摘要/Abstract

摘要： 牛环曲病毒（bovine torovirus，BToV）是套式病毒目（Nidovirales）托巴套氏病毒科（Tobaniviridae）环曲病毒属（Torovirus）的成员，是重要的牛腹泻病原。该病毒对呼吸道和消化道具有双重组织嗜性，也是一种可能的呼吸道致病因子。BToV已经在中国、美国、日本等17个国家检出，具有广泛的地域分布。该病毒在国内是新发病毒，本文就BToV的分子生物学特性、流行概况、所致疾病的临床症状与病理变化、检测方法等研究进展做一综述，以期为BToV的研究提供参考。

Abstract: Bovine torovirus (BToV) belongs to the subgenus Renitovirus, genus Torovirus, family Tobaniviridae, and order Nidovirales. This diarrhea-causing bovine pathogen has dual tissue tropism and implicating this virus is a possible causative agent for bovine respiratory disease. BToV has been reported in 17 countries, such as China, the United States, Japan, with a worldwide geographical distribution. To provide a reference for BToV research, this review describes the latest research progress on BToV, including the biological characteristics, epidemiology, clinical symptoms and pathology, detection methods.
