An infection caused by the pork tapeworm, Taenia solium. Infection occurs when the tapeworm larvae enter the body and form cysts called cysticerci. When cysticerci are found in the brain, the condition is called neurocysticercosis. Cysticercosis is contracted by accidentally swallowing pork tapeworm eggs. Tapeworm eggs are passed in the bowel movement of a person who is infected. When the tapeworm eggs are inside the stomach, they hatch, penetrate the intestine, travel through the bloodstream, and may develop into cysticerci in the muscles, brain, or eyes. Infection is found most often in rural, developing countries where hygiene is poor and pigs are allowed to roam freely and eat human feces. Cysticercosis is not spread from person to person. However, a person who is infected with the intestinal tapeworm stage of the infection (T. solium) sheds tapeworm eggs in bowel movements. Tapeworm eggs that are accidentally swallowed by another person can cause infection.
Cysticercus: The larval form of any of the Taenia tapeworms. The plural is cysticerci. Infection with cysticerci is referred to as cysticercosis.
Cystine: An amino acid that is particularly notable because it is the least soluble of all of the naturally occurring amino acids and because it precipitates out of solution in the genetic disease cystinuria to form stones in the urinary tract. Cystine is the chief sulfur-containing compound in protein. Cystine is generated by the union […]
- Cystine kidney stones
Cystine kidney stones: Cystine kidney stones are due to cystinuria, an inherited (genetic) disorder of the transport of an amino acid (a building block of protein) called cystine that results in an excess of cystine in the urine (cystinuria) and the formation of cystine stones. Cystinuria is the most common defect in the transport of […]
- Cystine transport disease
Cystine transport disease: Commonly known as cystinuria, this is an inherited (genetic) disorder of the transport of an amino acid (a building block of protein) called cystine resulting in an excess of cystine in the urine (cystinuria) and the formation of cystine stones. Cystinuria is the most common defect in the transport of an amino […]
Cystinosis: A genetic disease characterized by the widespread deposition of the amino acid cystine in cells due to a defect in cystine transport. (Cystine normally forms after protein degradation and is transported from structures called lysosomes into the cytoplasm. In cystinosis, cystine accumulates in the lysoosmes and eventually forms crystals throughout the body. Cystinosis is […]
