A virus strain was isolated from the arthrosis of broiler chickens.The virus was shown to have spherical particles with isometric symmetry,no envelope,double deck capsids,with outer capsid of 75nm,inner one of 50nm in diameter by electron microscopy.The virus was not sensitive to aether,acid and heat.The virus could multiply on the chick embryo fibroblastcell,and could cause syncytial pathologic change with the appearance of cytoplasm inclusion bodies.The challenged chickens of one-day old by nasal,oral,intramuscular and pulvillus injection displayed obvious clinical symptom of severe arthritis and accompanied with pathological changes of malabsorption and necrosis.Meanwhile,four avian reovirus isolates CL,S1133,YH and YB were examined in the cross-neutralization test.
