How to prevent and cure porcine cysticercosis

After the single slaughter of pigs, there is a transparent capsule on the intestines, like blisters, ranging in size from soybeans to eggs, commonly known as "water bells". If examined carefully, you can see that there is a milky node inside, which is a parasite of domestic animals, which is called fine neck cysticercosis in veterinary medicine. When the dog swallowed the undead Cysticercus cercariae, it protruded the scolex on the mucous membrane of the dog's small intestine, attached to the intestinal wall, and gradually developed into an adult worm-vesicular tapeworm. The adult is composed of 250 to 300 segments, reaching a sexual maturity of 150 to 500 centimeters, reaching vesicular zone, and then begins to produce pregnant egg segments, which are excreted with their feces. Soon, the segments break and scatter the eggs. Pigs can be infected after eating feed contaminated by eggs or drinking water contaminated by eggs. The eggs are melted in the digestive tract of pigs, the embryo membrane is melted, six-hook cercariae are released, and the larvae drill into the blood vessels of the intestinal wall by protruding six hooks. As the blood circulates to the liver, and then migrates to the surface of the liver, some worms fall from the surface of the liver to the abdominal cavity and attach to the mesentery and omentum casserole. after about 3 months, they develop into infectious Cysticercus cercariae-"water bell". If people mistook it for immature fat refining and let children play, once it is broken, it will pollute the food, and people will cause infection to the human body after eating contaminated food by mistake.

(1) symptoms of illness

Most of the disease shows a chronic course, and there are no symptoms when the diseased pigs are parasitized by a small number of worms, while when a large number of parasites are parasitized, the clinical manifestations include elevated body temperature, loss of appetite, weight loss, system weakness, abdominal enlargement or peritonitis with icteric hepatitis.

(2) Prevention and control methods

1. To prevent and prevent this disease, we should strictly implement the veterinary health inspection procedures when slaughtering pigs and find that there is a "water bell". It should be destroyed or buried immediately after removal, and it is forbidden to eat it, not to abandon it arbitrarily, and not to give it to dogs. To prevent dogs from developing into Taenia saginata after eating, causing chain infection, it is best to prohibit dogs from entering the pigsty, and to ensure that feed and drinking water are not contaminated by the feces of sick dogs. Betel nut and pumpkin seeds can be used for regular deworming of dogs.

2. Treatment

(1) use 250 grams of tea to burn ash (white), 1 tablespoon each time, and take it internally with feed for 4 times.

(2) the praziquantel was mixed with sterilized liquid paraffin at 1:6. At the end of the study, the pigs were given 50 mg per kg body weight for 5 days, or 50 mg per kg body weight, twice by deep intramuscular injection, each time at an interval of one day.
