A neutered male Golden Retriever was referred with a 2-week history of dry mouth. Multiple and bilateral enlargement of the lacrimal and salivary glands showing heterogeneous internal enhancement was identified on contrast-enhanced computed tomography (CT). Ultrasonographic examination detected multifocal hypoechoic areas within the swollen submandibular salivary glands, which were histopathologically diagnosed as lymphoplasmacytic sialoadenitis. As both imaging and histopathological findings were in accordance with those in human Sjögren’s syndrome, a provisional diagnosis of Sjögren’s-like syndrome was made. Immunosuppressive drugs promptly improved clinical signs concurrently with the abnormal sonographic findings, indicating the feasibility of ultrasonography in monitoring therapeutic outcomes. Herein, we discuss a proposed criteria set for diagnosis of Sjögren’s-like syndrome in veterinary medicine.

A definitive diagnosis of focal liver lesions (FLLs) requires invasive procedures for histopathologic examination. Thus, a simpler noninvasive diagnostic method, such as conventional ultrasonography combined with clinical data, is needed for the prediction of liver malignancy. The objective of this study was to examine the diagnostic accuracy of clinical data and ultrasonographic (US) features to differentiate benign and malignant liver lesions. Medical records and US images from dogs with FLLs that underwent abdominal US and histopathologic examinations following surgery or liver biopsy were retrospectively reviewed. Clinical data, including signalment, clinical signs and laboratory findings, and the US features of liver lesions that could act as predictive factors were assessed using univariate and multivariate analyses to evaluate the associations between predictive factors and liver malignancy. Based on the histopathologic results, 55 dogs with malignant lesions and 28 dogs with benign lesions were included in the study. The results of univariate analysis showed that several US features and platelet count were significantly associated with liver malignancy. Multivariate analysis revealed that the platelet count (thrombocytosis; odds ratio [OR]: 4.13, 95% confidence intervals [CI]: 1.81–9.41), lesion size (4.1 cm or greater; OR: 23.83, 95% CI: 3.74–151.95) and echotexture of FLLs (heterogenous; OR: 8.44; 95% CI: 1.37–51.91) were independent predictors for differentiating benign and malignant liver lesions, suggesting that a combination of clinical data and US findings of FLLs could predict liver malignancy in dogs.

Maintaining a good ventricular systolic function is important in the long-term therapy of dogs with supraventricular tachyarrhythmia (SVTA). The objective of this study was to evaluate the inhibitory effect of telmisartan on myocardial injury and the resulting ventricular systolic dysfunction in a canine model of SVTA. A total of 14 dogs were randomly assigned to a Telmisartan (oral telmisartan, 1.0 mg/kg daily, n=7) or a Control (no drug administration, n=7) group; the duration of rapid atrial pacing (RAP) was 3 weeks for both groups. The cardiac troponin I (cTnI) concentration in the Control group was significantly increased after 3 weeks compared to that before RAP initiation (baseline), but no significant difference was observed in the Telmisartan group. Moreover, the cTnI concentration at 3 weeks was significantly lower in the Telmisartan group than in the Control group. The left ventricular fractional shortening was significantly decreased at 3 weeks compared to that at baseline in both groups. However, fractional shortening at 3 weeks was significantly higher in the Telmisartan group than in the Control group. The cardiac output values in the Control group were significantly decreased at 3 weeks compared with those at baseline, but no significant difference was observed in the Telmisartan group. This study demonstrates that telmisartan inhibits the reduction in ventricular systolic function and prevents myocardial injury in a canine model of SVTA. Therefore, telmisartan is suggested as a novel treatment for canine SVTA.

Thoracolumbar intervertebral disk herniation (TL-IVDH) with caudal articular process anomalies has been reported in Pugs. It currently remains unclear whether congenital caudal articular process aplasia/hypoplasia predisposes to the development of TL-IVDH. However, there are difficulties in proving the causal relationship between caudal articular process anomalies and TL-IVDH. The aim of this study was to describe the prevalence of TL-IVDH at the vertebral space containing anomalous and normal caudal articular processes in Pugs. Fifty-seven pugs were eligible to be included in this study. Caudal articular process aplasia/hypoplasia affected 52/57 (91.2%) dogs. The caudal articular process anomalies were most frequently located between T10 and T13. Colocalization of caudal articular process aplasia/hypoplasia and TL-IVDH was detected in 11 dogs (19.3%). The prevalence of TL-IVDH at vertebral spaces containing abnormal caudal articular processes was 12.3%, whereas the prevalence of TL-IVDH at vertebral spaces containing normal articular processes was 2.4%. With the increase in the number of vertebrae with caudal articular process anomalies, the prevalence of TL-IVDH also increased. The results of this study suggested the prevalence of caudal articular process anomalies was high in Pugs. The caudal articular process anomalies could be associated with TL-IVDH. A large cohort is needed to prove the causal relationship between caudal articular process anomalies and TL-IVDH.

