摘要
食源性病毒是指以食物为载体,导致人类发生疾病的病毒。按照病毒的不同来源,食源性病毒可分为肠道食源性病毒和人畜共患的食源性病毒两大类,肠道食源性病毒包括以粪便直接或间接污染食物,通过粪口途径使病毒传播给人类的病毒;人畜共患的食源性病毒是指一些人畜共患,以畜禽产品为载体传播的病毒。本文阐述了食源性病毒的种类、生物学特性、流行病学特征、研究现状,阐明了近年来以PCR为基础的分子生物学检测方法及存在的问题,提出了食源性病毒今后进一步研究的发展方向及实际应用前景。
Foodbome viruses are defined to be viruses that can lead to human diseases through food. In accordance with the different origin, foodborne viruses can be divided into two kinds: intestinal viruses and zoonotic viruses. The former include those viruses that can be transmitted to person via fecal-orally route. The latter include those zoonotic viruses that chiefly transmitted to person through livestock and poultry products. This paper expounds foodborne viruses categories, biology nature, epidemiology character, and study circumstance, and clarifies the molecular biological methods and problems on the base of the polymerase chain reactions, and presents the development direction and application perspective of the foodbome viruses study.
