Evaluation of serum protein electrophoresis and immunofixation in dogs seropositive for various vector-borne pathogens.

Background: Canine vector-borne diseases (VBDs) induce non-specific dysproteinemias, detectable by serum protein electrophoresis (SPE). VBDs have been reported to induce a monoclonal gammopathy pattern. Monoclonal gammopathies are commonly the result of paraprotein (M-protein) produced by an immunoglobulin-secreting neoplasm.

Performance of the Sysmex XN-V hematology analyzer in determining the immature platelet fraction in dogs: A preliminary study and reference values.

Background: Immature platelets (IPs) are newly formed platelets released into circulation that have been demonstrated as good markers of thrombopoiesis. Although many flow cytometric and fully automated-based methods are available, the latest Sysmex XN-V hematology analyzer for veterinary use is equipped with a specific fluorescent platelet channel (PLT-F) that detects platelets using a platelet-specific dye.

Objectives: The aims of this study were to evaluate the performance of the Sysmex XSN-1000 V in determining the IPF (immature platelet fraction) and other selected PLT-F channel parameters and to propose IPF reference intervals (RIs) for canine blood samples.

Signalment, Immunological and Parasitological Status and Clinicopathological Findings of -Seropositive Apparently Healthy Dogs.

Canine leishmaniosis caused by is a disease with a wide range of clinical manifestations. Epidemiological serosurveys performed in Europe often lack a thorough assessment of clinical health status of studied dogs. The aim of this study was to evaluate signalment, immunological and parasitological status and clinicopathological findings of -seropositive apparently healthy dogs (n = 212) living in endemic areas.

Needle tract seeding and malignant transformation of hepatocellular adenoma into well-differentiated hepatocellular carcinoma in a dog.

An 11-year-old neutered female Golden Retriever was referred for investigation of marked increases in liver enzyme activities. Abdominal ultrasound revealed a large pedunculated liver mass. Diagnosis of hepatocellular adenoma (HCA) was made when the mass was excised after a first unsuccessful attempt through ultrasound-guided core-needle biopsy.

Undifferentiated Wing Sarcoma in a Peach-Faced Lovebird (Agapornis roseicollis).

A 10-year-old peach-faced lovebird (Agapornis roseicollis) was evaluated for an ulcerated and painful mass at the location of a fracture 2 years previously. Whole body radiographs showed a humeral fracture with a presumptive neoplastic proliferation in the distal diaphysis. Right wing amputation was elected but the animal died during recovery from surgery.
