Parasites in the brain Vs cysticercosis
Parasites in the brain Vs cysticercosis explanation :
Why Do Parasites Live In The Brain?
Different parasites choose to make their home in different places in the body.The brain is filled with oxygen and nutrients, and it also has structures in place that prevent the immune system from attacking parasites in the initial stages of infection. This makes for an inviting home for brain parasites or some called worms in the brain.
How Do Parasites Get Into The Brain?
This barrier between the blood and the fluid in the brain is comprised of cells that form a tight seal around the blood vessels that bring nutrients to and from the brain. This makes it difficult (but not impossible) for parasites and other toxins to enter the brain.
Which Parasites Can Infect The Brain?
- Taenia solium
- Naegleria fowleri
What is cysticercosis?
Cysticercosis is an infection caused by the pork tapeworm, Taenia solium. Infection occurs when the tapeworm larvae enter the body and form cysticerci . When cysticerci are found in the brain, the condition is called neurocysticercosis.
Infection is found most often in rural, developing countries with poor hygiene where pigs are allowed to roam freely and eat human feces. This allows the tapeworm infection to be completed and the cycle to continue. Infection can occur, though rarely, if you have never traveled outside of the United States. Taeniasis and cysticercosis are very rare in Muslim countries where eating pork is forbidden.
How can I get cysticercosis?
You can get cysticercosis by accidentally swallowing pork tapeworm eggs. Tapeworm eggs are passed in the bowel movement of a person who is infected. These tapeworm eggs are spread through food, water, or surfaces contaminated with feces. This can happen by drinking contaminated water or food, or by putting contaminated fingers to your mouth. A person who has a tapeworm infection can reinfect themselves (autoinfection). Once inside the stomach, the tapeworm egg hatches, penetrates the intestine, travels through the bloodstream and may develop into cysticerci in the muscles, brain, or eyes.
