Dobrava hantavirus (DOB) was isolated from the striped field mouse (Apodemus agrarius) trapped on Saaremaa Island, Estonia, and its genetic and antigenic characteristics were subsequently analysed. Phylogenetic analysis showed that the Estonian DOB strain, together with several wild strains carried by Apodemus agrarius, forms a well-supported lineage within(More)
Hantaviruses (Bunyaviridae) cause hemorrhagic fever with renal syndrome (HFRS) in Eurasia and hantavirus (cardio)pulmonary syndrome (HCPS) in the Americas. HFRS is caused by Hantaan virus (HTNV), Seoul virus (SEOV), Dobrava virus (DOBV), Saaremaa virus (SAAV), and Puumala virus (PUUV). Of those, only HTNV is not present in Europe. In recent years,(More)
Genetic analysis was performed of wild-type (wt) Dobrava hantavirus (DOB) strains from Slovenia, the country where the virus was first discovered and where it was found to cause haemorrhagic fever with renal syndrome (HFRS), with a fatality rate of 12%. Two hundred and sixty mice of the genus APODEMUS:, trapped in five natural foci of DOB-associated HFRS(More)
In sharp contrast to human and nonhuman primates, guinea pigs and some other mammals resist Ebola virus (EBOV) replication and do not develop illness upon virus inoculation. However, serial passaging of EBOV in guinea pigs results in a selection of variants with high pathogenicity. In this report, using a reverse genetics approach, we demonstrate that this(More)
Phylogenetic analysis of three hantaviruses: Hantaan (HTNV), Dobrava (DOBV), and the newly designated serotype/genotype Saaremaa (SAAV) and their respective hosts, rodents of genus Apodemus, reveals a discrepancy in the virus-host relationships. While all Apodemus agrarius sequences from Europe and the Far East are monophyletic, SAAV (carried by the western(More)
Dobrava virus (DOBV) carried by Apodemus flavicollis is the causative agent of severe hemorrhagic fever with renal syndrome (HFRS). DOBV was isolated from an A. flavicollis mouse trapped in northeastern Greece. This is the third DOBV cell culture isolate in the world, clustering together with other Greek DOBV sequences from HFRS patients and rodents.
We previously developed a model for studies on hantavirus host adaptation and initiated genetic analysis of Puumala virus variants passaged in colonized bank voles and in cultured Vero E6 cells. With the data presented in this paper, the sequence comparison of the wild-type and Vero E6-adapted variants of Puumala virus, strain Kazan, has been completed. The(More)
The genus Hantavirus (family Bunyaviridae) includes negative-strand RNA viruses that are carried by persistently infected rodent and insectivore species. Puumala virus (PUUV), carried by bank voles (Myodes glareolus), is a pathogenic hantavirus that causes outbreaks of mild haemorrhagic fever with renal syndrome across Europe. In northern Europe, PUUV is(More)
The first complete genome sequence of Dobrava hantavirus isolated from yellow-necked mouse Apodemus flavicollis trapped in the northeastern Greece is described. The S, M, and L segments of the Greek isolate of Dobrava virus are 1673, 3635, and 6532 nucleotides (nt) long, respectively, and encode the nucleocapsid (N) protein of 429 amino acids (aa),(More)
