Parasitic Diseases Causing Encephalitis Signs Of Awareness And Prevention

Parasitical Worms.com Illness caused by the nematode of Angiostrongylus cantonensis parasitizes and causes disease in the meninges, invasion of the brain can lead to death. Commonly called Meningitis - brain caused by Angiostrongylus cantonensis.
The causative agent of nematode Angiostrongylus
Adult worms live in the pulmonary artery of mice, worm eggs are laid in the blood, to the alveolar walls will form embryos within 6 days. The larvae hatch out along the bronchi, are swallowed by the rat in the gastrointestinal tract and out in the stool

.
The larvae can live for days in water, but die quickly when they are dry. It is swallowed by snails living on land or snails living on land, it can actively crawl through the snail's skin to enter the body.
The most common type of snail to be infected with the parasite is Achatina fulica In the muscles of snails, the worm develops to stage III larvae as the stage of infection Shrimp, crabs or plate discs can swallow snails and worm infections.
When mice swallow snails, the larvae follow the bloodstream to the brain and quickly become young worms (after 7 hours).



. It stays here for about 2 weeks, then follows the blood flow to the lungs and matures at the pulmonary artery.
When people eat snails, raw vegetables (with worm larvae released when snails die), shrimp, crabs or leeches, the larvae will follow the bloodstream to the brain and brain membranes, causing inflammation.
Epidemiology of meningococcal parasite
Parasites are found in the Far East, Southeast Asia, Australia, some Pacific Islands (Tahiti, New Caledonie, Hawaii .. ), Cuba, Reunion, Côte d'Ivoire, Malaysia, Thailand, China, Australia The disease is found in both North and South Vietnam.

Pictures of nematode worms Angiostrongylus cause brain damage
Sometimes, patients with additional nerve palsy VII; visual acuity, paresthésie, paralysis or loss of tendon reflex The patient may die, but this is unlikely.
Diagnosis of parasitic encephalitis
The cerebrospinal fluid in the brain, sometimes opaque, aseptic, albumin increases, 400-500 cells / mm3 of which 40-50% is calculated. Very rarely see young worms in the cerebrospinal fluid.
Endodontic reaction with Angiostrongylus antigen may be helpful in many cases.
Treatment of parasitic encephalitis
Use of analgesics, aspirate to extract cerebrospinal fluid to reduce pressure; corticosteroid anti-inflammatory drugs to limit the inflammatory response ..

Prevention of parasitic encephalitis
- Do not eat snails, freshwater shrimp, ground crabs, uncooked frogs, do not eat potentially contaminated vegetables
- Wash vegetables thoroughly under running water if eating river, washing hands before eating.
