Cats are ideal pets for many because of their independence and behavior. For years, hundreds of cultures have worshiped cats, but now research is destroying their image, claiming that they carry a parasite that can explode schizophrenia in humans.
Toxoplasma gondii is distributed to people through contact with cat litter trays and the consumption of raw meat.
T. gondii is also generally known to do no harm, but researchers from the University of Copenhagen have conducted studies that seem to prove the opposite, since the risk of developing schizophrenia increases by 50 percent for people infected with the virus.
More than 80 thousand people were analyzed by specialists of the University of Copenhagen in the framework of the Danish study of blood donors, where 2 thousand 591 people with adverse mental disorders were found.
It was Dr. Kristoffer Selvsten Burgdorf who led the analysis of samples of infected people to find traces of antibodies to immunoglobulin in the presence of T. gondii.
The team found a parasite in a quarter of the population studied in Copenhagen, of which 61 percent of people had been suffering from cytomegalovirus (CMV), a virus that also causes cognitive impairment.
The study showed that those who are infected with T. gondii are almost 50% more likely to have a diagnosis of schizophrenia than those who do not, according to the results.
This "confirms that Toxoplasma has a positive effect on schizophrenia," the researchers explained.
The staff of Dr. Burgdorf explained that for this reason they attributed the parasite to the appearance of schizophrenia, and not to any other mental disorder.
This parasite can prevent the action of an amino acid in the body, called tryptophan, which can cause a large number of metabolites, such as kinurenic acid, a substance previously encountered in people with schizophrenia.
"Tryptophan is also an important precursor of serotonin, which is involved in depressive disorders," the authors write.
According to the Daily Mail, the T. gondii parasite can cause an infection in humans, called toxoplasmosis, which causes flu-like symptoms; while pregnant women can suffer miscarriage or stillbirth.
Meanwhile, the University of Chicago stated that almost a third of the world's population is also infected with this virus, which can cause psychological damage.
This university school has 60 million affected in the United States and 350 thousand in the United Kingdom.
A healthy immune system can fight it, so its symptoms are almost imperceptible.
