Abstract
Vero [African green monkey kidney] cell cultures and embryonating chicken eggs were used for direct isolation of bluetongue virus from cattle blood and from semen samples. Cell culture and embryonating chicken eggs each were more effective than was the blood autograft inoculation of susceptible sheep with selected blood and semen samples. Evaluation of the cell culture technique indicated that the quality of the distilled water was the primary factor responsible for the increased sensitivity of the Vero cell cultures for the present bluetongue viral isolations. Urine was a poor specimen for viral isolation when assayed in chicken eggs. A comparison of tests for precipitating and complement-fixing antibodies to bluetongue virus indicated that the precipitin test was the more accurate of the 2 tests.
