| | However BA 365 is related to Yaba 1 as shown by following cross CF tests [3] : | | | | | Turlock | Umbre | Yaba 1 | BA 365 | |
|---|
| Antigens | Ascitic fluid | Serum | Serum | Ascitic fluid | |
|---|
|
| | Turlock | 64/256 | 64/64 | 16/64 | 4/256 | | | Umbre | 8/16 | 128/64 | 8/4 | 2/4 | | | Yaba 1 | 8/64 | 16/64 | 256/256 | 16/1024 | | | BA 365 | 4/64 | 16/64 | 256/64 | 16/256 | |
| | On further testing, M'Poko was found to be indistinguishable from Yaba-1 by cross CF and NT [5] . | | Neutralization data shown on the Lednice virus registration card indicate that Yaba 1 and M'Poko viruses manifest two-way differences [7] . | | |
