Pomeranian (detail introduction)
The disease is caused by the body that parasitizes the body in the small intestine and the stomach. This kind of disease is mainly harmful to the puppies that are just born, which has a great impact on the growth and development of puppies, which can cause dog death in severe cases.
The history of the pathogen and its life
The canine tapeworm is pale yellow, with 3 lips at the head and a narrow neck film on the side. The characteristic of dog tapeworm is that there is a small stomach in connection between the esophagus and the intestinal tube. The male is 50-110 mm long, and the end is bent at the end of the female. The color of the lion tapeworm (lion bowl) is similar to that of the canine tapeworm, but there is no small stomach: 35-70 mm of the male, 30-100 mm in female. Dog tapeworm eggs are discharged from the body with feces, and developed into infectious worm eggs under appropriate conditions. After the dog within March, a dog swallows the infectious insect eggs, and the larvae hatch in the intestine, the larvae drilled into the intestinal wall, passed the lymphatic system to the intestinal membrane lymph nodes, then reached the liver through the blood flow, and then reached the lungs with the blood flow. Affular, fine-tubing, bronchials, and then throat were swallowed into the stomach, and the small intestine was further developed into adults. The whole process was 4-5 weeks. After the older dog swallowed the infectious insect eggs, the larvae reached the tissue and organs of the body with the blood flow, forming a bag, and the larvae kept vitality, but did not develop further; The fetal liver is moved through the placenta to cause intra -fetal infection. After the fetus was born, the larvae moved to the lungs, and then moved to the gastrointestinal tract to develop into a adult. Mature dogs and worms have appeared 23-40 days after the birth of the dog. Newborn dogs can cause infection by sucking colostrum; larvae developed directly into adults in the small intestine after infection. Under the appropriate conditions of the outside world, the lion tapeworm eggs develop into the infectious insect eggs. After being swallowed by the dog, the larvae are relaxed in the small intestine, and then the intestinal wall develops into the intestinal wall and returns the intestinal cavity. Essence
