Section V - Antigenic Relationship and Lack of Relationship to Other Viruses
 
Previous serological studies conducted in Ibadan indicated that these isolates were unrelated by CF to any viruses held at the Ibadan laboratory [2] .
Subsequently, 1:8 and 1:32 dilutions of a CF antigen for the IbAn 57245 strain (homologous titer = 256/64) were tested against and failed to react with a 1:4 dilution of the following NIH grouping fluids: Polyvalent Palyam (PAL, VEL, KAS, COR, ACD, EUB, PATA, DAG); Gr. Kemerovo; Polyvalent no. 8 (BLU, EHD, CGL, IRI, CTF, IbAr 22619). In addition, CF antigen and antibody for IbAn 57245 failed to react with systems for Eyach virus (256/>128), 5 strains of Orungo virus (32/64 to 256/32), Mitchell River virus (32/>32), Warrego virus (>256/>32), Japanaut virus (8/2), Lebombo virus (32/>32), and IbAr 39626 (256/>128). CF antigen for IbAn 57245 did not react with antibody to reovirus, type 3 (titer = 64). Umatilla rabbit antiserum (LNI = 3.0) did not neutralize Ife virus. YV177 virus (64/32), isolated from Eidolon helvum bats collected in Cameroun, reacted indistinguishably in CF with Ife virus and was considered to be a strain of Ife virus.