The purpose of this study was to evaluate the cardiac acute volume loading effect on left atrial (LA) strain and strain rate (SR) parameters derived from two-dimensional speckle tracking echocardiography (2D-STE) in healthy dogs. Six healthy beagles were anesthetized and subjected to increase cardiac preload by intravenous infusion with lactated Ringer solution at 150 ml/kg/hr for 90 min. A Swan-Ganz catheter was placed to directly measure the mean pulmonary capillary wedge pressure (PCWP). Echocardiography was performed before (baseline) and at 15, 30, 45, 60, 75, and 90 min after acute volume loading began. Apical 4-chamber images focused on the LA were digitally recorded for later strain and SR analysis via 2D-STE. Acute volume loading significantly increased from baseline during LA strain and SR as assessed by the speckle tracking–based technique during reservoir and conduit function at 15 to 90 min after volume load began, and strain indices representing booster pump function were enhanced at 45 to 90 min. In addition, acute volume loading resulted in a significantly greater PCWP after fluid infusion. On multiple regression analysis, quadratic regression analysis was a better fit for the relationship between PCWP and all LA functional indices. Our findings indicated that LA function analyzed by strain and SR was enhanced during cardiac acute volume loading in healthy dogs. The change in strain and SR during acute volume loading should be interpreted with caution during the diagnosis of heart diseases related to volume overload.

Strangles is a commonly diagnosed and important infectious disease of equids worldwide, caused by Streptococcus equi subsp. equi. We determined the SeM genotypes of S. equi isolated from imported horses at the Japanese border within the past 8 years, which allowed us to classify 12 strains isolated from these horses from each exporter into four allelic groups. These alleles were different from the alleles of past isolates found in Japan. Furthermore, four strains classified into the same allele were isolated from horses from one exporter over several years. In this study, S. equi isolates from different exporters had different SeM alleles. Attention to the hygiene status of farms will be necessary to prevent the incursion of strangles.

Periodontal disease is a significant problem in companion animals such as dogs and cats. However, there is little information available about fimbriae association of periodontal disease in companion animals. In this study, we have purified and characterized a fimbriae from P. salivosa ATCC 49407. The molecular mass of this protein was approximately 60-kDa, as estimated by SDS-PAGE. Immunogold electron microscopy revealed that anti-60-kDa fimbrial serum bound to fimbria on the cell surface of P. salivosa ATCC 49407. However, fimbriae of P. gingivalis and P. gulae were not labeled with the same antibody. Immunoelectron-microscopic studies and immunoblot analysis revealed that antigenicity and molecular weight were distinct from previously reported Porphyromonas fimbrial proteins. The amino acid sequence of the N-terminal 15 residues of the 60-kDa fimbrillin protein revealed only 3 of 15 residues identical to other Porphyromonas species fimbrillin proteins. Thus, the N-terminal amino acid sequence of the 60-kDa fimbrillin protein of P. salivosa clearly differed from previously reported fimbrillin proteins. The level of adherence of the P. salivosa was 1.81%. It was confirmed that P. salivosa can adheres to human cells. These results suggest that the 60-kDa fimbriaeof P. salivosa ATCC 49407 is a new type of fimbria and may have an important factor in the adherence host cells. We suggest that the surface structure of P. salivosa may have a role in the colonization of this organism in periodontal pockets in companion animals.

The emergence and spread of aminoglycoside-resistant bacteria are a public health concern. The acquisition of the genes encoding 16S rRNA methylases, such as armA, rmtA, and rmtB, confers high-level resistance to aminoglycosides. However, the prevalence has not been well investigated in Japanese veterinary fields. To determine the prevalence of 16S rRNA methylases in animals, we detected 16S rRNA methylases genes in Gram-negative bacteria from animals. Here, we report the isolation of rmtB amd armA from two of the 446 Escherichia coli (0.5%) and one of the 103 Klebsiella spp. isolates (1.0%) from companion animals, respectively. However, none of the isolations were observed from 2445 E. coli isolates derived from livestock in Japan. The prevalence of 16S rRNA methylases in animals, especially in companion animals, should be carefully monitored in Japanese veterinary fields to avoid the spreading of the genes.

