| 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 |

| Kaisodi | 512/1024 | | 32/8 | 160 | Lanjan | 8/8 | | 128/512 | 320 |
| 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"". | |
