is a parasitic protozoan, the etiological agent of toxoplasmosis, a worldwide zoonosis responsible for abortion and congenital malformation in animal and human. The present study reports, for the first time, the occurrence of infection among sheep and goats from Benin. A total of 368 small ruminants: 215 serum samples from sheep raised in Sahelian area of North Benin and 153 serum samples from goats raised in a family farm from South-Benin, were collected and screened for anti- IgG antibodies by the ELISA-indirect method. The results show the presence of anti- IgG in 53% (83/153) of goats and 1.4% of sheep (3/215). Age, sex and breed did not seem to affect the frequency of this infection. Among goats, infection was higher in animals reared in the coastal zone (Cotonou municipality) than those raised on the island (Allada municipality) [odds ratio (OR) = 4, 95% confidence interval (CI) = 1.07-15.002, = 0.032, (χ) test]. Humidity would be the determining factor in the disparity of recorded infection rates among sheep and goat. The high prevalence of caprine toxoplasmosis observed in southern Benin shows strong environmental contamination. Sensitization campaigns should therefore be undertaken by the public health authorities to inform the inhabitants of this area about risks and preventive measures of this zoonose.
是一种寄生原生动物，是弓形虫病的病原体，弓形虫病是一种全球性人畜共患病，可导致动物和人类流产及先天性畸形。本研究首次报告了贝宁绵羊和山羊中感染的发生情况。共采集了368只小反刍动物：来自贝宁北部萨赫勒地区饲养的绵羊的215份血清样本和来自贝宁南部一个家庭农场饲养的山羊的153份血清样本，并采用间接ELISA法检测抗IgG抗体。结果显示，53%（83/153）的山羊和1.4%的绵羊（3/215）存在抗IgG。年龄、性别和品种似乎不影响这种感染的频率。在山羊中，沿海地区（科托努市）饲养的动物感染率高于岛屿地区（阿拉达市）饲养的动物[优势比（OR）=4，95%置信区间（CI）=1.07-15.002，P=0.032，（χ）检验]。湿度可能是绵羊和山羊感染率差异的决定因素。在贝宁南部观察到的山羊弓形虫病高流行率表明环境污染严重。因此，公共卫生当局应开展宣传活动，告知该地区居民这种人畜共患病的风险和预防措施。
