A pseudorabies virus(PRV)variant with enhanced pathogenicity has emerged in many vaccinated swine herds in China since 2011.rPRVTJ-delgE/gI,a previously described gE/gI-deleted PRV based on the PRV variant TJ strain,was shown to be avirulent to pigs yet virulent to sheep.

马传染性贫血病毒(EIAV)弱毒疫苗是通过经典弱毒疫苗致弱方式研制成功的首例慢病毒弱毒疫苗。为深入研究EIAV弱毒疫苗致弱机制，从基因水平确定影响病毒毒力和免疫原性的因素，本研究对EIAV疫苗株和亲本强毒株以及疫苗致弱过程中第3个中间代次(32代、62代和92代)病毒株的前病毒基因组进行测序分析。
登革热是一种由登革病毒感染引起,经蚊虫传播的传染性疾病.近年来,登革热疫情在热带和亚热带地区重复爆发并逐年加重.全球每年被感染的人数预计已达到3.9亿,其中约9600万感染者发展为症状性疾病,包括登革热、登革出血热、以及登革休克综合征.
