Fecal swabs obtained from all 77 turkey flocks were tested for the presence of RNA of any type of TAstV. RNA of turkey astrovirus was detected in swabs from 34 flocks (44%). For differentiation between different types of turkey astrovirus, three further tests were performed with published primers targeting various type-specific regions of the polymerase gene (Table 1) . Mixed infection with TAstV-1 and TAstV-2 was observed in swabs from six flocks (17.6%), and TAstV-2 was detected in 20 flocks (58.8%).
