Women infected with Toxoplasma gondii have increased risk of attempting suicide: study

Women infected with the Toxoplasma gondii (T. gondii) parasite, which is spread through contact with cat feces or eating undercooked meat or unwashed vegetables, are at increased risk of attempting suicide, according to a new study of more than 45,000 women in Denmark. A University of Maryland School of Medicine psychiatrist with expertise in suicide neuroimmunology is the senior author of the study, which is being published online today in the Archives of General Psychiatry.
