Dogs play an important role in rabies transmission throughout the world. In addition to the severe human rabies situation in China, spillover of rabies virus from dogs in recent years has caused rabies outbreaks in sheep, cattle and pigs, showing that there is an increasing threat to other domestic animals. Two livestock rabies outbreaks were caused by dogs in Shanxi province, China from April to October in 2015, resulting in the deaths of 60 sheep, 10 cattle and one donkey. Brain samples from one infected bovine and the donkey were determined to be rabies virus (RABV) positive by fluorescent antibody test (FAT) and reverse transcription polymerase chain reaction (RT-PCR). The complete RABV N genes of the two field strains, together with those of two previously confirmed Shanxi dog strains, were amplified, sequenced and compared phylogenetically with published sequences of the N gene of RABV strains from Shanxi and surrounding provinces. All of the strains from Shanxi province grouped closely, sharing 99.6 %-100 % sequence identity, indicating the wide distribution and transmission of dog-mediated rabies in these areas. This is the first description of donkey rabies symptoms with phylogenetic analysis of RABVs in Shanxi province and surrounding regions. The result emphasizes the need for mandatory dog rabies vaccination and improved public education to eradicate dog rabies transmission.
狗在全球狂犬病传播中起着重要作用。除了中国严峻的人间狂犬病形势外,近年来狗传播的狂犬病病毒还导致绵羊、牛和猪发生狂犬病疫情,这表明对其他家畜的威胁日益增加。2015年4月至10月,中国山西省发生了两起因狗引起的家畜狂犬病疫情,导致60只绵羊、10头牛和1头驴死亡。通过荧光抗体试验(FAT)和逆转录聚合酶链反应(RT-PCR),确定来自1头感染牛和那头驴的脑样本为狂犬病病毒(RABV)阳性。扩增了这两株野毒株以及之前两株已确认的山西犬株的完整RABV N基因,进行测序,并与山西省及周边省份已发表的RABV株N基因序列进行系统发育比较。山西省的所有毒株紧密聚类,序列同一性为99.6%-100%,表明狗介导的狂犬病在这些地区广泛分布和传播。这是山西省及周边地区首次对驴狂犬病症状及RABV进行系统发育分析的描述。该结果强调了强制进行犬类狂犬病疫苗接种和加强公众教育以根除犬类狂犬病传播的必要性。
