Variant TAstV-2 may drive enteric disease with bursal atrophy in poults; extends experimental models but leaves open commercial relevance pending field studies.
TAstV-2 viruses with variant capsids produce similar enteric disease in young turkeys and may cause bursal lymphoid depletion.
Pantin‐Jackwood et al. (2008) studied Type 2 turkey astrovirus infection. Type 2 turkey astroviruses (TAstV-2) with variant capsid genes was evaluated on Clinical signs, virus shedding, and lesions. Inoculation of 2-day-old turkey poults with variant capsid type 2 turkey astroviruses caused enteric disease, virus shedding, and mild to moderate bursal atrophy in all examined birds.
