Three replicate intrathoracic injection experiments indicate no effect of sfRNA on postmidgut dissemination of WNV in C. pipiens mosquitoesa
| Virus | Replicate | n | Positive bodies (no.) | Positive saliva (no.) | Infection (%) | Transmission (%) | Dissemination (%) |
|---|---|---|---|---|---|---|---|

| 2 | 13 | 13 | 11 | 100 | 85 | 85 | |
| 3 | 6 | 6 | 6 | 100 | 100 | 100 | |
| Total | 34 | 34 | 32 | 100 | 94 | 94 | |
| WNVΔSF1 | 1 | 19 | 19 | 17 | 100 | 89 | 89 |

Shown are infection, transmission, and dissemination rates of C. pipiens mosquitoes that were intrathoracically injected with either WNVIC or WNVΔSF1. In addition, the sample size (n) and absolute numbers of positive bodies and saliva samples are shown for each replicate.
