Qalyub virus, a member of the newly proposed Nairovirus genus (bunyavividae)

Virology, 1981
Abstract Qalyub (QYB) virus, the prototype virus of the previously ungrouped QYB serogroup of arboviruses, has been shown by biochemical analyses of its structural polypeptides and virion RNA species to conform in broad terms to the criteria established for members of the Bunyaviridae family.

Genetic characterization of Erve virus, a European Nairovirus distantly related to Crimean-Congo hemorrhagic fever virus [PDF]

Virus Genes, 2012
Erve virus (ERVEV) is a European Nairovirus that is suspected to cause severe headache (thunderclap headache) and intracerebral hemorrhage. The mode of transmission to humans (ticks or mosquitoes) is still unknown. Currently, no standardized testing method for ERVEV exists and only a small partial sequence of the polymerase gene is available.

Coding strategy of the S RNA segment of dugbe virus (Nairovirus; Bunyaviridae)

Virology, 1990
The S RNA segment of Dugbe (DUG) virus (Nairovirus; Bunyaviridae) was sequenced from three overlapping cDNA clones and by primer extension. The S RNA is 1712 nucleotides in length and contains one large open reading frame (ORF) of 1326 nucleotides coding for a 49.4-kDa protein on viral complementary (vc) RNA. This protein in size corresponds to the DUG

Development of a loop-mediated isothermal amplification (LAMP) assay for the rapid detection of Beiji nairovirus

Microbial Pathogenesis
Beiji nairovirus (BJNV) is a recently discovered tick-borne RNA virus associated with human febrile illness. This study aimed to develop a loop-mediated isothermal amplification (LAMP) assay for the precise detection of BJNV, with a specific focus on assessing its effectiveness with clinical samples.

Immunofluorescence Studies on the Antigenic Interrelationships of the Hughes Virus Serogroup (Genus Nairovirus) and Identification of a New Strain

Journal of General Virology, 1983
Titrations of hyperimmune antisera by indirect immunofluorescence using each virus of the Hughes serogroup (Hughes, Zirqa, Punta Salinas, Soldado and Farallon) demonstrated their individual antigenic identities. Furthermore, an antigenically related virus, designated Puffin Island (PI) virus, was shown both by indirect immunofluorescence and by ...

RNA probes detect nucleotide sequence homology between members of two different nairovirus serogroups

Virus Research, 1990
Cloned cDNA derived from the small (S) and medium (M) genomic RNA segments of Dugbe (DUG) virus, isolate ArD44313, a member of the Nairobi sheep disease (NSD) serogroup of nairoviruses (family, Bunyaviridae) was used to prepare 32P-labelled DNA and RNA probes.

Experimental Infection of Six Species of Ixodid Ticks with Dugbe Virus (Family Bunyaviridae, Genus Nairovirus)

American Journal of Tropical Medicine and Hygiene, 1989
The vector potential of each of 6 species of colonized North American and African ixodid ticks was assessed by intracoelomic inoculation with Dugbe virus (IbAr 1792, 14th passage in suckling mouse brain) and viral titers were monitored after selected incubation periods.

Structure and morphogenesis of Dugbe virus (Bunyaviridae, Nairovirus) studied by immunogold electron microscopy of ultrathin cryosections

Virus Research, 1991
We have studied the structure and morphogenesis of Dugbe (DUG) virus (Bunyaviridae, Nairovirus) in cultured porcine kidney (PS) cells and a tick cell line (Ra 243) using immunogold electron microscopy. DUG virus is a tickborne arbovirus, considered to be a low health hazard, that is antigenically and genetically related to Crimean Congo haemorrhagic ...

Field and laboratory investigation of Crimean-Congo haemorrhagic fever virus (Nairovirus, family Bunyaviridae) infection in birds

Transactions of the Royal Society of Tropical Medicine and Hygiene, 1987
In November 1984 a case of Crimean-Congo haemorrhagic fever (CCHF) occurred in a worker who became ill after slaughtering ostriches (Struthio camelus) on a farm near Oudtshoorn in the Cape province of South Africa. The diagnosis was confirmed by isolation of CCHF virus from the patient's serum and by demonstration of a specific antibody response.

COMPARATIVE ANALYSIS OF NAIROVIRUS REPLICATION IN HYALOMMA-DERIVED TICK CELL LINES

2015
Background: Crimean-Congo hemorrhagic fever (CCHF) is a zoonotic viral disease that is asymptomatic in infected animals, but a serious threat to humans. Human infections begin with nonspecific febrile symptoms that progress to a serious hemorrhagic syndrome with a high case fatality rate. CCHF virus (CCHFV) is classified as a biosafety level 4 pathogen
