At the epizcxMic of Bovine Epgemeral Fever (BEE) indairy cattle in 1984, the isolation of the causative virus was first atmpJ in Taiwan. From the febrile cattle (3 Hoistuins and 1 Hybrid) in southern Taiwan, 4 strains of BEF virus were isolati by intacerebral incxDulations in mice.
In the studies on the phyical characteristics of isolati virus, the micrcorganism sliowI susceptibility to various chemicals and treatment. With the studies on;
1 ,Crc€s neutralization est betwn the isolati vinis and the standard BE? virus. SUmmary
2.The findings of the srthfic fluoorescent antigen in BHK 221 cell culture aft the incculation of iso1ai virus,
3.Morphological obervation of the isolatei virus as a R}ia&Ioviridae virus by electron nthoscore,
4. Incculation of the isolatl virus repoducerl the symptoms of BE?, i,e, degesion, anorexia, pyrexia, excessive salivation and nasal discharge, tachypnea and articular riin caused lameness, the isolated virus was identifial as BE? virus.
