Evidence is mounting to link toxoplasmosis with schizophrenia

Keep pet cats inside, stop feeding strays, cook meat sufficiently and reconsider the way the veterinary profession and public health agencies think - and teach - about the zoonotic pathogen Toxoplasma gondii.
Such are the recommendations of Milton M. McAllister, a professor of pathobiology in the College of Veterinary Medicine at the University of Illinois at Urbana-Champaign. He delivered that message in Christchurch, New Zealand, at the 20th International Conference of the World Association for the Advancement of Veterinary Parasitology.
McAllister, also a clinical professor of pathology in the U. of I. College of Medicine at Urbana-Champaign, made his case based on his review of numerous studies on the animal-carried pathogen during the past decade. His review, prepared for the conference, appeared in the Sept. 30 issue of the journal Veterinary Parasitology.
"Our profession needs to come to grip with the accumulating body of evidence about the tremendous burden wrought on society by toxoplasmosis," McAllister wrote. "Further research is needed to clarify the association between toxoplasmosis and mental health, but until such time that this association may be refuted, it is my opinion that the current evidence is strong enough to warrant an assumption of validity."
