|   |  |  Employing Kaisodi antiserum prepared in mice, HI tests were carried out with 8 units of each of the following antigens:   |  |   |  
  |  
  |  |       Group A:       |       EEE, WEE, VEE, Mayaro, chikungunya, Semliki Forest, Sindbis, Getah, Bebaru, Middelburg, Aura;       |  |       Group B:       |       yellow fever, Wesselsbron, Zika, Banzi, Spondweni, West Nile, dengue 2, MVE, Ntaya, RSSE, Powassan, St. Louis, JE;       |  |       Others:       |       Ilesha, Bunyamwera, Germiston, California, Tahyna, Marituba, Oriboca, Caraparu; Bwamba, Sathuperi, Ketapang, Bakau, Neapolitan and Sicilian sandfly fevers, Akabane, Manzanilla, Witwatersrand and Koongol.       |  
  |  |  The serum failed to inhibit agglutination at a dilution of 1:10 or higher.    |  |  In CF tests, there was no cross-reaction between Kaisodi and any of the following tickborne viruses: Quaranfil, Chenuda, Nyamanini (EgAr 1304), Wad Medani, Ganjam (IG 619), Wanowrie, Silverwater, Colorado tick fever, Hughes virus and Kemerovo. There was some cross-reaction between Kaisodi and a Malayan virus, strains Lanjan and TP 123, obtained from Dr. Gordon Smith. This cross-reaction could be detected by CF as well as HI tests.   |  |   |  |   |       Antigens       |

  |  |  The KSO serogroup presently consists of Lanjan and Silverwater viruses in addition to Kaisodi virus. These serogroup viruses are considered as possible members of the Bunyaviridae family                                                      [8]                                              and therefore, are listed taxonomically as ""bunyavirus-like"".   |  |   |
