Isolation of multidrug-resistant (MDR) Mycobacterium bovis from a dog in Korea.

A 3-year-old female Miniature Schnauzer dog with a week-long history of generalized intention tremor and progressive weight loss for several months was admitted. Mild anemia, fever, splenomegaly, aseptic cerebral meningitis and systemic lymph nodes enlargement were examined through erythrogram, ultrasonography, computed tomography and magnetic resonance imaging. Mycobacterium bovis was identified via molecular microbiology having the same molecular type as that of isolates from a cattle farm previously identified.

Evaluation of the Randox and Fuji Dri-Chem vcCRP-P assays of canine C-reactive protein.

In veterinary medicine, measurement of canine C-reactive protein (cCRP) is used widely to detect inflammatory diseases. We evaluated the precision of Randox and Fuji assays for cCRP, as well as accuracy, correlation, and agreement compared to a reference ELISA. Blood samples from 71 client-owned dogs (20 healthy, 51 diseased) were analyzed with the 3 assays.

Prevalence of Reticulocytosis in the Absence of Anemia in Dogs with Cardiogenic Pulmonary Edema Due to Myxomatous Mitral Valve Disease: A Retrospective Study.

Myxomatous mitral valve disease (MMVD) is the most common heart disease in small breed dogs. Dogs with MMVD commonly show clinical signs of dyspnea due to cardiogenic pulmonary edema (CPE). Reticulocytosis in the absence of anemia (RAA) is a hematological finding in hypoxic conditions.

AniScan Using Extracellular Cyclic AMP-Dependent Protein Kinase A as a Serum Biomarker Assay for the Diagnosis of Malignant Tumors in Dogs.

The early detection of tumors improves chances of decreased morbidity and prolonged survival. Serum biomarkers are convenient to use and have several advantages over other approaches, such as accuracy and straightforward protocols. Reliable biomarkers from easily accessible sources are warranted for the development of cost-effective assays for routine screening, particularly in veterinary medicine.

Multiple cutaneous plasmacytosis with multilobated (clover-leaf shaped) nuclei cells in a dog.

A 12-year-old female Shih-tzu dog was presented with a 2-month history of cutaneous non-pruritic multiple ulcerated or crusted nodules of less than 1.5 cm in diameter on eyelids, lips, abdomen, groin, thighs and perianal region. Several diagnostic tests were performed, including fine needle aspiration and skin biopsy of the cutaneous nodules.

Extracellular cyclic adenosine monophosphate-dependent protein kinase A autoantibody and C-reactive protein as serum biomarkers for diagnosis of cancer in dogs.

Protein kinase A, a cyclic adenosine monophosphate (AMP)-dependent enzyme, normally exists within mammalian cells; however, in cancer cells, it can leak out and be found in the serum. Extracellular cyclic AMP-dependent protein kinase A (ECPKA) has been determined to increase in the serum of cancer-bearing dogs. However, there have been no reports in the veterinary literature on serum ECPKA autoantibody (ECPKA-Ab) expression in dogs with cancer.

We describe a B-cell lymphoma of a submandibular lymph node with metastasis to the lung and facial subcutaneous tissues in a water deer ( Hydropotes inermis ). Neoplastic cells contained pleomorphic lymphocytes that were positive for CD79a, consistent with B-cell lymphoma. PCR for bovine leukemia virus was negative.

Diagnostic imaging features of normal anal sacs in dogs and cats.

This study was conducted to provide normal reference features for canine and feline anal sacs using ultrasound, low-field magnetic resonance imaging (MRI) and radiograph contrast as diagnostic imaging tools. A total of ten clinically normal beagle dogs and eight clinically normally cats were included. General radiography with contrast, ultrasonography and low-field MRI scans were performed.

A rare case of hepatic T-cell rich B-cell lymphoma (TCRBCL) in a juvenile dog.

A 7-month-old castrated male French Bull dog was presented with vomiting, lethargy, anorexia and weight loss of 2 weeks duration. The patient's history and clinical manifestations of suspected hepatopathy were subjected to ultrasonography, radiography, biochemical investigations and cytology of hepatic lesion. The cytologic impression was hepatic lymphoma, which was later confirmed by histopathology.

Multicentric epitheliotropic T-cell lymphoma in an African hedgehog (Atelerix albiventris).

A 2-year-old female African hedgehog was presented with a 5-month history of pruritus, and diffuse spine and hair loss. A dermatologic examination revealed erythema, excoriation, scales, and crusting affecting the face, flanks, forelimbs, hindlimbs, and dorsal and ventral abdomen. Fine-needle aspiration was performed and skin biopsies were taken from several lesions for cytologic and histologic evaluation.

Multiorgan fungal infection caused by Microsporum canis in a green iguana (Iguana iguana).

Multiple organ invasion by keratinophilic fungi in the green iguana (Iguana iguana) has not been previously reported. In this case, a 1-yr-old female green iguana presented with a nodular, darkly discolored skin lesion surrounded by necrosis in the right ventral abdominal region. A cytologic examination of the fine needle aspiration of the lesion revealed an exuberant proliferation of fibroblasts, macrophages, and multinucleated cells along with frequent filamentous structures consistent with hyphal elements.

An autochthonous case of canine visceral leishmaniasis in Korea.

A 12-year-old spayed female mixed-bred dog presented with nasal bleeding of 2 days duration and a skin nodule in the left flank. No abnormalities were found in coagulation profiles and blood pressure. Cytological evaluation of the nodule revealed numerous characteristic round organisms having a nucleus and a bar within macrophages and in the background, consistent with leishmaniasis.

Cytologic and immunohistochemical characterization of a primitive neuroectodermal tumor in the brain of a dog.

A 6-year-old intact female Pointer dog was presented for evaluation of acute onset of ataxia, circling, and head tilt. Neurologic assessment revealed overall decreased postural reaction, left-sided hemiparesis with incoordination, rigidity of fore- and hindlimbs, strabismus of the right eye, and bilateral horizontal nystagmus. Using magnetic resonance imaging, a mass lesion was identified in the cerebrum adjacent to the left side of the cerebellum compressing the brain stem ventrally.

Central nervous system relapses in 3 dogs with B-cell lymphoma.

This report describes cases of central nervous system (CNS) relapse that occurred during chemotherapy in 3 dogs with lymphoma. Diagnosis was made by a combination of clinical signs and cytology of cerebrospinal fluid. The suspected risk factors, clinical features common to the 3 dogs, and treatment options are discussed.

Successful treatment of an unusually large corneal epithelial inclusion cyst using equine amniotic membrane in a dog.

A 10-year-old intact male Yorkshire Terrier was referred for investigation of a large raised and nonpainful corneal lesion oculus dexter. Clinical examination revealed a pale, translucent corneal mass, which occupied half of the corneal surface and measured 11 mm x 11 mm x 13 mm. The mass was removed by superficial keratectomy and equine amniotic membrane (AM) was transplanted into the large corneal defect to cover the wound and provide tectonic support for the remaining cornea.
