Starts with  
A
Are a type of antimicrobial drug used in the treatment and prevention of bacterial infections
Starts with  
B
Ubiquitous one-celled organisms, spherical, spiral, or rod-shaped and appearing singly or in chains, phylum of the kingdom Monera, various species of which are involved in fermentation, putrefaction, infectious diseases, or nitrogen fixation
Starts with  
C
The basic structural unit of all organisms
Starts with  
D
An abnormal condition of a part, organ, or system of an organism resulting from various causes, such as infection, inflammation, environmental factors, or genetic defect, and characterized by an identifiable group of signs, symptoms, or both.
Starts with  
E
Spreading rapidly and extensively by infection and affecting many individuals in an area or a population at the same time
Starts with  
F
Inlfuenza. Several infections that affect the respiratory or gastrointestinal tract and are caused by virus
Starts with  
G
A microorganism, especially a pathogen. Non-technical term for a disease causing microbe
Starts with  
H
A retrovirus of the genus Lentivirus that causes AIDS by infecting helper T cells of the immune system.
Starts with  
I
The invasion of bodily tissue by pathogenic microorganisms that proliferate, resulting in tissue injury that can progress to disease
Starts with  
J
Was an English physician and scientist who was the pioneer of smallpox vaccine, the world's first vaccine
Starts with  
K
Are a sub-group of T cells that kill cells that are infected with viruses (and other pathogens), or are otherwise damaged or dysfunctional
Starts with  
L
The network of vessels through which lymph drains from the tissues into the blood.
Starts with  
M
Any of various large, phagocytic white blood cells that develop from monocytes, are found in the spleen, liver, and other tissues, and have a variety of functions in the immune system including engulfing and destroying pathogens and dead cells, presenting antigens to activate lymphocytes, and releasing cytokines that mediate inflammation.
Starts with  
N
A membrane-bound organelle within a eukaryotic cell that contains most of the cell's genetic material. DNA transcription takes place in it
Starts with  
O
A differentiated structure within a cell, such as a mitochondrion, vacuole, or chloroplast, that performs a specific function
Starts with  
P
A contagious disease, caused by a virus, that mainly affects the nerve cells of the spinal cord and brain, often leading to muscle weakness and paralysis
Starts with  
Q
Recurring daily. Used especially of attacks of malaria.
Starts with  
R
A cell in the blood of vertebrates that transports oxygen and carbon dioxide to and from the tissues. In mammals, the red blood cell is disk-shaped and biconcave, contains hemoglobin, and lacks a nucleus. Also called erythrocyte
Starts with  
S
An abdominal organ involved in the production and removal of blood cells in most vertebrates and forming part of the immune system.
Starts with  
T
A lymphoid organ situated in the neck of vertebrates which produces T-lymphocytes for the immune system.
Contains  
U
An ultramicroscopic (20 to 300 nm in diameter), metabolically inert, infectious agent that replicates only within the cells of living hosts, mainly bacteria, plants, and animals: composed of an RNA or DNA core, a protein coat, and, in more complex types, a surrounding envelope
Starts with  
V
A preparation of a weakened or killed pathogen, such as a bacterium or virus, or of a portion of the pathogen's structure, that is administered to prevent or treat infection by the pathogen and that functions by stimulating the production of an immune response.
Starts with  
W
Any of various cells that in adult mammals are produced in bone marrow, have a nucleus but no hemoglobin, and function in the immune system by protecting against pathogens and aiding in tissue repair. White blood cells include neutrophils, eosinophils, basophils, lymphocytes, and monocytes, and they are found in blood, lymph, and certain tissues. Also called leukocyte
Contains  
X
An acute, highly infectious, often fatal disease caused by a poxvirus and characterized by high fever and aches with subsequent widespread eruption of pimples that blister, produce pus, and form pockmarks. Also called variola
Starts with  
Y
A custardlike food with a tart flavor, prepared from milk curdled by bacteria, especially Lactobacillus bulgaricus and Streptococcus thermophilus, and often sweetened or flavored.
Contains  
Z
To expel air forcibly from the mouth and nose in an explosive, spasmodic involuntary action resulting chiefly from irritation of the nasal mucous membrane.
