“…Before the 1980s, Ibaraki virus (IBAV), a strain of epizootic hemorrhagic disease virus (EHDV) serotype 2, was involved in large outbreaks of diseases in cattle characterized by fever and deglutitive disorder (Forman et al., ). Recently, Peaton, Sathuperi and Shamonda viruses (PEAV, SATV and SHAV) of the genus Orthobunyavirus and D'Aguilar virus (DAGV) of the genus Orbivirus were newly confirmed and were thought to be involved in congenital malformations of cattle (Matsumori et al., ; Ohashi et al., ; Yanase et al., , ). D'Aguilar virus is regarded as a strain of Palyam virus (PALV) together with CHUV, and a genetic reassortant was probably generated between the two viruses (Ohashi et al., ).…”

Epizootic congenital abnormalities, encephalomyelitis and febrile illnesses in cattle caused by arthropod-borne viruses (arboviruses) are prevalent in Japan. Causative viruses including orthobunyaviruses, orbiviruses and rhabdovirus are thought to be transmitted by Culicoides biting midges. Recently, the incursions of several arboviruses, potentially Culicoides-borne, were newly confirmed in Japan. However, their spread pattern and exact vector species are currently uncertain. Attempts to isolate arboviruses from Culicoides biting midges and sentinel cattle were conducted in Kagoshima, located at the southernmost end of the main islands of Japan, a potentially high-risk area for incursion of arboviral diseases and outbreak of endemic ones. Seventy-eight isolates comprising Akabane, Peaton and Sathuperi viruses of the genus Orthobunyavirus of the family Bunyaviridae, bluetongue virus serotype 16, D'Aguilar virus, Bunyip Creek virus and epizootic haemorrhagic disease virus serotype 1 of the genus Orbivirus of the family Reoviridae, a potentially novel rhabdovirus of the genus Ephemerovirus and unidentified orbivirus-like viruses were obtained from Culicoides biting midges and sentinel cattle between 2003 and 2013. Akabane, Sathuperi, D'Aguilar and Bunyip Creek viruses were selectively isolated from Culicoides oxystoma, suggesting this vector's responsibility for these arbovirus outbreaks. The results of virus isolation also implied that C. tainanus, C. jacobsoni and C. punctatus are competent for the transmission of bluetongue virus serotype 16, Peaton virus and epizootic haemorrhagic disease virus serotype 1, respectively. Our monitoring in Culicoides biting midges and sentinel cattle detected the circulation of Akabane virus just prior to the accumulations of bovine congenital abnormalities and encephalomyelitis by it around study sites in 2003, 2006, 2008 and 2013. Silent circulations of the other arboviruses, including potentially new viruses, were also detected during the study period.

“…The viruses are most frequently detected from Culicoides oxystoma in southwestern Japan (Yanase et al , 2005). Peaton virus, which is closely related to Aino virus and has been isolated from Culicoides brevitarsis in Australia, is also distributed in southern Japan (Matsumori et al , 2002). These data suggest that C. oxystoma and C. brevitarsis are the most important bovine arbovirus vectors in southwestern Japan.…”

Partial mitochondrial gene sequences of 16 Culicoides species were determined to elucidate phylogenetic relations among species and to develop a molecular identification method for important virus vector species. In addition, the analysis found mitochondrial gene rearrangement in several species. Sequences of the mitochondrial genome region, cox1-trnL2-cox2 (1940-3785 bp) of 16 Culicoides and additional sequences were determined in some species, including whole mitochondrial genome sequences of Culicoides arakawae. Nine species showed common organization in this region, with three genes cox1-trnL2-cox2 and a small or no intergenic region (0-30 bp) between them. The other seven species showed translocation of tRNA and protein-coding genes and/or insertion of AT-rich non-coding sequences (65-1846 bp) between the genes. The varied gene rearrangements among species within a genus is very rare for mitochondrial genome organization. Phylogenetic analyses based on the sequences of cox1+cox2 suggest a few clades among Japanese Culicoides species. No relationships between phylogenetic closeness and mitochondrial gene rearrangements were observed. Sequence data were used to establish a polymerase chain reaction tool to distinguish three important vector species from other Culicoides species, for which classification during larval stages is not advanced and identification is difficult.

“…These viruses are most frequently traced to Culicoides oxystoma Kieffer in southwestern Japan (Kurogi et al 1987, Miura et al 1988, Kurogi et al 1989, Yanase et al 2005. Peaton virus, closely related to Aino virus, was isolated from Culicoides species in Okinawa, in southern Japan (Matsumori et al 2002). JapanÕs livestock and other animals are threatened by infection of bluetongue virus (Goto et al 2004).…”

We determined nucleotide sequences of the nuclear rDNA internal transcribed spacer (ITS)1-5.8S-ITS2a-2S-ITS2 region in 103 individuals of 25 Culicoides species (Diptera: Ceratopogonidae) from 11 locations in Japan. Ribosomal RNA genes, 5.8S and 2S rDNA, were highly conserved among the species with few variations. The ITS2a region showed length variation among species. Both ITS1 and ITS2 showed highly varied sequences among species. The noticeable indel regions among ITS1 sequences are present in some Culicoides species, separating species into two types having long or short ITS1 region. However, Culicoides cylindratus Kitaoka possesses both types of ITS1 in each individual; these results seem to indicate that the ITS1-long type was the prototype and the short type was produced through deletion in many Culicoides species. One species, belonging to subgenus Avaritia, possessed an Avaritia-specific sequence in ITS1 and phylogenetically formed a monophyletic group. Geographical genotypes in a species were not clear. Species-specific sequence features were observed, enabling molecular identification of Culicoides species.
