To investigate the prevalence of Toxoplasma gondii infection in free-ranging Eurasian lynx (Lynx lynx) in Sweden, serosanguinous fluids and feces were collected from 207 carcasses of lynx killed or found dead from 1996 to 1998. Sera were tested for antibodies against T. gondii by the direct agglutination test, and 156 (75.4%) of the sera tested positive at antibody titers>or=40. Antibody prevalence was significantly lower in lynx originating from the northern parts of Sweden than in lynx from the more southern regions that are more densely populated by humans. Age-related differences also were found, with a significantly lower prevalence (55%) in juvenile (<1-yr-old) than in subadult and adult animals (82%). There was no significant difference in seroprevalence between males and females. Oocysts typical of T. gondii were not detected in any of the fecal samples.
为调查瑞典野生欧亚猞猁（Lynx lynx）弓形虫感染的流行情况，于1996年至1998年间从207只被猎杀或发现死亡的猞猁尸体上采集了血清样液体和粪便。通过直接凝集试验检测血清中抗弓形虫抗体，156份（75.4%）血清抗体滴度≥40时检测呈阳性。瑞典北部猞猁的抗体流行率显著低于瑞典南部人口更为密集地区的猞猁。还发现了与年龄相关的差异，幼年（<1岁）猞猁的流行率（55%）显著低于亚成年和成年动物（82%）。雄性和雌性之间的血清阳性率没有显著差异。在任何粪便样本中均未检测到典型的弓形虫卵囊。
