Thai Disease Center Warns Pussy-Cat Lovers

Published

A Thai Parasite Disease Research Center warns pussy-cat lovers to be careful with their feline friends after finding a 30-year-old male living in Thailand with 5 mm lesions in his right eye and 1 mm in his left.  The culprit? Most likely his pussy cat.

After examinations and tests, it was determined his lesions were related to a disease called chorioretinal toxoplasmosis. A common disease carried by both wild and domestic cats called toxoplasma gondii or T. gondii T.  When a cat eats an infected mouse, rat, or any other prey that carries the parasite, they themselves become infected when digesting raw meat. A parasite is then released from cysts into the cat’s digestive tract, where it reproduces and produces oocysts.

Infected cats then excrete these oocysts in their feces by the millions. When the parasites leave the cysts of the infected meat, they will penetrate even more into the wall of the cat’s intestines which in return multiply into another form, called a tachyzoite. It then spreads from the intestine to other parts of the cat. Eventually, the cat’s immune system forces the parasite lays dormant until cysts grow in the cat’s muscles and the brain. Eventually mutating into yet another form, called a bradyzoite.

In some cases, T. gondii tachyzoites may be excreted in the milk of infected cows and goats.

Pregnant women and immunodeficient people have the highest risk of developing health problems after getting exposed to T. gondii . Women infected during pregnancy will show no symptoms themselves. Unfortunately, their infected infants will show no symptoms either, In fact, most will only show signs of infection until much later in life, including loss of vision and hearing, mental retardation, and, in severe cases, death.

This infection is found all over the world,  people get it by eating raw or unheated meat, and eating and drinking food or water that was contaminated by cat feces.

Also, it can cause irreversible ulcerations and scarring, causing sore eyes, the tearing of the retina, and blurred vision

For answers to specific questions regarding toxoplasmosis infection in people, please consult with your health care professional.

There is no vaccine to protect against toxoplasmosis in animals or humans.
