Prevention and control of porcine clonorchiasis
1. Clonorchiasis ginger.
⑴ treatment. The following drugs can be used to disinfect insects:
① thiobenzene dichlorophenol. 60mg to 70mg per kg of body weight, mixed with a small amount of concentrate, safe and effective.
② nitrothiocyanamide. 3mg to 6mg per kilogram of body weight, once mixed and fed.
③ praziquantel. 5 mg per kilogram of body weight, good deworming effect.
④ trichlorfon. 100 mg per kilogram of body weight, the total amount of pigs does not exceed 8 g. Oral administration can not only achieve better results, but also dispel Ascaris lumbricoides and Trichuris. It is generally believed that organophosphorus preparations such as trichlorfon are only effective against nematodes. The reason why trichlorfon can dispel ginger fluke may be that trichlorfon can make the intestine wriggle violently, so that ginger fluke can not adhere to the intestinal wall and be excreted.
⑵ prevention.
The feces of pigs with ① disease should accumulate and ferment, kill insect eggs and cut off the source of infection.
Regular deworming of ② is a very important preventive measure. Because the infection season is about 2 months after the local temperature reaches more than 270.32 ℃ every year. At this time, if the pig is infected, it will take another 3 months before the larva can develop into an adult, and this time (late autumn) is the most appropriate.
③ can choose 0.1% quicklime, 2% 10 mg / L copper sulfate and 0.01% tea cake to kill snails in ponds where aquatic forage is planted.
two。 Clonorchiasis sinensis.
⑴ treatment. The following drugs can be used to disinfect insects:
① praziquantel. It can be used as the first choice of drug. The dose is 2mg / kg body weight, once orally taken.
② albendazole. 30 mg per kilogram of body weight, once a day for several days.
③ HCP. 20 mg per kg body weight, orally, once a day for 2-3 days.
④ Haitao Lin. 50mg / kg body weight, mixed with feed, once a day, 5 days as a course of treatment.
⑵ prevention.
Pigs, cats and dogs in endemic areas are regularly checked and dewormed by ①.
② forbids feeding animals with raw or semi-raw fish and shrimp in epidemic areas.
③ manages the droppings of pigs, dogs and other animals, removes and accumulates fermentation in time to prevent feces from polluting ponds, and forbids building toilets or pig sheds beside fish ponds.
④ eliminated the first intermediate host freshwater snails.

Paragonimiasis in pigs
1. The pathogen paragonimiasis is caused by the parasitism of paragonimiasis in the lungs of pigs. The trematodes are dark brown, oval, fleshy trematodes, 8-16 mm long, 4-8 mm wide and 2.5 mm thick. The adults are parasitic in the lung tissue of pigs. after the eggs are produced, they cough up with sputum, swallow in the mouth and excreted out of the body with feces. Under appropriate conditions, the cercariae escape from the egg and enter the first intermediate host (freshwater snail), where they develop into cercariae, which leave the snail body and enter the second intermediate host.
