Given the question: Information: - 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. - 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. - 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. - Granuloma inguinale ( also known as donovanosis ) is a bacterial disease caused by Klebsiella granulomatis characterized by ulcerative genital lesions . It is endemic in many less developed regions . It is also known as donovanosis , granuloma genitoinguinale , granuloma inguinale tropicum , granuloma venereum , granuloma venereum genitoinguinale , lupoid form of groin ulceration , serpiginous ulceration of the groin , ulcerating granuloma of the pudendum , and ulcerating sclerosing granuloma . The disease often goes untreated because of the scarcity of medical treatment in the countries in which it is found . In addition , the painless genital ulcers can be mistaken for syphilis . The ulcers ultimately progress to destruction of internal and external tissue , with extensive leakage of mucus and blood from the highly vascular lesions . The destructive nature of donovanosis also increases the risk of superinfection by other pathogenic microbes . Given the information above, choose from the list below the object entity that exhibits the relation 'medical specialty' with the subject 'granuloma inguinale'. Choices: - infectious disease - pathology
The answer is:
infectious disease
