|   |  |  In CF and HI tests, with crude alkaline extract of infected SM brain as antigen, 78TWM-106 reacted only with a flavivirus grouping MIAF. No reactions were observed when 78TWM-106 antigen was tested with 47 other immune mouse ascitic fluids representing more than 250 arboviruses plus rabies, mouse hepatitis and Theiler's GDVII viruses. Sal Vieja virus (78TWM-106) was found to be most closely related to Modoc, Jutiapa, Cowbone Ridge, Rio Bravo, and Apoi flaviviruses.   |  |   |  |   |       Sal Vieja antigen       |       Sal Vieja antibody       |
