Nowadays, many families are keeping pets, but once someone in the family is pregnant, the question arises whether the pet can be kept or not. I often get this question from mothers-to-be or mothers-in-law during my clinic visits. Usually the mother-in-law asks her daughter or daughter-in-law to give away the dogs and cats, but the daughter or daughter-in-law usually refuses to give away the pets, each trying to convince the other. The reason the mother-in-law asks for the dog or cat to be given away is that the mother-to-be may get Toxoplasma gondii from exposure to them, causing fetal abnormalities. The daughter or daughter-in-law has some minor concerns but is really reluctant to give up the cute dogs and cats. I usually side with my daughter-in-law or daughter-in-law because cats are suspect and dogs are wrongly accused. All kinds of wild critters, poultry and fish can be infected with Toxoplasma gondii, and if a pet comes into close contact with these wild critters, poultry and fish infected with Toxoplasma gondii, it is possible to get Toxoplasma gondii. Cats are the ultimate host of Toxoplasma gondii, and although there is cat food available, many cats will often run outside and eat indiscriminately, so there is a greater suspicion of contracting Toxoplasma gondii. However, if a better-behaved cat only eats cat food and does not go wild outside, there is no suspicion. Dogs are only intermediate hosts for Toxoplasma compared to the final host, cats, and therefore are not very contagious. And dogs generally eat dog food, have regular vaccinations, and do not go out into the wild alone to catch mice and eat dead poultry, so the probability of contracting Toxoplasma gondii is small. So the dog was wrongly accused, and wrongly accused for many years, I am here even to vindicate the dog. The advice on Toxoplasma and other TORCH tests is: do not advocate all pregnant women to check, only in high-risk groups, preferably before pregnancy, pregnancy tests are best in early pregnancy, do not wait until mid-pregnancy, otherwise it will cause a lot of difficulties and trouble in interpretation. As for IgG and IgM antibodies, and how to perform further confirmatory questions, they will not be introduced. Because these issues are not clear even to general obstetricians, it is best to leave it to experienced prenatal diagnosticians to avoid misinterpretation. Dogs and cats can be implicated, but if a misinterpretation leads to harm to the child, the consequences will be serious.
