| | | By CF G15534 antigen did not react with (homologous titer in parenthesis) hyperimmune sera against Sindbis (256), chikungunya (256), Japanese encephalitis (512), West Nile (256), dengue 2 (256), Kyasanur Forest disease (256), Venkatapuram (128), Ganjam (256), Umbre (>64), Sathuperi (16), Minnal (32), Kaisodi (64), Arkonam (128), Wanowrie (128), Wad Medani (256), Bhanja (256), Batai (256), bluetongue (128), AHS (>64), HEV (256), Chandipura (>64), Blalgodu (>64). | | CF tests carried out by Dr. R.E. Shope at YARU indicated that there was no reaction with immune ascitic fluids against Colorado tick fever, Eubenangee, Corriparta, Kemerovo, Chenuda, Wad Medani, Tribec, Lebombo, EHD and Changuinola. | | Related by CF to Palyam (G5287) and Vellore (68886) viruses but distinct by neutralization test. | | Antigenic relationship among Palyam, Kasba and Vellore viruses. | | | | | Immune Sera |
