Field Comparison of Removed Substrate Sampling and Emergence Traps for Estimating Culicoides Orbivirus Vectors in Northern Florida

Journal of medical entomology, 2022
The larval ecology of Culicoides (Diptera: Ceratopogonidae) influences their spatial distributions and the pathogens they transmit. These features are of special concern for deer farmers in Florida where epizootic hemorrhagic disease virus (EHDV) is a ...

Isolation and characterization of orbivirus genotypic variants

Virus Research, 1987
Orbivirus variants containing either RNA deletions or concatemeric RNAs have been isolated. A variant of Ibaraki virus (a member of the epizootic hemorrhagic disease of deer serogroup) contained an RNA 9 segment which had terminal sequences identical to RNA 9 of wild type virus but was approximately 140 base pairs (bp) shorter.

Characterisation of Wongorr virus, an Australian orbivirus

Virus Research, 1996
Sequence analyses of VP3 gene segments of Wongorr virus isolates from the Northern Territory of Australia were compared with the cognate gene segments from Picola and Paroo River viruses. Previous serological investigations had demonstrated some relationships between these viruses, however VP3 gene sequence and phylogenetic analyses placed these ...

In vivo and in vitro propagation and transmission of Toggenburg orbivirus

Research in Veterinary Science, 2011
The Toggenburg orbivirus (TOV), a recently discovered virus related to bluetongue virus (BTV), has been identified in goats in Switzerland, Italy and Germany. Isolation of TOV in vitro has not yet been achieved and the transmission mechanisms are still unknown. In the experimental infection of pregnant goats described here, TOV could not be detected in

Seven-Year Prospective Study on Yearly Incidence of Orbivirus Infection of Captive White-Tailed Deer and Potential Culicoides vectors

Journal of medical entomology
Bluetongue virus (BTV) and epizootic hemorrhagic disease virus (EHDV) are arthropod-borne viruses that are transmitted by biting midges in the genus Culicoides (Diptera: Ceratopogonidae) and can cause hemorrhagic disease in certain ruminants.

The orbivirus genus. Diversity, structure, replication and phylogenetic relationships

Comparative Immunology, Microbiology and Infectious Diseases, 1994
The general properties of the orbiviruses have been examined at the physical, structural and molecular level. At the structural level, the orbiviruses (with the exception of the Kemerovo serogroup) appear similar. The replicative events are also similar, however differences in the ultrastructure of virus-specific structures and their association with ...

Characterization of Orungo virus, an orbivirus from Uganda and Nigeria

Archives of Virology, 1976
Orungo virus was studied in cell culture and mice by light and electron microscopy. The virus developed in the cytoplasm of infected cells in mouse brain and cell culture in association with a specific viral granular matrix and accompanying filaments. Virus particle size was 63 nm with a core diameter of 34 nm.

Occurrence and spatial distribution of Toggenburg Orbivirus in Switzerland

Small Ruminant Research, 2010
Abstract Recently, a new member of the Bluetongue virus (BTV) serogroup named Toggenburg Orbivirus (TOV) in goats from Switzerland has been described. The epidemiology and host range of TOV are currently unknown. Since TOV causes cross-reactions in laboratory tests used for BTV diagnosis, this study was carried out in order to determine the spatial ...

Detection of Toggenburg Orbivirus by a segment 2-specific quantitative RT-PCR

Journal of Virological Methods, 2010
Toggenburg Orbivirus (TOV) has been detected recently in healthy goats in Switzerland. The virus is related closely to bluetongue virus (BTV) and is considered tentatively as a 25th serotype of BTV. Upon detection of additional TOV-positive goats in Switzerland, Germany, and Italy, these TOV isolates were characterized genetically by partial sequencing
