| identification and pcr-restriction fragment length polymorphism analysis of a variant of the ibaraki virus from naturally infected cattle and aborted fetuses in japan. | one 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 ... | 1999 | 10565887 |
| 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 ... | 2003 | 14665759 |
