Coccus
Coccus A bacterial cell which has the shape of a sphere. Coccus enters into the name of a number of bacteria. For example, enterococcus, meningococcus, pneumococcus, staphylococcus, and streptococcus.
RELATED TERMS--------------------------------------
Bacterial
Of or pertaining to bacteria. For example, a bacterial lung infection.
Cell
Fundamental structural unit of all life. The cell consists primarily of an outer plasma membrane, which separates it from the environment; the genetic material (DNA), which encodes heritable information for the maintainance of life; and the cytoplasm, a heterogeneous assemblage of ions, molecules, and fluid.

Bacteria
Single-celled microorganisms which can exist either as independent (free-living) organisms or as parasites (dependent upon another organism for life).
Enterococcus
Bacteria normally found in the feces of people and many animals. Two types of enterococci -- Enterococcus faecalis and Enterococcus faecium --occasionally cause human disease, most commonly urinary tract infections and wound infections. Other infections, including those of the blood stream (bacteraemia), heart valves (endocarditis) and the brain (meningitis) can occur in severely ill patients in hospitals. Enterococci also often colonize open wounds and skin ulcers.
Staphylococcus
Spherical gram-positive parasitic bacteria that tend to form irregular colonies; some cause boils or septicemia or infections.
Streptococcus
A type of bacterium that may infect tonsils. Infection with this bacterium, if not treated with penicillin or other appropriate antibiotic, can lead to rheumatic fever.
SIMILAR TERMS--------------------------------------
Cocci
Bacteria which are spherically shaped.
Coccidioidomycosis (CM)
A disease due to a fungus called Coccidioides immitis. About 40% of people infected with this fungus develop symptoms. Most often they have an influenza-like illness with fever, cough, headaches, rash, and myalgias (muscle pains). Of those people with symptoms, 8% have severe lung disease requiring hospitalization and 7% develop disseminated infection (throughout the body).
Coccobacillus
A short, thick bacterial rod of the shape of an oval or slightly elongated coccus.
Coccydynia
Pain in the coccyx (the tailbone). The coccyx is the small bone at the bottom of the spine very near the anus. The coccyx is made up of 3-5 rudimentary vertebrae and is the lowest part of the spinal column.
Coccygeal
Referring to the coccyx, the small tail-like bone at the bottom of the spine, that is made up of 3-5 (average of 4) rudimentary vertebrae. There is a coccygeal nerve that originates in the spinal cord and emerges at the level of the coccyx.
Coccygeal vertebrae
The coccyx, the small tail-like bone at the bottom of the spine near the anus, is made up of 3-5 (average of 4) rudimentary vertebrae.
Coccyx
The tailbone.
Coccyx bone
The small tail-like bone at the bottom of the spine very near to the anus. The coccyx is made up of 3-5 rudimentary vertebrae. It is the lowest part of the spinal column.
PREVIOUS AND NEXT TERMS--------------------------------------
Coarctation
A narrowing, a stricture, a constriction. Although the best known coarctation is of the aorta, any artery can have a coarctation. The word "coarctation" comes from the Latin "coartare" meaning :to press together." The sides of the vessel at the point of a coarctation appear pressed together.
Coarctation of the aorta
A congenital constriction of the aorta, impeding the flow of blood below the level of the constriction and increasing blood pressure above the constriction. Symptoms may not be evident at birth but may develop as soon as the first week after birth with congestive heart failure or high blood pressure that call for early surgery. The surgery otherwise can be delayed. The outlook after surgery is favorable. Some cases have been treated by balloon angioplasty.
Coated stent
Also known as a medicated stent. A tiny cage coated with a drug to prop open an artery and prevent it from closing again.
