The aim of this study was to determine the seroprevalence of antibody to Neospora caninum in healthy and aborted dairy cattle in Tabriz, capital of East-Azarbaijan in northwest of Iran.
In this cross-sectional study serum samples were collected from 266 healthy and aborted Holestein-Feriesisnc cows from September 2008 to August 2009. The sera were analyzed to detect of antibody against N. caninum using the commercially ELISA kit.
Seroprevalence of antibody to N. caninum was 10.5% in Tabriz dairy cattle. Also the abortion rate in all cattle sampled was 33.6% but percentage of seropositive aborted cattle was 18.4%.
Neosporosis could be one of the possible causes of abortion in dairy cattle in Tabriz and regarding the distribution in dogs as definitive host for the parasite, further studies in dog and cattle are recommended.
本研究旨在确定伊朗西北部东阿塞拜疆省首府大不里士健康及流产奶牛中新孢子虫抗体的血清阳性率。
在这项横断面研究中，于2008年9月至2009年8月从266头健康及流产的荷斯坦 - 弗里生奶牛采集血清样本。使用商业ELISA试剂盒分析血清以检测抗新孢子虫的抗体。
大不里士奶牛中新孢子虫抗体的血清阳性率为10.5%。所有采样奶牛的流产率为33.6%，但血清阳性流产奶牛的比例为18.4%。
新孢子虫病可能是大不里士奶牛流产的可能原因之一，鉴于该寄生虫的终末宿主犬的分布情况，建议对犬和牛进行进一步研究。
