ibaraki disease and its relationship to bluetongue.ibaraki disease, an epizootic disease of cattle in japan resembling bluetongue, is characterized by fever and lesions affecting the mucous membranes, the skin, the musculature and vascular system. degeneration of striated muscular tissue is observed in the oesophagus, larynx, pharynx, tongue and the skeletal muscles. oedema and haemorrhage are marked in the mouth, lips, abomasum, around the coronets, etc., and are occasionally followed by degeneration of the epithelium leading to erosions or ulc ...1975169788

identification and pcr-restriction fragment length polymorphism analysis of a variant of the ibaraki virus from naturally infected cattle and aborted fetuses in hundred fourteen field isolates of the ibaraki virus (ibav), a member of the epizootic hemorrhagic disease virus serotype 2 (ehdv-2), were isolated from blood samples of affected and apparently healthy cattle and culicoides biting midges and from blood samples of dams and internal organs of aborted fetuses during an outbreak of ibaraki disease in the southern part of japan in 1997. in this outbreak, 242 cattle showed typical symptoms of the disease, and several hundred dams had miscarriages ...199910565887
differences in ibaraki virus rna segment 3 sequences from three epidemics.phylogenetic tree and partial nucleotide sequence analysis of rna segment 3 were conducted to compare the ibaraki virus (ibav) strains from three epidemics in japan, and serotype 2 epizootic hemorrhagic disease virus strains isolated in australia, taiwan, and canada. each strain was classified relative to the ibaraki disease (ibad) epidemics, which occurred in 1959-1960, 1987, or 1997-1998. in particular, major variation of the gene was identified in the strains isolated after 1997 when a new ty ...200314665759
the begomoviruses honeysuckle yellow vein mosaic virus and tobacco leaf curl japan virus with dnabeta satellites cause yellow dwarf disease of tomato.the complete nucleotide sequences of two begomoviruses (nara virus-1 and nara virus-2), a satellite dna (dnabeta-nara) and defective dnas were obtained from honeysuckle (lonicera japonica) showing characteristic yellow vein mosaic symptoms in nara prefecture, japan. one begomovirus (ibaraki virus) and a satellite dna (dnabeta-ibaraki) was isolated and cloned from honeysuckle plants exhibited typical yellowing of veins and small elliptical shaped enations along veins on the under side of the leav ...200818722488
serological survey of arthropod-borne viruses among wild boars in japan.a total of 90 blood samples were collected from wild boars in the kyushu region of japan, and a seroepidemiological survey for 7 arthropod-borne viruses was performed using hemagglutination inhibition tests. the individual seropositive rates for each virus were 52.2% for japanese encephalitis virus (jev), 47.8% for getah virus (getv), 13.3% for akabane virus, 10.0% for aino virus and less than 5% for bluetongue virus, chuzan virus and ibaraki virus. the results indicated that among the 7 viruses ...200919721358
reemergence of ibaraki disease in southern japan in japan in 2013, two cattle in the northwestern part of kagoshima prefecture developed fever and swallowing difficulty and were suspected of having ibaraki disease. the epizootic hemorrhagic virus (ehdv) genome was detected from diseased and asymptomatic cattle by reverse transcription-polymerase chain reaction (rt-pcr). high neutralization antibody titers to ibaraki virus (ibav) ranging from 1:128 to 1:1,024 were observed in the rt-pcr-positive cattle, and the virus was isolated in one of the ...201526018356
