What are the symptoms of pork spore disease? How is it treated?

Pork sporangiasis is a zoonotic parasitic disease, the pathogen is meat sporangia, generally sac-like parasitism in pig muscles. Symptoms are not obvious when the onset of pork sporidium is mild, and symptoms such as lack of energy and diarrhea occur when the disease is severe. At present, there is no effective treatment and drug for pork sporangiasis, and it is recommended to pay attention to strengthening prevention.

　　First, the symptoms of pork sporangiasis

　　1. When the symptoms are not obvious in mild infection, when the parasitism of the insect body is serious, diarrhea, increased body temperature, weakness, and paralysis of the posterior body can be seen. Sick pigs have decreased appetite, increased body temperature, diarrhea, and even temporary paralysis of the hind limbs, muscle discoloration, watery appearance, small white spots on it, old calcified, and Mie's sac can be seen in myofibers.

　　2. The diagnosis of the disease is difficult before death, and the diagnosis can be confirmed according to the changes in autopsy and the discovery of Michael's sac.

　　Second, the transmission route of pork sporangiasis

　　The intermediate hosts of carniosporidium are reptiles, birds, rodents, etc., and the terminal hosts are carnivores and humans. The ultimate host of Porcine-Canine Meat Spore is a dog, which circulates infection between dogs and pigs, and is mildly or non-pathogenic to pigs. The terminal host of porcine-human carnivosporidium is a human, circulating infection between humans and pigs, and the pathogenicity of pigs is not obvious. The terminal host of porcine-cat meat spore is a cat, which circulates infection between cats and pigs, which is highly pathogenic to pigs. After the terminal host swallows the muscles of the intermediate host containing The Michaelis, the Melichovyst undergoes gamete reproduction in its small intestine to produce oocysts, which often rupture in the intestine and escape the sporangia, which are excreted with feces. After being swallowed by the intermediate host, the sporangia reach the organs through blood flow, and after one or more generations of fission reproduction, the resulting mesophiles invade the muscle fibers to form The Misac.

　　Third, the treatment of pork sporangiasis

　　There is currently no treatment or medication for the disease.

　　The worm is found in muscles throughout the body, but in smaller numbers, it can appear without restriction.

　　When there are many insects and muscle lesions, the entire meat corpse is used as industrial raw materials or destroyed, and those without lesions appear after high temperature treatment.

　　When more insect bodies are found in local muscles, the muscles should be treated with high temperatures and then appear, and other parts are not restricted.

　　4. Preventive measures for pork sporangiasis

　　1. Strengthen breeding management, do not feed dogs and cats with raw meat, and prohibit dogs and cats from touching pigs and feed.

　　2. Mainly in the slaughter, the organs and tissues with pork sporids are picked out and burned, so that pigs and carnivores have the opportunity to eat.

　　3. Strengthen the health inspection of meat, and when it is found that there are more insects and muscle lesions, the entire meat corpse is used for industrial use or destruction, and the pork without lesions can be used after cooking.
