Viruses of the Simbu serogroup are arboviruses that are known to cause outbreaks of abortion, stillbirth and congenitally deformed neonates. This study presents the results of antibody screening of Simbu serogroup viruses in heifers born in Israel after October 2013, and in adult milking cows born before May 2012. Thirteen dairy cattle farms in five regions, and one sheep flock, entered this study. Serum samples that were found to be positive by ELISA were further tested by specific virus- neutralization test against a panel of Simbu serogroup viruses including Akabane, Aino, Sathuperi, Shamonda, and Peaton viruses. Antibody detection in lactating adult cows revealed that several viruses were circulating in Israel between 2008-2014. Moreover, during autumn 2014 the heifers became serum-positive after being exposed to more than one Simbu serogroup virus concurrently. The results of this study shed new light on Simbu virus infections in Israel, and may contribute to the epidemiology of the Simbu serogroup around the Mediterranean Basin in general.
辛布血清群病毒属于虫媒病毒，已知可引发流产、死产以及新生儿先天性畸形疫情。本研究呈现了对2013年10月之后在以色列出生的小母牛以及2012年5月之前出生的成年泌乳奶牛进行辛布血清群病毒抗体筛查的结果。来自五个地区的13个奶牛场以及一个羊群参与了本研究。通过酶联免疫吸附测定（ELISA）检测呈阳性的血清样本，进一步针对一组辛布血清群病毒进行特异性病毒中和试验，这些病毒包括赤羽病毒、爱诺病毒、萨图佩里病毒、沙蒙达病毒和皮顿病毒。对泌乳成年奶牛的抗体检测显示，2008年至2014年期间以色列有几种病毒在传播。此外，在2014年秋季，小母牛在同时接触了不止一种辛布血清群病毒后血清呈阳性。本研究结果为以色列的辛布病毒感染提供了新的线索，总体上可能有助于了解地中海盆地周边地区辛布血清群的流行病学情况。
