How much temperature can be killed by hydatid? How to kill hydatid?

Echinococcosis is a disease caused by the larvae of Echinococcus echinococcosis parasitic in humans and animals, commonly known as echinococcosis. Echinococcosis mainly comes from animal feces. How much temperature can be killed by hydatid? How to kill hydatid? The high prevalence areas of echinococcosis in China are mainly concentrated in alpine meadow areas, cold climate, arid pastoral areas and semi-agricultural and semi-pastoral areas. It is more serious in Xinjiang, Qinghai, Gansu, Ningxia, Xizang, Inner Mongolia, Shaanxi, Hebei, Shanxi and northern Sichuan.

There are mainly two kinds of echinococcosis: cystic echinococcosis and alveolar echinococcosis, which are caused by human tissues and organs parasitized by the larvae of Echinococcus granulosus (Echinococcus granulosus) and the larvae of Echinococcus multilocularis (Echinococcus multilocularis) respectively. The worm is reddish and 10 to 50 centimeters long. The mature segment is 7 mm long and 2-3 mm wide. It is oval in shape and looks like a cucumber seed. Each mature segment contains two sets of male and female reproductive organs, which is seriously harmful to livestock and human health.

Physical disinfection of hydatid: 1) High pressure steam disinfection: usually 9. 0 KPA pressure and 121-12 °C temperature 10-5 minutes, can kill various types of hepatitis virus; use steamer cooking or household pressure cooker, wait 20 minutes after steam cover valve, can achieve disinfection effect and kill echinococcosis. 2) boiling disinfection: boiling at a temperature of 100 °C for one minute can make hepatitis B, C, D, E and A viruses lose their vitality and infectivity; boiling for more than 5-20 minutes can kill all types of hepatitis viruses. Kill echinococcosis.

This method is suitable for the disinfection of tableware, nursing utensils and cotton fabrics. As for plastic products, synthetic fibers and fur products are not suitable. Bromogeramine and chlorhexidine (chlorhexidine) are not sure that Dumifen, Lysu, carbolic acid, rice vinegar and smoked vinegar have no effect on hepatitis B virus. In addition, the leftovers of hepatitis patients had better be boiled and disinfected before being discarded.

Echinococcosis life habits

The life cycle of echinococcosis must depend on two mammalian hosts to complete its life cycle. It goes through three stages: egg, echinoid butterfly and adult.

Echinococcosis adults are parasitic in the small intestine of canines (such as dogs, wolves, wild dogs, jackals, etc.) and cats, and pregnant segments or eggs are excreted with feces. Echinococcus granulosus eggs are swallowed into eggs by hoofed intermediate hosts (such as sheep, cattle, pigs, horses, camels) to develop into Echinococcus granulosus, and Echinococcus multilocularis are swallowed into eggs by rodents and rabbits to develop into Echinococcus granulosus. Echinococcus spinosus develops in the liver, lungs and other organs. Human contact with the host results in the formation of space-occupying lesions in the liver, lungs and other organs. After being swallowed by the final host dog, Echinococcus granulosus develops into an adult in the dog's small intestine, while Echinococcus granulosus mainly circulates in livestock in the more developed areas of animal husbandry. Echinococcus granulosus has a variety of intermediate hosts, mainly hoofed livestock (for example, sheep, goats, pigs, camels, horses, cattle) Echinococcus multilocularis circulates mainly in wild animals such as rodents and rabbits, and its main intermediate hosts are pikas, Qinghai voles and so on.

Infection route of echinococcosis

There are some main sources of infection in the epidemic link of echinococcosis, while infected dogs, foxes, dogs, wolves and cats infected with echinococcosis Wolf and fox are the sources of infection of cystic echinococcosis (echinococcosis). (2) the way and mode of hydatid infection: echinococcosis is transmitted by eating eggs, and the intermediate hosts include human, hoofed animals, rodents and so on. The main route of infection is oral intake. Human infection is mainly caused by drinking water and diet. (3) people susceptible to echinococcosis: people of different races and genders are susceptible to echinococcosis. People engaged in animal husbandry production, hunting and fur processing are high-risk groups.

What are the main hazards of echinococcosis

The direct harm of echinococcosis to human body is mainly mechanical compression and toxin, and its harm degree is closely related to the parasitic site, size, quantity, nature and complications of hydatid cyst.

Patients with early echinococcosis have no obvious symptoms and signs, with the passage of time, hydatid cysts gradually increase and begin to squeeze surrounding tissues and organs and appear symptoms: hepatic echinococcosis often causes dull pain in the liver area, distension and discomfort, fullness of the upper abdomen, poor appetite, etc.; giant hepatic echinococcosis can raise the diaphragm and oppress the lungs, making it difficult to breathe. Pulmonary echinococcosis is often accompanied by dull pain or tingling in the chest; giant pulmonary echinococcosis can cause dry cough due to squeezing the bronchi, or chest tightness and shortness of breath due to compression of lung tissue. Other organs such as brain, kidney, heart and other echinococcosis, the consequences are more serious.

1. Hydatid infection: hydatid infection can form an abscess, systemic inflammatory reaction and fear of cold, fever and other toxic blood symptoms, often accompanied by jaundice, cough, anemia, emaciation and so on.

two。 Hydatid rupture: the main cause of rupture is external force compression, followed by local vibration, infection perforation and spontaneous rupture. ① breaks into the biliary tract: after hepatic echinococcosis breaks into the biliary tract, due to the influx of cystic fluid into the hepatic duct, it will cause severe biliary colic, chills and high fever, often secondary infection. If the daughter capsule or internal capsule fragments block the bile duct, it can be complicated with obstructive jaundice, often forming acute obstructive suppurative cholangitis.

3. Hematogenous metastasis: exfoliated tissues and fragments of protoscolex or alveolar echinococcosis can sneak into the blood circulation and occur echinococcosis in other organs, especially secondary pulmonary echinococcosis and cerebral echinococcosis metastatic by hepatic echinococcosis.

4. Portal hypertension: giant hepatic echinococcosis is often associated with portal hypertension, such as enlargement of liver and spleen, ascites, edema, abdominal varicose veins and failure, emaciation and so on.

In short, human echinococcosis causes serious damage to human health, brings extremely heavy pain to patients, at the same time seriously restricts the process of getting rid of poverty and becoming rich, and even causes poverty or return to poverty. Livestock echinococcosis will cause great losses to the regional economy because it hinders animal husbandry production, and the development of tourism in emerging areas will also be affected by the high prevalence of echinococcosis.
