| | | HI test: | | Mouse hyperimmune serum for Ponteves tested against 8 units of each of the following antigens: Sindbis, chikungunya, yellow fever, West Nile, SLE, Ntaya, MVE, dengues 1 and 2, CEE, Bunyamwera, Tahyna, Sicilian SF, Naples SF. The serum diluted 1:10 failed to inhibit HA. | | CF test: | | The following hyperimmune sera or ascitic fluids were tested against Ponteves antigen (homologous titer with mouse serum 128/32*): Group A, Group B, Group Bunyamwera, Group Sandfly fevers, West Nile, Tahyna, Grand Arbaud, Uukuniemi [2] . | | An immune serum against Potepli virus, a strain of Uukuniemi virus [3] , was also included in the test. | | The only positive results were as follows: | | | | | Antiserum |
|---|
| Antigen | Ponteves | Grand Arbaud | Uukuniemi | Potepli |
|---|
|
| | * Serum titer/antigen titer; - = <2/<2 | | Ponteves | 128/32 * | 16/32 | 4/16 | - | | Grand Arbaud | 2 /2 | 64/32 | 64/8 | - | | Uukuniemi | - | 2/8 | 32/16 | 64/64 |
| | These reactions suggest a relationship between Ponteves and Uukuniemi; and also a one-sided relationship between Ponteves and Grand Arbaud. However, Grand Arbaud is not identical to Uukuniemi. | | |
