Course Description: Found worldwide, Toxoplasma gondii is a ubiquitous parasite that typically causes most people no harm—or so we think! Known to have a predilection for the nervous system and to be a danger mainly to pregnant patients' fetuses and to immunocompromised hosts, researchers are beginning to uncover more subtle pathologies associated with Toxoplasma infection. This course will cover the biology and life cycle of Toxoplasma gondii, immunology, prevalence and epidemiology, laboratory testing, and pathology. It will then focus on newer research demonstrating a relationship between Toxoplasma seropositivity and a number of mental changes and disorders, including risk-taking behavior, depression, suicide, substance abuse, and especially schizophrenia.
