BACKGROUND
Past research linked Toxoplasma gondii (TG) infection in humans with neurological and mental disorders (e.g., schizophrenia, Alzheimer's disease and attention disorders), irregularities of the dopaminergic and testosterone system, and increased likelihood of being involved in traffic accidents.
METHODOLOGY/PRINCIPAL FINDINGS: We test for an association between TG infection and financial decision-making (DM) using a case-control design in a sample of female Czech students (n = 79). We estimate each subject's risk attitude and loss aversion using an experimental economic task involving real monetary incentives. We find no significant evidence that either measure of decision-making is associated with TG infection.
CONCLUSION
We were unable to find evidence of an association between TG infection and financial decision-making in females.
背景
过去的研究将人类感染弓形虫（TG）与神经和精神障碍（如精神分裂症、阿尔茨海默病和注意力障碍）、多巴胺能和睾酮系统异常以及交通事故参与可能性增加联系起来。
方法/主要发现：我们在一组捷克女学生样本（n = 79）中采用病例对照设计，测试TG感染与金融决策（DM）之间的关联。我们使用一项涉及真实货币激励的实验性经济任务来估计每个受试者的风险态度和损失厌恶。我们没有发现显著证据表明任何一种决策指标与TG感染有关。
结论
我们未能找到女性TG感染与金融决策之间存在关联的证据。
