猪捷申病毒分子生物学研究进展

猪捷申病是由猪捷申病毒(Porcine teschovirus,PTV)引起的猪脑脊髓灰质炎、繁殖障碍、肺炎、下痢、心包炎和心肌炎、皮肤损伤及无症状等多种表现的一种病毒性传染病。该病在大多数猪场呈隐性感染,其致病机制、分子机理、与其他病毒的相互作用尚不十分清楚。同时,该病在国内外研究较少。论文主要综述了猪捷申病毒的分子生物学研究进展,并对其研究前景进行了展望。

Advance in Molecular Biology of Porcine Teschovirus

Porcine teschovirus(PTV)was described as causative agents of severe and mild neurological disorders known as Teschen/Talfan disease,which callsed reproductive failure,pneumonia,diarrhea,and dermal lesions of swine.Nowadays PTV presents subclinical infection,and its pathogenic mechanism,molecular mechanism and interaction with other viruses are not clear.Meanwhile,the study of PTV was little in the world as well as its report in china.The purpose of this article was to review the advances in the study of PTV molecular biology and its prospects.
