Cats are ideal pets for many because of their independence and behavior. For centuries, hundreds of cultures worshiped cats, but now the study destroys their image by claiming they are wearing a parasite that could erupt schizophrenia in humans.
Toxoplasma gondii spreads among humans through contact with cat trays and consumption of raw meat.
T. gondii, as is well known, will not usually hurt, but scientists from Copenhagen University have made research that appears to be the opposite because the risk of developing schizophrenia increases by 50 percent in those who have been infected with the virus.
More than 80,000 people were analyzed by experts from the University of Copenhagen in a Danish blood donation study, where 2,000 of 591 people with adverse psychiatric conditions were found.
It was Dr. Kristoffer Sølvsten Burgdorf, who led the analysis of specimens of infected people, sought traces of immunoglobulin antibodies in the presence of T. gondii.
This team detected a parasite in a quarter of the population studied in Copenhagen, of which 61 percent carried cytomegalovirus (CMV), a virus that also causes cognitive impairment.
The study found that those who are infected with T. gondii are almost 50% more likely to be diagnosed with schizophrenia than those who do not, according to the results.
This confirms that Toxoplasma has a positive effect on the rate of schizophrenia, "the researchers explain.
Dr. Collaborators Burgdorf explained that, for this reason, parasites combine with the onset of schizophrenia, except that they are not associated with any other psychiatric disorder.
This parasite can prevent the action of an amino acid in the body called tryptophan, which would cause a large number of metabolites, such as kinuric acid, a substance previously found in people with schizophrenia.
"Tryptophan is also an essential precursor to serotonin, which is involved in depressive disorders," the authors wrote.
According to the Daily Mail, the T. gondii parasite may cause infection in people called toxoplasmosis, which causes flu-like symptoms; while pregnant women may suffer from abortion or fatal labor.
Chicago University, meanwhile, said that nearly a third of the world's population is also infected with this virus that could cause psychological damage.
This college represents 60 million people in the United States and 350,000 in the United Kingdom.
A healthy immune system can fight it, so its symptoms are almost imperceptible.
