A cross-sectional study was carried out to determine the seroprevalence and to identify risk factors associated with Neospora caninum infection in 62 dairy herds (n = 671 cows) in Jordan between January and June 2007. Information regarding herd management was recorded through personal interviews with farmers. Antibodies against N. caninum were detected using an indirect ELISA test. Chi-square analysis and multivariable logistic regression model were used to identify risk factors associated with N. caninum seropositivity. The true prevalence of antibodies against N. caninum in individual cows and cattle herds was 35 and 66.5 %, respectively. There was no significant difference in the percentage of seropositive animals between different age groups. Multivariable logistic regression model revealed workers frequently visiting nearby farms as a risk factor for seropositivity to N. caninum, while presence of a calving pen was suggested as a protective factor. Amman, Balqa, and Mafrak governorates had significantly lower seroprevalence to N. caninum compared to other Jordanian governorates. Results of this study indicated that N. caninum infection may be widespread in Jordan.
2007年1月至6月期间，在约旦对62个奶牛场（n = 671头奶牛）开展了一项横断面研究，以确定犬新孢子虫感染的血清阳性率并识别相关风险因素。通过与养殖户进行个人访谈记录了有关牛群管理的信息。使用间接ELISA试验检测抗犬新孢子虫的抗体。采用卡方分析和多变量逻辑回归模型来识别与犬新孢子虫血清阳性相关的风险因素。个体奶牛和牛群中抗犬新孢子虫抗体的实际阳性率分别为35%和66.5%。不同年龄组之间血清阳性动物的百分比没有显著差异。多变量逻辑回归模型显示，工作人员频繁前往附近农场是犬新孢子虫血清阳性的一个风险因素，而有产犊栏则被认为是一个保护因素。与约旦其他省份相比，安曼、拜勒加和马弗拉克省的犬新孢子虫血清阳性率显著较低。本研究结果表明，犬新孢子虫感染在约旦可能广泛存在。
