Fig. 4: Infectious virus and viral RNA detected in tissues.
From: Experimental Usutu virus infection in Eurasian blackbirds (Turdus merula)
a The amount of infectious virus in several tissues collected postmortem from the infected blackbirds is expressed in TCID50/g of tissue. Results averaged from three individuals for USUV Afr3 and USUV Eu3 groups, bars represent SD. A statistically significant difference (*p = 0.02) was observed between USUV Afr3 titer (2,3 × 109 TCID50/g) and USUV Eu3 titer (1 × 108 TCID50/g). b The amount of viral RNA detected in the lung and pallium of infected blackbirds is expressed in Ct value. Results averaged from three individuals for Afr3 and Eu3 groups, bars represent SD. No statistically significant differences were observed in either of the two tissues (lung p = 0.1; pallium p = 0.8).