Thirty-seven specimens of wild boar sera were collected from August 2016 to March 2018 in Ishikawa prefecture, Japan. Thirty-two specimens (86.5%) were positive for neutralizing antibodies against Japanese encephalitis virus (JEV). Eight specimens (21.6%) were positive for IgM antibodies against JEV. One sample was obtained from a wild boar captured in February during the winter season. Four other serum specimens obtained during the winter season were positive using a JEV gene-specific PCR assay. Based on IgM and PCR assays, wild boars were infected with JEV during the winter season, suggesting that the prevalence of JEV antibodies in wild boars in Ishikawa is high and JEV activity is possible during winter in this region. In addition, wild boars may play an important role in the infection cycle of JEV.

Mesothelioma is a very aggressive malignant tumor with low survival rates that is often diagnosed belatedly. Pericardial effusion is a common consequence in cases of mesothelioma, with pericardiocentesis and pericardiectomy indicated; therefor thoracocentesis is necessary to drain the contents no longer retained in the pericardium. The present report describes a mesothelioma – carrying dog with a history of cardiac tamponade that underwent thoracoscopic pericardiectomy and, later, thoracoscopic implantation of a fully implantable catheter to function as a thoracic drain. In the consulted literature, there is no use of a fully implantable catheter for this purpose. The authors consider that there was an improvement in the quality of life.

In an 8-year-old Labrador Retriever with progressive anorexia, constipation, and depression, CT revealed intussusception of the cecum into the ascending colon and a small cecal mass showing strong enhancement on arterial phase. The ileocecocolic junction was surgically resected and histologically diagnosed as cecocolic intussusception with carcinoid tumor. The carcinoid tumor worked as a lead point of intussusception in this case. Dual phasic CT is useful to assess the presence of gastrointestinal tumors as lead points in old dogs with intussusception.

A new reassortant H7N3 avian influenza virus (AIV) was isolated from a duck meat product that was illegally taken on board a passenger flight from China to Japan in March 2018. Sequencing analysis revealed that the H7N3 isolate, A/duck/Japan/AQ-HE30-1/2018 (Dk/HE30-1) (H7N3), was a reassortant highly pathogenic avian influenza virus (HPAIV) that contained the haemagglutinin (HA) gene of Chinese H7N9 HPAIV. Dk/HE30-1 (H7N3) possessed a novel polybasic sequence motif PEVPKRRRTAR/GLF at the HA cleavage site that has never previously been reported in H7 HPAIVs. The HA antigenicity of Dk/HE30-1 (H7N3) slightly differed from that of H7N9 HPAIVs previously reported. These findings will help further our knowledge of the circulation and genetic evolution of emerging AIVs in endemic areas.

Tyrosine hydroxylase (TH) is the rate-limiting enzyme of dopamine (DA) biosynthesis, which is up-regulated by vitamin C administration. Nurr1 gene is highly expressed in brain and important for midbrain DAergic cell development and survival. But, the role of vitamin C and/or vitamin E during Nurr1 expression is yet to be known. Further, the synergistic effect of vitamins C and E on TH expression has not yet been explored clinically. Therefore, we studied the effects of single or co- administration of vitamin C (0.5 mM) and vitamin E (1 mM) for 72 hr, on both TH and Nurr1 expression in in vitro primary cultured gestational days (GD) 13.5 rat ventral mesencephalon (VM) by Western blot and immunocytochemistry. Our study revealed highest expressions of both TH and Nurr1 in the vitamin C + vitamin E treated group. TH expression was also increased in the vitamin C treated group than that of the control group, but the vitamin E treated group did not show any statistically significant effect. However, both the vitamin C and the vitamin E treated groups revealed increased expression of Nurr1 protein as compared with the control group. The present experimental data suggest that vitamin C can up-regulate the protein expression of TH, but Nurr1 level was elevated either by vitamin C or by vitamin E administration. Further, vitamin E acts synergistically with vitamin C to elevate TH and Nurr1 expression, which is the most novel finding of our study and for the first time; we reported this result, since there have been no published data on the synergistic effect of both the antioxidant vitamins on TH and Nurr1 expression in VM. As the motor function defect due to the progressive loss of DAergic neuron is the major reason of Parkinsonism, therefore, the results of our study finally suggest the effective role of vitamin C and vitamin E during early treatment of Parkinsonism.

This study investigated the direct effects of non-steroidal anti-inflammatory drugs (NSAIDs) and atrial natriuretic peptide (ANP) on canine-derived vascular endothelial cells (VECs). VECs were isolated and cultured from canine arteries and veins. The mRNA expressions of vascular endothelial growth factor receptor 2, cyclooxygenase-2, and natriuretic peptide receptor 1 were detected in the cultured VECs. The viability of the cultured VECs was reduced in a dose-dependent manner by meloxicam, carprofen, and robenacoxib. By contrast, dose escalations of ANP had only marginal influence on the viability of cultured VECs. NSAIDs may potentially serve as not only analgesic agents against cancerous and perioperative pain but also as adjuvant anti-angiogenic drugs in dogs with malignant tumors.

