FINAL DIAGNOSIS: PENDING MORPHOLOGIC DIAGNOSIS: TRACHEA: mild catarrhal tracheitis ORAL CAVITY: focal, pale yellow plaque
COMMENTS: The lesions noted on gross anatomic evaluation were mild and may not explain the clinical signs seen in this hen; however, this chicken had a high positive serologic titer to Mycoplasma gallisepticum indicating prior or ongoing infection with this bacteria which could have caused or contributed to the clinical signs. Histopathology is pending. Serologic testing of blood from live birds for M. gallisepticum is also available through the CVMDL and is recommended if further screening of the flock for exposure to this agent is desired; testing multiple birds is the most reliable method for detection of a flock issue.

GROSS FINDINGS: A young adult, brown and silver-laced, Dark Brahma hen weighing 1.6 kg was presented live for euthanasia and necropsy in good body condition. On clinical exam, this hen exhibited Owner:
Pg #:2 Accession No: 16 -6006 Dorothy Healy occasional open-mouth breathing and unusual clucking sounds associated with head-shaking. On the oral mucous membrane just aboral to the right oral commissure, there was a focal, ovoid, 0.2 X 0.1 cm, pale yellow plaque. There was a scant amount of pale tan mucoid material within the lumen of the trachea. The ovary and oviduct were small and inactive. The crop was mildly dilated and contained yellow, thick liquid with admixed soft, small, irregular, white to yellow pieces of food material and an abundance of intact, black, hard-shelled, ovate seeds; similar content filled the lumen of the esophagus distal to the crop. The ventriculus contained a moderate amount of brownish-yellow, granular ingesta with admixed grit. The small intestine had a moderate amount of brown, thick liquid digesta. The ceca contained a small amount of soft, brown fecal material. The colon had scant content.
