A Japanese black cow aborted at the age of 270 days in October 2019. Necropsy showed edema and fibrin exudation in the thoracic cavity and white spotting in the liver. In the bacteriological examination, Salmonella enterica serotype Dublin (S. enterica Dublin) was isolated from the major fetal organs. Histopathological examination showed aspiration pneumonia and paratyphoid nodules in the liver with gram-negative bacilli accumulation. In the immunohistochemical examination, S. enterica Dublin antigen was detected, corresponding to gram-negative bacilli. These results suggest the abortion occurred from S. enterica Dublin. To our knowledge, there are many reports about abortion caused by S. enterica Dublin, but few about lesions on aborted fetal organs. In this case, observed paratyphoid nodules in the liver produced by S. enterica Dublin and these findings suggest specific pathogenesis on fetal organs caused by S. enterica Dublin.

Data from 117 cats (143 ureters) diagnosed with ureteral calculus obstruction from 2003 to 2018 at the Department of Nephro-Urology, Azabu University Veterinary Teaching Hospital, were retrospectively analyzed for surgical complications and outcomes. The incidence of surgical complications was lowest for ureterotomy (4.0%), followed by ureteroneocystostomy (27.1%), ureteral stenting (34.6%), and subcutaneous ureteral bypass (37.5%). All techniques resulted in a significant reduction in serum creatinine. The overall perioperative mortality was 1.8% in 109 cats that received radical surgery and was lower than previously reported. Preoperative percutaneous nephrostomy was useful to stabilize severely azotemic, high-anesthetic risk patients and to predict renal functional recovery after deobstruction. Because cats with ureteral calculi present with varying degrees of severity and signs of obstruction, the surgical approach should be individualized and optimized for each patient. Treatment is likely to be most successful if performed by a skilled surgeon who is proficient in all surgical techniques.

Six neoplastic discontinuous masses were found in a breeding sow slaughtered in Yamagata Prefecture, Japan. They occurred in the serosal surface of the ileum. Two were approximately 7×6×5 cm and the others were 2×1×1 cm in size. The surface was milky white, solid and elastic, and the cross-section showed the same color, organizing abscess and necrosis. Microscopically, the masses composed of spindle-shaped tumor cells, which had oval-to-spindle nuclei and abundant eosinophilic cytoplasm were arranged in streams and bundles. Mitosis was extremely rare. Immunohistochemically, the tumor cells were strongly positive for vimentin, KIT and DOG‐1, weak for α‐SMA, and negative for CK and S‐100. Based on histological and immunohistochemical findings, the masses were diagnosed as a gastrointestinal stromal tumor. To the best of our knowledge, this is the first report on GIST arising from ileum in a pig.
