Cats infect people with parasites, turning them into violent zombies

A group of scientists led by Emma Wilson from University of California, riverside, as it affects the behavior of humans and mice affected by the parasite Toxoplasma gondii in domestic cats, and what are the biological mechanisms that influence. Experts have confirmed that “brainwash” their hosts parasites cause mice not to fear cats, and also found that they make people prone to inexplicable fits of rage and more spontaneous behavior in General.

In experiments on mice, the experts found that toxoplasmosis infection leads to disturbances in the glutamate, a key signal substances in the brain. This amino acid plays a role khimicheskogo carrier of information between nerve cells. Toxoplasmosis triggers the disabling of the gene GLT-1, is involved in the destruction of “extra” molecules of glutamate in the cells that protect the neurons from infection and damage. As a result, glutamate, according to scientists, begins to accumulate in the brain, which, apparently, and changes the behavior of humans and mice.

According to the researchers, their findings show that chronic infection with the parasite Toxoplasma gondii, found in many domestic cats may be slightly more dangerous to humans than is commonly believed. In order to avoid toxoplasmosis, experts strongly recommend good to fry meat, wash hands thoroughly and vegetables, and pregnant women — not to touch the tray with kitty litter.

Their findings the researchers presented on the pages of the scientific journal PLoS Pathogens.

By the way, a study conducted in the US in the early twenty-first century showed that almost a third of the country’s residents over the age of 12 were found Toxoplasma-specific IgG antibodies, indicating that they were ever infected with Toxoplasma. It is assumed that only those hosts infected up to 65 per cent of all mankind.
