Building Immunity & Reducing Infections Flashcards
the total composition of bacteria, fungi, viruses, and other microorganisms that inhabit a human body
human microbiome
a disease-causing organism
pathogen
transplanting fecal material from a healthy donor to the colon of an unwell person to create a healthful change in the patient’s intestinal microbiome
fecal microbiota transplantation
an infectious disease that is usually transmitted from person to person
communicable disease
specific cause of disease
etiology
a disease of red blood cells that produces fever, anemia, and death
malaria
the carrier of infectious organisms from animals to people or from person to person
vector
a chemical substance that carries genetic information in all cells of all organisms
deoxyribonucleic acid
an antibiotic produced by mold and capable of curing many bacterial infections
penicillin
specialized cells that destroy and eliminate foreign particles and microorganisms from the body
macrophages
white blood cells that fight infections
leukocytes
microscopic hairs in the lining of the bronchial tubes
cilia
a serious, difficult-to-diagnose infectious disease caused by bacteria deposited by ticks when they bite
Lyme disease
an infectious disease caused by the Epstein-Barr virus, common among college-age adults
mononucleosis
open sores in the stomach from infection by the bacterium H. pylori
gastric ulcers
serious disease of the liver caused by hepatitis virus A, B. C, D, or E also caused by chemicals and alcohol
hepatitis
infections that newly appear, or re-emerge, within a vulnerable population of people or known infections that are suddenly spreading rapidly
emerging infectious diseases
proteins that recognize and inactivate viruses, bacteria, and other organisms and toxic substances that enter the body
antibodies
an interacting system of organs and cells that protect the body from infectious organisms and harmful substances
immune system
nodules spaces along the lymphatic vessels that trap infectious organisms or foreign particles
lymph nodes
a system of vessels in the body that trap foreign organisms and particles; the immune system is part of the lymphatic system
lymphatic system
cells of the immune system that attack foreign organisms that infect the body
T cells
foreign proteins on infectious organisms that stimulate an antibody response
antigens
cells of the immune system that produce antibodies
B cells
small molecules that coordinate the activities of B cells and T cells
cytokines
