Wry necks associated with Mycoplasma meleagridis infection in a backyard flock of turkeys.

Two 5-week-old bronze turkeys were submitted with crooked necks that could not be straightened. Both birds were serologically and culturally positive for Mycoplasma meleagridis (MM). Histologically, there were lymphoid follicles in the cranial thoracic and cervicoclavicular air sacs, and inflammatory changes in the cartilage of some cervical vertebrae. This appeared to be a case of MM-associated wry necks.
