Danish scientists have discovered that monoclonal toxoplasmic parasites, often present in cats, increase the risk of schizophrenia in humans.
According to a study published by ScienceDirect, experts badyzed the data of nearly 82,000 people in a large-scale study of blood donors. In about 3,000 cases, mental disorders were discovered. The experts examined the presence of toxoplasmosis in the blood of people with mental illness and concluded that the infection increased the risk of schizophrenia by 50%.
In addition, they noticed that the element had appeared in the human body before the doctors diagnosed mental illness.
The study confirmed that toxoplasmosis had a positive effect on the development of schizophrenia.
Scientists have stressed the need to further study the effects of parasites on human health.
Toxoplasma (Toxoplasma gondii) is an intracellular parasite that lives in the intestines of domestic cats. Lead to the onset of toxoplasmosis – a disease that is usually easy, but with a decrease in immunity, can have serious consequences.
Larvae of parasites can enter the human body through the raw meat of infected farm animals or by contacting an infected pet. The disease is widely spread among humans around the world. Until now, according to US Centers for Disease Control and Prevention, more than 60 million people have been infected in the United States.
Previously, scientists claimed that toxoplasmosis can alter the behavior of the host, causing irreversible changes in the brain. For example, mice and chimpanzees are no longer "scared" by seeing the smell of cats and leopards, and people are prone to suicide, irrational acts and tantrums that can not be explained.
