the immune system scans the body's cells and kills neoplastic ones.  - A prion ( i / prin / ) is an infectious agent thought to be the cause of the transmissible spongiform encephalopathies ( TSEs ) . It is composed entirely of protein material , called PrP ( short for prion protein ) , that can fold in multiple , structurally distinct ways , at least one of which is transmissible to other prion proteins , leading to disease that is similar to viral infection . The word prion , coined in 1982 by Stanley B. Prusiner -- derived from the words protein and infection , hence prion -- is short for `` proteinaceous infectious particle '' , in reference to its ability to self - propagate and transmit its conformation to other proteins . Prions were initially identified as the causative agent in animal TSEs such as bovine spongiform encephalopathy ( BSE ) -- known popularly as `` mad cow disease '' -- and scrapie in sheep . Human prion diseases include Creutzfeldt - Jakob Disease ( CJD ) and its variant ( vCJD ) , Gerstmann -- Sträussler -- Scheinker syndrome , Fatal Familial Insomnia , and kuru . A recent study concluded that multiple system atrophy ( MSA ) , a rare human neurodegenerative disease , is caused by a misfolded version of a protein called alpha - synuclein , and is therefore also classifiable as a prion disease . Several yeast proteins have been identified as having prionogenic properties as well . A protein as a standalone infectious agent stands in contrast to all other known infectious agents such as viruses , bacteria , fungi , and parasites , all of which contain nucleic acids ( DNA , RNA , or both ) . For this reason , a minority of researchers still consider the prion / TSE hypothesis unproven . All known prion diseases in mammals affect the structure of the brain or other neural tissue ; all are currently untreatable and universally fatal . Prions may propagate by transmitting their misfolded protein state : When a prion enters a healthy organism , it induces existing , properly folded proteins to convert into the misfolded prion form . In this way , the prion acts...  - Pathology (from the Greek roots of "pathos", meaning "experience" or "suffering", and "-logia", "study of") is a significant component of the causal study of disease and a major field in modern medicine and diagnosis.  - A disease is a particular abnormal condition, a disorder of a structure or function, that affects part or all of an organism. The study of disease is called pathology which includes the causal study of etiology. Disease is often construed as a medical condition associated with specific symptoms and signs. It may be caused by external factors such as pathogens, or it may be caused by internal dysfunctions particularly of the immune system such as an immunodeficiency, or a hypersensitivity including allergies and autoimmunity.    Given the information above, choose from the list below the object entity that exhibits the relation 'medical specialty' with the subject 'prion'.  Choices: - infection  - infectious disease  - pathology
Answer: infectious disease

The stadium holds 8,000 people.  - Burkina Faso is a landlocked country in Africa around in size. It is surrounded by six countries: Mali to the north; Niger to the east; Benin to the southeast; Togo and Ghana to the south; and Ivory Coast to the southwest. Its capital is Ouagadougou.
