From: The pathogenicity of swan derived H5N1 virus in birds and mammals and its gene analysis
Virus replication in beagles after inoculation with the H5N1 influenza virus strain SW/3/06. Tissue homogenates were prepared from the animals that died post-infection with the SW/3/06 virus via either the i.n. or i.t route. Viral titers were determined in ECEs and expressed as EID50 per gram for tissue samples and EID50 per ml for tracheal and cloacal swabs. The limits of virus detection (horizontal dotted lines) for tissues and swabs were 1.75 and 0.75 log10 EID50, respectively (*P <0.05, ***P <0.001; two-way ANOVA followed by Tukey’s multiple comparisons test).
