Abstract

The Simbu serogroup is one of the serogroups that belong to the genus of the family . Simbu serogroup viruses are transmitted mainly by biting midges. Meager information is available on Simbu serogroup virus infection in ruminants in Sudan. Therefore, in this study, serological surveillance of Simbu serogroup viruses in cattle in seven states in Sudan was conducted during the period from May, 2015, to March, 2016, to shed some light on the prevalence of this group of viruses in our country. Using a cross-sectional design, 184 cattle sera were collected and tested by a commercial SBV ELISA kit which enables the detection of antibodies against various Simbu serogroup viruses. The results showed an overall 86.4% prevalence of antibodies to Simbu serogroup viruses in cattle in Sudan. Univariate analysis showed a significant association (=0.007) between ELISA seropositivity and states where samples were collected. This study suggests that Simbu serogroup virus infection is present in cattle in Sudan. Further epizootiological investigations on Simbu serogroup viruses infection and virus species involved are warranted.

摘要

辛布血清群是属于该科属的血清群之一。辛布血清群病毒主要通过叮咬蠓传播。关于苏丹反刍动物感染辛布血清群病毒的信息匮乏。因此，在本研究中，于2015年5月至2016年3月期间对苏丹七个州的牛群进行了辛布血清群病毒的血清学监测，以了解我国该类病毒的流行情况。采用横断面设计，收集了184份牛血清样本，并使用商用SBV ELISA试剂盒进行检测，该试剂盒能够检测针对各种辛布血清群病毒的抗体。结果显示，苏丹牛群中针对辛布血清群病毒的抗体总体流行率为86.4%。单因素分析显示ELISA血清阳性与样本采集州之间存在显著关联（=0.007）。本研究表明苏丹的牛群中存在辛布血清群病毒感染。有必要对辛布血清群病毒感染及相关病毒种类进行进一步的流行病学调查。
