摘要

接收日期：修订日期：接受日期：在线发布日期：2019年6月11日2019年7月9日2019年07月10日2019年06月30日搁浅是一种马的传染性细菌性疾病，在全球范围内流行。宿主限制性马链球菌是马亚种的病因。2019年4月，在一个集约化驴场的隔离区，一头驴被诊断为勒死。通过临床症状、细菌分离、组织化学、聚合酶链式反应和测序证实感染。基于M蛋白分型方法，对测序数据的分析表明，分离的马S.equi菌株CN190402属于一个新的基因型SeM-138。本研究增加了对马的分子流行病学的了解，并将有助于更好地了解这种病原体的多样性。同时，它强调了隔离区的必要性和生物安全对集约化驴场的重要性，以防止未来疫情的爆发。©2019 PVJ。保留所有权利

Identification of a Novel Genotype of Streptococcus equi Subspecies equi in a Donkey Suffering from Strangles

Received: Revised: Accepted: Published online: June 11, 2019 July 09, 2019 July 10, 2019 July 30, 2019 Strangles is a contagious bacterial disease of equines and is prevalent worldwide. Host-restricted Streptococcus equi subspecies equi is the etiology. In April 2019, strangles was diagnosed in a donkey in the quarantine area of an intensive donkey farm. The infection was confirmed by clinical signs, bacterial isolation, histochemistry, PCR and sequencing. Based on the M-protein typing method, analysis of SeM sequencing data indicated that the isolated S. equi strain CN190402 belongs to a novel genotype SeM-138. The present study increases knowledge of the molecular epidemiology of S. equi and will lead to a greater understanding of the diversity of this pathogen. Meanwhile, it emphasized the necessity of quarantine areas and the importance of biosecurity for intensive donkey farms to prevent future outbreaks. ©2019 PVJ. All rights reserved
