Trials for the isolatation of the bluetongue virus on tissue cultures

The following investigations were ’carried out in ord to study the optimum condition for bluetoD6ue-virus isolation. After adding type-16 bluetongue-virus to washed sheep erythrocytes, most of the virus particles (7:; %) were found to be associated with ehisher infectivity titres were detected in VERO cells then followed by BHK c211s. 3- Parallel titration of the same sample of bluetongue- virus in embr-yo natd.ng 10-days-old chicken egGs by intravenous inocuiation showed hibher titre in cell cultures. 4-
