| | | No hemagglutinin has been prepared from MRM3630, but mouse antiserum to the virus (after 3 or 4 weekly intraperitoneal inoculations) did not inhibit hemagglutination by Group A (Sindbis, Getah, Ross River), Group B (Murray Valley encephalitis) or Koongol group (Koongol, Wongal) antigens. | | Complement-fixation tests (using mouse serum collected after 4 weekly intraperitoneal inoculations) showed a relationship to Mapputta virus (MRM186) but not to the following viruses isolated in Australia - Sindbis, Getah, Ross River, Murray Valley encephalitis, Kunjin, Kokobera, Edge Hill, Stratford, Koongol, Wongal, Corriparta, Kowanyama and Eubenangee or to Japanese B encephalitis, dengue virus, types 1-4 and Bebaru. | | Neutralization tests showed no relation to any of the viruses previously isolated in Australia. | | | | Virus or antigen | Serum |
