How to prevent and cure Toxoplasma gondii infection in dogs during pregnancy

First, pay attention to dietary hygiene, meat should be fully cooked, to avoid raw meat pollution of cooked food.

Second, cats should be kept at home and fed cooked food or finished cat food so that they are not allowed to hunt outside. Because cats are infected by eating infected mice or birds, or eating food that pollutes cat droppings.

Third, we should pay attention to daily hygiene, remove cat droppings every day, and wash hands carefully after contact with animal feces.

Fourth, avoid contact with cats and their feces during pregnancy unless the maternal serum test proves that Toxoplasma gondii has been infected.

Fifth, Toxoplasma gondii infection has a variety of simple and effective drug treatment, such as sulfonamides plus pyrimethamine, and spiramycin, treatment must be carried out in accordance with the doctor's advice, timely treatment of maternal infection can reduce the chance of fetal infection.

The first is to eat undercooked meat, especially pigs and sheep. Almost all mammals and birds, such as rodents, pigs, sheep, cattle, rabbits and chickens, ducks and geese, can be infected with Toxoplasma gondii, and the infection rate is very high. The source of human infection mainly comes from the meat of these animals, such as the temperature of rinsing meat is not enough and the time is too short, in which Toxoplasma gondii is not killed, there is a risk of infection. Pollution from raw meat or meat cutting boards can also be contagious. Contaminated sheep and milk can also be infected. The infection rate of Toxoplasma gondii in the above-mentioned Chinese population is relatively low, which may be related to the cooked meat habits of the Chinese people.

Dogs can also infect Toxoplasma gondii, but their faeces and feces are not contagious and will not be transmitted if they do not eat dog meat. Some people say that "dogs have a close relationship with people and are one of the important sources of infection of human beings." there are also children born with "mental retardation, congenital heart disease or an extra finger," which are blamed on keeping dogs at home, all of which are unfounded.

Infected cat droppings are an important source of infection. Cats and cats are the ultimate hosts of Toxoplasma gondii, and cystoses are excreted from the feces of infected cats, usually lasting from 1 week to 20 days, with very few; this is the period of infection.

About 1% of cat feces around the world contain Toxoplasma gondii zygotes. The zygote in cat feces must be developed in the outside world for 2 to 5 days before it can be contagious, so when to dispose of cat feces is very important. Zygotes can survive in water and moist soil for months or longer, so food, drinking water and even dust contaminated by cat droppings can be contagious when eaten. Cats are an important source of human transmission in areas where cooked meat is complete. However, it has been suggested that it is impractical to control toxoplasmosis by eliminating domestic cats. Because many other animals that act as intermediate hosts can also spread.

For example, there are many pastures where there are very few cats, and many cattle and sheep are infected; and there are individual islands in the world that do not have cats, and the infection rate among islanders is still very high. Therefore, there is an important book "Human Parasitology" in China that says: because the infection rate of livestock as an intermediate host is very high, so from the source of human infection, the pollution of cat dung is less important than eating undercooked meat.

Pregnant women infected with Toxoplasma gondii can be transmitted to the fetus, resulting in congenital infection, as congenital infection of the fetus may have serious consequences, so it is very important. However, only a pregnant woman who has not been infected with Toxoplasma gondii before pregnancy has the first (primary) infection during pregnancy can be transmitted to the fetus. If a pregnant woman is infected with Toxoplasma gondii before pregnancy, she is no longer at risk of infection.
