Hi, We had a hen die on us recently and sent the poor thing to UC Davis to be necropsied. The results came back today and I can decipher bits and pieces of it, but unsure if any of the diseases are contagious for my other hens. Here's the report. 1. Coelomitis, lymphohistiocytic with yolk protein; Proteus isolated. 2. Tracheitis, mild to moderate, diffuse lymphocytic. 3. Pneumoconiosis, moderate, multifocal 4. Fibrinous air sacculitis, lymphohistiocytic and granulocytic 5. Tubulointerstitial nephritis lymphocytic with multifocal mineral concretions. Ancillary test results: a. Proteus isolated from the coelom, liver and lung. b. Negative for avian influenza and enteric Salmonella by PCR. Ca s e S u m m a r y 08-28-14. This chicken had a coelomitis with free yolk protein throughout the abdomen. This likely started as an anscending infection of the oviduct. The Proteus may have been the primary bacteria but also may be contaminant and overgrew the primary bacteria. In addition, there was a tracheitis which may suggest there was an upper respiratory infection. Several agents can cause that including Mycoplasma, paramyxovirus or infectious bronchitis virus. Avian influenza and intestinal Salmonella PCR test results were negative. This completes testing on this case. G ro s s O b s e r v a t i o n s This hen is submitted in fair postmortem condition. She is thin. There is dirt and seeds in the crop. The oropharynx is unremarkable. The trachea is clear. The lungs are pink. The abdominal air sacs are opaque and there is Report 4.19-CAHFS Standard Report - 8/19/2014 Page 1 of 2 CAHFS Final Version 1 Accession # D1410350 August 28, 2014 brown thick fluid with yolk material in the coelomic cavity. The heart, liver, spleen, kidneys are unremarkable except for slightly swollen. The intestines are unremarkable. There is no bursa grossly present.
