Seroconversion of tree shrews and guinea pigs inoculated or contact with SW2783 and ZZ346 influenza viruses.
| Viruses | Inoculated | Direct contact | ||
|---|---|---|---|---|
| animals | HI titersa | animals | HI titersa | |
| SW2783 | tree shrews | 3/3 (8, 9, 8) | tree shrews | 3/3 (7, 7, 8) |
| guinea pigs | 3/3 (6, 7, 6) | guinea pigs | 2/3 (4, 6) | |
| tree shrewsb | 3/3 (7, 8, 8) | guinea pigsb | 3/3 (7, 6, 5) | |
| guinea pigsb | 3/3 (6, 7, 7) | tree shrewsb | 0/3 | |
| ZZ346 | tree shrews | 3/3 (7, 6, 8) | tree shrews | 1/3 (5) |
| guinea pigs | 3/3 (4, 4, 5) | guinea pigs | 0/3 | |
| tree shrewsb | 3/3 (7, 7, 6) | guinea pigsb | 0/3 | |
| guinea pigsb | 3/3 (6, 5, 5) | tree shrewsb | 0/3 | |
a
Seroconversion of the infected or exposed animals was tested by HI assay on 21 days post inoculation or post exposed. Seroconversion: no. positive/no. total (HI titers, log2).
b
Animals were used for the inter-species transmission study.
