Infection source can determine cost-effective public health interventions. To quantify risk of acquiring Toxoplasma gondii from environmental sources versus from meat, we examined serum from pregnant women in Chile. Because 43% had oocyst-specific antibodies, we conclude that contaminated meat remains the primary source of infection but that environmental sources also pose substantial risk.
感染源可确定具有成本效益的公共卫生干预措施。为了量化从环境来源和肉类中感染弓形体的风险，我们检测了智利孕妇的血清。由于 43%的血清具有卵囊特异性抗体，我们得出结论，受污染的肉类仍然是主要的感染源，但环境来源也构成了重大风险。
