Excuse me, where do parasites get into the brain? is not from the stomach

Analysis: Hello, first of all, parasites can enter the stomach by a variety of routes, such as diet is not careful. 1 The eggs of some parasites will hatch into cysticerci in the duodenum and burrow into the intestinal wall, enter the systemic circulation and choroid through the intestinal membrane vein, and then enter the brain parenchyma subarachnoid space and ventricular system.

The parasite is able to circulate through the blood and body fluids1 to organs and brain tissue. Guidance: Hello, it is recommended to pay attention to washing hands before eating and after using the toilet.

Pay attention to personal hygiene and bathe frequently. Cook meat, seafood thoroughly. Drinking water should be boiled thoroughly.

Eradicate mosquitoes and other disease-transmitting insects. If you are infected with the parasite, seek medical attention promptly. Do not eat spicy hot, rice noodles and other foods.

I wish you good health.

Disease analysis: The occurrence of cerebral cyst is due to the following reasons: oral administration of pork tapeworm eggs, developed into cysticercia, through the digestive tract through the intestinal wall into the mesenteric venules, and then through the systemic circulation to the meninges, brain parenchyma and ventricles.

Guidance: The occurrence of cerebral cyst is due to the following reasons: oral administration of pork tapeworm eggs, which develop into cysticerci and penetrate the intestinal wall through the digestive tract into mesenteric venules, and then reach the meninges, brain parenchyma and ventricles through systemic circulation.

Analysis: Hello! Parasites can enter brain tissue in many ways, the most important of which is through the bloodstream. Guidance: If there is a parasite in the brain tissue, it is necessary to find out what the parasite is and treat the symptoms**.

The parasite enters the brain.

This is a cyst of the tapeworm, the adult can grow up to 2 to 4 meters, but it is mainly parasitic in the intestine, and the cyst can travel around with the bloodstream.

The above sentence is from the news given by the subject. This sentence may not be noticed by non-medical professionals, but it already contains two important points of knowledge in parasitology.

Tapeworms (extended to nematodes, which are more closely related) are mainly parasitic in the intestines.

The larval stage (cysts) of tapeworms and nematodes can travel around with the bloodstream. Larval migrans encyclopedia.

Nematodes and tapeworms alone may be difficult to understand, so let's explain them this way: nematodes mainly include roundworm-like nematodes (roundworms), Demodex intestinal nematodes (pinworms), duodenal hookworms, and American hookworms (hookworms). Tapeworms mainly include beef tapeworms, pork tapeworms, echinococcus granulosus and Diegong mansoni tapeworms, which rely mainly on cattle, pigs, dogs and frogs as intermediate hosts for transmission, respectively.

In other words, people who eat undercooked beef, pork, dog and frog meat have a high chance of changing the four parasitic diseases mentioned above.

So now suppose that we have eaten undercooked foods such as "rice pork" rice pork encyclopedia, which contain parasite larvae and their eggs. Then the larvae that are eaten are parasitic in the intestine and develop into adult worms to absorb nutrients, and when they grow to 2 or 4 meters, it will not have a big impact on the human body. However, the eggs hatch into larvae and migrate into the bloodstream.

As a little bug with ideals and ambitions, the first thing that comes to mind after eating and drinking enough is development - development must be in the gut to take place. So in the bloodstream, it burrows all over the body in order to reach the intestines. Very unlucky, some bugs lost their way and broke through the blood-brain barrier to the brain, and they could no longer grow into adults.

Of course, they are not willing to scatter and continue to rampage, ah, that picture is so beautiful that I dare not think about it

In addition to the above common nematodes and tapeworms, there are also worms that can penetrate the blood-brain barrier and enter the brain, as well as the "brain-eating worm", which can kill people in a few days, and can induce fetal malformations, control the mouse mind, and send it to the cat's mouth to complete the development process, and can make the woman become "open" (I am also drunk). of Toxoplasma gondii、Can't think of it and write a "and so on。

This maybe, generally not, positive**, if positive**, you can rest assured.

Analysis: Hello, this situation is mostly due to the infection of parasites and their eggs or larvae enter the brain through the bloodstream. For example, neurocysticercosis is a parasitic disease caused by the human being infected with the larvae of the tapeworm suis and invading the brain tissue.

Suggestions: If there is a brain parasitic disease, it should be actively carried out ** to avoid brain tissue damage and cerebral edema.

But don't panic too much, because only a few species can. The parasite's journey from the stomach to the brain can generally only be achieved through the vascular pathway. In other words, first of all, the adult or larvae of the parasite must be able to survive in the bloodstream as well as the egg.

The second is that the human body has a blood-brain barrier, which is equivalent to a filter, which will prevent some abnormal foreign bodies from entering the brain, and only some parasites that are tiny in size at a certain stage can enter the baby. Those that are too large will be treated as foreign bodies and cannot enter the bloodstream, those that are too small will be eaten up by phagocytes in the blood, and those that are not strong enough to break through the blood-brain barrier.

So in general, the parasites that can enter the brain from the stomach are very few.
