medications capable of inhibiting growth or killing pathogenic bacterial microorganisms.
32

a disease-fighting protein created by the immune system in response to the presence of a specific antigen.
33
antifungal
an agent that destroys or inhibits the growth of fungi.
34
antigen–antibody reaction
also known as the immune reaction, involves binding antigens to antibodies.
35
autoimmune disorder
also known as an autoimmune disease, is any of a large group of diseases characterized by a condition in which the immune system produces antibodies against its own tissues, mistaking healthy cells, tissues, or organs for antigens.
36
bacilli
rod-shaped, spore-forming bacteria. (The singular is bacillus).
37
bacteria
one-celled microscopic organisms (singular, bacterium).
38
candidiasis
also known as a yeast infection. Yeast infections occur on the skin or mucous membranes in warm, moist areas such as the vagina or mouth and are caused by the pathogenic yeast Candida albicans.
39
complement system
a group of proteins that normally circulate in the blood in an inactive form.
40
COVID-19
a highly contagious viral infection caused by the SARS-CoV-2 virus.
41
cytokines
a group of proteins such as interferons and interleukins released primarily by the T cells
42
cytomegalovirus
(CMV) is found in most body fluids.
43
hemolytic
destroying worn-out erythrocytes (red blood cells) and releasing their hemoglobin for reuse.
44
herpes zoster
(HZ), commonly known as shingles, is an acute viral infection characterized by painful skin eruptions that follow the underlying route of an inflamed nerve.
45
human immunodeficiency virus
commonly known as HIV, is a bloodborne infection in which the virus damages or kills the T cells of the immune system, causing it to progressively fail, thus leaving the body at risk of developing many life-threatening opportunistic infections.
46
immunodeficiency disorder
occurs when the immune response is compromised.
47
immunoglobulins
bind with specific antigens in the antigen–antibody response. The five primary types of immunoglobulins, which are secreted by plasma cells, are also known as antibodies.
48
immunologist
specializes in diagnosing and treating disorders of the immune system.
49
immunosuppressant
a substance that prevents or reduces the body’s normal immune response.
50
immunotherapy
also called biological therapy, is a disease treatment that involves either stimulating or repressing the immune response.
51
infectious disease specialist
a physician who specializes in diagnosing and treating diseases caused by microorganisms such as viruses, bacteria, and parasites.
52
infectious mononucleosis
also known as mono, is caused by the Epstein-Barr virus, and is most common in adolescents and young adults.
53
influenza
commonly known as the flu, is a highly contagious viral respiratory infection that usually occurs in seasonal epidemics.
54
interferons
(IFNs) are produced in response to the presence of antigens, particularly viruses or tumor cells.
55

a physician who specializes in diagnosing and treating disorders of the lymphatic system.
61
lymphoscintigraphy
a diagnostic test that is performed to detect damage or malformations of the lymphatic vessels.

a type of leukocyte that surrounds and kills invading cells.
63

caused by a parasite that lives in certain mosquitoes and is transferred to humans by the bite of an infected mosquito
64
measles
an acute, highly contagious infection that is transmitted by respiratory droplets of the rubeola virus.
65
natural immunity
which is also known as passive immunity, is resistance to a disease present without the administration of an antigen or exposure to a disease.
66
opportunistic infection
caused by a pathogen that does not normally produce an illness in healthy humans.
67
parasite
a plant or animal that lives on or within another living organism at the expense of that organism.

a microorganism that causes a disease in humans.

71
rubella
also known as German measles, is a viral infection characterized by a low-grade fever, swollen glands, inflamed eyes, and a fine, pink rash.
72

an abnormal enlargement of the spleen.

77
synthetic interferon
used in the treatment of multiple sclerosis, hepatitis C, and some cancers.
78
systemic reaction
also known as anaphylaxis or anaphylactic shock, is a severe response to an allergen.
79
toxoplasmosis
a disease caused by a parasite that is most commonly transmitted from pets to humans by contact with contaminated feces.

spread to humans by the bite of an infected mosquito.
