TAstV-1 was first described in 1980 and mainly detected in the USA [18] . Recently, the presence of TAstV-1 was also confirmed in Brazil (data based on available sequences in GenBank: TAst-1/Brazil/2009/USP350-3B: GU938473, TAst-1/Brazil/2009/USP351-1A: GU938474). Regarding ANV, at first, only antibodies against ANV were detected in turkeys in Japan and the UK, and the first isolation and sequencing was achieved in 2006 in the USA [6, 17, 18] . In our study, the presence of an ANV-like isolate in a Polish turkey flock was detected, and this is, to the authors' knowledge, the first time this virus has been detected outside the USA.
