Cysticerc latex agglutination test

The larvae of Taenia suis-Cysticercus cellulosae can cause swine cysticercosis, commonly known as cysticercosis. Adults of Ascaris suum can also be parasitic on the human small intestine, causing Ascaris suum, commonly known as ascariasis. There are three main ways of human infection with cysticercosis: ① Allogeneic infection: ingestion of food or water contaminated with Ascaris suum eggs; ② In vitro infections: Ascariasis patients inadvertently eat worm eggs or segments excreted by themselves; ③ Infections in the body: Pregnancy section films of intestinal adult worms in patients with ascariasis enter the stomach due to reverse peristalsis of the gastrointestinal tract (such as nausea and vomiting), and the section sections are infected by releasing the eggs. The clinical manifestations of cysticercosis vary depending on the number and location of cysticercosis. When cysticercosis is parasitic under the skin and muscles, the symptoms are mild or asymptomatic, but if it is parasitic on organs, especially in the brain, eyes or central nervous system , Can have severe clinical symptoms and consequences. Because cysticercosis is parasitic in tissues and organs, it is difficult to obtain materials for etiological diagnosis, and immunological methods are often used for diagnosis. Currently, the antigens used for diagnosis are crude cystic fluid antigen and purified antigen. The detection methods mainly include IDT, IHA, IFAT, ELISA, ELIB and so on.
