| | | Has been examined by CF and found unrelated to following viruses [2] : trivittatus-7941 (64), Anopheles A (64), Anopheles B (128), bat virus-Burns (128), Rio Bravo (128), Bunyamwera (64), Bwamba (32), Cache Valley (64), California (BFS-283)(32), chikungunya (256), Colorado tick fever (Florio)(64), dengue (Hawaii)(>8), dengue (NGB)(64), EEE (85)(128), herpes simplex (8), herpes simplex (E. Johnson) (32), Ilheus (256), Jap. enc. (Nakayama)(128), LCM (512), Mayaro (64), mouse virus-FA-660 (16), mouse virus-GD-7 (16), MVE (128), Ntaya (128), Powassan (128), RSSE (8), Sandfly fever-Sicilian (128), Semliki Forest (>512), Sindbis (128), St. Louis (Parton)(128), Turlock (64), Uganda S (128), WEE (85)(128), Wyeomyia (>512), YF-Jungle (256), YF (17D)(32), Zika (128). Cross tests were made with Chenuda Ar-1170 (128). The numbers in parentheses represent the reciprocal of the dilution of immune serum required to obtain complete complement-fixation with the homologous antigen. | | Though the prototype strains of Quaranfil (Ar-1113) and Chenuda (Ar-1170) and an Egyptian strain Ar-1304 used as prototype of Nyamanini did not show crossing by CF, two other Egyptian strains classed as Nyamanini did show slight one-way crossing with Quaranfil or Chenuda. | | Casals [3] was unable to detect antigenic crossing of Quaranfil, Nyamanini and Chenuda, and has placed CNU in the Kemerovo group. | | McIntosh [4] has reported isolation of a virus Ar-3441 from Argas peringueyi in South Africa which is very closely related if not identical with CNU. | | |
