Figure 1. Deaths of ducks in different barn units of farm B, Bavaria. A) Barn B/3–5; duck hatched April 25, 2007, slaughtered June 14, 2007, at an abattoir in Lower Saxony: no material available for testing. B) Barn B/3–5; duck hatched June 20, 2007, slaughtered August 1, 2007, at farm A): 2 highly pathogenic avian influenza virus (HPAIV) A (H5N1)–positive samples detected in retained samples of frozen duck carcasses; virologic and serologic results suggestive of a recent HPAIV (H5N1) infection are listed in the Table. C) Barn B/1–1; duck hatched June 29, 2007, slaughtered August 11, 2007, at farm A; subtype H5N1–specific RNA was detected in 1 retained sample of a frozen duck carcass, but the pathotype could not be determined due to low viral loads. D) Barn B/2–4; duck hatched July 20, 2007, culled September 9, 2007; virologic and serologic results suggestive of a recent HPAIV (H5N1) infection are listed in the Table.
