Hemafiplutinating Properties of Viruses of the Phlebotomus Fever Group

摘要: Summary The hemagglutinating properties of 10 viruses the phlebotomus fever group were studied using antigens derived from infected newborn mouse brain tissue; prepared by sucrose-acetone extraction and sonication. hemagglutination reaction is practically not temperature-dependent. pH range for Bujaru, Iran-47, Karimabad Salehabad 6.0 to 6.4, Anhanga, Chagres, Naples Sicilian sandfly it 6.8. optimal all but Anhanga virus 6.2. Treatment erythroeytes with trypsin enhances their susceptibility in extends reaction. use trypsinized permits demonstrate Punta-Toro which does react native erythroeytes. Erythrocytes one-day-old chickens rooster trypsin-treated ery~hrocytes might be used equally as well goose erythrocytes; 0 human erythrocytes hamster are less susceptible. Chicken have some advantages inhibition test.
