I have added a new video to the Newcastle disease section, as it provides a useful illustration for differential diagnosis.
In practice, I frequently encounter the persistent belief that torticollis is, in itself, a definitive sign of Newcastle disease. This misconception remains widespread, yet the diagnosis of Newcastle disease is inherently complex and cannot be made on the basis of a single bird exhibiting isolated neurological signs. Proper evaluation must always integrate the case history, the mortality pattern, and the full post‑mortem lesion profile.
The recently recorded video shows a bird that is clearly not a Newcastle disease case, and the caption beneath it provides additional clarification regarding the potential non‑ND causes of torticollis. The name of the video is Newcastle Disease 030 in the section "Newcastle disease" of videos.
