Can humans with toxoplasmosis transmit the infection to their cats?

Great question! No, it is not shed in cat vomit, it is shed in the feces. When cats ingest infected prey or raw meat, the parasite is released from cysts in cat's digestive tract, where it reproduces and produces oocytes. Infected cats then excrete these oocytes in their feces by the millions, and will begin shedding them three to 10 days after consumed infected tissue. They will continue to shed oocytes for 10-14 days. I hope this helps!

Toxoplasmosis can be diagnosed by blood work or a fecal examination. However toxoplasma takes 24 hours after a bowel movement to become infectious. So if your sister cleans the box daily, and showers daily, and wears clean clothes daily then the likelihood of contamination approaches zero. I am a veterinarian, and touch cats daily, and had my antibodies tested before pregnancy and I have never been exposed. I hope this helps explain this for you. Best of luck and thank you for using Pet Coach.

Hi, thanks for using PetCoach! Your Doctor can test you. If you are negative then you should avoid gardening or doing things with the soil as toxoplasma lives there as well. Then I would have your husband clean Cecile's litter box or you do it wearing gloves and wash your hands. I would also keep your cats indoors. As a Vet, I have been exposed, who knows when or how, and I had a normal pregnancy. Below is a link to the CDC's page on toxoplasma. It should answer all of your questions! I hope this helps and I wish you the best! https://www.cdc.gov/parasites/toxoplasmosis/index.html

I'm sorry to hear about this. Toxoplasmosis is a parasite that is commonly acquired by cats, people and many other animals, but doesn't always cause disease. This means that any animal can be infected and shedding the infective stage, but doesn't necessarily have the disease. Unless Blink is having signs of illness, there is no need to treat the infection. However, it may be worthwhile to have a vet find out if she is in-fact the source of the infection. For your sake, it may be worthwhile to eliminate the infection in Blink, so she doesn't continually spread it. Keep in mind that cat's are not the only source of this disease. Many other animals can carry this parasite and it's often transmitted through undercooked meat. Below are links to a couple of articles that should be helpful for understanding this disease and making future decisions. https://vcahospitals.com/know-your-pet/toxoplasmosis https://www.cdc.gov/parasites/toxoplasmosis/index.html I hope that helps and you get better soon.

Not all cats carry toxoplasma and of those that do, they do not shed it everyday. The toxo eggs are not immediately infective in fresh faeces but take a day or so to mature and develop before they are spread to people if eaten. Brief contact with faeces which is washed off immediately is not a major concern as the mature eggs would need to be ingested in order to contract it

This has been a topic of study recently in human medicine, you can read some articles at https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2526142/ though the significance is not truly known yet, and this would be a question more suited to a human physician as they are trained in human medicine. I can tell you, however, that cats are not the only source of toxoplasma and individuals are much more likely to become infected from eating undercooked meat or contracting spores from gardening/vegetables in contaminated soil than from their cats themselves https://www.cdc.gov/parasites/toxoplasmosis/epi.html . If this is something you are concerned about you can clean your cat litterbox daily as the parasite requires 24 or more hours to sporulate and become infective, so if you scoop your litterbox daily and wash your hands well your risk from your cats is incredibly small.

Hello, coccidia is shed in the feces and rarely in vomit. Wash your hands after cleaning the litter box and clean any surface Oliver may have defecate on. The most common type of Coccidia that infects cats is species specific and it does not affect humans. Some more rare types of coccidia may infect humans such as cryptosporidium and toxoplasma, again also transmitted via a fecal to oral form or by eating raw meat. As long as you are washing your hands thoroughly and not handling fecal matter then you should be safe. Hope this helps and best of luck.
