Further Studies on HA and HI Test for EHF
Abstract: In this paper, we have modified the HA and HI test for EHF. EHFVHAN was made by Tween_(80)-ether method as well as by sucrose-acetone method. Higher HA titer of EHFV-HAN was obtained by Tween_(80)-ether method. The pigeon crythrocytc was most sensitive to the EHFV-HAN among 6 sorts of red blood cells. Frozen pigeon crythrocytes have been used instead of fresh goose erythrocytes.
