The Molecular Biological Characterization of Peste des Petits Ruminants Virus and Its Prevalence in the World
摘要/Abstract
小反刍兽疫由副粘病毒科麻疹病毒属小反刍兽疫病毒引起，经直接或间接接触传染，主要感染山羊、绵羊等小反刍动物，严重影响畜牧业，造成巨大经济损失。1942年首次发现于西非科特迪瓦，逐渐扩散至非洲及亚洲大部，涉及四十余国家。2007年7月首次传入中国西藏阿里地区，并于2008年6月再度爆发，且呈由边境逐渐向内传播的趋势。该地区有多种珍贵濒危野生反刍动物，是小反刍兽疫病毒的潜在宿主，它们随季节迁徙及夏季产仔的习性更增加其受小反刍兽疫感染并传播小反刍兽疫的可能。因此，对小反刍兽疫病毒的生物学特征、流行特点和防控措施进行综述，必将有利于正确评估小反刍兽疫对野生有蹄类动物的威胁并采取合适的措施预防与控制小反刍兽疫疫情。
Peste des petits ruminants ( PPR) caused by peste des petits ruminants virus ( PPRV) , which be - longs to Morbillivirus, Paramyxoviridae, is an acute and highly contagious viral disease of small ruminants such as sheep and goats and causes great economic impact on livestock industry. It was first described in Cote d? Ivoire in West Africa, and spread to most part of Africa and Asia, involving more than 40 countries in all. The viruses transmitted in Asia are of the same lineage while the PPRV in different districts are divided into 4 lineages. In 2007, 4 outbreaks of goats infected by PPRV were reported in Ali district in T ibet, where several rare and endangered wild steppes are living, which are probably reservoirs that can transmit or infect PPRV. If so, the migration habits of these steppes may cause endemics of PPR. Here, biological features,epidemiological characteristics, andcontrol measures of PPRV are summarized, which may be helpful for assessing the risk of PPR to wild steppes and taking appropriate measures to control and prevent PPR.
