I'm so sorry to hear about Eleanor.
Please do let me know what the results from UC Davis determines.
I'm going to read your report and try to comment/offer suggestions, but I'd recommend you delete your pdf, mark through/black out your personal info and the re-upload.

1. Gout: urate deposition on lung, liver, spleen, oviduct
a. Urate tophi with mild heterophilic and histiocytic interstitial nephritis, and tubular degeneration
2. PCR for AI did not detect the pathogen.

Preliminary report 03/06/2024:
There was not microscopic evidence compatible with a lymphoproliferative disease, intead there macroscopic lesions are
attributed to the urate deposition observed under the microscope. This deposition of urate crystals on serous surface of viscera
is either associated to impaired excretion by the kidneys (dehydration) or over production (excessive dietary protein or calcium).
An updated report will be shared.
Preliminary report 03/05/2024:
While the macroscopic changes in the kidney suggest a possible lymphoproliferative disease, there were other changes in the
heart and intestines that suggested a possible dehydration or deposition of urates, an updated report will be shared once the
ancillary tests are done.

trimethoprim Sulfamethoxazole 100 mg x 2, meloxicam 7.5 mg 1/4-tab x 2. Eleanor recovered. Mites May 2023, full recovery.
Eleanor is 1 yr. 11 months old. I raised her from 2 days old along with 5 other hens all same age. Given Monistat 2 ml x 2 day.

A hen is presented for necropsy on March 1st, 2025. Carcass is in good to fair postmortem condition and good body condition
based on the internal adipose stores (subcutis, mesentery, and epicardial). The hen is markedly dehydrated. The lungs are wet
and heavy, the air sacs are cloudy. The pericardial sac is cloudy and covered by a large amount of chalky white material. The
crop has a small amount of mucoid white material. The proventriculus has a small to medium number of seeds. The intestines
have a small amount of watery yellow to green content throughout. The serosa of the intestines is covered by a medium amount
of gritty material. The liver is friable and the gallbladder has a small amount of green watery material. Similar white material
observed in the serosa of the small intestines is observed covering the capsule of the spleen. The left kidney is enlarged,
multilobulated and pale. There is a retained egg shell in the celomic cavity. Both sciatic nerves are mildly edematous.
Tissues examined include conjunctiva, choana, air sacs, larynx, trachea/syrinx, lung, heart, ovary, adrenal gland, skeletal
muscle, esophagus, crop, proventriculus, ventriculus, liver, pancreas, intestine, spleen, sciatic nerves (left) and brain

Kidney: The section is effaced by diffuse areas of necrosis and hypocellularity and degeneration of the epithelial cells in the
tubule. Within these areas, and expanding the tubules there are colorless to basophilic radiating, sharp, acicular, crystalline
deposits (urate tophi).
Liver: There are multifocal areas of necrosis that coalesce, these foci are composed of colorless to basophilic to pale eosinophilic
radiating, sharp, acicular, crystalline deposits (urate tophi).
Similar urate tophi are observed in the lung, spleen, and oviduct, along with macrophages, heterophils, lymphocytes and fibrin.
Tissues examined include brain, sciatic nerves, brachial plexus, ovary, liver, kidney, lungs, heart, thymus, air sacs,
proventriculus, pancreas, small intestine, and colon
