A low-titered relationship demonstrated by CF, fluor. antibody and indirect
HA between CON and NSD viruses (9,10). SIRACA has decided that these relations
are no greater than those used to establish BUN Supergroup. The CON and NSD
antigenic groups should be kept as two distinct serogroups. Intergroup
relationships also were demonstrated for members of the DGK, HUG, QYB, and SAK
serogroups as well as for members of the above-mentioned two serogroups (12).
Dugbe virus has been classified as a member of the Nairovirus genus in the
family Bunyaviridae (13).
