被猫咬伤后鲜为人知的危险

A number of studies in recent years have suggested a possible association between toxoplasma infections and an increased risk of serious psychological issues in humans, including schizophrenia and suicidal behavior. 'There's moderate evidence' of a link, said Robert H. Yolken, a professor at Johns Hopkins University who co-wrote a 2017 analysis examining research on toxoplasma and schizophrenia. One possible reason is that the parasite might boost the presence of the chemical dopamine in the brain, he said. Also, he said, any potential impact is likely more significant if the infection occurs at a young age.

近年来大量的研究已表明，在弓形虫感染与人类严重心理问题风险攀升――包括精神分裂症和自杀行为――两者之间可能存在着某种关联。约翰霍普金斯大学(Johns Hopkins University)教授罗伯特・H.约肯(Robert H. Yolken)说，“目前有一些证据”表明这种关联的存在。约肯于2017年与他人合着了一篇探讨弓形虫与精神分裂症研究的分析。他说，一个可能的原因是，寄生虫也许会增加大脑中化学物质多巴胺的分泌。他还称，如果感染发生在幼年期，任何潜在的影响都可能会更为显著。

Animal experts say proper precautions should minimize health risks from owning a cat. 'The presence of a cat in the house poses very little risk' for toxoplasma infection, said Jeffrey L. Jones, an epidemiologist at the Centers for Disease Control and Prevention. People shouldn't get infected if they are careful with litter boxes and wash and thoroughly cook their own food.