Phosphofructokinase-1 (EC:2.7.1.11, PFK-1) catalyzes the phosphorylation of fructose 6-phosphate to fructose 1,6-bisphosphate using adenosine triphosphate and is a key regulatory enzyme of glycolysis. Mammalian PFK-1 isozymes are composed of three kinds of subunits (PFK-M, -L, and -P), with different properties. It has been suggested that the proportion of PFK-1 subunits in different organs is based on the organ energy metabolism. In this study, we analyzed the activity and subunit composition of canine PFK-1. We found that, in dogs, the skeletal muscle only has PFK-M, the liver mainly has PFK-L, and the brain expresses all of them. The knowledge of the composition of PFK-1 could provide useful information for determination of the differences in glycolysis in various organs of dogs.

This is the first study of using sublingual mucosae to establish a new urination passage in male cats suffering from complications from prior urethrostomy. In total, five domestic male cats afflicted with various complications, such as urethra stricture, scalding dermatitis, and urinary tract infection, after urethrostomy were included in the study. Sublingual mucosa was harvested to graft with abdominal muscles and further made into a tube connecting with the remaining urethra of the bladder at the cranial end and with the prepuce at the caudal end, serving as a new passage for urination. Postoperatively, all cats were alive and well recovered with no complications both in the oral cavity and at the surgical site. Radiography with contrast medium at two weeks and six months after surgery showed no leakage, stricture, or abnormality of the new urination passage. Moreover, all cats were able to urinate from the prepuce without any difficulty or signs of discomfort.

A tumor had formed in the right eye of a 14-year-old male chinchilla. The black-and-white-colored tumor occupied the entire eye except for the lens and had invaded extensively inside the orbit. Histologically, round, spindle- to polygonal-shaped tumor cells had proliferated in a solid-sheet arrangement. The tumor cells exhibited polymorphic nuclei ranging from round- to polygonal-shaped, as well as abundant cytoplasm, which occasionally contained melanin granules. In some areas, several cells were surrounded by the basal lamina. Additionally, the tumor showed cervical lymph-node metastasis. Upon immunostaining, the tumor cells were positive for epithelial markers (cytokeratin AE1/AE3, 8/18, and 20), S100, and vimentin. Consequently, we diagnosed primary pleomorphic iridociliary adenocarcinoma with lymph-node metastasis. This is the first report of iridociliary adenocarcinoma in chinchillas.

A castrated male Shih-Tzu dog was presented for evaluation of urine leakage after urethrotomy. A fistula with urine leakage was identified in the perineal region. On retrograde urethrography, the contrast extravasated from the penile urethra into the subcutaneous tissue of the perineum. Urine leakage with urethrocutaneous fistula was diagnosed. During surgery, the disrupted urethra wall and two urethral defects were identified. A fascia lata autograft was used, rather than primary repair of the urethra. Two pieces of fascia lata were harvested and sutured to the urethral defects. The fistula was treated with debridement and drainage. No evidence of urine leakage and dysuria was noted 6 months postoperatively. Thus, this case report describes successful urethral reconstruction using a fascia lata autograft.

A 3.9-year-old female African pygmy hedgehog (Atelerix albiventris) had a firm, tan-colored mass with an uneven surface arising from the mandibular salivary gland. A histopathologic examination revealed that the mass was composed of neoplastic proliferation of epithelial and spindle cells. The neoplastic spindle cells showed positive for vimentin, smooth muscle actin, calponin and cytokeratin 14 and, negative for cytokeratin 19, suggesting that spindle cells were derived from myoepithelial cells. Based on the histological findings and immunohistochemistry results, the mass was diagnosed as pleomorphic adenoma. Pleomorphic adenoma is the most common benign tumor found in human salivary glands, but it is rare in animals. To the best of our knowledge, this is the first report of pleomorphic adenoma in hedgehogs.

Two Large Yorkshire piglets were diagnosed as persistent hyperplastic primary vitreous (PHPV). In case 1, the white cord-like structure extending from optic disc to lens was observed in the normal-sized right eye. Case 2 showed buphthalmos of the right eye. The internal structure of the right eye was unclear due to bleeding, but a white cord-like structure was slightly observed. In both cases, histological examinations revealed the fibrovascular cord-like structure in hyaloid vitreous. The retina was detached, and dysplastic nervous tissue was observed in anterior vitreous. Immunohistochemistry using various neural markers suggested that dysplastic nervous tissue was derived from the detached neural retina. By the characteristic macroscopic and histopathological features, both cases were diagnosed as PHPV. To our knowledge, this is the first report of swine PHPV.
