Detection of Usutu virus RNA by one-step RT-PCR in tissue samples of blackbird (Turdus merula) cadavers. Prevalence indicates percentage of positive samples out of tested. Not all tissue samples were available for all individuals mostly due to tissue damage. Thus, tissue efficiency is expressed as a proportion of positively tested samples of a particular tissue from all positive individuals with that tissue available.
| Tissue | Prevalence (N Positive/N Tested) | Tissue Efficiency (N Positive/N Positive Individuals) | |||

| Locality | Prague 1 | Brno | Ceske Budejovice | Total | |
| Brain | 75% (6/8) | 41% (14/34) | 0% (0/12) | 35% (19/54) | 100% (20/20) |
| Liver | 75% (6/8) | 29% (10/34) | 0% (0/11) | 30% (16/53) | 84% (16/19) |
| Muscle | 75% (6/8) | 31% (11/35) | 0% (0/11) | 30% (16/54) | 84% (17/19) |
| Blood | 75% (6/8) | 17% (6/33) | 0% (0/9) | 24% (12/50) | 66% (12/18) |
| Total | 75% (6/8) | 40% (14/35) | 0% (0/12) | 36% (20/55) | |
