Cysticercosis, commonly known as swine cysticercosis, is a parasitic disease that is parasitic in the muscles of pigs by the larvae of the pig tapeworm, the porcine cysticercosis. Because the larvae have white sacs in the muscles, they are called porcinis, rice pork, or bean pork. It is one of the parasitic diseases of zoonotic diseases that are mainly controlled and is very serious.
1, let the pathogen and epidemic characteristics
The pathogen is the larvae of the band family and genus Tapeworm - the pig cysticercosis. Swine cysticercosis is a global distribution, now mostly seen in temperate and tropical regions of some countries, most of china has the occurrence of this disease, generally mostly sporadic, there are free-range pig habits, people without toilets in the area, the incidence of swine cysticercosis is higher, people eat raw pork or uncooked pork is easy to infect with pig bandworm disease.
2. Clinical symptoms and pathological changes
The general symptoms of pigs are not obvious, and when some organs are infected or affected, anemia, ema, growth retardation, failure and even death can be seen. Parasitism in the lungs and larynx, dyspnea, dysphagia, hoarseness; Parasitism in the eye, can cause visual impairment and even blindness; When parasitized in the brain, it causes symptoms of epilepsy leading to death. Severely infected pork is pale and moist, and cysticercosis can be found in some muscles, brain, eyes, sublingual tongue, etc., and the surrounding tissue cells are infiltrated and fibrous degenerated.
3. Diagnosis before death is more difficult
It can be judged according to the special symptoms of pigs in severe cases, such as protruding eyeballs, puffy eyelids, rough breathing, widening of the shoulder blades, narrowing of the buttocks, and grainy touch under the tongue, conjunctiva, medial femoral muscles, cheeks, etc. In addition, rapid and accurate diagnosis can be made using immunological methods, such as indirect hemagglutination carbon agglutination, intradermal allergic reactions, and cyclic precipitation tests.
4. The key measures to prevent the extinguishing of the disease are in prevention
Strict meat inspection system, it is strictly forbidden to market pork containing cysts, and pork containing cysts should be treated harmlessly. The inspection focuses on meat joint processing plants, slaughterhouses, urban and rural farmers' markets, so that there is a slaughter that must be inspected, and according to the inspection results, the cysticer parasitic pork is treated accordingly. Cysticercosis and calcified insects found in less than 3 within a 40 square centimeter area of the prescribed test site, frozen or salted after treatment; In 4 to 5, after high temperature treatment, it is listed; In 6 to 10 cases, for industrial use or destruction; After the insect body is removed, it can be used as a replication raw material; More than 11 of them shall be used for industrial use or destroyed
