概括

这项研究调查了人类原始帕尔沃病毒 (PPV) 感染,发现尽管血清流行率高,但急性布法病毒和古塔病毒感染率低. 急性PPV感染在一般人群中似乎很少见,轻微或局部.

科学领域:

病毒学病毒学
免疫学免疫学免疫学
流行病学流行病学

背景情况:

原型帕尔沃病毒 (PPV),包括布法病毒 (bufavirus),库塔病毒 (cutavirus) 和图萨病毒 ( tusavirus),是最近在人类中发现的帕尔沃病毒家族的新成员.
这些病毒与各种疾病有关,包括胃肠炎和皮肤T细胞淋巴瘤,有些病毒是动物源的.

研究的目的:

开发新的酶免疫试验 (EIAs) 用于检测人类原型帕维病毒IgM抗体.
为了寻找和描述急性人类原型帕尔沃病毒感染.
为各种人群提供PPV血清流行情况的综合分析.

主要方法:

从六个国家的十个队伍中选了1444个血清样本,使用内部IgG,IgM和PCR测定.
分析来自不同健康状况的个体的样本,包括无法解释的发烧,胃肠炎和慢性疾病.
开发和应用新的PPV IgM EIAs用于急性感染检测.

主要成果:

布法病毒的血清发病率在地理位置上有所不同,伊朗的发病率高,芬兰和意大利的发病率低.
在患有慢性疾病的成年人和老年人中,形病毒IgG血清流行率显著高 (>10%).
在任何队列中都没有检测到 tusavirus IgG 抗体. 在确认性测试后,高IgM反应性并未证实急性感染.

结论:

建议急性人类原型帕维病毒感染是轻微的,局部的或罕见的.
该研究没有发现呼吸道感染或胃肠炎病例中急性PPV感染的证据.
高血清流行率表明过去广泛暴露于布法病毒和古塔病毒,但急性感染并不常见.

关键词:

这是一种急性感染.布法病毒 (Bufavirus) 是一种病毒.皮疹病毒 (Cutavirus) 是一种病毒.流行病学流行病学原生病毒 (Protoparvovirus) 是一种原生病毒.血清的流行程度是如此.我们的病毒 Tusavirus.

Mechanisms of Retrovirus-induced Cancers

Mechanisms of Retrovirus-induced Cancers

Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...

Viral Recombination

Viral Recombination

Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.
