The study was conducted in Basrah, Iraq, to diagnose congenital arthrogryposis-hydranencephaly syndrome caused by Akabane virus (AKAV) in calves.
Affected animals (42 calves) are about 2-27 days old from both sexes show signs of arthrogryposis and hydranencephaly. Eight clinically healthy newborn calves were considered as controls. Diagnosis of AKAV was confirmed using a competition enzyme-linked immunosorbent assay test.
Results show that all affected calves were found seropositive. Furthermore, a significant increase in total leukocyte count in diseased calves due to a significant increase in the absolute lymphocyte number indicated in affected calves than in controls. Moreover, a significant increase in sedimentation rate of erythrocytes was also encountered in diseased calves than in controls. In addition, a significant increase in haptoglobin level and fibrinogen was also detected.
Diagnosis of AKAV infection of Basrah Governorate, Iraq, will provide useful epidemiological information for cattle and other domesticated animals. Therefore, abortion could be prevented and controlled.
该研究在伊拉克巴士拉进行，旨在诊断由赤羽病毒（AKAV）引起的犊牛先天性关节弯曲-积水性无脑综合征。
患病动物（42头犊牛）年龄在2至27天之间，雌雄均有，表现出关节弯曲和积水性无脑的症状。8头临床健康的新生犊牛被视为对照。使用竞争酶联免疫吸附试验确诊AKAV感染。
结果显示所有患病犊牛血清呈阳性。此外，患病犊牛的总白细胞计数显著增加，这是由于患病犊牛的绝对淋巴细胞数量比对照显著增加所致。而且，患病犊牛的红细胞沉降率也比对照显著增加。此外，还检测到触珠蛋白水平和纤维蛋白原显著增加。
对伊拉克巴士拉省AKAV感染的诊断将为牛和其他家畜提供有用的流行病学信息。因此，可以预防和控制流产。
