尾蚴为卵圆形、乳白色、半透明的泡，头节凹陷在泡内，可见有小钩及吸盘。此种具尾蚴的肉俗称为米粒肉或豆肉。这种猪肉被人吃了后，如果尾蚴未被杀死，在12指肠中其头节自内翻出，借小钩及吸盘附着于肠壁上，经2～3个月后发育成熟。成虫寿命较长，据称有的可活25年以上。此外，人误食猪带绦虫虫卵，也可在肌肉、皮下、脑、眼等部位发育成尾蚴。其感染的方式有：经口误食被虫卵污染的食物、水及蔬菜等，或已有该虫寄生，经被污染的手传入口中，或由于肠之逆蠕动（恶心呕吐）将脱落的孕卵节片返入胃中，其情形与食入大量虫卵一样。由此可知．人不仅是猪带绦虫的终寄主也可为其中间寄主。猪带绦虫病可引起患者消化不良、腹痛、腹泻、失眠、乏力、头痛，儿童可影响发育。猪尾蚴如寄生在人脑的部位，可引起癫痛、阵发性昏迷、呕吐、循环与呼吸紊乱；寄生在肌肉与皮下组织，可出现局部肌肉酸痛或麻木；寄生在眼的任何部位可引起视力障碍，甚至失明。此虫为世界性分布，但感染率不高，我国也有分布。猪带绦虫病在中国广泛分布，各地均有散发病例在东北与华东较牛带绦虫病多见，其比例为8∶1与7.1∶1，感染率由不足1%到15.2%。在云南、河南、黑龙江、吉林广西壮族自治区等地均有地方性流行。传染源感染猪带绦虫成虫的人是本病的传染源在中国农村猪仍以分散饲养为主猪常在圈外活动觅食，故误吞入人粪中猪带绦虫节片或虫卵机会较多。
The cercariae are ovoid, milky white and semitransparent vesicles. The head section is sunken in the vesicles. Small hooks and suckers are visible. This kind of tail meat is commonly known as rice meat or beans. After this kind of pork is eaten by people, if the cercariae are not killed, the head section of the 12-fin intestine is turned upside down and attached to the wall of the intestine by small hooks and suction cups. It matures after 2 to 3 months. Adults live longer, and some are said to live for more than 25 years. In addition, people who eat eggs of tapeworm eggs by mistake may also develop tail lice in muscles, subcutaneous tissues, brains, and eyes. The methods of infection include: Foods, water, and vegetables contaminated with eggs by oral ingestion, or parasitization of the insects, passing through contaminated handpieces, or falling off due to adverse peristalsis of the intestines (nausea and vomiting) The gestational egg section is returned to the stomach in the same way as a large number of eggs. This shows that. People are not only the final host of a tapeworm but also their intermediate host. Swine tapeworm disease can cause dyspepsia, abdominal pain, diarrhea, insomnia, fatigue, headaches, and children can affect development. Pigtails, such as parasites in the human brain, can cause epilepsy, paroxysmal coma, vomiting, circulatory and respiratory disorders; parasitism in muscle and subcutaneous tissue, can occur in local muscle aches or numbness; parasitic in any part of the eye can cause Visually impaired, even blind. This worm is distributed worldwide, but the infection rate is not high and China is also distributed. Swine tsutsugamushi disease is widely distributed in China. There are sporadic cases in the northeast and east China. The ratio is 8:1 and 7.1:1, and the infection rate ranges from less than 1% to 15.2%. In Yunnan, Henan, Heilongjiang, Jilin, Guangxi Zhuang Autonomous Region and other places are endemic. Sources of infection from pigs infected with tapeworm adults are the source of this disease. In rural China, pigs are still distributed as the main pigs often foraging activities outside the ring, so mistaken swallowing pigs with tapeworm or eggs More.
