Snippet: When the samples were tested by RT-PCR for virus shedding evaluation, the AAstV specific RNA was sequentially detected from the cloacal swabs of infected goslings from 2 to 12 dpi (Fig. 6 ). Viral RNA could still be detected in the liver and spleen when the infected birds were killed at 15 dpi. Neither viral shedding nor positivity in the tissue samples was detected in the uninfected control goslings during the experiment. Infected goslings showe.....
Document: When the samples were tested by RT-PCR for virus shedding evaluation, the AAstV specific RNA was sequentially detected from the cloacal swabs of infected goslings from 2 to 12 dpi (Fig. 6 ). Viral RNA could still be detected in the liver and spleen when the infected birds were killed at 15 dpi. Neither viral shedding nor positivity in the tissue samples was detected in the uninfected control goslings during the experiment. Infected goslings showed decreased body weight gain and the average body weight of infected birds was statistically significantly lower than that in the uninfected group from 6 dpi to the end of the experiment (Fig. 7) . The average body weight in the infected group was 322 ± 73 g versus 370 ± 15 g in the control group at 6 dpi, and 625 ± 180 g versus 878 ± 48 g at 14 dpi, respectively.
