Toxoplasma gondii (Nicolle et Manceaux, 1908) is an obligate intracellular, parasitic protozoan within the phylum Apicomplexa that causes toxoplasmosis in mammalian hosts (including humans) and birds. Since meat of wild boar, Sus scrofa (Linnaeus), has been demonstrated to be a potential source of human infection, a careful evaluation of the prevalence of infection with T. gondii in hunted animals is needed to protect public health. In the Var area in southeastern France, we performed a spatio-temporal survey in order to investigate the prevalence of IgG antibodies in wild boars shot by hunters in the Canjuers military camp during two subsequent hunting seasons. Of 841 wild boars screened, antibodies (IgG) to T. gondii (modified agglutination test, cut-off 1 : 6) were found in 141 (16.8%) muscle extract samples. A significant association (p < 0.001) was found between positivity and age, but not gender, and hunting districts. The results obtained indicate that consumption of raw or undercooked meat from wild boars carries an important risk of infection with T. gondii. Wild boars may be considered as a bioindicator of parasite circulation in this ecosystem.
刚地弓形虫（Nicolle和Manceaux，1908年）是顶复门中的一种专性细胞内寄生原生动物，可在哺乳动物宿主（包括人类）和鸟类中引起弓形虫病。由于野猪（Sus scrofa，Linnaeus）肉已被证明是人类感染的潜在来源，因此需要仔细评估被捕猎动物中刚地弓形虫的感染率，以保护公众健康。在法国东南部的瓦尔地区，我们进行了一项时空调查，以研究在随后两个狩猎季节期间，在坎朱尔斯军营被猎人射杀的野猪中IgG抗体的流行情况。在841头接受筛查的野猪中，在141份（16.8%）肌肉提取物样本中发现了针对刚地弓形虫的抗体（IgG）（改良凝集试验，临界值1:6）。在阳性与年龄之间发现了显著关联（p<0.001），但与性别和狩猎区无关。所获得的结果表明，食用生的或未煮熟的野猪肉存在感染刚地弓形虫的重大风险。野猪可被视为该生态系统中寄生虫传播的生物指标。
