A girl in Zhongshan, Guangdong likes to eat raw fish and raw meat. The intestines are full of bugs. How does this bug grow in the body?

This 17-year-old girl was admitted to the hospital because of repeated abdominal pain and unexplained abdominal distension. There are many living things in her abdomen CT, and the doctor diagnosed many parasites in her stomach. Then how did she get infected? The girl said that she likes sashimi very much on weekdays and eats it once or twice a month. I also like to eat fresh food and sashimi. This time, the doctor judged that she had eaten unclean food and was infected with such a disease.

The most easily infected parasite of sashimi is Taenia solium. Generally parasitic by freshwater fish, it is transferred to the human body because of human consumption. Sushi, pickled fish with lemon juice and other foods may be infected with parasites if they are not handled properly. Doctors suggest that reducing the intake of fresh food and raw water is the best way to avoid infection.

At first, Taenia solium will follow the feces into the outside world. In the outside world, it will look for its first host, such as cyclops, develop protozoa in its blood cavity, and then leave the first host and enter the second host, such as frogs, snakes, birds and pigs. Cyclops are eaten by tadpoles, so they are parasitic on frogs, and they are adult sporozoites, which will parasitize frogs' legs for daily blood sucking. Humans are their ultimate hosts. People send adults into the intestine because they eat some unhygienic and parasitic sashimi by mistake, and they will multiply and grow in it and ovulate constantly.

At present, the survival period of sparganium in human body is very long, up to 12 years.

Every year, 50 million people around the world are infected with this parasite, and 50,000 people die from this parasite that lives in the brain. Schizophrenia can be parasitic in the mouth, brain, viscera, reproductive organs and eyes, and different positions correspond to different infection routes, especially because listening to folk remedies and sticking frog meat on the eyes can infect this eye parasite. Pay attention to hygiene and stay away from parasites.
