believes that many older people are no strangers to parasites, such as roundworms. Roundworms mainly live, grow, and ovulate in the gastrointestinal tract until death or excretion with feces. Except for individual cases, such as severe pain caused by drilling into the biliary tract, and intestinal obstruction caused by too many insects, most of the time there are no serious consequences. However, there is another type of parasite, which is very harmful, such as Schizophyllum. After being eaten into the gastrointestinal tract, they can enter the bloodstream and reach all parts of the body with the blood, and often settle in the brain (brain blood vessels are many and thin), eyes and other parts. Not only does it form local masses, it also causes abnormal power generation in the brain, leading to epilepsy-like seizures, stubborn headaches, and unconsciousness.

　　According to the New Express on May 11th, Guangdong Yunfu girl Xiao Pei was infected with parasites in her brain by eating wild snakes and frogs many times. In the past year, she suffered from headaches and then caused epilepsy. It was not until recently that Guangzhou Pearl River Hospital performed a craniotomy for it and took out a live worm that had grown to a few centimeters before Xiao Pei''s symptoms disappeared.

　　 16-year-old Xiao Pei is a student of a school in Yunfu. He is lively and beautiful, playing small has always been healthy. But since last year, she felt that her head was sometimes painful, and her memory had declined, thinking that she was tired and did not care too much. But one day in April this year, she suddenly fainted for no reason, accompanied by convulsions in her limbs. After the treatment in the local hospital was not good, the family quickly sent her to the neurosurgery department of the Pearl River Hospital.

　　After the instrument inspection, a lesion was found in the frontal lobe of Xiaopei''s right brain-it may be a parasitic granuloma. The hospital underwent craniotomy under general anesthesia for Xiao Pei. During the operation, I saw an abnormal tissue in the middle frontal gyrus next to the midline of the right side of the brain of Xiaopei, which was tougher than the normal brain tissue and rich in blood flow. After the incision, there was a milky white cord-like bug, which violently twisted after electrocautery. After being completely taken out, it was found that the worms were several centimeters long, and were live larvae of Schizospora, which could swim in normal saline. The twisted head looked like a cobra, which looked shocking.

　　After the operation, Xiao Pei recovered quickly. There was no more headache and dizziness, no functional and sensory disturbances, and no epilepsy. The pathological examination report of the lesion tissue removed during the operation confirmed that the mass in Xiao Pei''s brain was Schizophyllum, and there were a large number of eggs in the intestinal cavity of the insect body. It is reported that Xiao Pei has eaten wild animals such as frogs and snakes many times, and still eats snake gall. Therefore, Xiao Pei may have eaten undercooked frogs or snakes, causing the parasites to get sick in the brain.

　　Cerocteris is scientifically known as Schizophyllum mansoni. Its adult worms are parasitic in the intestines of various animals such as cats and dogs. Its eggs are excreted with feces and larvae are hatched in water. The larvae enter frogs, snakes and other animals and develop into protocercaria. When a person eats uncooked water containing eggs or food containing protocercaria, the eggs are first adsorbed on the intestinal wall of the person, and then hatched into larvae, which then circulate through the blood. The survival time of Schizospora in the human body is 5-20 years.

　　Cleft cercariae are just one of the parasites that can enter the blood circulation and reach all parts of the body tissues, as well as a variety of parasites. It can enter the human body with freshwater fish, shellfish, livestock meat, poultry meat and other foods, and cause serious harm. In general, parasites and their eggs are difficult to withstand boiling at 100°C, as long as they are cooked and cooked thoroughly, they can all be killed.

　　Eating completely raw freshwater fish, shellfish, frogs, snakes, livestock meat, poultry, and drinking raw water (especially with contaminated dirty water) are of course the most dangerous, but this kind of The situation is not the most common. The most common situation is that although these foods have also been cooked, the heating time is too short, or the meat pieces are too large (the inside is not cooked), and they cannot completely kill the parasites, especially the eggs. Therefore, when cooking these foods, be sure to fully heat them and cook them thoroughly.
