Among the five Polish TAstV-1 isolates, nucleotide identity was 97.4-99.8%, and amino acid identity was 98.2-100%. They were also closely related to the prototype TAstV-1 isolate, with identities of 95-95.5% at the nucleotide level and 98.2-98.8% at the amino acid level. The group of TAstV-1-like isolates was rather homogenous and included isolates from Poland, Brazil and the USA.
