Toxoplasma gondii, also known as three corpses, three Peng, three corpses, three corpses, is an intracellular parasite. Can cause people's immunity to decline, suffering from a variety of diseases. So how does toxoplasmosis spread in life? What are the symptoms? How to prevent infection?

How does Toxoplasma gondii spread in life?

1. People can also be transmitted to each other, most people are Toxoplasma gondii carriers, the formation of immunity, after being infected is very difficult to appear the symptoms of the first infection.

Urine of patients with Toxoplasma gondii, saliva, tears, snot, with Toxoplasma gondii cysts. The sneeze of a patient with acute attack can be a source of infection of droplets. In women with toxoplasmosis, Toxoplasma gondii activity is the strongest during menstruation, and the menstrual blood excreted by women often contains a large number of Toxoplasma gondii cysts, which is not a small source of infection and should never be ignored. In addition, Toxoplasma gondii cysts are also found in the semen of men with toxoplasmosis, which can be transmitted to each other through sex.

People eat meat from infected animals, which is the main cause of infection.

two。 Mechanical carrying of infected livestock, poultry, insects, etc.

3. Food infection:

(1) Food made from infected animals, such as fish, meat products, sausages, ham sausages, canned meat.

(2) Food produced by infected animals, such as eggs and milk.

(3) or these processed by-products are also contagious, such as dairy products, cream products, egg products, cakes, all kinds of biscuits, snacks and frozen snacks can sometimes become sources of infection.

(4) infected insects, birds and food contaminated by "mechanically carrying germs", such as vegetables and fruits.

(5) all foods that do not meet the hygiene standards may transmit toxoplasmosis.

What are the symptoms of toxoplasmosis?

1. Most of ocular toxoplasmosis is congenital and acquired may be caused by the activity of congenital latent lesions. Clinically, there are blurred vision, blind spots, fear of light, pain, tears, loss of central vision and so on. After the inflammation subsided, the vision was improved, but it was often not fully recovered. There may be vitreous opacity.

two。 The clinical manifestations of congenital toxoplasmosis are different. Most babies can be asymptomatic at birth, and some of them develop retinal choroiditis, strabismus, blindness, epilepsy, psychomotor or mental retardation a few months or years after birth. Patients with symptoms at birth have the following different combinations of clinical manifestations: retinal choroiditis; hydrocephalus or small and without malformation or anencephaly, intracranial calcification, with spondylolysis, meningocele, rabbit cleft lip and palate; absence of adrenal gland, double polycystic kidney; conjoined teratology; convulsions, psychomotor disorders; lymphadenomegaly, hepatosplenomegaly, fever, jaundice, skin rash, etc.

3. Most recessive infections, when suffering from malignant tumors, organ transplantation, long-term iatrogenic immune damage such as immunosuppressants, radiotherapy, cytotoxic agents, or congenital and acquired immunodeficiency, such as AIDS patients and pregnant women, can turn the state of recessive infection into acute severe disease and worsen the original disease. According to the United States Centers for Disease Control (CDC), there are 508 cases of Toxoplasma gondii encephalitis among 14510 AIDS patients, and most of them die within 2 to 8 months. Other data showed that among the 81 patients with Toxoplasma gondii, there were 32 cases of Hodgkin's disease, 9 cases of lymphosarcoma and 15 cases of leukemia.

How to prevent Toxoplasma infection?

1. Meat needs to be fully cooked and the raw and cooked case boards should be separated to avoid secondary pollution. The possibility of infection of raw meat is far greater than that of infection through cat dung. Pay attention to dietary hygiene.

2. If you have a cat at home, feed cooked food as much as possible. As the cats go out foraging for food, it increases the possibility of infection, so try not to let them go out to look for food.

3. Deal with cat feces in time every day, because the oocysts of Toxoplasma gondii usually need to develop in an environment of suitable temperature and humidity for 2 to 4 days before they become infectious, so clearing cat feces in time every day can reduce the probability of infection. wash hands carefully after contact with animal feces.

4. Pregnant women should avoid contact with cats and their droppings during pregnancy.
