and Relevance: This case supports the value of imaging, clinicopathologic assessment, and histopathology in diagnosis, and suggests that supportive husbandry modification may provide temporary welfare benefit in affected snakes.

Coelomic distension and lethargy were confirmed in a budgerigar and a helmeted guineafowl. Clinical evaluation suggested salpingitis and metritis in the budgerigar, while radiographic examination confirmed egg binding in the helmeted guineafowl. The budgerigar performed the salpingohysterectomy, keeping the anesthesia time short and being careful to hemostasize small vessels. The helmeted guineafowl was initially operated on for a left coelomic hernia due to egg binding. An additional operation was required as a cloacal prolapse occurred after laying. In this second surgery, to treat cloacal prolapse and prevent recurrence, a cloacal prolapse was repaired by anchoring the cloaca to the right pleura and performing simultaneously an asymmetric cloacoplasty on the right side.

Objective: This study aimed to assess the utility of symmetric dimethylarginine as a biomarker for kidney disease in captive striped skunks in Korea. Methods: This retrospective study analysed 11 striped skunks housed at the Everland Zoo between 2017 and 2021. Blood samples were collected during health checks. Kidney function was assessed through blood analysis and diagnostic ultrasound, with necropsies conducted on deceased animals. Symmetric dimethylarginine levels were measured in 27 plasma samples collected from 11 skunks. Results: Over the study period, seven skunks were diagnosed with kidney disease. Analysis of 27 blood samples revealed a concurrent increase in SDMA levels with concentrations of blood urea nitrogen and blood creatinine. In 3 of the 7 skunks with kidney disease, symmetric dimethylarginine exceeded 14 µg/dL prior to the elevation of blood urea nitrogen and blood creatinine above the upper reference limit. Conclusions and Relevance: To our knowledge, this is the first study investigating symmetric dimethylarginine in captive striped skunks in Korea. Our findings suggest that symmetric dimethylarginine may serve as an early and consistent biomarker for renal dysfunction in striped skunks. Further studies with larger clinical sample size from striped skunks are needed to validate the clinical utility of blood symmetric dimethylarginine concentration.

Two Whooper swan (Cygnus cygnus) died after suffering from pododermatitis, lethargy, and ataxia; necropsy was performed. Grossly, the liver was swollen and firm. The kidney and spleen were also enlarged and a pale tan color. On histopathologic examination with Congo red staining, amyloidosis was noted in liver, spleen, and kidney. In addition, marked osseous metaplasia was present in the liver. Based on these results, systemic amyloidosis involving liver, spleen, and kidney with osseous metaplasia in the liver was diagnosed. Study results indicate that an inflammatory reaction associated with pododermatitis had a role in the amyloidosis in this particular case.
