Anonymous users2024-01-24Ascaris lumbricoides Linnaeus (1758), abbreviated as roundworm, is one of the most common parasites in the human body. Adult worms live in the small intestine and can cause ascariasis. In addition, Toxocara canis (Ascaris canis) is a common intestinal parasite in dogs, and its larvae can migrate through the human body, causing visceral larva migrans (VLM).
Ascaris eggs are excreted in the feces, and there are two types of eggs: fertilized eggs and non-fertilized eggs, and only fertilized eggs can cleavage and develop.
Ascaris develop into rod-shaped larvae in about 10 days in 21 30, moist, oxygen-rich, shady soil. Once the skin is shed, it becomes an infectious egg with an infective larvae, at which point if swallowed, the egg shell is digested, and the larvae escape from the intestine. Then through the intestinal wall, into the lymph glands and mesenteric veins, through the liver, right heart, lungs, through the capillaries to the alveoli, and then through the trachea, larynx epiglottis, oral cavity, esophagus, stomach, back to the small intestine, the whole process is about 25 29 days, peeling off the skin 3 times, and then developing into an adult worm after more than 1 month.
After infection, symptoms such as fever, cough, loss of appetite or hunger, paroxysmal pain around the umbilicus, malnutrition, insomnia, teeth grinding, and sometimes serious complications can occur. For example, roundworms twisted into clusters can form roundworm intestinal obstruction, burrow into the biliary tract to form biliary ascariasis, and enter the appendix to cause appendiceciasis and intestinal puncture, which is very harmful to the human body. prevention of ascariasis, mainly to treat patients and eliminate the source of infection; do a good job in manure management; Pay attention to personal hygiene to prevent insect eggs from entering the population.
Ascaris can grow up to 20 cm in length in the human body, and when it reaches this length, it will emerge from any gap or hole in the human body (including the corner of the eye).
Commonly used anthelmintic drugs include mebendazole (Anlux), albendazole (intestinal worm clearing), levamisole (repellent ascaris), piperazine citrate (repellent ascarin, Liuyi pagoda sugar), see commonly used anthelmintic drugs for details. Since roundworms generally live in the human body for about a year, if reinfection can be avoided, ascariasis can "heal itself" in about a year.
