This study aimed to investigate the distribution and epidemiological relatedness of methicillin-resistant Staphylococcus aureus (MRSA) isolates from companion dogs, owners, and residential environments of 72 households. Sampling was performed twice from January to June 2018 and a total of 2,592 specimens were collected. The specimens collected from each household were streaked on CHROM agar Staph aureus and the colonies grown on the medium were further identified using a mass spectrometry microbial identification system. Antimicrobial susceptibility testing, Panton-Valentine-Leukocidin (PVL) gene PCR, staphylococcal cassette chromosome mec (SCCmec) typing, Staphylococcus aureus Protein A (spa) typing, pulsed-field gel electrophoresis (PFGE), and multi-locus sequence typing (MLST) were conducted to evaluate the phenotypic and genotypic characteristics of the MRSA isolates. A total of 65 S. aureus strains (2.5%) were isolated and 49 (1.9%) of 65 strains were MRSA displaying cefoxitin-resistance with mecA carriage. MRSA strains were isolated from dogs (n=6, 9.2%), owners (n=27, 41.5%), and residential environments (n=16, 24.6%), respectively. Overall prevalence of non-duplicated MRSA was 16.7% (12/72 households) at household level. ST72-SCCmec IVc MRSA clones predominantly appeared in MRSA-positive families. Furthermore, PFGE analyses showed that ST72-SCCmec IVc-t324 is shared between dog owners and dogs. To our knowledge, this is the first study to report the sharing of ST72 MRSA between dogs and their owners.

The purpose of this study was to assess the normal distribution of 18F-fluoro-2-deoxy-D-glucose (FDG) uptake of canine brain structures using a high-resolution research tomography-positron emission tomography (HRRT-PET) and 7 T-magnetic resonance imaging (MRI) fusion system. FDG-PET and T2-weighted MRI of the brain were performed on 4 healthy laboratory beagle dogs. On MRI, regions of interests (ROIs) were manually drawn over 51 intracranial structures, including nine gross structures and 42 detailed structures. Relative standard uptake value ratio (rSUV=SUV of ROI/SUV of whole brain) was calculated for each ROI. The HRRT-PET and 7 T-MRI fusion imaging system demonstrated significant differences in glucose metabolism among various intracranial structures. Among gross structures, the midbrain and the pons and medulla oblongata had the highest uptake (rSUV: 1.12 ± 0.03) and lowest uptake (rSUV: 0.90 ± 0.06) of FDG, respectively. When rSUVs were calculated on detailed regions, the caudal colliculus and the longitudinal fibers of pons had the highest (rSUV: 1.62 ± 0.05) and the lowest (rSUV: 0.63 ± 0.03) glucose metabolism, respectively. Because the high resolution of PET-MRI fusion images provided clearly identifiable metabolic activities of canine brain, the HRRT-PET and 7 T-MRI fusion imaging might be a good tool for evaluation of intracranial diseases in canines.

A 7-year-old intact female Maltese dog was referred with ptyalism and intermittent vomiting but no regurgitation for over 1 month. Survey radiographs including a contrast study revealed a large circular dilated cavity from the carina to the diaphragm. Additionally, multi-detector computed tomography and three-dimensional reconstruction were performed. These images revealed large idiopathic distal esophageal diverticula. This case report represents the first report using multi-detector computed tomography and three-dimensional reconstruction for evaluation of esophageal diverticula in a dog.

A 4-year-old intact female Pekingese dog was presented with ataxia and seizure episodes. Based on magnetic resonance imaging and cerebrospinal fluid analysis results, meningoencephalitis of unknown etiology was suspected. The present case survived for 1,096 days under cyclosporine plus prednisolone therapy and was definitively diagnosed with necrotizing meningoencephalitis. This report describes the clinical findings, serial magnetic resonance imaging characteristics and pathologic features of a necrotizing meningoencephalitis and long-term survival after cyclosporine with prednisolone therapy.

A 6-year-old ShihTzu presented with tonic-clonic cluster seizure. T2-weighted magnetic resonance (MR) images showed bilateral diffuse hyperintense lesions at the cerebral cortex with enlarged sulci. Computed tomography revealed a portosystemic shunt (PSS) and azygos continuation. Based on the clinical signs, blood examinations and diagnostic images, the dog was diagnosed with hepatic encephalopathy secondary to PSS. The neurologic signs were gradually improved after medical therapy for hyperammonemia. This is the first report of hyperintensity of the cerebral cortex on T2-weighted MR images associated with acute hepatic encephalopathy in a dog.

A 14-year-old Maltese dog presented for complete medical examination due to intermittent vomiting and diarrhea observed during the previous two days. A single, solitary, lobulated cystic mass was observed in the liver upon ultrasonographic and computed tomographic examination. After surgical hepatic resection to remove the mass, histological examination revealed a multilocular cyst lined by cuboidal to columnar epithelial cells, which is consistent with biliary cystadenoma. Here, we report the clinical, clinicopathological, histopathological, and diagnostic imaging findings of biliary cystadenoma in a dog.

A 5-year-old female Chihuahua dog was presented for acute collapse. Laboratory examinations showed markedly elevated levels of hepatobiliary enzymes. Empiric antibiotic therapy for bacterial infection of the liver was ineffective. The clinical signs worsened with the development of hyponatremia with hypo-osmolality and elevated urine sodium levels. The dog was suspected to have acute cholangiohepatitis associated with an immune-mediated disease. Subsequently, it was diagnosed with syndrome of inappropriate antidiuretic hormone secretion (SIADH) on the basis of the specific disease criteria. Further tests showed normal function of the adrenal and thyroid glands, and MRI and cerebrospinal fluid (CSF) analysis did not show any intracranial diseases. Immunosuppressive therapy and water restriction resolved the clinical signs and improved the SIADH in this dog. This case indicates that SIADH can occur concurrently with suspected immune-mediated liver disease in dogs.

An 8-year old intact female dog was presented with a sudden onset of unilateral hindlimb paralysis of 3 days duration. Based on the history and results of physical, neurological, histopathological examination, and blood work, an arterial thrombosis was suspected as a complication of the hypercoagulability from malignant mammary gland tumor. The thermography provided the evidence of the unilateral femoral thrombus. Initially, thrombolysis with streptokinase administered by intravenous infusion was ineffective. Thereafter, the direct delivery of streptokinase to the site of thrombus was attempted and it was curative. These results suggest that the thermography could describe the site of the arterial thrombus, and local intra-arterial administration of streptokinase may be an effective therapy for the canine arterial thrombosis complicated by malignant mammary gland tumor.

A 7-year-old, 1.76 kg Maltese dog presented with a 4-year history of a chronic pustular lesion and a wet cough. Erosive lesions were seen at the left thoracic wall. Radiology and computed tomography (CT) revealed a bronchocutaneous fistula connecting from the left cranial bronchus to the skin. On definitive surgery, a long wooden toothpick was observed within this tract, and clinical signs resolved after retrieval of the foreign body. Three-dimensional CT was useful to identify the characteristics of the bronchocutaneous fistula However, the wooden foreign body was not apparent on CT. Here, we report the clinical, clinicopathological and diagnostic imaging findings of a chronic bronchocutaneous fistula caused by a foreign body in a dog.
