    Candida infection of the skin

    This microscopic film shows a fluorescent stain of Candida. Candida is a yeast (fungus) that causes mild disease, but in immunocompromised individuals it may cause life-threatening illness. (Image courtesy of the Centers for Disease Control and Prevention.)

    Cutaneous candidiasis is infection of the skin with candida fungus.

    CMV - pneumonia

    Cytomegalovirus is a large herpes-type virus commonly found in humans that can cause serious infections in people with impaired immunity. CMV pneumonia is treated with antiviral medications, which may stop the replication of the virus but will not destroy it.

    Cytomegalovirus (CMV) pneumonia is an infection of the lungs that can occur in people who have a suppressed immune system. See also:

    CMV serology test

    Blood is drawn from a vein (venipuncture), usually from the inside of the elbow or the back of the hand. A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. Preparation may vary depending on the specific test.

    The CMV serology test determines the presence of to a virus called cytomegalovirus (CMV) in the blood.

    Coccidioides complement fixation

    Blood is drawn from a vein (venipuncture), usually from the inside of the elbow or the back of the hand. A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. Preparation may vary depending on the specific test.

    Coccidioides complement fixation is a blood test that looks for to the fungus Coccidioides immitis. This fungus causes the disease .

    Coccidioides precipitin

    Blood is drawn from a vein (venipuncture), usually from the inside of the elbow or the back of the hand. A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. Preparation may vary depending on the specific test.

    Coccidioides precipitin is a blood test that looks for infections due to a fungus called Coccidioides immitis, which causes the disease .

    Cryptococcosis

    These are Cryptococcus skin lesions.  Cryptococcus is a yeast (type of fungus) that seldom causes infection, but is considered opportunistic (it affects people with weakened immune systems).  Cryptococcus is one of the more common life-threatening fungal infections in AIDS patients.

    Cryptococcosis is infection with Cryptococcus neoformans fungus.

    Cryptosporidium enteritis

    Cryptosporidium is a protozoan parasite found in contaminated water.  It has been increasingly recognized as the cause of outbreaks of diarrhea when water supplies become contaminated.  In normal individuals, it is a self-limited disease.  Among immunocompromised individuals with AIDS, cryptosporidium can cause severe diarrheal disease, gallbladder disease (cholecystitis), and inflammation of the pancreas (pancreatitis).

    Cryptosporidium enteritis is an infection of the small intestine with the parasite Cryptosporidium that causes diarrhea.

    CSF coccidioides complement fixation

    Blood is drawn from a vein (venipuncture), usually from the inside of the elbow or the back of the hand. A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. Preparation may vary depending on the specific test.

    CSF coccidioides complement fixation is a test that check for infection due to the fungus Coccidioides immitis in the cerebrospinal (CSF) fluid. This is the fluid surrounding the brain and spine.

    Cytomegalovirus retinitis

    The eye is the organ of sight, a nearly spherical hollow globe filled with fluids (humors). The outer layer or tunic (sclera, or white, and cornea) is fibrous and protective. The middle tunic layer (choroid, ciliary body and the iris) is vascular. The innermost layer (the retina) is nervous or sensory. The fluids in the eye are divided by the lens into the vitreous humor (behind the lens) and the aqueous humor (in front of the lens). The lens itself is flexible and suspended by ligaments which allow it to change shape to focus light on the retina, which is composed of sensory neurons.

    Cytomegalovirus (CMV) retinitis is a viral inflammation of the retina of the eye.
