| | | CF antigen failed to fix complement in the presence of the following immune reagents: SLE, FLA, rabies, groups VSV, TCR, SIM, KEM, GMA, CAP, CAL, C, ANA, ANB, TUR, B, BWA, CON, PAL, PAT, QRF, numerous NIH grouping HIAF's. Strain TBM3-24 was shown to be closely related or identical to strains TBM3-204 and TBM4-719 [1] . HIAF to strain TBM3-204 reacted by CF with PHL group members CHG and BUJ at YARU [2] . HI tests with strain TBM4-719 and 31 grouping fluids showed inhibition of HA activity only with PHL group HIAF [2] . | | | | | Rio Grande Antigen/Virus | Rio Grande Antibody |
