Abstract

Genetic analysis of virus detected in autopsy tissues of a fatal hantavirus pulmonary syndrome-like case in Louisiana revealed the presence of a previously unrecognized hantavirus. Nucleotide sequence analysis of PCR fragments of the complete S and M segments of the virus amplified from RNA extracted from the tissues showed the virus to be novel, differing from the closest related hantavirus, Sin Nombre virus, by approximately 30%. Both genome segments were unique, and there was no evidence of genetic reassortment with previously characterized hantaviruses. The primary rodent reservoir of Sin Nombre virus, the deer mouse Peromyscus maniculatus, is absent from Louisiana. Thus, the virus detected in Louisiana, referred to here as Bayou virus, must possess a different rodent reservoir.

摘要

对路易斯安那州一例类似汉坦病毒肺综合征致死病例尸检组织中检测到的病毒进行基因分析,结果显示存在一种此前未被识别的汉坦病毒。从组织中提取的RNA扩增出的病毒完整S和M片段的PCR产物进行核苷酸序列分析,结果表明该病毒是新病毒,与亲缘关系最近的汉坦病毒——辛诺柏病毒相比,差异约为30%。两个基因组片段均是独特的,没有证据表明它与先前鉴定的汉坦病毒发生了基因重配。路易斯安那州没有辛诺柏病毒的主要啮齿动物宿主——白足鼠(鹿鼠)。因此,在路易斯安那州检测到的这种病毒(此处称为河口病毒)必定有不同的啮齿动物宿主。
